Heat stroke is a medical emergency, and recognizing it early can save your life.

The key is knowing the warning signs and taking fast, effective action to cool the body.

How to Identify Heat Stroke

Heat stroke happens when your core body temperature rises to 40°C (104°F) or higher, and/or when your body can no longer cool itself.

Symptoms escalate quickly and often include:

Very high body temperature (40°C), Hot, red, dry skin (no sweating in classic heat stroke), Rapid heartbeat and fast breathing

Confusion, agitation, slurred speech

Irritability or delirium, Seizures or loss of consciousness, Nausea or vomiting, Headache or dizziness

These neurological symptoms are especially important. They distinguish heat stroke from milder heat exhaustion

What to Do Immediately (First Aid)

If you suspect heat stroke, call emergency services right away. While waiting for help:

Move the person to shade or a cool indoor area, remove excess clothing, and cool the body aggressively: Apply cold, wet towels or ice packs to the neck, armpits, and groin

Spray or sponge with cool water while fanning. If possible, immerse in cool water (bath, shower), If unconscious, place in the recovery position and monitor breathing; cooling within 30 minutes dramatically improves outcomes.

How to Protect Yourself from Heat Stroke

Heat stroke is preventable. To stay safe, especially in hot climates, follow these steps:

Hydration and Lifestyle

Drink plenty of water regularly; don’t wait until you’re thirsty

Avoid alcohol and very sugary drinks; they worsen dehydration

Take extra care if you’re on medications that affect sweating or hydration (e.g., diuretics, beta-blockers, antidepressants)

Clothing and Sun Protection: wear loose, light-colored clothing, use broad-spectrum sunscreen (SPF ≥15), wear a wide-brimmed hat and sunglasses

Activity Planning

Avoid strenuous activity during 11:00–15:00, the hottest hours

Take frequent breaks in shade or air‑conditioned spaces. Gradually acclimate to heat over several days if temperatures rise suddenly

Home Safety

Keep indoor spaces cool: close curtains, use fans, and rely on air conditioning when possible. Never leave children, pets, or vulnerable adults in parked cars, even briefly

High‑Risk Groups

Extra caution is needed for older adults.  Young children. People with heart, lung, or metabolic conditions. Anyone not accustomed to high heat. Tell us what you think
