Emergency room doctor Jeffrey Sather says when it gets this cold, frostbite does become a possibility.
"You know, people will put on a pair of gloves. They'll get damp. They'll start to have tingling in their fingers. They'll ignore that to the point that they actually will have some freeze injury to their skin," says Sather.
"Freeze burn is much like a hot burn. It causes damage to the skin. It will blister and the skin will peel off just like if you burn your hand with heat."
With prolonged exposure, the risk moves to hypothermia, where one's core body temperature actually drops and can lead to confusion, unconsciousness and even death.
