Heat stroke and heat exhaustion!

Heat stroke and heat exhaustion are both heat-related illnesses but differ in severity and symptoms.

### Heat Exhaustion


- Heavy sweating

- Weakness or fatigue

- Dizziness or fainting

- Nausea or vomiting

- Muscle cramps

- Headache

- Cool, moist skin with goosebumps (in heat stress)


- Prolonged exposure to high temperatures

- Dehydration

- Intense physical activity


1. Move to a cooler place.

2. Drink cool water or sports drinks.

3. Rest.

4. Apply cool, wet cloths to the body.

5. Loosen tight clothing.

### Heat Stroke


- High body temperature (104°F or higher)

- Altered mental state or behavior (confusion, agitation, slurred speech)

- Hot, dry skin or profuse sweating

- Nausea and vomiting

- Flushed skin

- Rapid, shallow breathing

- Racing heart rate

- Headache


- Prolonged exposure to high temperatures

- Strenuous physical activity in hot weather

- Untreated heat exhaustion


1. Call emergency services immediately.

2. Move the person to a cooler environment.

3. Cool the person rapidly using whatever means available (immerse in cool water, ice packs, or cold wet cloths).

4. Do not give fluids if the person is unconscious.

Key Differences:

- Severity: Heat stroke is more severe than heat exhaustion and can be life-threatening.

- Body Temperature: Heat stroke involves a body temperature of 104°F or higher, while heat exhaustion does not.

- Mental State: Heat stroke often causes confusion, agitation, or loss of consciousness, unlike heat exhaustion.

Preventive measures for both conditions include staying hydrated, wearing appropriate clothing, taking breaks in cool environments, and avoiding excessive physical activity in extreme heat.
