Prevent Heat-Related Illness

Extreme Heat Safety

Be Prepared. Stay Informed.

Extreme heat is a period (at least 2-3 days) of high heat and humidity with temperatures above 90 degrees. In extreme heat your body works extra hard to maintain a normal temperature, which can be dangerous.

Heat-related illness can affect anyone. Those most at risk are adults 65+, young children, outdoor workers, people with chronic conditions, people on certain medications, and those who without A/C.


Prepare for Extreme Heat

  • Learn the signs and symptoms of heat related illness.
  • Identify local cooling centers.
  • Cover your windows with drapes or shades.
  • Weather-strip doors and windows.
  • Use a powered attic ventilator, or attic fan, to regulate the heat level of a building's attic by clearing out hot air.

Be Safe During Extreme Heat

  • Drink plenty of fluids
  • Wear light, loose fitting clothing
  • Never leave people or pets in a closed car
  • Avoid strenuous activities
  • Watch for heat-related illness
  • Check on family members and neighbors

*Call 9-1-1 and seek immediate medical attention if heat related symptoms worsen or last longer than one hour.
