Take Steps to Prevent Heat-Related Illnesses

With temperatures expected to reach into the 90s and the heat index peaking between 95 and 105 degrees at times this summer, state health officials are encouraging residents to take steps to prevent heat-related illnesses.

“Extreme heat can contribute to serious health issues and we want people to know that options like shopping malls and libraries are available to help you stay cool, especially if you do not have air conditioning at home,” said Karen McKeown, State Health Officer.

Residents are asked to check on family, friends and neighbors who may be isolated or are elderly to ensure they are taking steps to prevent heat-related illnesses. Also, children, disabled individuals, or pets should never be left in parked cars, even briefly.

To stay safe, residents are encouraged to:

  • Slow down and limit physical activity outdoors.
  • Drink plenty of water and eat lightly.
  • Wear lightweight, loose-fitting, light-colored clothing.
  • Never stop taking medication unless your doctor says you should.
  • Take a cool shower or bath to cool down.
