Heat Injury

When the weather is very hot and humid, it is a good idea to avoid exercising in order to prevent heat injury. In optimal weather conditions, sweating cools your body. But if high humidity prevents sweat from evaporating, your body cannot cool itself properly. Continuing to exercise produces more and more sweat, and dehydration can quickly occur, especially if you aren't drinking enough fluids.

Loss of consciousness and coma can soon follow. Warning: Heat stroke is a medical emergency. Call 911 or your local emergency number and request an ambulance. While you wait for medical help to arrive, lie down in a cool place and have someone place cool, wet cloths on your skin or ice packs under your armpits and at the wrists and the groin area.

Remember to drink plenty of fluids whenever you exercise, but especially in hot, humid weather. Try to work out indoors when the heat or the humidity rises, or skip your exercise routine until the weather turns cooler.
