Understanding Heat Stroke
Heat stroke is more than just being overheated—it’s a medical emergency. Unlike heat exhaustion, which can often be managed at home, heat stroke can lead to brain, heart, and kidney damage if not treated quickly.
When your body loses the ability to regulate its temperature, and your core temperature rises above 40°C (104°F), you’re in dangerous territory.
Why it’s dangerous:
- Can cause organ failure and brain swelling
- Leads to severe dehydration and cardiac stress
- May result in death if not treated promptly
High-risk groups include:
- Seniors
- Children and infants
- Patients with heart disease or hypertension
- Outdoor workers, athletes, and travelers exposed to extreme heat
Early Warning Signs to Watch For
Be alert to these symptoms—early recognition can save lives. Here’s a quick checklist:
- Headache or lightheadedness
- Hot, dry skin (no sweating)
- Rapid pulse or heart palpitations
- Nausea or vomiting
- Confusion or slurred speech
- Fainting or loss of consciousness
If someone is experiencing multiple symptoms, act immediately.
What to Do Immediately
While waiting for help or heading to the ER, here’s what you can do:
- Move the person to a cooler, shaded area
- Hydrate only if they are awake and alert
- Apply cool compresses to the neck, armpits, and groin
- Use a fan or wet towels to lower body temperature
Don’t delay professional care. Moderate to severe heat stroke requires emergency medical attention—home treatment may not be enough.
When to Go to the Emergency Room
Go to the ER immediately if you or someone else experiences:
- Altered mental state (confusion, agitation, seizures)
- Unconsciousness or fainting
- Persistent high fever
- Rapid heartbeat with chest pain or shortness of breath
Heat stroke can trigger cardiac complications, especially for seniors or those with pre-existing heart conditions.

Prevention Tips
The best way to fight heat stroke? Avoid it altogether.
- Stay hydrated – Drink water regularly, not just when you feel thirsty
- Avoid direct sun exposure from 10 AM to 4 PM
- Wear light, breathable clothing
- Use umbrellas, hats, and sunglasses
- Take breaks in cool, shaded, or air-conditioned areas
Prevention is especially crucial during summer months or heatwaves.
