<h2>Understanding the Importance of Hydration</h2>
For high school athletes, maintaining optimal hydration is crucial for both performance and health. Proper hydration supports energy levels, aids in muscle function, and helps regulate body temperature. Dehydration can lead to decreased performance, cramps, fatigue, and even more serious health issues.

Young athletes often underestimate their hydration needs, especially when training or competing in warm weather. It's important to develop a hydration strategy that meets the demands of their sport and individual needs.

<h2>Signs of Dehydration</h2>
Recognizing the early signs of dehydration can help prevent it from affecting performance. Symptoms may include:
<ul>
 <li>Thirst</li>
 <li>Dry mouth</li>
 <li>Dark yellow urine</li>
 <li>Fatigue</li>
 <li>Dizziness</li>
</ul>

<figure id="figure-99peo9cbhmb6usliu"><img id="99peo9cbhmb6usliu" src="https://media.gettyimages.com/id/1239845000/photo/tired-runner-resting-after-exercise-in-city-outskirts.jpg?b=1&s=2048x2048&w=0&k=20&c=klX89h__guX-oHtW0BOOWuaq5EvBlv9JCFtTJ_zHPA8=" alt="dehydrated athlete" class="object-cover bg-gray-100" style="aspect-ratio: 16/9"></figure>

If these symptoms occur, it's important for athletes to take immediate action to rehydrate. Ignoring these signs can lead to more severe dehydration and potential health risks.

<h2>Hydration Strategies for Athletes</h2>
Developing an effective hydration plan involves a few key strategies. First, athletes should start their day well-hydrated and continue to drink fluids consistently throughout the day. Here’s a simple guideline:
<ol>
 <li>Drink 16-20 ounces of water two hours before exercise.</li>
 <li>Consume 8-10 ounces of fluid every 15-20 minutes during exercise.</li>
 <li>Replenish with 16-24 ounces of water for every pound lost during exercise.</li>
</ol>

Electrolytes also play a vital role in hydration, especially during prolonged or intense activities. Sports drinks can be a good source of electrolytes, but it's crucial to choose options low in added sugars.

<h2>Hydrating Foods</h2>
Athletes can also incorporate water-rich foods into their diet to aid hydration. Fruits like watermelon, oranges, and strawberries, as well as vegetables like cucumbers and lettuce, have high water content. These foods not only provide hydration but also essential vitamins and minerals that support athletic performance.

Milk is another excellent option, providing both fluid and nutrients such as protein and calcium. It's particularly beneficial post-exercise for recovery.

<h2>Monitoring Hydration Levels</h2>
A simple way for athletes to monitor their hydration status is by checking their urine color. Ideally, urine should be light yellow. Darker shades can indicate dehydration, while clear urine may suggest overhydration.

Athletes should also pay attention to how they feel during training and competitions. Fatigue or a decline in performance might signal the need for additional fluids.

<h2>Conclusion</h2>
Hydration is a key component of an athlete's overall training regimen. By understanding the importance of staying hydrated, recognizing signs of dehydration, and implementing effective hydration strategies, high school athletes can enhance their performance and well-being. Prioritizing hydration will not only support their current athletic endeavors but also establish healthy habits for the future.

