With these dangerously cold temperatures we're experiencing, there is a very real risk of frostbite. A high pressure ridge is pushing in frigid Arctic air and we're seeing wind chills dip into the -30's almost every night. There isn't much reprieve during the day either. 

Amanda Prysizney with Environment Canada says once the wind chill dips down that low, any exposed skin can contract frostbite quickly.

"We get into the higher risk we get into the -28 to -39 range. I think that's probably why they picked the -28 wind chill factor for cancelling outdoor recess," Prysizney said. "That's the higher risk and exposed skin can freeze in 10 to 30 minutes. It depends where you are in that range, but it can happen very quickly."

Frostbite can be extreme in some cases, but it can also just cause pain, numbing and irritation in more minor cases. The symptoms of frostbite are cold and stiff skin or burning, tingling, stinging or a numbing sensation on the damaged area. 

The operational meteorologist says thanks to the harsh winds over the province, proper winter attire is a must when heading outside, even for just a brief period of time. 

"We do need a wind of about 50 kilometers an hour, so the wind does come into play a lot with frostbite," Prysizney said. "With these cold temperatures, people need to dress according, even if you're just walking to the bus or walking to school. Keep an eye on the temperature and the windchill, and dress accordingly, or stay indoors."

With the wind chill expected to hit -39° tonight, staying indoors may just be your best option. If you do head outdoors in that temperature, be sure to be bundled up and avoid extended periods of time in the cold.
