Athletes are especially prone to heat illness such as heat stroke and heat exhaustion, especially if they are unfamiliar with the warning signs. Heat illness can be life threatening if not taken seriously. Most serious heat illness in athletes can be prevented by following these basic guidelines and heeding the warning signs and symptoms.
There are three major types of heat illness, each with specific symptoms and treatments.
Heat cramps are a type of heat injury that usually occurs after strenuous exercise or an outdoor activity. Symptoms of heat cramps are severe pain and cramps in the legs and abdomen, faintness or dizziness, weakness, and profuse sweating.
Heat exhaustion happens when one is exposed to heat for a prolonged period of time. The body may become overwhelmed by heat when its mechanism (sweating) for keeping cool breaks down. Symptoms of heat exhaustion include nausea, dizziness, weakness, headache, pale and moist skin, weak pulse, and disorientation.
Heat stroke, unlike heat exhaustion, strikes suddenly and with little warning. When the body's cooling system fails, the body's temperature rises quickly. Heat stroke can be life threatening! Signs of heat stroke include very high body temperature, hot, dry skin, lack of sweating, fast pulse, confusion, and possible loss of consciousness.