The Ultimate Guide to Hydration for High School Athletes

<h2>Performance in Temperature: How Physical Operations Vary in Different Settings</h2><h3>Colder Temperatures</h3>Metabolic Changes:<ul><li>Exposure to colder temperatures, around 10-16˚C (50-60˚F) increases metabolic rate due to shivering and thermoregulation demands as your body works to regulate its temperature in an cooler outside environment. As metabolic rate increases, more energy - from food and water - is expended/used, meaning that many athletes may require more carbohydrates and calories to sustain peak performance.<ul><li>One solution to making sure energy is sustained is by layering clothing—such as jackets, gloves, and thermal pants—to help maintain a stable core body temperature. Layering traps body heat and prevents excessive energy loss or shivering, allowing muscles to stay warm and reducing the risk of stiffness or injury.&nbsp;</li><li>Eating warmer foods in colder temperatures, like soup 1–2 hours before a race, can help maintain core body temperature and reduce the onset of shivering. A heated, carbohydrate-rich meal not only provides quick energy but also supports thermogenesis, making it easier for the body to focus energy on performance rather than temperature regulation.&nbsp;</li></ul></li></ul>Hydration Risks:<ul><li>Cold weather can blunt thirst cues—making individuals feel less inclined to drink water. Because the mouth usually does not feel dry and the physical signs of dehydration are less noticeable in cooler temperatures, athletes may underestimate their hydration needs. The risk of dehydration remains significant in cooler weather due to continued fluid loss through respiration, sweat, and other metabolic processes—even if it is less noticeable.<ul><li>Proactive hydration—drinking water consistently throughout the day rather than waiting 30 minutes before or during exercise—can significantly support an athlete’s performance in cooler temperatures by maintaining optimal blood flow, regulating internal body temperature, and preventing the hidden effects of dehydration that often go unnoticed in the cold.</li></ul></li></ul>Injury Risks:<ul><li>In colder environments, muscles are often found to be stiff and more prone to injury, especially as the body prioritizes maintaining core temperature, which can lead to reduced blood flow to the extremities, especially muscles. This can cause muscles to become stiff and less flexible, making them more prone to strains, tears, or pulls during physical activity. The reduced elasticity and flexibility can increase the likelihood of muscle strains or tears during explosive movements like sprints or jumps.</li><li><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">As the body attempts to keep warm in cooler environments, shivering may occur, causing involuntary muscle contractions. Although shivering helps generate heat, the energy it uses can also cause muscle fatigue and reduce the efficiency of muscle contractions, making the muscles more prone to strain or injury.<ul><li><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Proper Warm-Up: Ensure a comprehensive warm-up that includes dynamic stretches, light jogging, and joint mobility exercises to prepare the body for the physical demands of exercise. Consider starting with a few minutes of light activity in a sheltered, warmer area if possible.</li><li><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Layering Clothing: Wear appropriate clothing layers to keep muscles warm. This includes moisture-wicking materials, thermal clothing, and insulating layers like gloves, hats, and socks to prevent heat loss. Thermal gear can help maintain core body temperature and reduce the risk of stiffness or injury.</li><li><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Gradual Intensity: Start workouts or exercises at a lower intensity to allow muscles to gradually adjust to movement. Avoid jumping into intense physical activity immediately in cold environments.</li><li><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Stay Hydrated: While cold temperatures may not make you feel thirsty, dehydration can still occur. Maintain hydration levels by drinking water or sports drinks regularly to ensure proper circulation and muscle function.</li><li><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Proper Footwear: Wear non-slip footwear with adequate insulation to prevent slips, falls, and cold-induced muscle injuries, especially if you're training outdoors on snow or ice.</li><li><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Monitor Your Body: Be mindful of early signs of shivering, fatigue, or joint pain, which could indicate the body is struggling to adapt to the cold. Take regular breaks, and if conditions worsen, seek shelter and warmth.&nbsp; </li></ul></li></ul><h3>Hotter Temperatures</h3>Core Temperature and Performance<ul><li>Hot environments elevate core body temperature quickly as the body works - using water, energy, etc. - to cool itself down, which can reduce endurance performance due to early fatigue, dehydration, and overheating. <ul><li>&nbsp;A ~1°C rise in core body temperature before exercising in the heat significantly reduced endurance performance in the morning but not in the evening. This means that even a small increase in internal body temp—like from staying out in the sun, warming up too aggressively, or wearing too many layers—can cause fatigue to set in earlier during workouts or competitions if they’re in the morning.&nbsp;</li><li>Don’t sit in the sun, wear thick layers, or take hot showers right before morning practice or races. Consistent exposure to these condtitions increases core temperature, makes it harder to cool off before a practice/performance, and does not work your muscles in the direct way a warm-up lap or dynamic exercises would. </li><li>Use a cold towel on your neck, drink icy water, or stay in air-conditioned spaces close to the time of warm-up. Maintaining a cooler body will decrease core temperature and allow you to operate at your best.