Heat Exhaustion

Exercising in the heat can put you at risk for heat-related illnesses. Heat illness occurs when the body cannot sufficiently cool itself. In extreme temperatures or high humidity, your body’s normal cooling system (sweating) may not be enough.

Heat Cramps are muscle pain or spasms in the arms, legs, or abdomen, often caused by a low salt level.

Heat Exhaustion may involve fatigue, dizziness, headache, and nausea. It is generally caused by prolonged heat exposure, dehydration, and loss of salt.

Heat cramps and heat exhaustion are considered milder heat-related illnesses. To treat:

  • Stop activity and rest, preferably in a cool or air-conditioned place.
  • Drink clear juices or sports drinks to replenish electrolytes.
  • Take a cool bath or shower.
  • Seek medical treatment if symptoms worsen or last longer than one hour.
