Tips for how to stay safe in the cold
As the National Weather Service warns:
Arctic air, together with brisk winds, can lead to dangerously cold wind chill values. People exposed to extreme cold are susceptible to frostbite in a matter of minutes. Areas most prone to frostbite are uncovered skin and the extremities, such as hands and feet.
Watch for signs of frostbite and hypothermia, and check on neighbors, friends and family members who live alone:
If your temperature is 96°F or less, you feel cold and sluggish, or are having trouble thinking clearly, see your doctor immediately or go to the nearest emergency room.

And if you have to be outside for any length of time, "dress like an onion, so it's all about layers," Clare Arentzen, an Appalachian Mountain Club guide in New Hampshire's White Mountains, told NPR's Life Kit.
The National Weather Service urges anyone who must be outside to cover all exposed skin and stay out of the wind whenever possible.
