The Genetics of Raw Carrots Liking

Aira on May 1, 2024

The humble carrot. A lunchbox staple, a bunny rabbit’s delight, and a surprising source of debate. People often find raw carrots irresistibly appealing, but what exactly makes them so likable?

There’s a certain satisfaction in biting into a crisp, cold carrot. The snap, the release of sweet, earthy flavor, the refreshing juice – it’s a sensory experience. Unlike some other vegetables, raw carrots are easy to grab and munch on, making them a convenient and healthy snack.

But why do some individuals find raw carrots more, or less, enjoyable than others?

Raw carrots liking

The Nutritional Powerhouse Within

Beyond taste and texture, raw carrots offer numerous health benefits, making them a nutritional powerhouse:

It’s worth noting that while some nutrients, like vitamin A, are readily absorbed from raw carrots, others, such as lycopene, become more bioavailable when carrots are cooked with a bit of fat.

Raw vs. Cooked Carrots

Unable to decide between raw or cooked carrots? The good news is, you don’t have to choose! Both preparations offer distinct advantages:

Ultimately, the best way to enjoy carrots is whichever way suits your preferences. Experiment with different cuts and dips to find your perfect carrot combination.

How Genetics May Influence Raw Carrots Liking

In 2022, a large-scale GWAS study of food liking identified 1,401 significant food-liking associations which showed substantial agreement in the direction of effects with 11 independent cohorts.

The study used genetic correlations combined with genomic structural equation modeling to create a multi-level map of the relationships between different food preferences, highlighting three main domains that they define as “Highly palatable”; including desserts, meat, and savory foods, “Low caloric”; including vegetables, fruit, and whole grains, and “Acquired” foods including unsweetened coffee, alcohol, cheese, and strong-tasting vegetables.

LifeDNA references this study to analyze specific genes in order to provide personalized insights into raw carrots liking. Genes with genetic variants (SNPs) associated with raw carrots liking include FTO (rs9972563), SEMA6D (rs11070592), and MSRA (rs2952186).

Genetic factors have been identified as associated with different facets of food preferences, potentially influencing our fondness for food through diverse channels linked to brain development, energy use, and our perception of rewards. Investigating the influence of genetic diversity on food preferences could offer insights into the genetic and neurological underpinnings of our culinary inclinations and choices, which are crucial for devising improved dietary strategies and crafting more enticing food selections.

Non-Genetic Factors Influencing Raw Carrots Liking

When considering the enjoyment of raw carrots, numerous factors beyond genetics contribute to shaping individual preferences and experiences:

  • Taste Sensitivity: Variations in taste bud sensitivity, particularly towards bitterness, can significantly impact one’s liking for raw carrots. Individuals with a heightened perception of the bitter compounds in carrots may find them less palatable, thus affecting their overall enjoyment.
  • Learned Preferences: Early experiences and cultural influences play a pivotal role in shaping dietary preferences. Exposure to raw carrots during formative years, coupled with positive associations, can foster a preference for this crunchy vegetable. Conversely, negative encounters or lack of exposure may lead to a dislike or indifference towards them.
  • Sensory Characteristics: The sensory aspects of carrots, encompassing texture, temperature, and visual appeal, contribute substantially to their overall appeal. Younger carrots, characterized by their sweetness and crispiness, are often favored over older, woodier ones that may lack the same pleasurable qualities.
  • Flavor Pairings: Pairing flavors strategically can enhance the appeal of raw carrots. Combining them with complementary companions such as hummus, ranch dressing, or cheese can transform the eating experience, making it more enjoyable and satisfying.

Suggestions on Preparing Raw Carrots

To optimize the enjoyment of raw carrots, individuals can consider the following practical tips:

  • Freshness: Opting for young, firm carrots with vibrant orange hues ensures optimal flavor and texture. Freshness enhances taste and contributes to a crispier texture, elevating the overall eating experience.
  • Cutting Style: Experimenting with different cutting styles, from sticks to ribbons or baby carrots, can introduce variety in texture and presentation. Varying the texture adds an element of surprise and interest to each bite.
  • Dipping Sauces: Offering an array of dipping sauces such as hummus, guacamole, or yogurt-based dips can enhance the flavor profile of raw carrots, making them more enticing and enjoyable.
  • Pairing with Other Vegetables: Pairing raw carrots with an assortment of colorful vegetables such as celery, bell peppers, or cucumbers not only adds visual appeal but also introduces a variety of textures and flavors, enriching the overall snack experience.

Eating Too Many Carrots

The notion that eating l carrots can result in an orange hue to the skin is a common misconception. While carrots are indeed rich in beta-carotene, the pigment responsible for their characteristic orange color, it’s highly unlikely that moderate carrot consumption will lead to such an effect.

Carotenemia, the condition in question, arises from an excessive intake of beta-carotene, which the body converts into vitamin A. However, rather than posing a significant health risk, excess beta-carotene is typically stored in fatty tissues, resulting in a subtle yellowish discoloration of the skin, particularly noticeable on the palms and soles. Fortunately, this condition is reversible and does not typically cause harm.

Note: Individuals with specific medical conditions, such as hypothyroidism or liver disorders, may need to exercise caution regarding their beta-carotene intake. Consulting a healthcare professional is advisable if there are concerns about dietary choices and their potential effects.

Are You Always Craving Sugary Drinks? Your Genetics May Be the Cause

Aira on May 1, 2024

Overview

Ever wondered why some people seem to crave sugary drinks more than others? Unraveling the genetic underpinnings of sugary drink consumption sheds light on this intriguing phenomenon.

Sugary drinks encompass a broad category of beverages laden with added sugars, including sodas, fruit juices, energy drinks, and sweetened teas. These beverages contribute significantly to daily caloric intake and have been linked to various adverse health outcomes, including obesity, type 2 diabetes, cardiovascular diseases, and dental issues. 

Recent scientific investigations suggest that individual preferences and consumption patterns for sugary drinks may be influenced by genetic factors, adding a new dimension to the understanding of dietary behaviors and their health consequences. 

By delving into the interplay between genetics and sugary drink consumption, researchers aim to figure out why some individuals are more prone to excessive intake, paving the way for personalized interventions and public health strategies. 

Why Do People Like Sugary Drinks?

Sugary drinks hold a magnetic allure for many, tempting taste buds with their sweet flavors and refreshing fizz. But what drives this widespread affinity? Scientific research offers a multifaceted understanding of why people are drawn to sugary beverages.

Firstly, our evolutionary history plays a role. Humans have an innate preference for sweetness, which likely stems from our ancestral diet rich in fruits and other natural sources of sugars. This preference was advantageous for survival, as it guided our ancestors toward energy-dense foods.

Moreover, the brain’s reward system comes into play. Consuming sugar activates the brain’s pleasure centers, triggering the release of neurotransmitters like dopamine, which create feelings of pleasure and satisfaction. This neurological response reinforces the desire to consume sugary drinks.

Cultural and environmental factors also contribute. Advertising, social norms, and availability heavily influence beverage choices. The ubiquitous presence of sugary drinks in supermarkets, restaurants, and vending machines further ingrains their appeal.

Individual differences in taste perception and genetic predispositions play a significant role. Some people may be more sensitive to sweetness or have a genetic predisposition that makes them crave sugary foods and drinks more intensely. Additionally, stress, emotional factors, and habit formation can drive consumption. Many individuals turn to sugary drinks as a source of comfort or as a habitual part of their daily routine.

Why are Sugary Drinks Unhealthy in Excessive Amounts?

Sugary drinks are deemed unhealthy due to their high sugar content and lack of nutritional value. Scientific research overwhelmingly links excessive consumption of sugary drinks to various adverse health outcomes. Here’s a breakdown of the dangers:

  1. Weight Gain and Obesity: Sugary drinks are high in calories but low in satiety, leading to excessive calorie intake without feeling full. This imbalance can contribute to weight gain and obesity, a well-established risk factor for various chronic diseases.
  2. Type 2 Diabetes: Regular consumption of sugary drinks is strongly associated with an increased risk of developing type 2 diabetes. The excessive intake of added sugars can lead to insulin resistance, impairing the body’s ability to regulate blood sugar levels effectively.
  3. Cardiovascular Diseases: Excessive sugar consumption, particularly in the form of sugary drinks, is linked to an elevated risk of cardiovascular diseases such as heart disease and stroke. High sugar intake can raise blood pressure, triglyceride levels, and inflammation, all of which are detrimental to heart health.
  4. Dental Issues: Sugary drinks contribute to tooth decay and cavities due to their high sugar content. The bacteria in the mouth feed on sugars, producing acids that erode tooth enamel and promote decay.
  5. Non-Alcoholic Fatty Liver Disease (NAFLD): Consuming too many sugary drinks can lead to the accumulation of fat in the liver, increasing the risk of developing NAFLD, a condition associated with liver inflammation and damage.

Limiting intake and opting for healthier beverage choices is essential for maintaining overall health and well-being.

Sugary Drink Consumption

Genetic Factors Affecting Sugary Drink Consumption

A 2019 GWAS sheds light on the genetic factors influencing our beverage choices, particularly when it comes to sweet and bitter drinks. Scientists conducted a study involving around 370,000 individuals of European descent to investigate the genetic basis of beverage consumption habits.

The study found that certain genes are linked to preferences for bitter-tasting beverages like coffee, tea, and alcoholic drinks such as wine and beer. Notably, variants near genes such as GCKR, ABCG2, and AHR were associated with increased consumption of bitter beverages. 

