WHAT YOU NEED TO KNOW:
Heat exhaustion is when your body overheats. Normally, the body has a cooling system that is controlled by the brain. The cooling system adjusts to hot conditions and lowers your body temperature by producing sweat. With heat exhaustion, the body's cooling system is not working well and results in an increased body temperature.
Call 911 for any of the following:
- You have trouble breathing.
- You are confused or cannot think clearly.
- You cannot move your arms and legs.
Seek care immediately if:
- You cannot stop vomiting.
Contact your healthcare provider if:
- Your signs and symptoms do not improve with treatment.
- You have numbness or prickling feeling in your arms or legs.
- You have questions or concerns about your condition or care.
First aid for heat exhaustion:
- Move to an air-conditioned location or a cool, shady area and lie down. Raise your legs above the level of your heart.
- Drink cold liquid, such as water or a sports drink.
- Mist yourself with cold water or pour cool water on your head, neck, and clothes.
- Loosen or remove as many clothes as possible.
- If you do not feel better in 1 hour, go to the emergency department.
Prevent heat exhaustion:
- Wear lightweight, loose, and light-colored clothing.
- Protect your head and neck with a hat or umbrella when you are outdoors.
- Drink lots of water or sports drinks. Avoid alcohol.
- Eat salty foods, such as salted crackers, and salted pretzels.
- Limit your activities during the hottest time of the day. This is usually late morning through early afternoon.
- Use air conditioners or fans and have enough proper ventilation. If there is no air conditioning available, keep your windows open so air can circulate.
