Heat Cramps

These cramps, in which arm or leg muscles go into spasms, occur when excessive sweating causes electrolyte (salt) loss. Have a sports drink. Stretch and massage to relieve pain.

Heat Exhaustion

Marked by headache, dizziness, and nausea, this heat-induced health problem strikes when you are dehydrated and can’t keep your core temperature down. Hydrate as above. Apply cool, damp cloths to the face and body. Stand in front of a fan or an air conditioner.

Heat Stroke

Striking when your body’s cooling system shuts down, heat strokes cause confusion, fainting, seizures, or coma. Call 911; cool as above or sit in an ice bath.