Further analysis revealed specific genetic links to a preference for different types of beverages. For instance, genes GCKR and ADH1B were associated with bitter alcoholic drinks, while gene variant (rs55872725) in  FTO was linked to sugar-sweetened beverage(SSB) preference A variant in the SEC16B gene had a suggestive association with coffee preference.

This research suggests that genetic factors previously known to be related to alcohol and coffee consumption, as well as obesity, play a significant role in shaping our preferences for bitter and sweet beverages. Further studies are needed to explore the specific genetic links to taste perception and their influence on beverage choices.

Environmental Factors Affecting Sugary Drink Consumption

Environmental factors play a pivotal role in shaping an individual’s sugary drink consumption habits. These external influences, ranging from cultural norms to accessibility, can significantly impact beverage choices. Let’s explore some of the key environmental factors backed by scientific evidence:

  1. Advertising and Marketing: The pervasive marketing of sugary drinks can strongly influence consumer behavior, especially among children and adolescents. Studies have shown that exposure to advertisements for sugary beverages is associated with increased consumption. Advertisements often depict these drinks as refreshing, fun, and associated with positive emotions, creating a powerful appeal.
  2. Price and Accessibility: Economic factors, such as the price and availability of sugary drinks, play a crucial role in consumption patterns. Research indicates that lower prices and widespread availability of these beverages are associated with higher consumption rates. Conversely, interventions like taxation or pricing strategies that increase the cost of sugary drinks have been shown to reduce consumption.
  3. Social and Cultural Norms: Cultural practices and social norms surrounding beverage consumption can heavily influence individual choices. For example, in societies where sugary drinks are deeply ingrained in social rituals or celebrations, their consumption may be more prevalent. Likewise, peer influence and social acceptance of sugary drinks can shape consumption behaviors, especially among young people.
  4. Portion Sizes and Packaging: The size and packaging of sugary drinks can impact consumption. Larger portion sizes and bulk packaging may encourage overconsumption by promoting the idea of “value for money” or by normalizing larger servings. On the other hand, interventions that reduce portion sizes or offer smaller packaging options can help moderate intake.
  5. Availability in Schools and Workplaces: The presence of sugary drinks in environments such as schools, workplaces, and recreational facilities can influence consumption patterns, particularly among children and adolescents. Research suggests that policies restricting the availability of sugary drinks in these settings can lead to reduced consumption and improved health outcomes.
  6. Cultural Preferences and Taste: Cultural preferences for sweet beverages, shaped by factors such as cuisine and culinary traditions, can influence individual consumption habits. Additionally, taste preferences developed early in life can persist into adulthood, impacting beverage choices.
  7. Nutritional Education and Awareness: Access to accurate nutritional information and education about the health risks associated with sugary drink consumption can influence behavior. Studies have shown that increased awareness of the adverse effects of sugary drinks can lead to reduced intake.

Environmental factors play a significant role in shaping sugary drink consumption patterns. Understanding these influences is essential for developing effective public health interventions and policies aimed at promoting healthier beverage choices and reducing the burden of related chronic diseases.

Are Sugary Drinks Addictive?

Sugary drinks exhibit addictive properties due to their impact on the brain’s reward system, similar to substances like drugs and alcohol. Over time, repeated consumption can lead to tolerance, requiring larger amounts to achieve the same level of satisfaction. 

Moreover, withdrawal symptoms may occur when sugary drinks are withheld, further indicating addictive potential. Signs of sugary drink dependence or addiction may include:

  • Cravings: Persistent and intense cravings for sugary drinks, often leading to compulsive consumption.
  • Loss of Control: Difficulty controlling intake, despite efforts to cut back or stop consumption.
  • Tolerance: Needing increasing amounts of sugary drinks to experience the desired effects or satisfaction.
  • Withdrawal Symptoms: Experiencing negative physical or psychological symptoms when attempting to reduce or stop consumption, such as headaches, irritability, or mood swings.
  • Continued Use Despite Negative Consequences: Continued consumption of sugary drinks despite being aware of the associated health risks or experiencing adverse effects such as weight gain, dental issues, or fatigue.

Research indicates that individuals vary in their susceptibility to sugary drink addiction, with factors such as genetics, brain chemistry, and environmental influences playing significant roles. Recognizing the addictive nature of sugary drinks is crucial for developing effective interventions and policies aimed at reducing consumption and mitigating associated health risks.

How to Lessen Sugary Drinks Cravings

Reducing sugary drink consumption is essential for maintaining overall health and preventing various chronic diseases. Fortunately, there are several evidence-based strategies that individuals can employ to lessen their intake of these unhealthy beverages.

Opt for Water

Water is the healthiest and most hydrating beverage choice. Encouraging individuals to drink water instead of sugary drinks can significantly reduce calorie intake and promote overall well-being. Plus, drinking adequate amounts of water every day has a myriad of other health benefits including boosting your cardiovascular and immune health.

Choose Unsweetened Beverages

When selecting beverages, opt for unsweetened options such as unsweetened tea, coffee, or flavored water. These alternatives provide flavor without the added sugars found in sugary drinks. You can also add natural flavors to your water such as herbal leaves, fruits, mint leaves, and other natural options.

Read Labels

Paying attention to food and beverage labels can help individuals identify and avoid products with high sugar content. Look for terms like “sugar-sweetened,” “high-fructose corn syrup,” or “fruit juice concentrate” in the ingredients list. There are many non-sugar beverage alternatives that have a sweet taste from artificial sweeteners, and they are marketed as healthier than those sweetened with sugar, but still be wary of consuming them without proper research.

Limit Portion Sizes

If individuals choose to consume sugary drinks occasionally, encourage them to limit portion sizes. Opting for smaller servings can help reduce overall sugar intake and prevent overconsumption. Buying smaller quantities during grocery shopping can also reduce sugary drinks’ availability in your house and, thus, prevent you from drinking too much of them.

Gradual Reduction

For those accustomed to drinking sugary beverages regularly, gradual reduction may be an effective strategy. Gradually replacing sugary drinks with healthier alternatives over time can help individuals adjust to new habits without feeling deprived. Do not undergo severe diet changes without consulting a healthcare professional.

Substitute with Healthy Alternatives

Encourage individuals to substitute sugary drinks with healthier alternatives such as herbal teas, infused water, or homemade smoothies made with fresh fruits and vegetables.

Limit Availability

Limiting the availability of sugary drinks in the home, workplace, schools, and other environments can help reduce consumption. This can be achieved through policies, regulations, or simply by not purchasing these beverages.

Educational Campaigns

Public health campaigns that raise awareness about the health risks associated with sugary drink consumption can empower individuals to make healthier choices. Providing information about the negative effects of sugary drinks on weight, diabetes, dental health, and overall well-being can motivate behavior change.

Model Healthy Behaviors

Role-modeling healthy beverage choices in the family, community, and workplace can influence others to follow suit. Leading by example and demonstrating the benefits of choosing water or other healthier alternatives can inspire individuals to make similar choices.

Behavioral Support

For individuals struggling to reduce sugary drink consumption, behavioral support such as counseling or support groups may be beneficial. These interventions can help address underlying factors contributing to excessive intake and provide strategies for overcoming barriers to change.

By implementing these strategies, individuals can effectively reduce their consumption of sugary drinks and improve their overall health and well-being. It’s important to recognize that small changes can lead to significant improvements over time, and support from family, friends, and healthcare professionals can be invaluable in achieving success.

Genetic Influences of Unhealthy Food Intake

Aira on May 1, 2024

We all know the feeling. That enticing aroma wafting around the corner of a bakery, the satisfying crunchiness of chips in every munch, and the sugary comfort of a can of cold soda. Unhealthy foods can be a powerful siren song, and indulging occasionally is normal. But what happens when that occasional treat becomes a regular habit?

What Is Considered “Unhealthy Food?”

Unhealthy food intake, often labeled as “junk food” or indicative of a poor diet, encompasses a range of dietary choices that can negatively impact our overall well-being. These food options typically exhibit the following characteristics:

  • High in sodium content: The high sodium levels in processed and convenience foods can lead to water retention, increased blood pressure, and heightened risk of cardiovascular issues when consumed excessively.
  • Lacking essential nutrients: These food selections often lack the necessary vitamins, minerals, and dietary fiber needed to sustain energy levels and support optimal bodily functions. Nutrient deficiency may result in fatigue, digestive issues, and an overall dissatisfaction with one’s diet.

Identifying and minimizing the consumption of such unhealthy foods is essential for cultivating a balanced and nourishing dietary pattern that promotes overall vitality and well-being.

By prioritizing nutrient-dense alternatives and adopting mindful eating practices, individuals can mitigate the negative impacts of excessive junk food consumption and foster a healthier lifestyle.

Unhealthy food intake

How Genetics May Influence Unhealthy Food Intake

Dopamine D2 receptor gene (DRD2) and the nearby ANKK1 can significantly influence our propensity for unhealthy food intake, shedding light on the intricate interplay between genetics and dietary behaviors. 

Research suggests that the presence of the TaqIA polymorphism (SNP rs1800497)  in the ANKK1 gene, may predispose individuals to consume foods that are high in unhealthy carbohydrates or simple sugars, processed or unhealthy meat portions, and deep-fried dishes. 

Moreover, carriers of Taq A1allele (SNP A-allele) may exhibit a higher risk of consuming unhealthy foods such as fried dishes and processed meats, while consuming fewer healthy options. 

This genetic predisposition towards unhealthy food choices is associated with metabolic disturbances, including abnormal glucose and triglyceride levels.

