Heat Stroke

Heat stroke occurs when the body becomes unable to control its temperature: the body's temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. Body temperature may rise to 106F or higher within 10-15 minutes. Heat stroke can cause death or permanent disability if emergency treatment is not given.

Recognizing Heat Stroke

Warning signs of heat stroke vary but may include:

an extremely high body temperature (above 103F, orally)
red, hot, and dry skin (no sweating)
rapid, strong pulse
throbbing headache
dizziness
nausea
confusion
unconsciousness
What to Do

If you see any of these signs, you may be dealing with a life threatening emergency. Have someone call for immediate medical assistance while you begin cooling the victim:

Get the victim to a shady area.
Cool the victim rapidly using whatever methods you can. For example, immerse the victim in a tub of cool water; place in a cool shower; spray with cool water from a garden hose; sponge with cool water; or if the humidity is low, wrap the victim in a cool, wet sheet and fan him or her vigorously.
Monitor body temperature, and continue cooling efforts until the body temperature drops to 101-102F.
If emergency medical personnel are delayed, call the hospital emergency room for further instructions.
Do not give the victim alcohol to drink.
Get medical assistance as soon as possible.
Sometimes a victim's muscles will begin to twitch uncontrollably as a result of heat stroke. If this happens, keep the victim from injuring himself, but do not place any object in the mouth and do not give fluids. If there is vomiting, make sure the airway remains open by turning the victim on his or her side.
