Signs of heat exhaustion include cool, moist, pale or flushed skin; heavy sweating; headache; nausea or vomiting; dizziness; exhaustion. Body temperature will be near normal.
Signs of heat stroke include hot, red skin; changes in consciousness; rapid, weak pulse; rapid, shallow breathing. Body temperature can be as high as 105 degrees. If the person was sweating from heavy work or exercise, skin may be wet; otherwise, it will feel dry.
If signs of heat exhaustion appear:
* Get the person out of the heat. Remove or loosen tight clothing, and apply cool, wet clothes, towels or sheets.
* If the person is conscious, give cool water to drink. Make sure the person drinks slowly (about half a glass every 15 minutes). Do not give liquids that contain alcohol or caffeine.
* Let the victim rest in a comfortable position, and watch carefully for changes in his or her condition.
If signs of heat stroke appear:
* Call 911 or your local emergency number immediately. Heat stroke is a life-threatening situation. Help is needed fast.
* Move the person to a cooler place.
* Immerse the victim in a cool bath, or wrap wet sheets around the body and fan it.
* Watch for signs of breathing problems. Keep the person lying down and continue to cool the body any way you can.
* If the victim refuses water, is vomiting or shows changes in the level of consciousness, do not give anything to eat or drink.
