Stay indoors and, if at all possible, stay in an air-conditioned place.
Don’t leave babies, children, or pets in cars, not even for a short time. Heat can kill quickly.
Drink more fluids. If your doctor has limited your fluid intake or if you’re taking “water pills” (diuretics), check with your doctor first.
Don’t drink liquids containing alcohol or lots of sugar. Those drinks may make you lose more body fluid.
Avoid very cold drinks, which can cause stomach cramps.
If you sweat heavily, you may need to replace salt and minerals. A sports beverage may help, but if you’re on a low-salt diet, talk with your doctor before drinking sports drinks or taking salt tablets.
If you have to be outside, try to limit your outdoor activity to morning and evening hours, and try to rest in shady areas.
If you must go outside, wear sunscreen, a wide-brimmed hat, and eyeglasses.
Use a buddy system if you’re working in the heat. Look out for your co-workers and have someone do the same for you.
Check up on high-risk people, including kids, senior citizens, and people who are ill. Visit at-risk adults at least twice daily. Babies and kids need much more frequent checks.
Provide your pets with plenty of fresh water in a shady area.