Similarly, investigations into other dopamine receptor polymorphisms, including variants in the DRD2 gene, reveal associations with body mass index (BMI) and hedonic hunger. For example, individuals carrying the Del allele of rs1799732, demonstrate higher BMI and hedonic hunger scores, indicating a heightened susceptibility to overeating and obesity.

Furthermore, studies exploring the neurobiological underpinnings of binge eating disorder (BED) also highlight the role of the genes DRD2 and ANKK1 in modulating responses to positive food stimuli. Variants such as rs1800497 in ANKK1, and rs6277 in DRD2, which reflect enhanced dopamine neurotransmission, were significantly associated with BED and its sub-phenotypes characterized by heightened reward sensitivity and overeating tendencies.

In essence, these genetic variations contribute to an individual’s predisposition towards unhealthy food intake by influencing factors such as taste preferences, hedonic eating behaviors, and metabolic responses.

By understanding these genetic influences, we can tailor interventions and strategies to mitigate the impact of genetic predispositions and promote healthier dietary choices.

Non-Genetic Factors Influencing Unhealthy Food Intake

Our food choices are influenced by a multitude of factors, some of which extend beyond our immediate control. Let’s delve deeper into these influential determinants:

  • Biological determinants: Our innate biological processes, such as hunger, appetite, and taste perceptions, tend to influence our food preferences. Our bodies naturally gravitate towards energy-dense foods, often leading us to succumb to the allure of unhealthy options for quick satisfaction.
  • Economic and physical determinants: Socioeconomic factors, including cost, income level, and access to nutritious foods, significantly shape our dietary patterns. For many individuals, the affordability and convenience of processed foods overshadow the expense and effort required to procure fresh fruits, vegetables, and other healthier options such as lean protein. 
  • Social determinants: Cultural backgrounds, familial traditions, and social networks wield considerable influence over our eating habits. We are inherently social beings, often mirroring the dietary choices of those around us and participating in communal meals that reinforce cultural norms and traditions. Consequently, social gatherings frequently center around food, further cementing its role in our social fabric.
  • Psychological determinants: Our mental and emotional states, including stress, mood fluctuations, and boredom, can trigger cravings for unhealthy foods. During times of distress or emotional turmoil, we may seek solace in sugary or fatty indulgences as a form of temporary comfort or distraction.

Minimizing Unhealthy Food Intake

Curbing unhealthy cravings and opting for healthier choices is a journey worth taking on, and here are some valuable strategies to guide you along the way:

  • Identify your triggers: Understanding the situations that prompt your cravings for junk food is the first step toward gaining control over unhealthy food items. Whether it’s boredom, stress, or simply lack of planning, recognizing these triggers empowers you to develop effective coping mechanisms. Consider activities like taking a brisk walk or keeping wholesome snacks within reach to counteract those impulses.
  • Read food labels: Knowledge is power when it comes to nourishing your body. Take the time to scrutinize food labels, paying close attention to the levels of saturated fat, sugar, and sodium in the products you consume. Armed with this information, you can make more informed choices that align with your wellness goals.
  • Plan your meals: Preparation is key to resisting the allure of fast food and unhealthy options. By proactively planning and preparing balanced meals ahead of time, you ensure that nutritious choices are readily available when hunger strikes. Incorporate whole grains, lean proteins, and an abundance of fruits and vegetables into your meal repertoire for sustained energy and vitality.
  • Don’t demonize treats: Adopting a healthy lifestyle doesn’t mean depriving yourself of the occasional indulgence. Allow yourself to enjoy treats in moderation, savoring each bite mindfully. Consider pairing your indulgence with a nutritious option, such as enjoying a piece of fruit alongside your dessert, to strike a balance between pleasure and nourishment.
  • Make healthy swaps: Transforming your favorite indulgences into healthier alternatives can be both fun and satisfying. Explore creative swaps like replacing regular fries with oven-baked sweet potato fries or indulging in Greek yogurt topped with fresh berries for a creamy, guilt-free delight.

Remember, going on a journey toward healthier eating is about progress, not perfection. Embrace the process of making gradual changes and celebrate your victories along the way. Your journey is unique, and by incorporating your own experiences and insights, you can enrich your path to wellness and inspire others to join you on the quest for a balanced and fulfilling lifestyle.

Water Intake and Genetics

Aira on April 29, 2024

Water is often touted as the elixir of life, and for good reason. It’s an essential component of human existence, playing a critical role in various bodily functions. Despite its importance, many individuals struggle to meet their daily water intake requirements. From maintaining body temperature to facilitating nutrient transport and promoting cognitive function, water is indispensable for overall well-being. In this article, we’ll dive into the intricacies of water intake, exploring how much water individuals should drink daily and offering practical tips for staying hydrated.

Why is Water “The Essence of Life”?

In the human body, water comprises roughly 60% of its composition, playing a fundamental role in various physiological functions. It’s not merely a thirst-quencher; water is essential for processes ranging from detoxification to temperature regulation. Here’s why individuals should consider keeping a water bottle within reach:

Water intake

Daily Water Intake Recommendations

The amount of water a person should drink per day depends on several factors, including age, sex, activity level, and environmental conditions. The National Academy of Science, Engineering, and Medicine recommends an average daily water intake of about 125 ounces for men and about 91 ounces for women either as beverages or as included in other food items. 

However, these recommendations may vary based on life circumstances such as pregnancy, breastfeeding, living in a hot and humid climate, or engaging in physical activity.

How Genetics May Influence Water Intake

Your genetics can have an important role in how much water you need to stay adequately hydrated and how much water you typically consume. Your genes are regulating your whole body, and genetic variants (SNPs) can contribute to person-to-person differences in the typical daily water intake. 

While individual SNP variants can individually be associated with a person’s water intake, another approach for determining a person’s genetic likelihood for a trait is to use a PRS (Polygenic Risk Score), which comes from a combination of multiple SNPs that together play a role in the genetic association. LifeDNA’s high-density SNP signature for the Water Intake trait has been developed from a set of 4994 SNPs that together play a role in daily water intake (note: only 15 top SNPs are displayed on our report).

Some interesting genes and their variants that are contributing to the PRS associated with water intake are highlighted here: 

SLC22A5 (rs17622208) 

The SLC22A5 gene (solute carrier family 22 member 5) encodes for a plasma integral membrane protein that functions both as an organic cation transporter and as a sodium-dependent high-affinity carnitine transporter. Cation transporters such as SLC22A5 have a critical role in the liver, kidney, intestine, and other organs that function in the elimination of many endogenous small organic cations as well as a wide array of drugs and environmental toxins. 

CDK14 (rs696270)

The CDK14 gene (Cyclin-dependent kinase 14) encodes for a serine/threonine-protein kinase that is highly expressed in the brain, pancreas, kidney, heart, testis, and ovary. Its main role is to act as a regulator of the Wnt signaling pathway during cell-cycle G2/M phase. CDK14 may also play a role in meiosis, and neuron differentiation and may indirectly act as a negative regulator of insulin-responsive glucose transport.

GABRA4  (rs2229940)

The GBARA4 gene (gamma-aminobutyric acid type A receptor subunit alpha4) encodes for a gamma-aminobutyric acid (GABA-A) receptor subunit that is highly expressed in the brain. At least 16 distinct subunits of GABA-A receptors have been identified. GABA-A receptors act as ligand-gated chloride channels. GABA, the ligand, is the major inhibitory neurotransmitter in the mammalian brain where it acts at GABA-A receptors, which are ligand-gated chloride channels. Interestingly, a study from 2002 found that the administration of an agonist to GABA-A receptor decreased the water intake in rats. 

Non-Genetic Factors Influencing Water Intake

Aside from genetics, several other factors play a delicate balancing act in determining our daily water needs.

Physiological Factors

Environmental Factors

  • Climate: People who live in hot, humid climates or who are exposed to high temperatures need to drink more fluids to replace fluids lost through sweating.
  • Altitude: People who live or exercise at high altitudes may need to drink more fluids because the air is drier at higher altitudes.
  • Activity level: People who are active or exercise need to drink more fluids to replace fluids lost through sweating.

Behavioral Factors

  • Fluid intake habits: People who are not in the habit of drinking water regularly may be more likely to become dehydrated.
  • Caffeine and alcohol intake: Caffeine and alcohol are diuretics, which means they cause the body to lose fluids. People who consume a lot of caffeine or alcohol may need to drink extra fluids to stay hydrated.
  • Diet: People who eat a lot of fruits and vegetables, which are high in water content, may not need to drink as much water as people who eat a diet that is low in water content.

Sources of Hydration

Water intake can come from both beverages and food. Food items like celery, oranges, strawberries, watermelon, and cucumbers have high water content and can help supplement water intake.

Furthermore, to elevate the experience of drinking water, here are some tips to add flavor and fun to your water intake:

  • Infuse it: Add slices of fruits like lemon, cucumber, or berries to water for a refreshing twist.
  • Go herbal: Fresh mint or ginger can add a subtle flavor boost.
  • Frozen Fruit: Toss in some frozen berries or grapes for a cool and flavorful water experience.
  • Sparkling Water: Unsweetened sparkling water can be a fun alternative to plain water.

However, it is also important to note that drinking too much water can lead to hyponatremia, a condition where the sodium content of the blood becomes dangerously diluted, causing cells to swell.

Signs of Dehydration

The best indicator of whether a person is well hydrated is their body. Signs of dehydration include:

  • Dark yellow or amber-colored urine
  • Headaches or migraines
  • Bad sleep
  • Constipation
  • Dizziness, and feeling light-headed or confused. 

