Extreme heat causes more deaths than any other kind of weather, according to Ready.gov, FEMA's preparedness site. It happens when temperatures climb above 90°F for several days with a lot of humidity. The body then has to work extra hard to stay cool, which is dangerous if you are not careful. The page is Ready.gov's extreme heat guide for young readers; it explains the terms in a heat forecast and what to do.
Words to know
| Term | Meaning | What to do |
|---|---|---|
| Heat wave | A period of unusually hot weather, typically two or more days. It must be unusual for the area: a few 95-degree summer days in Houston, Texas, may not count because summers there are usually warm, but the same days in Maine, usually cooler, might | |
| Extreme heat watch | Issued when extreme heat is possible | Plan to cancel outdoor activities and follow the weather on TV or radio. Without air conditioning, locate the nearest cool place or arrange to stay with family or friends who have it |
| Extreme heat warning | Issued when extremely dangerous heat is expected or already happening | Avoid outdoor activities, especially in the heat of the day. If you must be out, drink plenty of water and take frequent breaks in the shade. Stay in an air-conditioned space as much as possible, including overnight, check on family and neighbors and bring pets inside |
| Heat advisory | Issued when it will be hot, but not as hot as in extreme heat | Consider postponing outdoor activities, especially during the hottest part of the day, drink plenty of water, take breaks in the shade and stay somewhere cool |
| Humidity | How much water vapor is in the air | When it is hot and the air is humid, you feel uncomfortable because sweat cannot evaporate |
Am I at risk?
Where you live matters. In a place that does not usually have several days in a row at 90 degrees or higher, a few days of high heat and humidity count as extreme heat. It makes your body work extra hard to keep a normal temperature, which can make you very sick.
Before
- Learn the signs of heat illness, such as feeling sick, muscle cramps, weakness or dizziness. If you or a friend has them, go somewhere cool, drink water and rest, and tell an adult right away.
- Find places in the community where you can get cool, such as a library, shopping mall or community center, and ask the local health department about cooling options.
During
- Drink plenty of water, and take cool showers or baths.
- Wear loose, lightweight, light-colored clothing and a hat wide enough to protect your face.
- Never leave people or pets in a car on a warm day.
- Keep window blinds and shades closed to keep the heat out, and find shade if you are outside.
- Avoid playing outside or doing sports in the midday heat.
- Check on family, friends and neighbors, especially older adults and people who spend most of their time alone at home.
- Watch for heat illness and tell an adult right away if you or someone you know feels sick.
- Keep pets safe: outdoors they need plenty of cool water and comfortable shade, and asphalt and dark pavement can be very hot for their feet.
