How To Stay Safe In The Heat

If someone has signs of heat-related illness, move the person to a cool, shaded area and call 911.

Put cold, wet compresses on the person if possible.

Heat stroke, the most serious heat-related illness, can be fatal if not treated immediately.

It occurs when the body's temperature rises rapidly and the sweating mechanism fails, leading to overheating without a way to cool down.

Symptoms include confusion; slurred speech; seizures; hot, dry skin or extreme sweating; altered mental status; very high body temperature; and loss of consciousness/coma.

Here are several ways to stay safe during the heat advisory period:

Lighten up. Wear lightweight, light-colored clothing. Light colors reflect away some of the sun's energy. It is also a good idea to wear hats or to use an umbrella.

Drink water. Carry water or juice with you and drink continuously even if you don't feel thirsty. Avoid alcohol and caffeine, which dehydrate the body. Avoid salt tablets unless directed by a physician.

Eat small meals and eat more often. Avoid high-protein foods, which increase metabolic heat.

Slow down. Avoid strenuous activity. If you must do strenuous activity, do it during the coolest part of the day, which is usually in the morning between 4 and 7 a.m.

Stay inside. If air-conditioning is not available, go to the lowest floor out of the sunshine. Remember that electric fans do not cool; they simply circulate the air.

Be a good neighbor. During heat waves, check in on elderly residents in your neighborhood and those who do not have air conditioning.