On the other hand, pale yellow or clear urine is a sign of adequate hydration.

Genetic Influences to Tooth Decay

Aira on April 29, 2024

Tooth decay, also known as dental caries, is a prevalent chronic disease affecting individuals worldwide. It is a progressive destruction of tooth structure initiated by a complex interplay between bacterial activity, dietary habits, and host susceptibility. But can genetics influence tooth decay in individuals? Let’s find out.

What Causes Tooth Decay?

The primary etiologic agent of tooth decay is the accumulation of dental plaque, a biofilm composed of various microorganisms, primarily bacteria. Specific bacterial species, such as Streptococcus mutans and Lactobacillus acidophilus, are particularly adept at utilizing dietary sugars to produce organic acids. These acids create an acidic microenvironment that progressively dissolves tooth minerals, initiating enamel demineralization.

Tooth decay

Clinical Manifestations

In its early stages, tooth decay may not present any noticeable symptoms. However, as the demineralization process progresses, individuals may experience:

In advanced stages, cavitations (holes) form within the tooth, potentially leading to pulpitis (inflammation of the dental pulp) and periapical abscesses (infection at the root of the tooth).

How Genetics May Influence Tooth Decay

Recent advancements in genomic research have shed light on the genetic underpinnings of tooth decay.

A groundbreaking GWAS study conducted in 2018 enrolled participants aged from about 3 to 18  years and analyzed data from over 19,000 individuals, including studies on both primary and permanent dentition. Phenotype definitions were meticulously crafted to differentiate between the presence or absence of treated or untreated tooth decay in primary and permanent teeth.

NEDD9

NEDD9, a gene intricately involved in cellular signaling pathways, emerges as a pivotal player in the genetic predisposition to tooth decay, particularly in permanent dentition. Through its modulation of signaling cascades crucial for cell adhesion and migration, NEDD9 may influence the structural integrity of dental tissues, rendering them more vulnerable to acid attacks from oral bacteria metabolism.

Effects from genetic variations, like SNP rs7738851 near the NEDD9 gene, appear to disrupt these pathways, compromising the ability of teeth to withstand microbial colonization and contributing to an increased risk of tooth decay development.

ALLC Gene

In contrast, ALLC, encoding an enzyme involved in purine metabolism, presents a compelling narrative of genetic resilience against primary tooth decay. While the precise mechanisms remain elusive, ALLC’s involvement in metabolic pathways suggests a potential link between systemic metabolism and oral health.

Genetic variations within the ALLC gene (e.g. rs1594318) may confer protection against tooth decay development in primary dentition, potentially by modulating oral microbial composition or influencing the structural integrity of dental tissues.

GRIN2B Gene

In another study on children exhibiting a high DMFT (Decayed, Missing, and Filled Teeth) index, significant associations between pediatric tooth decay and SNPs within the GRIN2B gene, notably rs4764039-C, were unveiled. These findings suggest a potential involvement of GRIN2B in the development of tooth decay. Furthermore, behavioral factors such as irregular tooth brushing and irregular dental visits were identified as significant contributors to susceptibility. This research underscores the complex interplay between genetic predispositions and environmental factors in pediatric tooth decay, pointing towards the potential for targeted interventions tailored to individual risk profiles.

Non-Genetic Factors Influencing Tooth Decay

Several factors contribute to the susceptibility of an individual to tooth decay, a multifactorial process influenced by various elements:

  • Dietary Habits: The frequency of consuming sugary foods and beverages is a pivotal factor. Regular intake of such items provides ample opportunity for bacteria to metabolize sugars into acids, which attack tooth enamel, leading to demineralization and eventual decay.
  • Oral Hygiene Practices: Inadequate oral hygiene, such as irregular brushing and flossing, allows plaque—a sticky film of bacteria—to accumulate on teeth. Persistent plaque provides a breeding ground for bacteria, facilitating acid production and accelerating the demineralization process.
  • Saliva Composition and Flow Rate: Saliva plays a crucial role in maintaining oral wellness by neutralizing acids, remineralizing teeth, and washing away food particles and bacteria. However, variations in saliva composition and flow rate can affect its protective properties. Reduced salivary flow, for instance, hampers the body’s natural buffering capacity, making teeth more vulnerable to acid attacks and impairing remineralization.
  • Age and Life Stage: Tooth decay risk varies across different life stages. Children and older adults, for instance, may be more susceptible due to factors such as dietary habits, oral hygiene practices, and changes in saliva production. Additionally, lifestyle factors and health conditions that emerge with age can further influence susceptibility to decay.

Treatment Options

The management of tooth decay is contingent upon the severity of the condition, with various interventions tailored to address specific stages of decay:

  • Early-stage Lesions: At the onset of decay, early-stage lesions may be reversible with appropriate interventions focused on remineralization. This often involves using fluoride toothpaste, which helps remineralize enamel and arrest the progression of decay. Additionally, professional topical fluoride applications administered by a dentist can enhance remineralization and strengthen tooth enamel, providing added protection against further demineralization.
  • Cavitated Lesions: When decay advances to the point of cavitation, where a cavity or hole forms in the tooth structure, restorative treatments become necessary to repair the damage and restore tooth function. Common restorative options include dental fillings, which involve removing the decayed portion of the tooth and filling the cavity with a suitable material such as composite resin or amalgam. In cases of more extensive damage or structural compromise, dental crowns or onlays may be recommended to provide additional support and coverage.
  • Pulp Necrosis: In severe cases where decay penetrates deep into the tooth, reaching the dental pulp—the soft tissue containing nerves and blood vessels—pulp necrosis, or the death of the dental pulp, may occur. To salvage the tooth and alleviate pain, root canal therapy is often performed. This procedure involves removing the infected or necrotic pulp tissue, disinfecting the root canals, and sealing them to prevent further infection. Following root canal treatment, the tooth is typically restored with a filling or crown to strengthen and protect it from future damage.
  • Extensive Tooth Destruction: In situations where tooth decay has caused extensive damage beyond salvageable repair, or if untreatable infection compromises the surrounding tissues, tooth extraction may be the only viable option. Although extraction is typically considered a last resort, it may be necessary to prevent further complications and preserve overall oral health.

The genetics of food liking, including sardines, is a complex and multifaceted area of research. Twin studies have shown that food preferences, including liking, are moderately heritable traits, with around 50% of their variance in children being explained by genetic factors plus mostly shared environmental effects. In adults, while heritability remains stable, the shared environmental component disappears in favor of the non-shared one (e.g. personal experience).

In a large-scale GWAS study of food liking in 2022, researchers identified 1,401 significant food-liking associations which showed substantial agreement in the direction of effects with 11 independent cohorts. The study also used genetic correlations combined with genomic structural equation modeling to create a multi-level map of the relationships between different food preferences, highlighting three main domains that they define as “Highly palatable”; including desserts, meat, and savory foods, “Low caloric”; including vegetables, fruit, and whole grains, and “Acquired” foods including unsweetened coffee, alcohol, cheese, and strong-tasting vegetables.

Utilizing data from this study, LifeDNA analyzes genetic variants in several genetic locations to provide personalized insights into sardines liking. These locations include genes such as  HNF4GP1, MIR5007, LINC02326, RNU11-5P, and FTO.

Genetic variants are associated with different food-liking dimensions, and they potentially influence food liking through distinct mechanisms involving neural development, energy metabolism, and reward processing.

These findings provide insights into the genetic and neural basis of food preference and choice, which are critical factors in designing better, more targeted dietary interventions and more acceptable nutritious foods.

Non-Genetic Factors Influencing Sardines Liking

Aside from genetics, several other factors influence sardines liking. This may include an interplay between personal preferences, societal influences, and sensory experiences in the realm of culinary taste.

Why Do Humans Feel Guilt? Understanding the Genetics of Guilt

Aira on April 25, 2024

Guilt is a complex emotional experience that arises when a person believes they have done something morally, legally, or socially wrong. It involves a profound sense of remorse and the desire to make amends or punish oneself. The sensation of guilt can vary significantly from person to person and situation to situation, but there are common elements.

What Can Guilt Do To a Person?

Physically, guilt can manifest through symptoms such as a knot in the stomach, tightness in the chest, an increased heart rate, or a feeling of heaviness. These sensations are often accompanied by sweating, shaking, or a sudden drop in energy levels, indicating the body’s acute stress response. 

Psychologically, guilt can lead to a preoccupation with the transgression, difficulty concentrating on other tasks, and pervasive thoughts about what could have been different.

Emotionally, guilt is associated with feelings of sadness, regret, and despair. A person might feel unworthy or inadequate, compounded by a sense of isolation as they perceive that others would judge them harshly if they knew the truth. It can lead to self-critical thoughts and a distorted self-image, where the individual sees themselves as a failure or inherently bad.

Furthermore, guilt can also impact behavior. It might cause someone to avoid others, withdraw from activities they enjoy, or engage in overcompensatory behaviors to alleviate the guilt. Social interactions can become strained, especially if the guilty person fears their actions have hurt someone else, leading to awkwardness or hostility in relationships.

Overall, guilt is an emotional state that involves a significant amount of self-inflicted emotional pain and anxiety, reflecting the internal conflict between one’s actions and one’s values or moral standards.

Humans Feel Guilt

What is Unhealthy Guilt?

Unhealthy guilt is characterized by a disproportionate sense of responsibility or remorse for actions that did not cause harm. It is when the perceived wrongdoing is not reality-based. 

