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.
