Normally, when you get hot, your body cools itself by sweating. But when it is very hot and humid, sweating just isn't enough. In such cases, a person's body temperature rises rapidly. Very high body temperatures may damage the brain or other vital organs and even cause death. Symptoms of Heat-Related Illnesses
Anyone can experience heat-related illness. Some people, like people who work outdoors, older adults, people with underlying health conditions, and small children, are more at risk during heat waves. It is important to check on older family members and neighbors.
What You Should Do
Check on friends, family, and neighbors during extreme heat. Encourage them to stay cool at home by using air conditioners or other cooling methods – or to go somewhere that has air conditioning.
Drink plenty of fluids (avoid alcohol and caffeine).
Never leave a child, a disabled person, an older adult, or a pet in an unattended car. A closed vehicle can heat up to dangerous levels in as little as ten minutes.
Ask your doctor for heat advice. Don’t stop taking medication unless your doctor says you should.
Seek medical attention immediately for anyone showing signs of heat stroke.
When Outside
Stay out of the direct sun. Seek shaded areas or air-conditioned areas indoors.
Provide plenty of fresh water for your pets and leave the water in a shady area.
Slow down and limit physical activity.
Schedule outdoor events early in the morning when it's cooler.
If an air quality alert is also declared, try to avoid physical activity outside in the afternoon.
Wear light-colored, light-weight clothing. Use hats with brims and sunscreen (SPF 30 or more) for more protection.
When Inside
If your home does not have air conditioning, you should open windows, use fans, and keep shades or curtains drawn the during the day.
Take cool showers or baths.
When it is cooler than 95°F, open windows on opposite sides of the home, then use an electric fan to pull cool air into the living space and a second fan to blow hot air out. This creates a cross-breeze.
Avoid cooking in the oven or stovetop indoors during the day when it’s hottest.
Unplug large electronics, such as televisions, that produce heat.
At-Risk Populations
Infants and young children are sensitive to extreme heat and rely on other people to keep them cool and hydrated.
Adults age 65 and older are less likely to sense and respond to changes in temperature.
People who have underlying health conditions may be less likely to sense and respond to changes in temperature. They may also be taking medications that make them more sensitive to extreme heat.
Athletes are more likely to become dehydrated and are more likely to get heat-related illness.
People who work outside are more likely to become dehydrated and are more likely to get heat-related illness.
People who have low income may be unaware of cooling centers and may have limited access to other cooling protections.
