How To Prevent Heat Stroke And Heat Exhaustion: Stay Healthy In The Heat

A country like India can face extreme weather conditions, including high temperatures during summer. Heatwaves have become quite common throughout the country, and as temperatures rise, the possibility of heat stroke and heat exhaustion also increases. It is essential to know that such conditions can impact anyone, including students, office workers, outdoor workers, senior citizens, and even healthy adults. However, you can prevent heat-related illnesses with just a few simple precautions. 

What Is Heat Stroke And Heat Exhaustion?

Heat exhaustion occurs when your body loses excessive amounts of water and electrolytes, such as sodium and potassium, due to sweating. It causes weakness, dizziness, headaches, pale skin, and nausea. This is an early warning sign that your body is overheating.

On the other hand, heat stroke is a serious medical emergency. Your body temperature rises above 40°C, leading to symptoms such as confusion, a rapid heartbeat, red skin, or fainting. Heat stroke can damage organs if not treated immediately and requires urgent medical help.

Cause of a Heat Stroke 

India’s extreme climate, characterised by long summers, high humidity, and frequent heatwaves, increases the risk of heat-related illnesses. Outdoor workers, children, older adults, pregnant women, people with chronic health conditions, and those who travel long distances in peak heat are at higher risk.

How To Prevent Heat Stroke And Heat Exhaustion?

Below are simple and routine practices to know how to prevent heat stroke and stay safe even in intense heat.

  1. Drink Enough Water Throughout The Day: Hydration is the most effective way to prevent heat stroke. Drink water regularly—even if you’re not thirsty. Add electrolyte drinks for heat, such as ORS, nimbu paani, coconut water, chaas, aam panna, and fresh juices to maintain your electrolyte levels. Avoid alcohol and excessive tea/coffee, as they cause dehydration.
  1. Wear Light, Breathable, And Loose Clothes: Cotton and linen clothes allow airflow and help your body stay cool. Choose light colours, such as white, beige, or pastels, as they reflect heat rather than absorbing it.
  1. Avoid Stepping Out During Peak Heat Hours: The sun is strongest between 12:00 PM and 4:00 PM. Try to schedule outdoor work in the morning or evening. If unavoidable, take frequent breaks, walk in shade, and avoid prolonged exposure.
  1. Protect Your Head And Skin: Use umbrellas, scarves, caps, or hats to protect yourself from the sun. Apply SPF 30+ sunscreen if you’re outdoors for more than 20 minutes. Sunburn can raise body heat and increase the risk of heat exhaustion.
  1. Eat Fresh, Light, and Cooling Foods: Fruits like watermelon, muskmelon, papaya, cucumber, grapes, and oranges are excellent sources of hydration. Include curd, buttermilk, salads, and home-cooked meals. Avoid spicy, oily, or hefty meals that increase internal heat.
  1. Avoid Overexertion And Heavy Exercise: Intense physical activities, workouts, and outdoor sports during hot weather can lead to heat stroke. Choose indoor exercises or a workout early in the morning.
