How to Stay Cool in Extreme Heat: Prevention Tips and Safety Guide

Introduction

What is Body Heat and Why it increases in summer?

When the body temperature rises above normal levels, often due to hot weather, dehydration, spicy food, or illness, it's called body heat. This can cause symptoms such as sweating, fatigue, headache, and skin burning. To regulate body temperature, it's important to drink plenty of water, eat cool foods, and avoid excessive heat.

In summer, the body temperature rises mainly because the body's ability to cool itself by sweating is reduced due to high temperature and humidity. Dehydration, excessive sun exposure, spicy or oily foods, and physical exertion can further increase body temperature. As a result, people may experience sweating, fatigue, headaches, and skin irritation.

Precautions for Stepping Out

When stepping out of the house in extreme heat, what precautions should you take?

During the summer, when it's extremely hot, leaving the house becomes impossible. However, those who do leave the house for work or for essential purposes should keep a few important things in mind to avoid excessive heat and relieve body heat. No one knows when, where, and what will happen to whom at any time after leaving the house during this extreme heat. So let us understand those things which we can know that if it is very hot and we have to go out of the house, then what things should be kept in mind so that we can avoid the intense heat and body heat.

When we go out of the house in this intense heat, we should take proper precautions for our own and others' safety. The main precautions are:

Drink plenty of water to avoid dehydration. If you go out of the house, carry a water bottle, Glucose, and ORS (Oral Rehydration Solution) water with you.

Wear light-colored, soft, and breathable cotton clothes.

Apply sunscreen while going out to protect yourself from harmful sun rays, and wear sunglasses to protect your eyes.

Wear a wet cloth to cover your head, or alternatively, wear a cap and use an umbrella.

Avoid going out of the house during the peak of the afternoon when it is the hottest.

Stay in shady places, like under a tree, to relieve fatigue and avoid the heat. Take a rest if it feels too hot.

If you go out, look for refreshing drinks like lemon water, soft drinks, and Lassi.

Causes & Symptoms of Increased Body Heat

Causes of Increased Body Heat

Generally, there are many internal and external reasons for an increase in body temperature during summer. Hot weather and high humidity reduce our body's ability to cool down through sweating during summer days. Dehydration reduces the body's fluid levels, making it more difficult to regulate temperature. When it comes to diet, spicy food, caffeine, and alcohol can increase body temperature.

Excessive physical exertion or vigorous exercise also increases body temperature. In women, hormonal imbalances, such as during their periods or thyroid issues, can contribute to this. Wearing tight and non-breathable clothing traps heat inside, while frequent stress and a lack of sleep can disrupt the body's temperature balance, leading to excessive heat.

Symptoms of Body Heat

When body heat rises, it can affect different systems and cause noticeable symptoms. Common signs include excessive sweating, dehydration, and a constant feeling of thirst. You may experience fatigue, weakness, dizziness, or headaches.

The skin may become hot, flushed, or irritated, sometimes leading to rashes or prickly heat. Digestive issues like acidity, nausea, or loss of appetite can also occur. In severe cases, people may develop muscle cramps, a rapid heartbeat, or confusion. Dark-colored urine and reduced urination are key signs of dehydration. If body temperature continues to rise, it may progress to heat exhaustion or, in severe cases, heatstroke, which is a medical emergency.

Foods and Drinks to Reduce Body Heat

Foods to Reduce Body Heat

Foods that help reduce body heat are especially useful during hot weather and can keep the body cool, hydrated, and energized. Hydrating fruits like Watermelon, Cucumber, and Muskmelon are rich in water and help lower internal temperature. Coconut water is excellent for replenishing electrolytes and preventing dehydration.

Dairy items like Buttermilk and Yogurt aid digestion and provide a cooling effect. Fresh herbs such as Mint and Coriander also help reduce heat in the body. Light meals like salads, citrus fruits, and soaked seeds (like fennel or chia) further support hydration. To help keep your body cool, minimize the consumption of spicy, oily, and processed foods, which may increase internal heat.

Drinks For Cooling the Body

It is very important to keep our body cool in summer, and consuming fluids in this heat can help in controlling temperature and preventing dehydration. Some great natural beverages include:

Coconut water: This is an excellent natural coolant that helps lower internal body temperature. It is rich in essential electrolytes like potassium, magnesium, and sodium, which quickly restore fluids lost through sweating, prevent dehydration, and soothe the stomach to reduce acidity.

