What Should You Drink When You Are Stressed in the Heat?

4 min read

A 2025 study from Liverpool John Moores University found that individuals with lower daily fluid intake exhibit a significantly stronger biological stress response, releasing higher levels of the stress hormone cortisol. Knowing what to drink when you are stressed in the heat is crucial for managing both physical and mental strain during high temperatures.

Quick Summary

Manage the physiological effects of heat and anxiety by choosing the right beverages. Understand how hydration and specific drinks can regulate stress hormones, cool the body, and support mental clarity during hot conditions.

Key Points

  • Hydration Lowers Cortisol: Studies show that staying well-hydrated helps regulate cortisol, the primary stress hormone, leading to a calmer response to stress.

  • Electrolytes are Key: Drinks rich in electrolytes like coconut water replenish minerals lost through sweat, which is vital for balancing hydration and nerve function.

  • Herbal Teas Offer Calm: Iced herbal teas like chamomile and peppermint are excellent caffeine-free options that provide soothing properties and can relieve tension.

  • Avoid Stimulants and Sugars: Steer clear of alcohol, high-caffeine energy drinks, and sugary sodas, as they can worsen dehydration and exacerbate anxiety.

  • Infused Water for Constant Hydration: Adding fruits and herbs like cucumber, mint, and lemon to water encourages consistent intake, helping to maintain hydration and mental clarity.

  • Mindful Beverage Choices: Being deliberate about what you drink can significantly influence your body's physiological response to heat and psychological stress, making you feel more composed and comfortable.

The Vicious Cycle of Heat and Stress

When temperatures rise, your body works harder to regulate its internal temperature. This process, which involves increased sweating and an accelerated heart rate, places additional physiological stress on the body. This physical strain, combined with psychological stress from daily life, can create a vicious cycle. Dehydration, a common consequence of heat, triggers an increase in cortisol, the body's primary stress hormone. This can lead to exacerbated feelings of anxiety, fatigue, and irritability. Choosing the right fluids is therefore a powerful tool for not only staying hydrated but also for actively calming your nervous system.

The Best Drinks for Staying Cool and Calm

To combat the twin threats of heat and stress, the ideal beverage provides both hydration and a calming effect. Here are some of the best options:

  • Coconut Water: This is nature’s sports drink, loaded with electrolytes like potassium and magnesium that are essential for proper hydration and nerve function. Dehydration leads to a loss of these minerals through sweat, and coconut water helps replenish them effectively. A sufficient magnesium intake is also linked to reduced anxiety symptoms.
  • Herbal Teas (Iced): Opt for caffeine-free herbal teas served over ice. Chamomile, lavender, and peppermint teas are well-known for their calming and soothing properties. Chamomile contains apigenin, an antioxidant that binds to receptors in the brain to reduce anxiety. Peppermint is also known for its cooling effect and ability to relieve tension headaches associated with stress.
  • Fruit and Herb-Infused Water: If plain water seems boring, adding fruits and herbs can make it more appealing. Ingredients like cucumber, mint, and lemon can add a refreshing twist. Mint has a well-documented cooling effect, while cucumber provides additional hydration. This encourages consistent sipping, which is key to maintaining hydration levels.
  • Buttermilk (Chaas): A traditional Indian beverage, buttermilk is made from curd and water with spices like mint and cumin. It is rich in probiotics and helps to cool the body and aid digestion, which is often affected by stress.
  • Green Smoothies: Blending leafy greens like spinach or kale with fruits like bananas can create a stress-busting drink. Spinach is rich in magnesium, which helps regulate cortisol, and bananas provide potassium and Vitamin B6, which are crucial for serotonin production. Blended with a liquid base like almond milk or coconut water, this offers a nutritious and calming boost.

What to Avoid When You Are Stressed in the Heat

Just as important as knowing what to drink is knowing what to avoid. Certain beverages can intensify stress and dehydrate you further, counteracting any cooling effects.

  • Alcohol: Despite the initial relaxing feeling, alcohol is a diuretic that increases urination, worsening dehydration. The rebound effect can increase anxiety and disrupt sleep.
  • High-Caffeine Beverages: Energy drinks, highly caffeinated coffee, and some teas can stimulate the nervous system and raise heart rate, mimicking and intensifying anxiety symptoms. The effects are more pronounced when the body is already under physical stress from heat.
  • Sugary Drinks: Sodas, sugary juices, and other sweetened beverages can cause a blood sugar spike and crash, leading to mood swings and increased irritability. They also add unnecessary calories.

How Your Body Handles Heat and Hydration

Proper hydration is critical for thermoregulation, the process by which your body maintains its core temperature. When you get hot, your body sweats to release heat through evaporation. If you don't drink enough, your blood volume can decrease, making your heart work harder to circulate blood and cool your body. Dehydration also impairs cognitive function, leading to reduced concentration and mental fatigue, which in turn elevates stress. This highlights the need for a deliberate approach to fluid intake when battling heat and stress simultaneously. Keeping a water bottle with you and sipping consistently throughout the day, even before you feel thirsty, is a simple but effective strategy.

Create Your Own Calming Heat-Buster

Here is a simple recipe to create your own stress-relieving, cooling drink:

Cucumber-Mint Refresher

  • 1 liter of cold water
  • 1/2 cucumber, thinly sliced
  • 10-12 fresh mint leaves
  • 1/2 lemon or lime, sliced

Combine all ingredients in a large pitcher or bottle and let it infuse in the refrigerator for at least an hour. This provides a clean, cooling, and hydrating beverage that calms both the body and mind without any added sugar or caffeine. For an extra mineral boost, a pinch of sea salt can be added.

Conclusion

When facing the combined assault of heat and stress, selecting the right beverages is a simple, yet highly effective strategy. Choosing natural, hydrating, and calming drinks like coconut water, iced herbal teas, and infused waters helps to manage the body’s physiological response to both stressors. By avoiding dehydrating and stimulating drinks like alcohol and high-caffeine beverages, you can support your body's natural cooling processes and prevent heightened anxiety. The link between hydration and emotional resilience is well-documented, proving that what you drink can significantly influence how you feel. Making mindful beverage choices is a key step towards feeling more composed and comfortable, even on the hottest and most stressful days.

Stay Calm and Cool with These Soothing Drinks

Frequently Asked Questions

High temperatures put extra physical strain on the body, increasing heart rate and sweat production. This physical stress, combined with psychological stress, can lead to higher cortisol levels and worsen feelings of anxiety and fatigue.

While water is fundamental, a 2025 study showed that poor hydration intensified the stress response. For prolonged sweating, adding an electrolyte drink like coconut water can be more beneficial to replenish lost minerals effectively.

Cortisol is the body’s main stress hormone. When you are dehydrated, your body releases more cortisol in response to stress. Staying adequately hydrated helps regulate these hormone levels, supporting a more stable mood.

Herbal teas are caffeine-free and have soothing properties. Chamomile, lavender, and peppermint are excellent choices. Chamomile and lavender have known calming effects, while peppermint can help relieve tension headaches.

For situations involving prolonged sweating, a balanced sports drink can help replenish lost electrolytes. However, for general heat stress, natural alternatives like coconut water or infused water might be healthier choices with lower sugar content.

Yes, milk contains tryptophan, which helps produce serotonin, a neurotransmitter that promotes feelings of well-being. A warm glass of milk can be particularly soothing for stress.

Alcohol is a diuretic, which causes increased fluid loss and can worsen dehydration. It can also increase anxiety during its rebound effect and disrupt sleep, making it counterproductive for both heat and stress management.
