10 Effective Ways to Protect Yourself from Heat Waves in India
India’s summers are getting hotter. Heat waves are no longer a rare occurrence but a dangerous seasonal norm, with temperatures soaring above 45 degrees Celsius in many parts of the country, from Delhi and Jaipur to Nagpur and Patna. In recent years, rising global temperatures and urban heat island effects have made these scorching events even more intense, putting millions of people at risk of heatstroke, dehydration, and even death.
A heat wave isn't just about discomfort, it's a serious health threat. Understanding what it is, why it's happening more often, and how to stay safe is now more important than ever.
1. Stay Hydrated Throughout the Day
Why it matters: Sweat is water on its way out, and when it leaves, your brain starts begging for a refill. Dizziness, fatigue, even a full-blown heat stroke can show up before you say why me.
What to do:
Aim for 3 to 4 litres even if you dont feel thirsty.
Skip the cola and whiskey; they wave goodbye to your fluids.
ORS, coconut water, or good old lemonade bring back the lost salts.
A sturdy water bottle is your new pocket buddy whenever you step outside.
2. Avoid Going Out During Peak Hours (12 PM – 4 PM)
Why it matters: The sun is at its harshest during this time, increasing the risk of heat exhaustion and sunburn.
What to do:
Plan outdoor activities during early morning or late evening.
If unavoidable, use umbrellas, hats, and cooling scarves.
Take frequent breaks in the shade if you're outdoors.
3. Wear Light, Loose, and Breathable Clothing
Why it matters: Tight or synthetic clothes trap heat and sweat, leading to discomfort and skin rashes.
What to do:
Choose cotton or linen fabrics in light colors.
Avoid dark colors as they absorb heat.
Wear full sleeves to protect your skin from direct sunlight.
4. Keep Your Home Cool
Why it matters: High indoor temperatures can be just as dangerous as being outside.
What to do:
Close curtains or use heat-reflective blinds.
Switch off lights and appliances when not in use.
Use ceiling fans with water-cooled air (DIY air coolers or wet curtains).
Consider planting greenery around your home to reduce heat absorption.
5. Use Sunscreen to Protect Your Skin
Why it matters: Prolonged exposure to UV rays increases the risk of sunburn and skin cancer.
What to do:
Use a sunscreen with SPF 30 or higher.
Reapply every 2–3 hours, especially if sweating.
Don’t forget exposed areas like neck, ears, and feet.
6. Eat Light and Seasonal Foods
Why it matters: Heavy or spicy meals generate internal heat and cause indigestion.
What to do:
Eat more fruits like watermelon, cucumber, and musk melon.
Include buttermilk, curd, and salads in your meals.
Avoid fried or oily foods during extreme heat.
7. Keep a Cool Cloth Handy
Why it matters: Applying a cool cloth on your neck, forehead, or wrists can instantly lower body temperature.
What to do:
Dip a clean cloth in cold water and place it on pressure points.
Use it after returning from outdoors.
Store a few wet wipes or cloths in your fridge for quick relief.
8. Avoid Crowded and Poorly Ventilated Areas
Why it matters: Enclosed and packed spaces trap heat and reduce oxygen, increasing the risk of suffocation and fatigue.
What to do:
Prefer open-air transport or AC buses/trains if traveling.
Avoid crowded markets during daytime.
Ventilate your room with cross-breezes or fans.
9. Be Aware of Heatwave Alerts
Why it matters: The Indian Meteorological Department (IMD) regularly issues heatwave warnings.
What to do:
Follow weather apps and government alerts.
Reschedule events or travel plans based on the forecast.
Educate your family members, especially the elderly and kids.
10. Take Care of Vulnerable Groups
Why it matters: Infants, elderly people, and those with health conditions are at higher risk during heat waves.
What to do:
Check on neighbors, elders, and pets.
Ensure they stay hydrated and cool.
Never leave children or animals in parked vehicles.
