Environment and Climate Change Canada has forecast daytime highs of 31, feeling like the low 40s, extending through to Wednesday in Simcoe County. Night time temperatures will not provide much relief.

When temperatures stay at 31° C or higher for more than a day, or the humidity index exceeds 40° C, 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 and if possible, seek out an air-conditioned place.
• 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 the 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.

Extreme heat over several days increases the health risks for vulnerable people. Keep an eye on infants and young children, the frail elderly and people with chronic lung conditions or taking certain prescription drugs, as they are more vulnerable to harm from overheating.
