Once the wind chill makes the temperature feel like –28 or colder, exposed skin can freeze in under 30 minutes.
When it drops to –40, frostbite can occur in less than 10 minutes.
Take it to –55, and you're in danger within two minutes.
Anything colder than that and Environment Canada warns you shouldn't go outside at all.
Your body doesn't appreciate being exposed to the cold for too long, so it takes protective action. It puts most of its energy into keeping your core — where your internal organs are located — as warm as possible. Unfortunately, your toes, fingers, cheeks and ears may pay a steep price for keeping the rest of your body toasty.

Frostbite:
Frostbite is, literally, frozen body tissue, usually the skin, but sometimes, deeper tissue and must be handled carefully to prevent permanent tissue damage. Frostbite requires medical attention by a health care provider. Kids are at greater risk for frostbite than adults, both because they lose heat from their skin more rapidly and because they may be reluctant to leave their winter fun to go inside and warm up.
Frostnip
Frostnip is a milder form of injury. It usually affects areas that are exposed to the cold, such as the cheeks, nose, ears, fingers, and toes, leaving them red and numb or tingly. Frostnip can be treated at
home and gets better with rewarming.
Preventing Frostbite and Frostnip:
To help prevent frostbite in cold weather:
Stay updated on weather forecasts. If it's extremely cold, even brief exposure to cold can cause frostbite.
Dress kids in layered warm clothes and use hats, gloves, scarves, thick socks, and well-insulated boots to cover body parts that are most prone to frostbite. Inner clothing layers that absorb moisture and outermost layers that are windproof and waterproof are helpful.
Make sure kids come indoors at regular intervals.
Change kids out of wet clothing or shoes as soon as possible.
