Stay indoors as much as possible and limit exposure to the sun.
Stay on the lowest floor out of the sunshine if air conditioning is not available.
Consider spending the warmest part of the day in public buildings such as libraries, schools, movie theaters, shopping malls, and other community facilities. Circulating air can cool the body by increasing the perspiration rate of evaporation.
Eat well-balanced, light, and regular meals. Avoid using salt tablets unless directed to do so by a physician.
Drink plenty of water. Persons who have epilepsy or heart, kidney, or liver disease; are on fluid-restricted diets; or have a problem with fluid retention should consult a doctor before increasing liquid intake.
Limit intake of alcoholic beverages.
Dress in loose-fitting, lightweight, and light-colored clothes that cover as much skin as possible.
Protect face and head by wearing a wide-brimmed hat.
