Drink plenty of liquids. Drink eight or more 8-ounce glasses per day of water and/or fruit juices every day to stay hydrated.
Avoid caffeinated and alcoholic beverages. Alcohol, soda, coffee and even tea can leave you dehydrated quickly. If at all possible, try to reduce the amount of these beverages, especially during hot weather. Plain or flavored water is a good substitute.
Dress appropriately. Wear loose-fitting clothes in natural fabrics like cotton. Dress in light colors that will reflect the sun and heat instead of darker colors that will attract them.
Sunblock. When outdoors, protect your skin from damage by wearing hats, sunglasses and a sunscreen of SPF 30 or higher.
Stay indoors during extreme heat. In extreme heat and high humidity, evaporation is slowed and the body must work extra hard to maintain a normal temperature.
Air conditioning. If you do not have air conditioning in your home, go somewhere that does. A movie theater, the mall a friend or relative's home or a community senior center are all good options.
Avoid extreme outdoor heat. If you need to get out of the house and don't drive , call a taxi, a friend or a transportation service. Do NOT wait outside for the bus in extreme heat.
Take a cool shower or bath. If you are absolutely unable to leave the house and do not have air conditioning, take a cool bath or shower to lower your body temperature on extremely hot days.
Keep your home cool. Temperatures inside the home should not exceed 85 degrees Fahrenheit for prolonged periods of time.
Signs of heat stroke. Know the signs of heat stroke (e.g. flushed face, high body temperature, headache, nausea, rapid pulse, dizziness and confusion) and take immediate action if you feel them coming on.
