Protect yourself during extended extreme heat warning

Aug 24, 2021
SIMCOE COUNTY– An extreme heat warning has been issued for some communities in our region for Aug. 24 to 25.

SIMCOE COUNTY– An extreme heat warning has been issued for some communities in our region for Aug. 24 to 25, a reminder that people should be careful of their health and look for ways to avoid overheating, says the Simcoe Muskoka District Health Unit. Presently these areas include:

  • Midland - Coldwater - Orr Lake
  • Orillia - Lagoon City - Washago
  • Barrie - Collingwood - Hillsdale

An existing heat warning for the following areas has been extended for today and possibly into the middle of this week:

  • Innisfil - New Tecumseth - Angus

When temperatures are high, overexertion will increase the risk of heat exhaustion, dehydration or heat stroke.

During the heat, you should be taking care to avoid overheating.

  • Be sure to drink plenty of fluids (non-caffeinated). Don’t wait until you feel thirsty – that’s a sign that your body is already becoming dehydrated.
  • Stay cool indoors.
  • If you must be outside, stay in the shade and make sure you wear and reapply sunscreen, a broad-brimmed hat, sunglasses and lightweight, light-colored, loose-fitting clothing.
  • Electric fans provide comfort by increasing evaporation, however when conditions are extreme, fans will not prevent heat-related illness.
  • Keep physical activity to a minimum.
  • Draw blinds or curtains to prevent radiant heat from entering homes.

Infants and young children, the frail elderly and people with chronic lung conditions or taking certain prescription drugs are more vulnerable to harm from overheating. Check in on these people to make sure they’re staying safe.