</li><li>A cold, carb-rich snack (like fruit, oatmeal, or toast) can support energy without warming your core further. &nbsp;<span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">When you eat before a workout, your body begins digesting food—this process raises your internal body temperature, especially with large or heavy meals. Choosing to avoid adding extra heat from digestion by comsuming foods with less required digestion will help. Drink cool water or an electrolyte drink in small sips starting 1–2 hours before exercise. Hydration will allow your body to cool itself down</li></ul></li></ul>Hydration:<ul><li>Increased Sweat Loss<ul><li>Study: Cheuvront &amp; Kenefick (2014) found that in hot environments, sweat rates can exceed 1–2.5 liters/hour, even in moderate activity.</li><li>Athletes lose fluids faster than they can drink, especially during high-intensity or prolonged exercise, increasing risk of dehydration, especially if pre-exercise hydration is poor.</li></ul></li><li>&nbsp;Delayed Thirst Response<ul><li>Study: Sawka et al. (2007) observed that the body's thirst mechanism lags behind actual fluid loss in the heat.</li><li>Athletes often underestimate how much water they need and don’t feel thirsty until they’re already dehydrated by 1–2% of body weight.</li></ul></li><li>Cognitive Performance:<ul><li>Extreme heat and cold can stress the body and distract the mind, while moderate temperatures allow for clearer thinking and better concentration during exercise or competition.</li></ul></li><li>&nbsp;Performance Drops with Mild Dehydration<ul><li>Study: Casa et al. (2010) found that just 2% dehydration can impair endurance performance, increase perceived effort, and elevate core temperature.</li><li>Even mild dehydration leads to early fatigue, slower running times, and increased risk of heat illness.</li></ul></li><li>&nbsp;Electrolyte Imbalance Risks<ul><li>Study: Bergeron et al. (2005) studied youth athletes and noted that excessive sweating in hot, humid environments without electrolyte replacement led to muscle cramps and performance decline.</li><li>Water alone may never be enough—sodium and potassium, common electrolytes, must be replenished, especially during longer sessions or repeated training days.<ul><li>Prehydrate: Start hydrating the night before and drink 16–20 oz of fluid 1–2 hours before exercise in heat.</li><li>Drink during workouts: Aim for 6–8 oz every 15–20 minutes, or more if sweat rate is high.</li><li>Use electrolytes: Choose a sports drink or add salt to water during long/hot sessions. </li><li>Monitor urine color: Pale yellow = hydrated. Dark = drink more water.</li><li>Cool your fluids: Cold drinks are absorbed faster and help reduce core temperature.</li></ul></li></ul></li></ul><h3>Indoor Training and Dry Atmospheres</h3>Humidity:<ul><li>Performance Optimization: Training and competing in environments with lower humidity has been proven, by multiple studies, to help maintain endurance performance, especially in hot conditions.​</li><li>Thermoregulation: Lower humidity facilitates more effective sweat evaporation, meaning that the sweat used to cool the body down evaporated effectively, aiding the regulation of body temperature regulation during exercise.​</li><li>A study by Cheuvront et al. (2008) found that fluid loss in low-humidity environments (20-30%) could still lead to significant dehydration, particularly in endurance events. Despite better evaporative cooling in these conditions, the performances of athletes who didn’t consistently rehydrate with fluids were impared due to early fatigue and reduced performance.<ul><li>Hydration Strategies: Even in low-humidity environments, athletes should monitor hydration levels, as sweat evaporation can lead to significant fluid loss without the sensation of being overly sweaty.​ Consuming 16-20oz of water 2-3 hours before an exercise/training session can ensure proper hydration</li><li>Electrolyte Drinks: In dry environments, athletes sweat out important electrolytes (sodium, potassium, magnesium). Drinking sports drinks containing electrolytes or using electrolyte tablets can help maintain fluid balance, prevent cramping, and avoid fatigue.</li><li>Post-Exercise Hydration: After exercise, it's important to rehydrate with both water and electrolytes to replenish the fluids lost during the workout. Drinking water or electrolyte drinks within the first 30 minutes after exercise can enhance recovery.</li><li>Carbohydrate-Rich Foods: For long training sessions or races, athletes should consume carbohydrates before and during exercise to help maintain energy levels and support hydration. Foods like bananas, energy gels, or sports bars are great options.</li></ul></li></ul><h3>Moderate Temperature</h3>In moderate temperatures (typically ranging from around 18-24°C or 64-75°F), athletes face fewer challenges compared to exreme hot or cold environments; however, there are still key considerations that can affect hydration, energy expenditure, and overall performance.Key Strategies for Athletes in Moderate Temperatures:<ul><li>Routine Hydration: Hydrate CONSISTENTLY throughout the day and drink small sips of water or electrolyte drinks during long workouts.</li><li>Energy-Dense Foods: Eat a well-balanced pre-workout meal that includes carbohydrates and protein to fuel exercise, and consume post-workout recovery meals to restore energy.</li><li>Layering Clothing: Dress in light, moisture-wicking fabrics to stay comfortable and help with sweat evaporation.</li><li>Warm-Up and Cool-Down: Perform dynamic warm-ups to prepare muscles and cool-down stretches to improve recovery without overexerting.</li><li>Listen to Your Body: In moderate conditions, athletes can perform at a high level of exertion for extended periods, but it is important to still monitor for signs of dehydration or fatigue, particularly on longer training days or events.</li></ul>

