HEAT CRAMPS

Heat cramps are muscular pains and spasms that usually occur in the legs or abdomen caused by exposure to high heat and humidity and loss of fluids and electrolytes. Heat cramps are often an early sign that the body is having trouble with the heat. If someone is experiencing heat cramps:

• Get the person to a cooler place and have him or her rest in a comfortable position. Stretching, massaging and icing the affected muscle may help.

• Give a half glass of cool water or a sports drink with electrolytes every 15 minutes. Do not give liquids with alcohol or caffeine in them, as they can make conditions worse.

HEAT EXHAUSTION

Heat exhaustion is caused by a combination of exercise induced heat and fluid and electrolyte loss from sweating. Signs of heat exhaustion include cool, moist, pale or flushed skin; heavy sweating; headache; nausea; dizziness; weakness; and exhaustion. To help someone with these symptoms:

• Move the person to a cooler place. Remove or loosen tight clothing. Spray him or her with water or apply cool, wet cloths or towels to the skin. Fan the person. If the person is conscious, give small amounts of cool water cool water or a sports drink with electrolytes to drink. Make sure the person drinks slowly. Watch for changes in his or her condition.

• If the person refuses water, vomits or begins to lose consciousness, call 9-1-1 or the local emergency number.
