The frigid temperatures Saturday combined with the punishing wind chill have doctors warning about the risk of frostbite.

Norwalk Hospital's Dr. Christopher Mikos says frostbite occurs when extremities actually freeze.

He says it can happen faster if you have poor circulation or your core body temperature drops with hypothermia, causing blood vessels to constrict and hampering blood flow.

"You want to make sure you have layers on cotton or silk," Mikos says.

To avoid a frostbite emergency Mikos says to "get yourself into a warmer environment, don't vigorously rub, but get yourself into some warm covers or some warm blankets so your extremities don't freeze."
