Cold weather
Very cold temperatures can pose risks for cold-related injuries, including frostnip (mild frostbite), frostbite, and hypothermia, all of which can be prevented. Additionally, cold weather can worsen existing health conditions, particularly those affecting the heart or lungs. Health risks are highest for people experiencing homelessness, older adults, infants and children, people with pre-existing health conditions such as heart or lung disease, and those who work or enjoy recreation outdoors.
To prevent cold-related injuries and ensure the safety of yourself, your family, and others from the dangers of very cold temperatures:
-
Check the weather – verify conditions before going out. Keep children indoors when it's -27°C or colder (including wind chill).
-
Check on others – ensure friends, family, and neighbors are warm and safe, both indoors and outdoors.
-
Dress appropriately – wear layers, including a hat, gloves, a scarf, warm socks, and waterproof boots.
-
Recognize cold injuries – be aware of frostnip, frostbite, and hypothermia. Monitor vulnerable individuals for symptoms.
-
Stay warm and dry – seek shelter from the cold and take breaks indoors. Change into dry clothing if you get wet, and drink warm beverages (avoid alcohol and caffeine).
-
Travel safely – avoid unnecessary travel. Keep an emergency kit in your vehicle.
For relief from cold temperatures locally, check with your municipality to find available warming spaces near you.
