Heatwave Survival Guide: What to Eat, Drink, and Avoid in Extreme Temperatures

With temperatures soaring across many parts of India, staying safe during a heatwave has become a serious health priority. Extreme heat can lead to dehydration, heat exhaustion, and even heatstroke, especially in vulnerable groups like children, elderly individuals, and outdoor workers. The Meteorological Department has forecast an early heatwave this week with maximum temperatures of 41°C across North India, especially the national capital, New Delhi. Doctors have flagged health risks - particularly for children, the elderly, and those with chronic illnesses. "The minimum temperatures will be near normal (-1.5°C to 1.5°C) at most places, and the maximum temperature will be above normal (1.6°C to 3.0°C) at most places over Delhi," IMD said,

Why are heatwaves dangerous?

A heatwave occurs when temperatures rise significantly above normal, putting stress on the body’s cooling system. When the body cannot regulate its temperature, it can lead to serious conditions such as heatstroke, a medical emergency. Common warning signs include dizziness, excessive sweating, fatigue, nausea, and headaches. Immediate action is essential to prevent complications.

What to eat during a heatwave?

According to experts, it is important to eat the right foods as they help maintain hydration and energy levels. Also, you must focus on light, water-rich, and easily digestible foods, which replenish fluids and prevent dehydration while keeping your body cool. A few of these include:

Fruits with high water content

Go on for summer special fruits like watermelon, muskmelon, oranges, and papaya

Vegetables

The markets are flooded with cucumbers, lettuce, tomatoes, and zucchini

Curd and yogurt

Both of these help cool your body and support gut health as they are probiotics

Eat light meals

Eat foods like khichdi, dal, and steamed vegetables

Electrolyte-rich foods

Consume more bananas and coconut water

What to drink to stay hydrated?

Hydration is the cornerstone of heatwave survival. Experts recommend:

• Drink water at regular intervals, even if you are not thirsty
• Coconut water is a natural electrolyte that helps restore lost minerals
• Buttermilk or chaas is a traditional cooling drink loaded with probiotics
• Lemon water or nimbu pani is a refreshing beverage that is rich in vitamin C
• Oral rehydration solutions, or ORS, are extremely useful in extreme heat

Doctors recommend avoiding waiting until you feel thirsty, as by then, dehydration may already be underway.

What to avoid in extreme heat?

According to experts, certain foods and drinks can worsen dehydration or increase body heat, including:

• Caffeinated beverages like coffee and energy drinks
• Alcohol leads to extreme fluid loss and dehydration
• Fried and spicy foods increase body temperature
• Sugary drinks and sodas dehydrate further
• Heavy and oily meals are harder to digest in the heat

Reducing these can significantly improve your body’s ability to cope with high temperatures.

Additional safety tips

To prevent getting heatstroke or falling ill due to extreme temperatures, make sure to follow a few safety tips, which include:

• Stay indoors during peak hours (12 PM – 4 PM)
• Wear loose, light-coloured cotton clothes
• Use hats, sunglasses, and sunscreen outdoors
• Take frequent breaks if working outside
• Keep your home cool with fans, curtains, or ventilation

A heatwave survival guide is not just about comfort but also about protecting your health. By choosing the right foods, staying hydrated, and avoiding heat-triggering habits, you can reduce the risk of serious heat-related illnesses. As temperatures continue to rise, small daily choices - what you eat and drink - can have a big impact on your well-being. Stay cool, stay hydrated, and stay safe.
