What are heat related illnesses?

Heat related illnesses are the leading cause of extreme weather-related deaths in the United States. It is caused by your body not being able to cool itself. Your body naturally cools down by sweating but if your body heats too fast, it may not be able to cool itself fast enough, causing permanent damage or even death.

The following people have the highest risk of experiencing heat related illness:

  • Children 4 years old and younger
  • Adults 65 years and older
  • People who are overweight

What should I do to prevent illness?

Make sure to check the weather for any heat advisories in your area. Also, the CDC has made the following recommendations for protecting yourself from extreme heat:

  • Stay in an air conditioned area during the hottest parts of the day. If you don't have air-conditioning in your home, go to a public place such as a library or shopping mall to stay cool. Also, check if there are any cooling stations open in your area.
  • Wear light loose-fitting clothing.
  • Drink water often, don't wait until you're thirsty.
  • Avoid unnecessary hard work or activities if you are outside or in a building without air-conditioning.
  • Avoid unnecessary sun exposure. When in the sun, wear a hat, preferably with a wide brim.

Air-conditioning is the strongest protective factor against heat related illness. Exposure to air-conditioning for even a few hours a day will reduce the risk of heat related illness.
