- High humidity. When the humidity is high, sweat won’t evaporate as quickly, which keeps your body from releasing heat as fast as it may need to.
- Personal factors. Age, obesity, fever, dehydration, heart disease, mental illness, poor circulation, sunburn, and prescription drug and alcohol use can play a role in whether a person can cool off enough in very hot weather.
- People who are at highest risk are the elderly, the very young, and people with mental illness and chronic diseases
- But even young and healthy people can get sick from the heat if they participate in strenuous physical activities during hot weather.
Air-conditioning is the number one protective factoragainst heat-related illness and death. If a home is not air-conditioned, people can reduce their risk for heat-related illness by spending time in public facilities that are air-conditioned.
Here’s what you can do to prevent heat-related illnesses, injuries, and deaths during hot weather:
- Stay in an air-conditioned indoor location
- Drink plenty of fluids.
- Wear loose, lightweight, light-colored clothing and sunscreen.
- Schedule outdoor activities carefully.
- Pace yourself.
- Take cool showers or baths to cool down.
- Check on a friend or neighbor and have someone do the same for you.
- Do not leave children in cars.
- Check the local news for health and safety updates.
