Extreme heat is associated with several health impacts ranging from heat stress to heat stroke or more severe effects, such as cardiovascular-related disease and death. Cooling stations can provide relief and protection for vulnerable populations at an increased risk for heat-related illnesses.
How heat warnings are issued
Environment Canada issues heat warnings when:
- A humidex is 40°C or higher for two consecutive days, or
- The daily temperature is expected to reach 31°C or higher, and overnight temperatures will be at least 20°C or higher for two consecutive days
Protect yourself
The Government of Canada provides publications about extreme heat:
Precautions to take during high heat alerts
- Never leave children or pets alone in a parked car. Temperatures can rise to 52°C (125°F) within 20 minutes in an enclosed vehicle when the outside temperature is 34°C (93°F). Leaving the car windows slightly open or "cracked" will not keep the inside of the vehicle at a safe temperature.
- Check in on family, friends and neighbours, especially those most at risk. Heat stroke is a medical emergency! Learn more about heat illnesses, who is at high risk, and what to do at niagararegion.ca.
- Reschedule or plan outdoor activities during cooler parts of the day
- Rest frequently in shaded areas
- Drink plenty of fluids (unless your physician restricts fluids)
- Dress in cool, loose clothing and shade your head with a hat or umbrella
- Take cool showers or baths until you feel refreshed
