If you or anyone else has symptoms of heat exhaustion, it's essential to immediately get out of the heat and rest, preferably in an air-conditioned environment. If you can't get inside, try to find the nearest cool and shady place.
Other recommended strategies include:
Drink plenty of non-caffeinated and non-alcoholic beverages.
Remove any tight or unnecessary clothing.
Take a cool shower, bath, or sponge bath.
Apply other active cooling measures such as fans or ice towels.
If such measures fail to provide relief within 30 minutes, contact a doctor because untreated heat exhaustion can progress to heat stroke.
After you've recovered from heat exhaustion, you'll probably be more sensitive to high temperatures during the following week. So it's best to avoid hot weather and heavy exercise until your doctor tells you that it's safe to resume your normal activities.
