Ontario’s Heat Wave: Take Care

Extreme Heat Expected To Last Most of the Week

Dr. Arlene King, Ontario's Chief Medical Officer of Health, is warning that heat puts stress on everyone. During a heat wave, please take special care to prevent heat-related illness.

Those on the ends of the age spectrum – infants and seniors over 65, - and those with chronic medical conditions or taking medications are most at risk, but anyone can be affected. Heat-related illnesses occur when the body is unable to properly cool. Ontarians need to pay attention to heat alerts issued by local public health units.

To prevent heat-related illness, try these helpful tips:

Drink plenty of water or natural fruit juices
Wear light, loose fitting clothes, a hat and sunscreen when outdoors
Eat light, cool foods, and don’t use the oven or other hot appliances
Stay in air conditioned rooms - either at home, a friend's place or public spaces such as malls, libraries, or specially designated facilities in the community
Choose to exercise in the early morning or late evening when it's cooler
Check up regularly on those who may be at high risk during a heat wave.