Performance in Temperature: How Physical Operations Vary in Different Settings

<h3>The Importance of Drinking Water</h3>We all know that humans need water to live. It is essential for many bodily functions that provide the body with energy: maintaining homeostasis, regulating body temperature, and supporting cellular respiration. Without water, the average human can only survive a few days. However, many people overlook just how much water they should be drinking daily, especially high school athletes. Hydration needs vary depending on factors such as age, environment, activity level, and overall health, making it especially critical for high school athletes to understand their unique requirements.The Impact of Dehydration on Performance Dehydration has been linked to a decline in athletic performance. A study published in Frontiers in Physiology (2021) found that dehydration significantly impairs endurance, strength, and cognitive function in athletes (PMC8625246). This is particularly concerning for high school athletes who often participate in intense training sessions and competitions. Even mild dehydration—defined as a body mass loss of 1-2% due to fluid deficits—can reduce aerobic performance and increase notable exertion/effort. When athletes ar dehydrated, their blood volume decreases, and, as a result, the oxygen delivery to muscles is reduced and&nbsp;they experience an overall decline in efficiency.Increased Risk of Injury and Muscle Damage Hydration plays a crucial role in preventing injuries. A Sports Medicine study (2021) found that dehydration leads to impaired neuromuscular control and an increased likelihood of musculoskeletal injuries in athletes (PMC8566643). Muscle fibers and tendons rely on water to maintain their structural integrity and function, as it helps keep the proteins and connective tissues within muscles hydrated and replenished. Proper hydration also supports the production of synovial fluid, which lubricates joints and reduces friction. When you're well-hydrated, your muscles can contract and relax more efficiently, maintaining their elasticity and reducing stiffness. On the other hand, dehydration leads to a decrease in intracellular and extracellular fluid, making muscle fibers more rigid and prone to microtears, strains, and cramps. Additionally, inadequate fluid intake can lead to a higher risk of heat-related illnesses such as heat cramps, heat exhaustion, and heat stroke—conditions that can be life-threatening if not properly managed.Hydration and Liver Health While dehydration is commonly associated with muscle cramps and fatigue, it also has systemic effects, including liver dysfunction. A study in the International Journal of Molecular Sciences (2021) highlights how dehydration can induce oxidative stress and inflammation in the liver, potentially leading to long-term damage (PMC8566439). Since the liver plays a key role in detoxifying the body and metabolizing nutrients essential for recovery, dehydration-induced liver stress can hinder an athlete’s ability to recover from training and maintain optimal health.Hydration and Cognitive Function Beyond its physical effects, dehydration has significant consequences on cognitive function, reaction time, and mental clarity. A study published in Nutrients (2017) found that even mild dehydration (1-2% body weight loss in fluids) can impair short-term memory, concentration, and decision-making skills in athletes (PMC5640004). In high school sports, where split-second decisions, coordination, and focus are crucial, even slight dehydration can put an athlete at a disadvantage.<ul><li>Reduced Cerebral Blood Flow: The brain is highly sensitive to fluid balance. When dehydration reduces blood volume, cerebral perfusion (blood flow to the brain) is decreased. Studies that have used functional MRI scans (fMRI) have shown that hypohydration (a state of dehydration) leads to decreased activity in regions associated with attention, memory, and executive function(D’Anci et al., 2009). With less blood flow, reaction times are slower, motor coordination is imparies, and mental fatigue is increased—all detrimental to athletic performance.</li><li>Electrolyte Imbalance and Neural Communication: Hydration is essential for maintaining electrolyte balance, particularly sodium, potassium, and chloride, which play a role in regulating neuronal signaling and synaptic transmission. When you are dehydrated, electrolyte imbalances alter the electrical activity of your neurons, leading to slower nerve conduction and impairments in focus, decision-making, and motor control. This is particularly dangerous in sports requiring rapid reflexes and precision, such as sprinting, basketball, or soccer.</li><li>Increased Cortisol and Perceived Stress: Dehydration elevates levels of cortisol, a stress hormone that negatively affects cognitive performance, emotional stability, and memory recall. In high school athletes, increased cortisol due to dehydration can contribute to poor mental resilience under pressure, making it harder to stay composed in competitive settings.</li><li>Neurotransmitter Disruption:&nbsp;<span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Dehydration alters neurotransmitter activity and affects cognitive performance, mood regulation, and mental endurance. It indicates that dehydration can lead to lower dopamine and serotonin availability, contributing to increased fatigue, reduced motivation, and impaired mental performance—all of which are critical for high school athletes. (Cian et al., 2019, PMC8566439). <span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Athletes experiencing dehydration often report feeling more fatigued, less motivated, and more irritable, which can decrease competitive drive and focus.</li><li>Blood-Brain Barrier Permeability and Neuroinflammation: Severe dehydration has been linked to increased permeability of the blood-brain barrier (BBB), allowing harmful substances and inflammatory markers to enter the brain more easily (Zhang et al., 2015). This can trigger neuroinflammation, which may contribute to brain fog, slowed cognition, and prolonged recovery times after physical exertion. <span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);"> Results from cognitive impariments: </li></ul><ul><li>Slower reaction times, leading to delayed responses in fast-paced sports.</li><li>Decreased focus and coordination, increasing the risk of errors and poor performance.</li><li>Poor memory recall and decision-making, affecting strategic gameplay and split-second choices.</li><li>Increased mental fatigue, making it harder to sustain performance over long training sessions or competitions.</li></ul>How Much Water Should High School Athletes Drink? There is no universal hydration guideline, everyone's bodies have different needs and what might work for one person may not work for the other. However general recommendations suggest that high school athletes should:<ol><li>Drink at least 2-3 liters (70-100 oz, 8-12 cups) of water throughout day with increased intake during strenuous exercise.</li><li>Follow the The American College of Sports Medicine guidelines, which reccomend consuming 16-20 ounces of water 2-3 hours before exercise, 8-10 ounces every 15-20 minutes during activity, and replace lost fluids post-exercise. Electrolyte-rich drinks may be beneficial for prolonged workouts, especially in hot conditions.</li><li>Consider adding electrolytes to water, or consuming eletrolyte drinks, especially for prolonged workouts, even more so in hot and humid conditions, when water loss is greater.</li></ol>References:Cian, Christophe, et al. “Influence of Variations in Body Hydration on Cognitive Function: Effects of Hyperhydration, Heat Stress, and Exercise-Induced Dehydration.” Frontiers in Physiology, vol. 10, 2019, p. 1046, <a href="https://doi.org/10.3389/fphys.2019.01046" data-mce-href="https://doi.org/10.3389/fphys.2019.01046">https://doi.org/10.3389/fphys.2019.01046</a>.

