Heat exhaustion commonly occurs while working or exercising outdoors in hot and humid weather. Under these conditions, the body often cannot cool itself off quickly enough. Symptoms of heat exhaustion may include excessive sweating, nausea, headache, cramps, and dizziness. While heat exhaustion is most common in the elderly and very young, it can happen to anybody. Try to avoid situations where heat exhaustion could occur. If you do develop any of these symptoms, seek shelter in a cool place and drink plenty of fluids. You should also seek medical attention, as heat exhaustion could lead to heat stroke, a potentially life-threatening illness.
