Extreme heat is a period of high heat and humidity with temperatures above 90 degrees for at least two to three days.
- Extreme heat can occur quickly and without warning.
- Older adults, children and sick or overweight individuals are at greater risk from extreme heat.
- Humidity increases the feeling of heat as measured by a heat index.
Find places in your community where you can go to get cool.
- Cover windows with drapes or shades.
- Weather-strip doors and windows.
- Use window reflectors such as aluminum foil-covered cardboard to reflect heat back outside.
- Add insulation to keep the heat out.
- Use a powered attic ventilator, or attic fan, to regulate the heat level of a building’s attic by clearing hot air.
- Install window air conditioners and insulate around them.
BE SAFE DURING
- Never leave a child, adult, or animal alone inside a vehicle on a warm day.
- Find places with air conditioning. Libraries, shopping malls, and community centers can provide a cool place to take a break from the heat.
- If you’re outside, find shade. Wear a hat wide enough to protect your face.
- Wear loose, lightweight, light-colored clothing.
- Drink plenty of fluids to stay hydrated. If you or someone you care for is on a special diet, ask a doctor what would be best.
- Do not use electric fans when the temperature outside is more than 95 degrees. You could increase the risk of heat-related illness. Fans create air flow and a false sense of comfort, but do not reduce body temperature.
- Avoid high-energy activities.
- Check yourself, family members, and neighbors for signs of heat-related illness.