The Role of Water in Muscle Function, Injury Prevention, and Cognitive Ability

<h3>The Relationship Between Stress and Food</h3>Stress is inevitable—whether from school, training, or the daily demands of life, it always finds a way into your life. However, what you might not realize is that the food you eat directly influences your ability to handle stress. My goal is to help you understand this connection and allow you to make informed dietary choices that will support your mental resilience rather than amplify stress responses.How Stress Affects Your Body: When under pressure, the body shifts into fight-or-flight mode, activating the sympathetic nervous system. This triggers the release of stress hormones, including:<ol><li>Cortisol: Increases blood sugar levels and inflammation, providing immediate energy but also contributing to long-term metabolic issues if chronically elevated.</li><li>Adrenaline: Enhances alertness and reaction time but can lead to energy crashes once its effects wear off.</li><li>Neurotransmitter Fluctuations: Affect mood, focus, and motivation, leading to anxiety, irritability, and fatigue. The way you fuel your body can either stabilize these responses or exacerbate stress. Some foods help regulate cortisol and neurotransmitter balance, while others contribute to inflammation, energy fluctuations, and cognitive impairment.</li></ol><h3>Foods &amp; Activities That Worsen Stress &amp; Mental Fatigue</h3>The foods you consume can either help regulate your stress levels or make them worse. Some foods support the balance of cortisol and neurotransmitters, while others can increase inflammation, energy fluctuations, and cognitive impairment. 1. Refined Sugars &amp; Processed Carbohydrates Examples: Soda, candy, white bread, fast food, pastriesWhen you consume refined sugars and highly processed carbs, your body experiences rapid blood glucose spikes. This sudden surge in glucose forces your pancreas to release a large amount of insulin to restore balance. The subsequent crash in blood sugar levels can leave you feeling tired, irritable, and more prone to stress. This rollercoaster of energy not only disrupts your mood but also increases the production of cortisol—a stress hormone that, when elevated chronically, can impair cognitive function and worsen anxiety.2. Excessive Caffeine &amp; Energy Drinks Examples: High-caffeine coffee, energy drinks, caffeinated sodas (Celsius, Alani, Monster, Coffee..)Caffeine in moderate amounts can be a stimulant; however, when consumed in excess, it leads to heightened levels of cortisol and adrenaline. These chemicals overstimulate your nervous system, which may temporarily increase alertness but also promote feelings of anxiety and jitteriness. Furthermore, high caffeine levels interfere with adenosine—a neurotransmitter responsible for sleep regulation—resulting in disrupted sleep patterns that compound stress and reduce overall mental clarity.3. Processed &amp; Fried Foods (High in Trans Fats) Examples: Fast food, chips, packaged snacks (Pringles, Chick-fil-a, caramel corn)Foods high in trans fats, omega-6 fatty acids and unhealthy processed oils provoke a state of chronic inflammation in the body. This inflammatory response affects not only your muscles and joints but also the gut—the body’s “second brain.” Since about 90% of serotonin (a key mood-regulating neurotransmitter) is produced in the gut, inflammation here can directly impair your mood and increase anxiety. Over time, the persistent inflammation from these foods can lead to a diminished stress threshold and greater susceptibility to fatigue.4. Skipping MealsRegularly skipping meals, whether due to a busy schedule or a misguided notion of “not feeling hungry,” deprives your body of the consistent energy it needs. When you skip meals, your body doesn't receive a fresh supply of glucose—the brain's primary fuel. Without regular food intake, blood sugar levels drop (a state known as hypoglycemia), which means the brain gets less energy to perform its functions. Since cognitive processes like concentration, memory, and decision-making rely on a steady energy source, a low blood sugar level can lead to decreased cognitive function and make it harder to focus. &nbsp;This not only makes it harder for your body to manage stress effectively but also increases cortisol production as your body attempts to compensate for low energy. In essence, neglecting to eat at regular intervals forces your body into a constant state of stress, contributing to mental fatigue and mood instability.<h3>&nbsp; Foods That Reduce Stress &amp; Boost Mental Resilience </h3>While some choices exacerbate stress, others provide the building blocks for a calmer, more resilient mind. These nutrient-dense foods work by stabilizing blood sugar, reducing inflammation, and supporting the production of mood-regulating neurotransmitters. 1. Complex Carbohydrates for Steady Energy Examples: Oats, quinoa, brown rice, whole grain bread, sweet potatoesComplex carbohydrates—found in oats, quinoa, brown rice, whole grain bread, and sweet potatoes—are digested slowly, which provides a gradual, steady release of glucose into the bloodstream. This controlled energy release helps maintain stable blood sugar levels and prevents the rapid spikes and drops that can trigger stress responses. In addition, a stable blood sugar level supports the synthesis of serotonin, a key neurotransmitter involved in mood stabilization and anxiety reduction. Essentially, these carbs create an energy environment that helps the body better manage stress.2. Healthy Fats to Support Brain Function Examples: Avocados, olive oil, nuts, seeds, salmon, dark chocolateHealthy fats—especially omega-3 fatty acids—play a pivotal role in reducing inflammation and supporting brain health.&nbsp;Omega-3s help modulate cortisol production and balance dopamine levels, both vital for regulating mood and motivation. By reducing chronic inflammation and supporting optimal brain function, these fats can accelerate recovery from stress. In short, including healthy fats in your diet enhances the brain’s resilience to stress.3. High-Quality Proteins &amp; Amino Acids Examples: Eggs, lean meats, Greek yogurt, beans, tofu, nutsHigh-quality proteins supply essential amino acids like tryptophan and tyrosine. These amino acids serve as precursors for serotonin and dopamine, neurotransmitters that are fundamental to mood regulation, sleep, and focus. A diet rich in complete proteins ensures that the body has the necessary components for tissue repair and muscle recovery, which supports sustained energy levels. This comprehensive amino acid profile helps counteract stress-induced fatigue and bolsters overall mental well-being.4. Magnesium-Rich Foods for Relaxation Examples: Dark leafy greens, bananas, nuts, seeds, dark chocolateMagnesium-rich foods—such as dark leafy greens, bananas, nuts, seeds, and dark chocolate—play a pivotal role in promoting relaxation and reducing stress. Magnesium helps modulate the body’s stress response by blocking the excessive release of cortisol, the primary stress