What to Do:
If you show signs or symptoms of heatstroke, seek emergency medical care immediately. In cases of heat exhaustion and while awaiting help with possible heatstroke:
- Go indoors or into the shade immediately.
- Get undressed
- Lie down; elevate feet slightly.
- Take a cool (not cold) bath, or sponge bathe repeatedly. If outside, cool down using a garden hose.
- Take frequent sips of cool, clear fluids (clear juices or sports drinks are best).
- If vomiting, turn body to the side to prevent choking.
- Monitor your temperature.
Always drink plenty of fluids before and during any activity in hot, sunny, weather – even if you aren't thirsty. Wear light-colored loose clothing and only participate in heavy activity outdoors before noon or after 6 PM. Go indoors immediately whenever feeling overheated.
