Heat stroke is a life-threatening emergency where the body overheats and can no longer cool itself. In India’s summers it is common — rapid cooling while help is on the way saves lives.
1. Call emergency services — heat stroke is life-threatening.
2. Move the person to a cool, shaded or air-conditioned place.
3. Remove excess clothing.
4. Cool aggressively: wet the skin, fan them, and place cold packs on the neck, armpits and groin.
5. If fully conscious, give small sips of cool water or ORS.
6. Keep cooling until help arrives or the temperature comes down.
When to see a doctor urgently
Warning signs: very hot skin, confusion, no sweating, fainting, seizures, rapid pulse
Do NOT give fluids to someone who is drowsy or unconscious (choking risk)
Heat stroke differs from heat exhaustion — it involves confusion and a very high temperature
Cool first, cool fast. Every minute of delay in cooling increases the danger. Aggressive cooling plus emergency care is the treatment. This is not a substitute for emergency care. Call your local emergency number.
Frequently asked questions
What is the difference between heat exhaustion and heat stroke?
Heat exhaustion causes heavy sweating, weakness and nausea but a clear mind; heat stroke adds confusion, a very high temperature and sometimes no sweating — and is a life-threatening emergency.
How do I cool someone with heat stroke?
Move them to shade, remove clothes, wet the skin and fan them, and put cold packs on the neck, armpits and groin. Call emergency services.
Should I give water?
Only small sips if they are fully awake. Never give fluids to a drowsy or unconscious person because of choking risk.
