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
- WDGPublicHealth on Twitter or Facebook
- News items posted to our Public Health homepage
Have a plan
Plan breaks from the heat by spending a few hours in a cool place. It could be a tree-shaded area or an air-conditioned spot such as a shopping mall, grocery store, community or recreation centre, place of worship or public library.
Remember that children, the elderly and those with chronic conditions are at a higher risk of suffering from heat-related illness.
During times of high heat and humidity:
- Stay hydrated by drinking plenty of water or juice
- Stay out of the sun
- At home, close awnings, curtains and blinds during the day to keep the sun out
- Schedule strenuous outdoor activities for the early morning or evening hours
- Spend as much time as possible in air-conditioned places
- Never leave people or pets inside a parked vehicle or in direct sunlight
- Plan to visit or call neighbours, friends and family, especially isolated seniors, to make sure they’re cool and hydrated
- If you have air conditioning, welcome family and neighbours into your home when they need a place to cool off
