The brain carries a temperature regulator that keeps the body near a healthy 98°F. But prolonged exposure to extreme heat may overwhelm this natural thermostat.
Intense heat may cause excessive fluid loss through sweating (heat exhaustion). If the body isn’t cooled, sweating eventually stops, but the body’s temperature may keep rising until vital organs begin to fail (heat stroke).
Move the victim into shade and sponge with cool water. Cool head, neck, groin, and underarms.
Remove excess clothing.
Place the victim on his or her back. Elevate feet about 12 inches to lessen the risk of shock.
Monitor the victim every 15 minutes—continue to cool as needed.
Provide the victim with clear liquids if he or she is alert. Offer cool or room-temperature
water. A bottled sports drink is another good choice.
DON’T offer drinks containing milk, which may cause nausea.
The victim is sweating heavily, but the skin feels cool and clammy.
The victim feels dizzy, lightheaded, or weak.
Skin that feels hot and dry to the touch
Drowsiness, disorientation, or loss of consciousness
Loss of muscle control
Reassure the person.
Keep the person as cool as possible.
Treat for shock or provide rescue breathing or CPR, if needed.