hormone, and by supporting proper nerve and muscle function. This mineral contributes to a state of calm and aids in preventing the physical manifestations of stress. Ensuring an adequate intake of magnesium is crucial for lowering anxiety levels and maintaining a balanced, relaxed state. &nbsp; 5. Probiotics &amp; Gut-Healthy Foods Examples: Yogurt, kimchi, sauerkraut, kefir, misoA healthy stomach is crucial for overall well-being, as it plays a significant role in the production of serotonin. Probiotic-rich foods encourage a balanced gut microbiome, which can improve mood and enhance your body’s ability to manage stress. A well-nourished gut supports not only digestion but also the immune system and mental resilience. A balanced gut microbiome, an ecosystem of bacteria supported by probiotic-rich foods like yogurt, fermented vegetables, olives, etc. plays a crucial role in producing neurotransmitters such as serotonin, which are essential for mood regulation. These beneficial bacteria help maintain the integrity of the gut barrier, reducing systemic inflammation that can trigger stress responses. Additionally, the gut communicates with the brain via the vagus nerve, influencing the HPA axis and moderating the body's stress response. In essence, a healthy gut environment promotes a stable mood and enhances resilience to stress through these interconnected biological pathways.6. Staying Hydrated Examples: Water, herbal teas, coconut waterEven mild dehydration can threaten cognitive function and elevate cortisol levels.&nbsp; 75% of fhe brain is composed from water. Adequate hydration helps maintain blood volume and viscosity, ensuring that oxygen and nutrients are efficiently delivered to brain cells. When you're dehydrated, blood flow can decrease, leading to reduced oxygenation of brain tissue. This can impair cognitive processes such as concentration, memory, and decision-making. Dehydration is perceived by the body as a form of physiological stress. When the body perceives this stress, the hypothalamic-pituitary-adrenal (HPA) axis is activated, the body’s central stress response system. The system begins when the hypothalamus detects stress and secretes corticotropin-releasing hormone (CRH). This hormone then prompts the pituitary gland, located just beneath the hypothalamus, to release adrenocorticotropic hormone (ACTH). ACTH travels through the bloodstream to the adrenal glands—situated on top of the kidneys—signaling them to produce cortisol and other related hormones. Cortisol, often referred to as the "stress hormone," plays a crucial role in mobilizing energy, regulating metabolism, and modulating the immune response during stressful events. Elevated cortisol levelscan contribute to feelings of anxiety, fatigue, and even hinder cognitive and athletic performance over time. Research has shown that even mild dehydration (as little as a 2% loss in body weight due to water loss) can significantly impact cognitive function and increase cortisol levels. Consistent fluid intake is a simple yet powerful way to reduce the physical symptoms of stress, and, as a result of constantly being hydrated, you will be able to focus more in class, on the field<h3>&nbsp; Best Eating Habits to Manage Stress </h3>Incorporating smart dietary choices into your daily routine can have a transformative impact on your stress levels and overall mental resilience. Here are some actionable strategies:<ul><li>Balance Every Meal: At every meal make sure to include a mix of proteins, healthy fats, and complex carbohydrates to ensure a steady supply of energy throughout the day.</li><li>Eat Regularly: Avoid skipping meals by planning small, frequent snacks like granola, almonds, etc. that keep your blood sugar levels stable throughout the day. Make sure to eat breakfast, lunch, and &nbsp;dinner :)</li><li>Limit Unhealthy Options: Reduce the consumption of refined sugars, processed foods, and excessive caffeine. This will help to minimize inflammatory responses to stress and energy crashes.</li><li>Boost Omega-3 Intake: Incorporate fatty fish, walnuts, and flaxseeds to counteract inflammation and support brain health.</li><li>Prioritize Nutrient-Dense Foods: Gradually shift your diet to focus on whole, unprocessed foods that provide a full spectrum of vitamins, minerals, and antioxidants to support optimal body function. Take more time to look at the contents in the food you're eating and their nutrition values.</li><li>Stay Hydrated: Drink at least eight glasses of water daily to keep your brain and body functioning at their best. Hydration is important as an athlete, whether you're training or resting. By understanding how specific foods affect your body's stress responses, you can take control of your diet and, in turn, your overall mental well-being. Small, intentional changes in your eating habits can pave the way to reduced anxiety, enhanced cognitive function, and a more resilient, balanced life.</li></ul>Sources:<ol><li>National Institute of Mental Health (NIMH). “5 Things You Should Know About Stress.” National Institutes of Health, U.S. Department of Health and Human Services, <a href="https://www.nimh.nih.gov/health/publications/stress">https://www.nimh.nih.gov/health/publications/stress</a>.</li><li>Harvard Health Publishing. “Nutritional Psychiatry: Your Brain on Food.” Harvard Medical School, 9 Nov. 2021, <a href="https://www.health.harvard.edu/blog/nutritional-psychiatry-your-brain-on-food-201511168626">https://www.health.harvard.edu/blog/nutritional-psychiatry-your-brain-on-food-201511168626</a>.</li><li>American Psychological Association (APA). “Stress Effects on the Body.” American Psychological Association, <a href="https://www.apa.org/topics/stress/body">https://www.apa.org/topics/stress/body</a>.</li><li>Gomez-Pinilla, Fernando. “Brain Foods: The Effects of Nutrients on Brain Function.” Nature Reviews Neuroscience, vol. 9, no. 7, 2008, pp. 568–578. <a href="https://doi.org/10.1038/nrn2421">https://doi.org/10.1038/nrn2421</a>.</li><li>Miller, Gregory E., and Edith Chen. “Unfavorable Socioeconomic Conditions in Early Life Presage Expression of Pro-Inflammatory Phenotype in Adolescence.” Psychosomatic Medicine, vol. 69, no. 5, 2007, pp. 402–409. <a href="https://doi.org/10.1097/PSY.0b013e318068fcf9">https://doi.org/10.1097/PSY.0b013e318068fcf9</a>.</li><li>Gibson, Edward L. “Emotional Influences on Food Choice: Sensory, Physiological and Psychological Pathways.” Physiology &amp; Behavior, vol. 89, no. 1, 2006, pp. 53–61. <a href="https://doi.org/10.1016/j.physbeh.2006.01.024">https://doi.org/10.1016/j.physbeh.2006.01.024</a>.</li><li>Benton, David. “The Influence of Dietary Status on the Cognitive Performance of Children.” Molecular Nutrition &amp; Food Research, vol. 54, no. 4, 2010, pp. 457–470. <a href="https://doi.org/10.1002/mnfr.200900139">https://doi.org/10.1002/mnfr.200900139</a>.</li><li>Cleveland Clinic. “How Food Affects Your Mood.” Cleveland Clinic, 12 July 2022, <a href="https://health.clevelandclinic.org/how-food-affects-your-mood">https://health.clevelandclinic.org/how-food-affects-your-mood</a>. </li></ol>

