The heat warning issued for Tuesday through Thursday by Environment Canada means that people should be taking care not to overdo it, the health unit says.

When temperatures stay at or above 31° C for more than a day and night-time temperatures stay above 20° C or the humidity index exceeds 40° C, over-exertion will increase the risk of heat exhaustion, dehydration or heat stroke.

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 with these people to make sure they’re staying safe.

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 and if possible, seek out an air-conditioned place.
  • If you must be outside, stay in the shade and make sure you apply sunscreen and wear a broad-brimmed hat, sunglasses and lightweight, light-coloured, loose-fitting clothing.
  • Electric fans provide comfort by increasing evaporation, however when the conditions are extreme, fans will not prevent heat-related illness.
  • Keep physical activity to a minimum.
  • Draw blinds/curtains to prevent radiant heat from entering homes.

For more information about extreme heat, visit the health unit’s website at www.simcoemuskokahealth.org, or call Health Connection at 721-7520 (1-877-721-7520) Monday to Friday, 8:30 a.m. to 6 p.m.