This type of guilt is excessive and unwarranted. It does not correspond to actual moral or social transgressions. Unhealthy guilt can be damaging, often trapping individuals in a cycle of self-blame and regret over actions that are normal or, in many cases, unavoidable.

One common manifestation of unhealthy guilt is when individuals feel guilty about actions they have little control over. Or when they assume responsibility for situations influenced by external factors beyond their control. For example, a person might feel guilty for being involved in an accident that was not their fault or for being unable to prevent a friend’s distress despite having no reasonable means to influence the outcome.

Unhealthy guilt can also arise from rigid, perfectionistic expectations of oneself. It can be linked to upbringing or past experiences where the individual was frequently made to feel accountable for things unfairly. This guilt is persistent and does not ease even after the individual has tried to make amends or has been forgiven by others. It can lead to a chronic state of feeling unworthy or inadequate, significantly impacting an individual’s self-esteem and mental health.

Perfectionism

Perfectionism is a personality trait characterized by a person’s striving for flawlessness and setting excessively high-performance standards, accompanied by overly critical self-evaluations and concerns regarding others’ evaluations. 

In 1978 D.E Hamacheck wrote a paper distinguishing between two types of perfectionists: neurotic perfectionists and normal perfectionists. 

  • Neurotic Perfectionists: They set unrealistically high standards for themselves and are overly critical of their performance. Neurotic perfectionists are prone to experiencing negative emotions such as shame and guilt because they often focus on their failures and perceive themselves as never being good enough. They are unable to feel genuine pride in their achievements because their self-imposed standards are impossibly high, leading to a perpetual sense of inadequacy.
  • Normal Perfectionists: While they also set high standards, they have a more balanced and rational approach to achieving these goals. Normal perfectionists can experience pride in their accomplishments and are not overwhelmed by shame and guilt. This is because they accept their limitations and see their efforts as worthwhile, even if perfection is not achieved. Their self-evaluation is more forgiving, which allows for a positive emotional state following achievements.

A 2007 behavioral study was able to build on this concept. It involved 121 undergraduates categorized into healthy perfectionists (high perfectionistic strivings, low concerns), unhealthy perfectionists (high strivings, high concerns), and non-perfectionists (low strivings). The findings revealed that healthy perfectionists feel more pride and less shame and guilt compared to both unhealthy perfectionists and non-perfectionists. They also show less tendency towards shame and guilt, but have a higher tendency to experience pride than non-perfectionists.

Genetics of Guilty Feelings

The guilt experience is influenced by genetic and environmental factors, with genetics playing a significant role in determining one’s propensity for feeling guilty. Research in the field of behavioral genetics has indicated that certain personality traits associated with guilt, such as empathy, anxiety, and neuroticism, also have a genetic basis.

BDNF

A 2015 study examined how early trauma and specific genetic variants—namely, the brain-derived neurotrophic factor (BDNF) Val66Met (rs6265), and the serotonin transporter gene promoter (5-HTTLPR)—influence guilt and other associated emotions. 

The findings revealed that the intensity of experienced trauma correlates positively with guilt-proneness but only in adolescents who possess the low-expressing Met allele of the BDNF Val66Met polymorphism. This gene-environment interaction suggests significant implications for understanding how guilt develops and potentially contributes to psychopathology in youths.

OXTR

The OXTR gene encodes for the oxytocin receptor, a protein that binds oxytocin, a hormone significantly involved in social behavior and reproduction. Oxytocin, often referred to as the “love hormone,” plays a crucial role in various social behaviors, including mother-infant bonding, romantic attachment, and social recognition.

A 2014 study explored the genetic bases of human reconciliation behaviors, specifically self-punishment, in the context of unfair actions. Findings revealed that individuals with GA or GG genotypes of the rs53576 variant were more likely to self-punish compared to those with the AA genotype, indicating that the OXTR gene variation is linked to reconciliation tendencies, independent of feelings like guilt or shame.

ELAVL2

The ELAVL2 gene, also known as Hu-antigen B (HuB), is part of the ELAV-like family of proteins. This family includes several RNA-binding proteins in various cellular processes that regulate mRNA stability and translation. The ELAV-like proteins are key players in the post-transcriptional gene expression regulation, affecting cell proliferation, differentiation, and survival. A 2018 study found out that genetic variations in this gene (rs10119773) can influence how prone you are to feelings of guilt.

GRIA3 and GRIK1 Glutamate Receptor Genes

The GRIA3 gene encodes for Glutamate Ionotropic Receptor AMPA Type Subunit 3, a part of the AMPA receptor complex. AMPA receptors are critical components of synaptic transmission in the brain, facilitating fast synaptic transmission in the central nervous system.  A 2012 study investigated the genetic underpinnings of individual depressive symptoms in 241 Korean patients diagnosed with major depression according to DSM-IV-TR criteria. Results revealed that the TT variant of rs557762 SNP of the GRIA3 gene was correlated with increased feelings of guilt among female patients.

Interestingly, the 2018 study found a SNP (rs681875)  in another brain expressed glutamate receptor gene, GRIK1, to be associated with increased feelings of guilt. GRIK1 encodes for glutamate ionotropic receptor kainate type subunit 1. This association was confirmed by a 2021 study including over 450,000 participants, both female and male, which found several guilty feeling  SNPs in the GRIK1 gene as well. 

Non-Genetic Reasons for Feeling Guilty

While genetics play a role in the propensity to feel guilty, non-genetic factors are equally influential. These include cultural, societal, and personal experiences that shape an individual’s understanding of guilt and their reactions to it.

Cultural Influences: Different cultures have varying norms and values, which can dictate when and why guilt is experienced. For instance, collectivist societies, which emphasize the group’s welfare over the individual, might induce guilt more frequently in contexts involving familial or communal obligations. Conversely, in individualistic societies, guilt might be more commonly linked to personal failings or breaches of personal ethics.

Societal and Familial Expectations: Expectations imposed by society or family can create a fertile ground for guilt. For instance, parents who set particularly high standards can inadvertently foster feelings of guilt in their children for not meeting these expectations. Similarly, societal pressures related to roles, such as those about gender or profession, can also trigger guilt.

Personal Experiences and Values: Personal history plays a critical role in developing guilt. Traumatic events, especially those where the individual feels they could have acted differently, often lead to long-lasting feelings of guilt. Additionally, personal values and morals, developed over time and influenced by cultural and individual experiences, define what an individual considers right or wrong, thus influencing guilt responses.

Psychological Factors: Mental health conditions can affect how guilt is experienced. For example, individuals with depression or anxiety are more likely to interpret situations in a way that induces guilt, regardless of their actual culpability. This is often due to distorted thinking patterns characteristic of these psychological conditions.

Overall, non-genetic factors are pivotal in shaping how guilt is experienced and managed. They provide the context in which genetic predispositions are expressed and are essential considerations in psychological counseling and therapy.

Is Feeling Guilty About Eating a Disorder?

Feeling guilty about eating can be a symptom of an eating disorder, particularly if the guilt is excessive, persistent, and specifically related to eating habits. This condition is often associated with disorders such as anorexia nervosa, bulimia nervosa, and binge eating disorder. 

In the context of these disorders, guilt about eating is not just a casual regret but a profound and distressing experience that significantly impacts the individual’s mental health and dietary behaviors.

In anorexia nervosa, individuals may feel intense guilt after consuming what they perceive as too much food or food that is off-limits according to their dietary rules. This guilt can contribute to further food restriction and starvation. 

In bulimia nervosa, episodes of binge eating are followed by feelings of extreme guilt, which then lead to compensatory behaviors such as vomiting, excessive exercise, or the use of laxatives. Similarly, in binge eating disorder, individuals often feel profound guilt and shame following a binge, which can exacerbate the cycle of emotional eating.

Guilt related to eating can also occur outside of these clinical disorders in what might be considered disordered eating behaviors. Examples include feeling guilty after eating dessert, eating when not physically hungry, or eating certain types of food deemed unhealthy. This guilt can stem from societal pressures, personal body image issues, or from internalizing idealized health standards.

Is Optimism the Same as Positivity?

While optimism and positivity share a common thread of positive thinking, they encompass distinct psychological constructs. Scientifically, optimism is characterized by a positive expectation regarding future outcomes, emphasizing a hopeful outlook despite challenges. 

It’s grounded in a cognitive perspective that anticipates favorable results. Positivity, on the other hand, is a broader concept encompassing a general inclination towards positive emotions, attitudes, and experiences in the present. It involves maintaining an affirmative mindset without necessarily focusing on future outcomes.

Research in positive psychology underscores these differences. Optimism is often regarded as a specific cognitive trait, measurable through various psychological assessments, reflecting an individual’s expectation for positive outcomes in diverse life situations. Positivity, however, extends beyond cognitive processes to include a broader spectrum of emotional experiences and expressions.

While both optimism and positivity contribute to well-being, optimism specifically pertains to future expectations, whereas positivity encompasses a broader embrace of positive emotions in the present. Understanding these distinctions enhances our comprehension of the nuanced ways in which positive thinking manifests in our thoughts, emotions, and overall mental outlook.

How to Control Unhealthy Guilty Feelings

Controlling guilty feelings involves understanding their origins and implementing strategies to manage them effectively. 

Whether guilt serves a functional purpose by encouraging corrective actions or becomes a source of chronic stress, managing it can lead to better psychological health and improved relationships. Here are several strategies:

Cognitive-Behavioral Techniques: One practical approach is cognitive-behavioral therapy (CBT), which helps individuals recognize and alter distorted thinking patterns that cause undue guilt. For example, restructuring thoughts to see situations more realistically can diminish feelings of guilt.

