The combination of high heat, high humidity and exposure to the sun’s ultraviolet (UV) rays can be hazardous to your health. It’s important to prepare for hot weather to help prevent heat-related illness and death.
What can you do to protect yourself and others from extreme heat?
Know the forecast
Prepare ahead of time: be on the lookout for heat warnings. You can find out when there’s a heat warning by following:
- Local weather reports
- Warnings from Environment Canada
Remember that older adults, individuals with chronic conditions, children and infants are at a higher risk of suffering from heat-related illness.
During times of high heat and humidity
- Know and look out for signs of heat illness
- Stay hydrated by drinking plenty of water or juice
- Wear loose-fitting, light-coloured clothing and a wide-brimmed hat made of breathable fabric
- Make meals that do not use the oven
- At home, close awnings, curtains, and blinds during the day to keep the sun out
- Take cool showers or baths
- Avoid strenuous outdoor activities or reschedule for the early morning or evening hours
- Never leave people or pets inside a parked vehicle or in direct sunlight
- Before heading out, check the Air Quality Health Index in your area. Air pollution tends to be at higher levels during very hot days
- Avoid sun exposure
- Call neighbours, friends and family, especially isolated older adults, to make sure they’re cool and hydrated
