INCREASED RISK OF HEAT ILLNESSES

Environment Canada is warning residents that the risks brought on by heat are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.

“Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion,” the agency says.

They advise drinking plenty of water, checking in on family and friends, never leaving people or pets inside vehicles, and taking regular breaks if working or exercising outdoors.