Mindfulness and Meditation: These practices can help individuals become more aware of their emotions and thoughts without becoming overwhelmed by them. Mindfulness teaches acceptance, allowing one to acknowledge guilt without letting it dictate their actions or self-worth.

Communication and Apologies: If guilt stems from a genuine mistake that affects others, addressing it directly through communication or an apology can alleviate the feeling. This not only helps resolve the underlying issue but also reclaims a sense of agency.

Set Realistic Expectations: Often, guilt arises from unrealistically high expectations of oneself. Reevaluating these expectations to ensure they are achievable and forgiving oneself for mistakes can significantly reduce feelings of guilt.

Professional Help: Persistent or severe guilt, especially when linked to depression, anxiety, or past trauma, may require professional counseling. Psychologists and therapists can provide tailored strategies for coping with guilt, including exploring underlying issues through psychotherapy.

Healthy Lifestyle Choices: Regular exercise, sufficient sleep, and a balanced diet can improve one’s overall mental health, making it easier to handle emotions like guilt.

By employing these strategies, individuals can manage their feelings of guilt more effectively, leading to healthier emotional processing and interactions with others.

Demystifying The Complex Genetics of Mood Swings

Aira on April 25, 2024

Disclaimer: This article is meant for information purposes only. LifeDNA does not offer clinical diagnoses for any conditions discussed herein or otherwise.

What Are Mood Swings?

Mood swings or Mood Instability refer to rapid and often intense changes in one’s emotional state. This phenomenon can see an individual fluctuating between happiness, sadness, irritability, or anger with little to no apparent reason. Unlike the regular ebb and flow of emotions experienced by most people, mood swings can be severe, sudden, and seemingly unprovoked. They can impact an individual’s ability to function in daily life, affecting relationships, work performance, and overall well-being. 

Mood swings can range from minor fluctuations in temperament to significant shifts that might indicate underlying psychological or medical issues. Understanding mood swings involves recognizing their frequency, intensity, and impact on life and identifying patterns that may suggest specific triggers or underlying causes.

Mood swings

What Causes Mood Swings?

A variety of factors, both psychological and physiological, can cause mood swings. Psychological causes include stress, anxiety, and mental health disorders such as bipolar disorder, depression, and personality disorders. 

Physiologically, hormonal imbalances play a significant role, especially those related to menstrual cycles, pregnancy, and menopause in women, as well as thyroid disorders and other endocrine system disturbances. Lifestyle factors such as diet, exercise, sleep patterns, and substance use also significantly influence mood regulation. 

Additionally, certain medications and medical conditions can lead to mood swings as side effects or symptoms. It is important to note that the specific causes of mood swings can vary greatly from person to person, and a multifaceted approach considering both psychological and physiological factors is often necessary to understand and address them effectively.

Read our full analysis of the Genetics of Depression

Genetics of Mood Swings

Several genes have been shown to have varying influences on mood swings. A few of them are discussed below:

DRD2

The DRD2 gene is associated with the dopamine receptor D2, a component of the dopamine system in the brain. Dopamine is a neurotransmitter that plays a significant role in regulating mood, motivation, reward, and the pleasure centers of the brain. Variations in the DRD2 gene have been studied for their potential impact on mood swings and other psychiatric conditions because they influence dopamine signaling. One particular variant  (rs12420205) has been significantly associated with mood swings.  

SORCS3

The SORCS3 gene (Sortilin-Related VPS10 Domain Containing Receptor 3) is increasingly recognized in neuroscience and psychiatric research for its potential role in mood regulation. The SORCS3 gene encodes a protein that is part of the VPS10 domain receptor family, which is involved in neuronal development and the regulation of neurotrophic factors. These receptors play a critical role in the central nervous system, influencing synaptic plasticity, neurotransmitter signaling, and neuron survival, all essential for proper brain function and mental health.

Research has indicated that genetic variations (e.g. rs11599236) in the SORCS3 gene may be linked to susceptibility to mood instability. 

DCC

DCC netrin 1 receptor gene (DCC), is fascinating because this very large gene is situated in a region where no other protein-coding genes are found within a 500 kb radius. DCC plays a crucial role in the development of the nervous system, notably affecting the organization and functionality of mesocorticolimbic dopamine systems, which are vital for emotional regulation and mood.

According to a 2017 genome-wide association study (GWAS), variations in the DCC gene (like rs8084280, rs34160346 & rs11877496) may increase susceptibility to mood instability, mood disorders, and related psychological conditions, making it a gene of significant interest in the study of these disorders.

PLCL1

The PLCL1 gene, which stands for Phospholipase C Like 1, has been investigated in various psychological and neurological conditions. Earlier GWASs have connected this gene with schizophrenia and bipolar disorder. Genetic variations in this gene, like rs9857592 and rs12477961, have been found to influence mood stability.

NEGR1

The NEGR1 (Neuronal Growth Regulator 1) gene is involved in neuronal growth and brain development. It encodes a protein that is part of the immunoglobulin superfamily and is located on the cell surface of neurons. NEGR1 plays a significant role in neurodevelopment and is thought to be involved in cell adhesion processes critical for forming and maintaining neuronal networks.

Genetic variations in this gene, such as rs2000228, have been shown to influence mood instability.

Non-Genetic Factors Influencing Mood Swings

Non-genetic factors that influence mood swings encompass various environmental, psychological, and physiological elements. These factors can interact with each other and with genetic predispositions to affect mood stability. 

Understanding these can be crucial for managing mood swings and developing appropriate intervention strategies. Here’s a look at some key non-genetic factors:

1. Psychological Stress

High stress levels from personal, professional, or social challenges can significantly contribute to mood swings. Stressful life events, such as the loss of a loved one, financial problems, or relationship issues, can trigger emotional instability.

2. Sleep Patterns

Poor sleep quality or sleep disorders like insomnia can profoundly impact mood regulation. Lack of sleep can exacerbate irritability, anxiety, and depression, leading to more pronounced mood swings.

3. Diet and Nutrition

Diet plays a crucial role in mood regulation. Nutritional deficiencies (e.g., low omega-3 fatty acids, vitamin D) can contribute to mood instability. Conversely, a balanced diet can support a stable mood.

4. Substance Use

The use of alcohol, drugs, and even caffeine can influence mood swings. Substances that affect the central nervous system can lead to temporary mood elevation followed by a crash, contributing to mood instability.

5. Hormonal Changes

Hormones have a significant impact on mood. Fluctuations related to menstrual cycles, pregnancy, thyroid disorders, or menopause can cause mood swings. For example, conditions like Premenstrual Syndrome (PMS) or Premenstrual Dysphoric Disorder (PMDD) are directly linked to hormonal changes and mood swings.

6. Physical Health Conditions

Chronic physical health conditions, such as chronic pain, diabetes, heart disease, or neurological disorders, can contribute to depression and anxiety, leading to mood swings.

7. Medications

Some medications can affect mood as a side effect. For example, steroids are known to cause mood swings in some individuals. Always consult healthcare providers about potential mood-related side effects of any medication.

8. Environmental Factors

Changes in season or weather (e.g., Seasonal Affective Disorder), exposure to toxins, and other environmental factors can influence mood and emotional well-being.

9. Social Support and Relationships

The quality of one’s social relationships and the degree of social support can influence emotional stability. Isolation or conflict-ridden relationships can lead to stress and mood swings.

10. Psychological Disorders

While not purely non-genetic (given the genetic component of many psychological disorders), conditions like bipolar disorder, depression, and anxiety disorders are characterized by significant mood swings. Therapy and medication are often required to manage these conditions.

Recognizing and addressing these non-genetic factors can be essential for individuals experiencing mood swings. Lifestyle adjustments, stress management techniques, therapy, and, in some cases, medication, can help manage these influences and support mood stability.

When Do Mood Swings Start In Pregnancy?

Around one in eight women experience depression or anxiety during pregnancy. These emotional fluctuations are primarily attributed to hormonal changes, particularly increases in estrogen and progesterone, which can affect neurotransmitter levels in the brain, impacting mood regulation. 

Additionally, the physical discomforts of pregnancy, concerns about childbirth, and the impending responsibilities of parenting can contribute to stress and anxiety, further exacerbating mood swings. Each woman’s experience is unique, but common triggers include fatigue, physical changes, and the emotional stress of preparing for a new life stage. Understanding that these mood swings are a normal part of pregnancy for many women can help manage expectations and reduce stress.

How Do You Control Mood Swings During Periods?

The menstrual cycle is a monthly process that the female body goes through to prepare for the possibility of pregnancy, involving the release of an egg for fertilization (ovulation) and the shedding of the uterine lining if pregnancy doesn’t occur. The term “periods” refers specifically to the latter part.

Controlling mood swings during periods involves a holistic approach focusing on lifestyle, dietary, and stress-management strategies. Regular exercise can help stabilize mood, as physical activity increases endorphins, improving overall emotional well-being. 

A balanced diet that limits caffeine, sugar, and alcohol while being rich in fruits, vegetables, and whole grains can also support mood stability. Ensuring adequate sleep and practicing relaxation techniques such as mindfulness or meditation can further aid in managing stress and emotional fluctuations. 

How Do You Control Mood Swings During Ovulation?

Ovulation is the phase in a woman’s menstrual cycle when a mature egg is released from the ovary into the fallopian tube, making it available for fertilization. Hormonal fluctuations, involving estrogen, progesterone, and luteinizing hormone, have been attributed to mood swings.

