 Slow down on heater and hotter parts of the day. Stay hydrated. Drink plenty of water. Spend as much time indoors as you can. Postpone your activities. And always treat your symptoms. See how you feel yourself. And if you feel weird, just tell somebody. If you feel that you are dizzy, if you feel that you have muscle pains or spasm, you can have a heat cramp. So tell someone that you're not feeling well.