The Relationship Between Stress and Food

red and black berries on brown wooden bowl

In their everyday lives, many high schoolers often dismiss what foods may not be the best for their health and tend to eat whatever makes them feel the best, or gives them short-term satisfaction. This may sound a bit harsh, especially for those who do make healthy choices, but in many cases, it is true. According to a study on lifestyle choices in high school athletes, titled: "The health-related determinants of eating pattern of high school athletes in Goiás, Brazil."&nbsp;The study on high school athletes in Goiás, Brazil, found that many young athletes engage in unhealthy eating patterns despite their involvement in sports. Key findings include:<ul><li>Skipping Breakfast: Over half (54.5%) of the athletes regularly skipped breakfast, a habit linked to using extreme weight-control methods such as vomiting or laxatives.</li><li>Low Fruit &amp; Vegetable Consumption: Only 8.9% of athletes consumed fruits and vegetables regularly, and this low intake was associated with the use of weight-loss pills.</li><li>High Sweet Consumption: About 30% of athletes regularly ate sweets, a behavior strongly linked to increased TV screen time and, more commonly, among female athletes.</li><li>Other Health Concerns: Many athletes reported feeling lonely, experiencing sleep disturbances, engaging in sedentary behavior, and being exposed to passive smoking. These results suggest that despite their active lifestyles, many young athletes struggle with poor nutrition choices, often influenced by weight concerns, media exposure, and lack of awareness.</li></ul>But what exactly are these unhealthy food choices that so many young people gravitate toward? More often than not, they fall into the category of ultra-processed foods—industrially manufactured products packed with additives, preservatives, artificial flavors, and excessive amounts of sugar, salt, and unhealthy fats. These foods are designed to be convenient, addictive, and hyper-palatable, making them easy to overconsume.For high schoolers, especially athletes, ultra-processed foods may seem like a quick and easy energy source. After all, grabbing a protein bar, a sugary sports drink, or a McDonald's hamburger meal between classes and practice feels efficient. However, despite their convenience, these foods provide little to no real nutritional value. Worse, they may actually be working against athletic performance and overall health._-_-_-_-_-_-_-_-_-_-__-_-_-_-_-_-_-_-_-_-__-_-_-_-_-_-_-_-_-_-__-_-_-_-_-_-_-_-_-_-__-_-_-_-_-<h2>Nutrient Deficiencies</h2>The persistent consumption of ultra-processed foods is linked to various risks, which can be categorized into short-term and long-term effects. I would like to start by discussing how ultra-processed foods can be linked to shorter term nutritent deficiencies when the athletes' diets are primarily based on UPFs. Ultra-processed foods are primarily composed of refined carbohydrates, processed oils, and artificial additives. They often lack essential nutrients critical for high school athletes, such as protein, fiber, vitamins, and minerals. While UPFs are sometimes fortified with synthetic vitamins, they do not provide the full spectrum of naturally occurring nutrients found in whole foods. Ultra Processed Foods&nbsp; Low Micronutrient Density → Deficiencies in Key Vitamins &amp; Minerals UPFs often contain refined sugars and low-fiber starches, which are quickly digested and absorbed, causing spikes and crashes in blood sugar levels. This leads to a gradual more unstable level of energy during training, which is vital for competition. The consumption of refined sugars and low-fiber starches in UPFs result, overall, in reduced endurance, mental fatigue, and slower recovery. These simple carbohydrates lack the complex carbohydrates and fiber found in whole foods like fruits, vegetables, and whole grains, which provide steady, sustained energy by slowing digestion and absorption. Whole foods also provide essential vitamins and minerals, such as magnesium and potassium, which are critical for muscle function and recovery. Deficiencies in these micronutrients can impair performance and delay recovery, as the body relies on them for muscle contraction, nerve function, and cellular repair processes. Inflammatory Fats &amp; Artificial Additives → Increased Injury Risk &amp; Slow Recovery Processed oils (such as soybean and palm oil) promote chronic inflammation, which can slow down recovery and increase injury risk. These fatty acids are classified in the omega-g category. In UPFs, the lack of omega-3 fatty acids (often found in whole foods like fish, nuts, and seeds) lead to increased muscle soreness and joint pain. Omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), regulate inflammation by influencing the production of signaling molecules called eicosanoids and specialized pro-resolving mediators (SPMs). Here is how this process works:<ol><li>Eicosanoid Pathway: Balancing Pro- and Anti-Inflammatory Signals Eicosanoids are hormone-like molecules derived from fatty acids that regulate inflammation. The key differences between omega-3 and omega-6 fatty acids are the type of eicosanoids they produce:</li></ol><ul><li style="list-style-type: none;" data-mce-style="list-style-type: none;"><ul><li>Omega-6 fatty acids (e.g., linoleic acid, arachidonic acid) → Pro-inflammatory eicosanoids<ul><li><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Omega-6s are converted into compounds like prostaglandins (PGE2) and leukotrienes (LTB4), which increase inflammation, pain, and immune responses.</li><li><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">While inflammation is necessary for healing, excess omega-6s (from processed oils, fried foods, etc.) create a chronic inflammatory state that can lead to joint pain, muscle soreness, and slow recovery.</li></ul></li></ul></li></ul><ul><li style="list-style-type: none;" data-mce-style="list-style-type: none;"><ul style="list-style-type: circle;" data-mce-style="list-style-type: circle;"><li>Omega-3 fatty acids (EPA and DHA) → Anti-inflammatory eicosanoids<ul style="list-style-type: square;" data-mce-style="list-style-type: square;"><li><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Omega-3 fatty acid, EPA, competes with omega-6s for enzymes like cyclooxygenase (COX) and lipoxygenase (LOX), reducing the production of pro-inflammatory molecules.</li><li><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);"><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Instead, the prostaglandins (PGE3) and leukotrienes (LTB5) found in omega-3 fatty acids, which are lipids (fats) that act as hormone-like substances in the body and <span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">promote inflammation by increasing blood flow, releasing pain-inducing chemicals, and activating immune cells,<span data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);"> are <span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">far less inflammatory than their omega-6 counterparts.</li><li><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">By shifting the balance toward EPA/DHA-derived eicosanoids, omega-3s naturally reduce excessive inflammation without completely shutting down the immune response.</li></ul></li></ul></li></ul><span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);"> <strong style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">2.

