Extreme Heat Preparedness Tips

Extreme Heat

Extreme Heat often results in the highest number of annual deaths among all weather-related hazards. In most of the United States, extreme heat is defined as a long period (2 to 3 days) of high heat and humidity with temperatures above 90 degrees. In extreme heat, evaporation is slowed and the body must work extra hard to maintain a normal temperature. This can lead to death by overworking the human body. Remember that:

  • 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.
IF YOU ARE UNDER AN EXTREME HEAT WARNING:
  • Find air conditioning.
  • Avoid strenuous activities.
  • Watch for heat illness.
  • Wear light clothing.
  • Check on family members and neighbors.
  • Drink plenty of fluids.
  • Watch for heat cramps, heat exhaustion, and heat stroke.
  • Never leave people or pets in a closed car.
HOW TO STAY SAFE WHEN EXTREME HEAT THREATENS

Prepare NOW

  • Find places in your community where you can go to get cool.
  • Keep your home cool by doing the following:
    • 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 attic fans to clear hot air.
    • Install window air conditioners and insulate around them.
  • Learn to recognize the signs of heat-related illness.
