When the body is unable to cool itself through sweating, serious heat
illnesses may occur. The most severe heat-induced illnesses are heat
exhaustion and heat stroke. If actions are not taken to treat heat
exhaustion, the illness could progress to heat stroke and possible
death.
HEAT EXHAUSTION:
WHAT HAPPENS TO THE BODY: Headaches, dizziness/light headedness,
weakness, mood changes (irritability or confusion), nausea, vomiting,
decreased and dark colored urine, fainting, and pale clammy skin.
WHAT SHOULD BE DONE:
- Move the person to a cool shaded area to rest. Don't leave the
person alone. If the person is dizzy, lay them on their back and
raise their legs about 6-8 inches. If the person is sick to their
stomach, lay them on their side.
- Loosen and remove any heavy clothing.
- Have the person drink some cool water (small cup every 15 minutes)
- Try to cool the person by fanning them. Cool the skin with a cool
spray mist of water or wet cloth.
- If the person does not feel better in a few minutes, call for help
(ambulance or 911).