Why This Matters for Athletes: Without sufficient omega-3s, inflammation stays active for longer, delaying muscle repair and increasing soreness.</li><li>A diet high in omega-6s (common in ultra processed foods) shifts the body into a pro-inflammatory state, making athletes more susceptible to injuries and fatigue.</li><li>Whole foods rich in omega-3s (fatty fish, walnuts, flaxseeds) help balance eicosanoid production and promote faster recovery. Protein Quality &amp; Muscle RecoveryWhen it comes to muscle repair and growth, the body relies on the complete set of amino acids, which are the building blocks of protein. There are 20 amino acids in total, 9 of which are considered essential, meaning the body cannot synthesize them and must obtain them from food. These essential amino acids are particularly important for muscle recovery because they directly contribute to muscle protein synthesis, the process by which new muscle tissue is built to repair the damage caused by exercise.When a protein source has an incomplete amino acid profile, it means it lacks one or more of these essential amino acids, or the amount provided is insufficient. Without the full spectrum of essential amino acids, the body cannot effectively carry out muscle protein synthesis. This is because muscle growth requires all 9 essential amino acids to work together in a specific ratio. For example, leucine, one of the essential amino acids, plays a key role in activating the muscle-building process. If leucine is in short supply, the body struggles to initiate this repair and growth process.In addition, incomplete proteins often have lower bioavailability, which refers to how well the body can digest and absorb the protein. For example, plant-based proteins from soy or gluten are often less bioavailable compared to animal-based proteins, like those found in chicken, beef, eggs, or dairy. These animal proteins provide a more complete and easily absorbed set of amino acids, which makes them more efficient in supporting muscle recovery. On the other hand, when consuming proteins with low bioavailability, the body may not absorb all the amino acids it needs, hindering the repair and rebuilding of muscle fibers.&nbsp;Why to Care:&nbsp;For high school athletes, adequate protein intake is crucial for muscle repair and growth, especially during periods of intense training or competition. Incomplete or low-bioavailability proteins, often found in UPFs can hinder recovery, leading to slower muscle repair, increased risk of injury, and reduced performance. Consuming high-quality, complete proteins ensures that athletes can effectively rebuild muscle tissue, maintain strength, and optimize their overall athletic development. <span style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-style: var(--body-fontStyle, normal);">Many athletes rely on protein bars, energy drinks, and packaged snacks, assuming they are fueling properly, which, in terms of temporary energy boosts, they are. However, when looking at the long-term benefits through a bigger picture, they often lack the nutrients needed for sustained performance and recovery.</li></ul><h3>What You Can Do:</h3>When eating a meal before and after a workout, not necessarily right before a race, re-think what you are eating. For example, if you find yourself filling up on potato chips for lunch, sugary cereals like Fruit Loops in the morning, or processed meals like Lunchables in the evening, you may not be fueling your body properly. These ultra-processed foods (UPFs) are often low in essential nutrients and high in unhealthy fats, sugars, and refined carbohydrates, which can lead to energy crashes, slower recovery, and poor performance. Instead, focus on whole foods that provide complex carbohydrates, lean proteins, and healthy fats, such as whole grains, eggs, lean meats, and vegetables. These foods help stabilize your energy levels, support muscle repair, and improve overall athletic performance. By prioritizing nutrient-dense options, you’ll feel more energized, recover faster, and perform better in both practice and competition.Sources:Gupta, Rupal, et al.