Controlling mood swings during ovulation involves a combination of lifestyle adjustments, stress management techniques, and sometimes medical intervention. Regular exercise, a balanced diet rich in nutrients, and sufficient sleep can significantly improve emotional regulation. Stress-reduction techniques such as meditation, yoga, and deep-breathing exercises can also help. 

Tracking ovulation and being aware of the timing can prepare individuals to anticipate and manage mood swings more effectively. For some, over-the-counter pain relievers or birth control pills (under a doctor’s guidance) can help balance hormones and mitigate mood swings. It’s crucial to prioritize self-care and, if mood swings are severe or persist, to consult with a healthcare provider for personalized advice and treatment options.

How Do You Deal With Prednisone Mood Swings?

Prednisone is a type of corticosteroid medication that was commonly prescribed to reduce inflammation and suppress the immune system. It’s used to treat a variety of conditions, including asthma, allergic reactions, skin diseases, arthritis, lupus, multiple sclerosis, and certain types of cancer. While effective, it can also have a range of side effects, such as increased susceptibility to infection, mood swings, weight gain, and high blood pressure, especially with long-term use.

Dealing with prednisone-induced mood swings requires understanding that these are a side effect of the medication and may not always be fully preventable. Communicating openly with healthcare providers about side effects is crucial, as they may adjust the dose or suggest alternatives. Implementing strategies to manage stress, such as regular physical activity, relaxation techniques, and ensuring a supportive environment, can mitigate some emotional instability. 

Takeaway

Individuals with mood swings or mood instability can fluctuate between happiness, sadness, irritability, or anger with little to no apparent reason. Mood swings can be influenced by both genetic and non-genetic factors. Maintaining a healthy lifestyle, with a balanced diet and adequate sleep, supports overall well-being, potentially reducing the severity of mood swings. 

It’s also beneficial to inform friends and family about potential mood changes to foster understanding and support. If mood swings become severe or unmanageable, seeking professional medical advice is essential for adjusting treatment plans and exploring additional interventions.

Does Your Genetics Influence Your Social Life?

Aira on April 25, 2024

What is Social Rejection?

Social rejection occurs when an individual is deliberately excluded from a social relationship or social interaction. The experience can range from being ignored in a conversation and not being invited to social gatherings to more severe forms such as bullying, ostracization, or discrimination. 

This phenomenon is not limited to personal relationships but can also occur in a professional setting. Psychological research suggests that social rejection can affect a person’s emotional, cognitive, and physical health. 

The brain processes social pain like physical pain, indicating the profound impact of rejection on human well-being. Social rejection can lead to feelings of loneliness, decreased self-esteem, anxiety, and depression. Understanding the mechanics and effects of social rejection is crucial for developing coping mechanisms and promoting more inclusive social environments.

The Cyberball Experiment

The Cyberball experiment, developed by Kip Williams and colleagues, uses a virtual ball-tossing game to study social exclusion. Participants believe they are playing an online game with others, but the other players are computer-generated. Eventually, the computer stops throwing the ball to the participant, simulating social rejection. 

This experiment has consistently shown that even minimal social exclusion can lead to increased feelings of distress, low mood, and a fundamental need to belong, underscoring the deep impact of social rejection on emotional well-being. Several behavioral and genetic studies on social rejection use this exercise.

Social rejection

What Causes Social Rejection?

A complex interplay of individual behaviors, societal norms, and group dynamics causes social rejection. At the individual level, personal traits such as aggression, shyness, or non-conformity can trigger rejection. 

Societal norms and stereotypes play a significant role, as deviations from these expectations can lead to exclusion. In group settings, dynamics such as conformity pressure, competition, and the need for cohesion can result in the rejection of members perceived as different or threatening to the group’s identity. 

Additionally, structural factors like racism, sexism, and other forms of discrimination contribute to systemic social rejection. Understanding these causes is crucial for addressing and mitigating social rejection in various contexts.

Genetics of Social Rejection

OPMR1 

The OPRM1 gene is responsible for encoding the μ-opioid receptor, a type of protein found on the surface of cells in the brain and nervous system. This receptor plays a critical role in the body’s response to opioids—substances that include both powerful pain relievers, such as morphine and codeine, and illegal drugs like heroin. Opioid receptors are involved in pain modulation, mood regulation, and the reward system, influencing feelings of pleasure and pain relief.

In a 2009 study, 122 participants reported their sensitivity to social rejection, with a subset of 31 undergoing fMRI scans during a simulated social rejection scenario in an online game. The findings revealed that individuals with the G allele of the A118G polymorphism (rs1799971) were more sensitive to social rejection, showing increased activity in brain areas (the dorsal anterior cingulate cortex and anterior insula) known for processing both social and physical pain. 

The study found that this activity in the dorsal anterior cingulate cortex mediated the relationship between the A118G polymorphism and sensitivity to rejection. These results suggest a significant role for the μ-opioid receptor in the experience of social pain, paralleling its involvement in physical pain, and highlight the A118G polymorphism’s impact on susceptibility to feeling social rejection.

MAOA

The MAOA gene (Monoamine Oxidase A) is crucial for encoding the enzyme monoamine oxidase A. This enzyme plays a significant role in the metabolic breakdown of neurotransmitters in the brain, such as serotonin, norepinephrine, and dopamine. These neurotransmitters are essential for regulating mood, emotion, and various other behaviors. By breaking down these chemicals, MAOA helps maintain their balance within the nervous system, influencing emotional regulation and behavioral expression.

In a fascinating  2010 study, researchers found an interesting link between MAOA gene expression, age, and response to social rejection. Instead of SNPs, the researchers investigated several variable number tandem repeats (VNTRs). This polymorphism affects the gene’s expression levels, with 3.5 or 4 repeats leading to higher expression (MAOA-high) and 3 or 5 repeats resulting in lower expression (MAOA-low). Adults carrying the MAOA-low activity variant of the gene showed a slightly more significant response to rejection words than those with the MAOA-high activity variant, indicating a heightened sensitivity to social rejection cues in the adult/low group. Adolescents with the MAOA-high activity gene variant responded more strongly to rejection words than their MAOA-low activity counterparts. It suggests a greater reactivity to social rejection in the adolescent/high group.

OXTR

The OXTR gene encodes the oxytocin receptor,  a critical component of the oxytocin signaling pathway in the body. Oxytocin is often known as the “love hormone” or “social bonding hormone” because of its significant role in facilitating social interactions, maternal behaviors, pair bonding, and trust. The oxytocin receptor allows cells in the brain and other parts of the body to respond to the oxytocin hormone, mediating its effects on behavior and physiology.

In a 2015 study, findings suggest that while individuals harboring the OXTR G-allele of SNP rs53576 exhibit more prosocial behaviors, making individuals more cooperative and empathetic, it also increases their vulnerability to the negative impacts of social stressors, such as ostracism or rejection.

Further, a 2016 study also noted that individuals carrying the same G-allele are predisposed to exhibit positive social qualities, which generally leads to more favorable outcomes when encountering social stressors. However, these people may simultaneously exhibit greater social sensitivity. In addition, the study also found that those with the A-allele might find it challenging to engage in or maintain various group affiliations due to fear of rejection or negative social experiences.

Non-genetic Factors Affecting Social Rejection

Several non-genetic factors influence social rejection, encompassing socio-economic status, cultural background, personality traits, and interpersonal skills. Socio-economic disparities can create divisions within social groups, leading to exclusion. 

Cultural differences can also be a barrier to social acceptance, as individuals from minority cultures may face challenges in integrating with the dominant culture. Personality traits such as shyness, introversion, or aggression can affect an individual’s ability to connect with others and increase the risk of being socially rejected. 

Additionally, poor interpersonal skills, including lack of empathy, difficulty in communication, and inability to read social cues, can lead to misunderstandings and social rejection. 

Addressing these factors through education, awareness, and personal development can help reduce instances of social rejection.

How to Deal with Social Rejection

Dealing with social rejection involves a multifaceted approach focusing on self-care, perspective-shifting, and building resilience. Initially, acknowledging and processing the emotions associated with rejection is vital. It may include expressing feelings through writing, art, or conversation. 

Engaging in activities that bolster self-esteem and foster a positive self-image can also mitigate the impact of rejection. Developing a broader perspective helps us understand that rejection is not always personal and can be due to various external factors. 

Cultivating a strong friends and family support network can provide emotional comfort and reassurance. 

Additionally, practicing resilience by facing fears of rejection and learning from experiences can enhance personal growth and emotional strength. These strategies can help individuals cope with social rejection and contribute to a more fulfilling social life.

It is also important to note that not everybody prefers a thriving social life. Having a few meaningful relationships in your life can go a long way. While enjoying activities by yourself, like painting, cooking, or gardening, are often shown negatively in pop culture, it could also be signs of a content and independent personality.

Can Your Job-Related Exhaustion Be Genetic?

Aira on April 17, 2024

Overview

In the relentless pursuit of career success, individuals often find themselves grappling with the overwhelming burden of job-related exhaustion. This pervasive phenomenon not only affects personal well-being but also poses significant challenges to workplace productivity and satisfaction. 

While environmental factors such as workload and organizational culture play pivotal roles, recent scientific inquiries suggest a genetic predisposition to experiencing job-related exhaustion. Understanding the interplay between genetic makeup and occupational stress is crucial for devising effective interventions and support systems.

Job-Related Exhaustion

What is Exhaustion?

Exhaustion, in psychological terms, refers to a state of physical and emotional depletion resulting from prolonged periods of stress or exertion. It encompasses feelings of fatigue, disengagement, and reduced efficacy, manifesting as burnout in occupational contexts. 

