Summer Heat Wave

A heat advisory or warning has been issued. Now what do you do?

Before Exposure

Stay indoors and avoid extreme temperature changes. If your home does not have air conditioning, go to a shopping mall or public library -- even a few hours spent in air conditioning can help your body stay cooler when you go back into the heat.
If air conditioning is not available, stay on the lowest floor out of the sunshine.
Keep your electric fans running to circulate air.
Drink cool liquids often, particularly water, even if you do not feel thirsty, to help your body stay cool. Avoid alcoholic beverages, which dehydrate the body. During heavy exercise in a hot environment, drink two to four glasses (16-32 ounces) of cool fluids each hour.
Eat small, frequent meals. Avoid foods that are high in protein, which increase metabolic heat.
Keep pets indoors; refill their water bowls frequently.

During Exposure

If you must go out, wear lightweight, light-colored clothing to reflect the sun's energy.
Slow down, avoid strenuous outdoor activity. If you must engage in strenuous activity, limit exposure during mid-day hours.
Cover all exposed skin with a high SPF sunscreen, and wear a wide-brimmed hat to protect your face and head.
Drink plenty of fluids.
Never leave infants, children, or pets in a parked car.

After Exposure

Continue drinking plenty of water.
Never take a cool shower immediately after becoming overheated. You may cool too quickly and become ill, nauseous, or dizzy.
Know the symptoms of heat disorders and overexposure to the sun, and be ready to give first aid treatment.
