Heatstroke symptoms call for emergency care

Many parts of the U.S. have hit dangerously high temperatures this week, but no matter where you are, know the symptoms and treatment for heat-related illnesses.

Heatstroke occurs when body temperature rises rapidly and you’re unable to cool down. It can be lifethreatening, damaging your brain and other organs. It may be caused by strenuous activity in the heat or being in a hot place for too long.

Heatstroke signs and symptoms include:

Fever of 104 degrees or greater

Changes in mental status or behavior, such as confusion, agitation or slurred speech

Hot, dry skin or heavy sweating Nausea and vomiting Flushed skin Rapid pulse Rapid breathing Headache Fainting, which may be the first sign in older adults

If you suspect heatstroke, call 911 or your local emergency number. Then, immediately move the person out of the heat, and cool him or her by whatever means available. For example:

Put the person in a cool tub of water or a cool shower.

Spray with a garden hose.

Sponge with cool water.

Fan while misting with cool water.

Place ice packs or cool wet towels on the neck, armpits and groin.

Cover with cool damp sheets.

Let the person drink cool water or other nonalcoholic beverage without caffeine, if he or she is able.

Begin CPR if the person loses consciousness and shows no signs of circulation, such as breathing, coughing or movement.
