What Causes Heat-Related Illnesses?

Heat illnesses occur when your body can no longer effectively regulate its temperature. This is most often due to:

• Prolonged exposure to high temperatures

• Physical exertion in the heat

• Dehydration and electrolyte loss

• Wearing restrictive or heat-trapping clothing

1. Heat Cramps

Heat cramps are often the earliest warning sign that your body is struggling with the heat. These painful muscle spasms typically occur in the legs or abdomen and result from heavy sweating and loss of salt and fluids.

Signs & Symptoms:

• Muscle cramps or spasms (usually legs or stomach)

• Body temp up to ~100.4°F (38°C)

• Normal or slightly elevated temperature

Treatment:

• Rest in a cool place

• Rehydrate with electrolyte drinks or water and salty snacks (pretzels, nuts)

• Stretch and gently massage the cramping muscles

2. Heat Exhaustion

Heat exhaustion occurs after prolonged exposure to high temperatures, particularly with physical exertion. It’s more severe than heat cramps and can progress quickly to heat stroke if not treated.

Signs & Symptoms:

• Heavy sweating

• Pale, damp skin

• Headache, nausea, vomiting

• Dizziness, fatigue, irritability

• Temperature between 100.4°F – 104°F (38°C – 40°C)

Treatment:

• Move to an air-conditioned or shaded area

• Loosen clothing

• Apply cool compresses or take a cool bath/shower

• Rehydrate with fluids and electrolytes

• Avoid further heat exposure for the day

3. Heat Stroke

Heat stroke is the most serious form of heat illness and a medical emergency. It occurs when the body can no longer regulate temperature and stops sweating, leading to dangerously high internal temps.

Signs & Symptoms:

• Body temp above 104°F (40°C)

• Hot, dry, flushed skin

• Confusion, agitation, delirium

• Loss of consciousness or seizures

Treatment:

• Call 911 immediately

• Begin aggressive cooling: cold water immersion, ice packs on neck/armpits/groin

• Use misting or fans if immersion is not available

• Continue until emergency responders arrive

How to Prevent Heat-Related Illness

Staying safe in hot weather means planning ahead:

Drink water regularly, even if you’re not thirsty
Avoid alcohol and caffeine during prolonged heat exposure
Wear lightweight, light-colored clothing
Schedule outdoor activities for cooler parts of the day
Take breaks in the shade or air conditioning
Use fans or cooling towels when outdoors