Lemon water: A highly refreshing drink that quickly lowers body temperature. Rich in Vitamin C, it supports immunity, fights heat stress, and works like a natural ORS when mixed with water and a pinch of salt and sugar.

Buttermilk (Chaas): A traditional cooling drink that cools the body from within. Rich in probiotics, it promotes gut health, aids digestion, and helps restore salts lost during perspiration.

Sugarcane juice: This juice helps regulate body temperature, keeps the body hydrated, and provides a quick energy boost through natural sugars without increasinginternal heat.

Aam panna: Made from raw mangoes, this drink has a powerful cooling effect. It is widely known for preventing heatstroke (loo), restoring lost fluids, and reducing acidity or indigestion.

Watermelon juice: Composed of over 90% water, it keeps the body deeply hydrated, acts as an instant coolant, and is very easy to digest.

Cucumber juice: With about 95% water content, it naturally lowers body temperature, detoxifies the system, and keeps the skin hydrated and free from heat-related irritation.

Wood apple juice (Bael fruit): Traditionally used to protect againstextreme heat and "loo," Baeljuice has strong cooling and digestive properties that help resolve heat-related stomach issues.

Mint-based drink (Pudina drink): Mint has natural cooling properties that quickly lower body temperature, soothe digestion, and relieve fatigue caused by hot weather.

Fennel water (Saunf water): Fennel has natural cooling properties that lower internal heat, improve digestion, and flush out toxins from the body.

Home Remedies & Ayurvedic Treatments

Home remedies to Reduce Body Heat

To reduce the heat in your body, you should adopt simple home remedies. These include drinking cooling beverages, consuming natural cooling ingredients like psyllium husk (isabgol) or tragacanth gum (gond katira), eating waste-enriched cooling foods, and taking cool showers.

Ayurvedic Treatments

According to Ayurveda, to reduce body heat, the focus should be on calming and pacifying the Pitta Dosha. For this, you should consume mild and sweet foods like cucumber, coconut water, and mint. Herbs like fennel and aloe vera are highly beneficial.

To reduce stress and physical discomfort caused by excessive heat, you can massage soothing oils like sandalwood or castor oil. It is recommended to make it a habit to take a cool bath in the morning and practice calming activities early in the day.

Key body-cooling foods and herbs in Ayurveda include cucumber, watermelon, grapes, pomegranate, and leafy vegetables. Beneficial herbs and spices include coriander, fennel (shatapushpa), aloe vera (kumari), amla, and mint, along with beverages like coconut water, rose water, and fennel water.

Ayurvedic Lifestyle Tips to Reduce Body Heat:

Daily Habits: Include calming and cooling breathing techniques like Sheetali or Sheetkari Pranayama in your routine.

Natural Cooling Methods: Massage a few drops of cold-pressed castor oil on your navel (nabhi) and the soles of your feet to help balance body heat and soothe inflammation.

Foods to Eat Less Of: Spicy, oily, deep-fried, and fermented foods may increase the sensation of body heat and are best consumed in moderation.

Clothing Choices: Opt for loose, airy fabrics such as cotton or linen in light, soothing colors like white, green, or blue.

Medical Treatment in Severe Conditions

In cases of extreme body heat, especially when heatstroke is suspected, it becomes a medical emergency that needs immediate attention. This condition can be life-threatening and requires rapid cooling of the body. If this occurs, seek immediate emergency medical care. While waiting for help, move the person to a shaded or cooler place, remove excess clothing, and begin cooling methods such as applying ice packs or cold, damp cloths to areas like the neck, underarms, and groin.

Emergency Response for Severe Heat Conditions:

Acting quickly is essential to avoid organ damage or life-threatening complications. If it can be done safely, cold water immersion (placing the person in cold or ice water) is among the most effective methods for rapidly lowering body temperature.

Alternatively, you can use evaporative cooling by lightly spraying the skin with cool water while using a fan, or apply cold compresses/ice packs to areas where major blood vessels are located (neck, underarms, groin, and back). Avoid giving the person anything to drink or medications like aspirin or paracetamol if heatstroke is suspected, as these may worsen the condition.

Hospital Management of Severe Heat Conditions:

Once the patient reaches a medical facility, doctors use advanced treatments to stabilize the condition. This includes giving intravenous (IV) fluids to restore hydration and correct electrolyte imbalances. Special cooling blankets or medical equipment are used to quickly lower body temperature.

Medications may be prescribed to control symptoms like seizures or excessive shivering, which can otherwise interfere with the cooling process. Throughout this, doctors conduct vital organ monitoring to protect the kidneys, heart, and liver from damage.