While environmental stressors undoubtedly contribute to this condition, emerging research sheds light on the genetic underpinnings that may predispose certain individuals to heightened vulnerability.

Can Exhaustion Be Purely Job-Related?

Exhaustion, particularly when it comes to job-related burnout, is a multifaceted phenomenon influenced by various factors. While the workplace undoubtedly plays a significant role, it’s essential to recognize that exhaustion can stem from a combination of job-related stressors and personal predispositions.

Research in occupational psychology consistently demonstrates the impact of workplace factors on exhaustion levels. High work demands, lack of autonomy, and poor organizational support are commonly cited contributors to job-related burnout. Studies have shown that individuals in demanding professions such as healthcare, education, and customer service are particularly susceptible.

However, it’s crucial to acknowledge that exhaustion isn’t solely determined by external job-related factors. Genetic predispositions also play a role in an individual’s susceptibility to burnout. Genetic variations can influence an individual’s stress response mechanisms, resilience levels, and susceptibility to mental health disorders—all of which contribute to their vulnerability to job-related exhaustion. 

Understanding this interplay between genetics and environmental stressors is vital for developing targeted interventions and support systems to mitigate burnout in the workplace. Recognizing this complexity is crucial for addressing and preventing job-related exhaustion effectively.

What are the Factors That Can Contribute to Job-Related Exhaustion?

Genetic Factors

A 2017 study delving into the world of shift work has uncovered intriguing findings regarding genetic factors associated with job-related exhaustion. Scientists aimed to understand why some shift workers experience fatigue and burnout while others adapt more easily to irregular schedules.

Through a genome-wide association study (GWAS) involving 176 shift workers, researchers identified a significant genetic signal linked to job-related exhaustion. This signal, observed at a specific genetic variant called rs12506228, is located near the gene responsible for encoding the melatonin receptor 1A (MTNR1A).

Further investigation revealed that individuals carrying the risk allele (A) of rs12506228 tended to have reduced expression levels of MTNR1A in brain tissue. This suggests a potential mechanism whereby genetic variation influences melatonin signaling in the brain, impacting an individual’s ability to cope with shift work schedules.

Melatonin, a hormone regulated by the circadian rhythm, plays a crucial role in maintaining our biological night. Reduced signaling through melatonin receptors, particularly type 1A receptors, could make individuals more sensitive to nocturnal light exposure, disrupting their circadian rhythms and exacerbating symptoms of job-related exhaustion.

While the study focused on shift workers, its implications extend to anyone navigating irregular work schedules. Understanding the genetic underpinnings of job-related exhaustion could pave the way for personalized interventions and support systems tailored to individual needs.

This groundbreaking research underscores the complex interplay between genetics, circadian biology, and workplace well-being. By shedding light on the genetic factors influencing tolerance to shift work, the study offers valuable insights into strategies for promoting resilience and mitigating the adverse effects of irregular work schedules.

Environmental Factors

Job-related exhaustion is influenced by a variety of environmental factors, each contributing to the overall stress experienced in the workplace. Understanding these factors is essential for organizations and individuals seeking to mitigate burnout and promote well-being. Here are some key environmental factors known to affect job-related exhaustion:

  1. Workload: Perhaps the most obvious factor, workload refers to the volume and intensity of tasks assigned to an individual within a given timeframe. High workloads, especially when combined with tight deadlines and insufficient resources, can lead to feelings of overwhelm and exhaustion. 
  2. Job Demands: Beyond sheer volume, the nature of job demands can also impact exhaustion levels. Jobs that require constant multitasking, decision-making, and emotional labor are particularly draining. For instance, healthcare professionals often face high emotional demands due to the need for empathy and compassion in patient care.
  3. Autonomy and Control: The degree of autonomy and control employees have over their work can significantly influence their exhaustion levels. Jobs that offer greater autonomy allow individuals to make decisions and manage their workload according to their preferences and abilities, which can buffer against burnout. Conversely, a lack of autonomy, micromanagement, and rigid control structures can exacerbate feelings of frustration and helplessness, leading to heightened exhaustion levels.
  4. Social Support: The presence of supportive relationships and a positive social environment in the workplace can act as a protective factor against burnout. Coworker support, supervisor support, and a sense of belonging within the organization contribute to employee well-being and resilience. 
  5. Organizational Culture: The values, norms, and practices upheld within an organization can either foster or hinder employee well-being. Cultures that prioritize work-life balance, employee recognition, and open communication tend to have lower rates of burnout. Conversely, toxic cultures characterized by competitiveness, fear of failure, and lack of transparency can fuel exhaustion and disengagement. Studies have shown that organizational culture significantly influences burnout levels, with supportive cultures associated with lower exhaustion rates.
  6. Work Environment: Physical aspects of the work environment, such as noise levels, lighting, and ergonomic conditions, can also impact exhaustion. Poorly designed workspaces or environments that lack amenities for relaxation and rejuvenation can contribute to stress and fatigue. Research suggests that optimizing the work environment to promote comfort and well-being can help reduce exhaustion levels and enhance productivity.

In sum, job-related exhaustion is influenced by a multitude of environmental factors spanning workload, job demands, autonomy, social support, organizational culture, and the physical work environment. Recognizing and addressing these factors is crucial for preventing burnout and promoting employee well-being in today’s demanding workplaces.

Is Job-Related Exhaustion a Medical Condition?

Job-related exhaustion, commonly referred to as burnout, is not classified as a medical condition in itself. However, it is recognized as a significant occupational phenomenon with profound implications for physical and mental health. 

The World Health Organization (WHO) defines burnout as a syndrome resulting from chronic workplace stress that has not been successfully managed. While not listed as a medical condition in the International Classification of Diseases (ICD), burnout is acknowledged as a legitimate concern impacting individual well-being and organizational performance.

Research indicates that burnout is associated with a range of adverse health outcomes, including increased risk of cardiovascular disease, depression, anxiety, and decreased immune functioning. 

A systematic review published in the Journal of Occupational Health Psychology found consistent evidence linking burnout to various physical and psychological health problems. Additionally, burnout can have detrimental effects on work performance, leading to decreased productivity, absenteeism, and turnover.

Although burnout itself is not a diagnosable medical condition, its consequences can have profound implications for individuals and organizations. Recognizing the signs of burnout and implementing interventions to address workplace stressors is essential for preventing its negative impact on health and well-being. 

Moreover, acknowledging burnout as a legitimate occupational hazard underscores the importance of promoting healthier work environments and supporting employees’ mental and emotional resilience.

What are the Symptoms of Job Burnout?

Job burnout manifests through a variety of physical, emotional, and behavioral symptoms, which can significantly impair an individual’s well-being and performance in the workplace. Here are some common symptoms of job burnout supported by scientific research:

  • Chronic Fatigue: Persistent feelings of exhaustion that go beyond typical tiredness and may not be alleviated by rest or relaxation. This fatigue can impact both physical and mental energy levels, leading to decreased motivation and productivity.
  • Cynicism and Detachment: A negative and cynical attitude towards work, colleagues, and tasks. Individuals experiencing burnout may become emotionally distant, disengaged, or indifferent to their responsibilities and the goals of their organization.
  • Reduced Efficacy: Feelings of inefficacy and decreased confidence in one’s abilities to perform tasks effectively. Burnout can erode self-esteem and undermine a person’s sense of accomplishment, leading to self-doubt and diminished job satisfaction.
  • Physical Symptoms: Burnout can manifest in various physical symptoms, including headaches, muscle tension, gastrointestinal issues, and sleep disturbances. These physical manifestations are often linked to chronic stress and can exacerbate feelings of exhaustion and discomfort.
  • Increased Irritability: Heightened irritability, impatience, or frustration in response to minor inconveniences or challenges. Individuals experiencing burnout may have a shorter fuse and struggle to regulate their emotions, leading to conflicts with colleagues and decreased interpersonal effectiveness.
  • Withdrawal from Responsibilities: Avoidance of work-related tasks or responsibilities, procrastination, or absenteeism. Burnout can lead individuals to disengage from their work duties as a coping mechanism to avoid further stress or feelings of overwhelm.
  • Impaired Concentration and Memory: Difficulty focusing, maintaining attention, or retaining information. Burnout can impair cognitive functioning, leading to decreased performance and effectiveness in completing tasks.

Recognizing these symptoms is crucial for early intervention and prevention of burnout. Employers and individuals alike should prioritize strategies to manage stress, promote work-life balance, and foster a supportive work environment to mitigate the risk of burnout and promote overall well-being.

Can You Recover from Job Burnout Without Quitting Your Work?

Yes, it is possible to recover from job burnout without quitting your work. Research suggests that implementing targeted interventions and making changes to both individual behaviors and organizational practices can facilitate burnout recovery. 

Studies have found that interventions such as cognitive-behavioral therapy, mindfulness-based stress reduction, and relaxation techniques can effectively reduce burnout symptoms and improve well-being among individuals experiencing job-related exhaustion.

Additionally, organizational initiatives aimed at promoting work-life balance, providing social support, and addressing job demands can play a crucial role in burnout recovery. Creating a supportive work environment, fostering open communication, and offering resources for stress management can help individuals regain a sense of control and fulfillment in their roles.

It’s important to note that burnout recovery is a gradual process that requires commitment and effort from both the individual and the organization. By implementing evidence-based strategies and making systemic changes to address the root causes of burnout, individuals can often experience significant improvement in their well-being and job satisfaction without resorting to quitting their work.

Ways to Lessen Job-Related Exhaustion
