Frigid temperatures mean skin that’‘s exposed for too long are prone to frostbite, when affected areas feels rock hard and develops a white, waxy, or purplish appearance.

If you get frostbite, The Nemours Foundation advises you:

  * Seek medical care.
  * Come indoors immediately and remove wet clothing.
  * Treat frozen parts gently; don’‘t rub them.
  * Warm the frozen parts in warm water (not hot) for about 30 minutes. Don’‘t use dry heat, such as a fireplace, to thaw frostbite.
  * Warm your entire body by wrapping yourself in a blanket.
  * Place clean cotton balls between frostbitten fingers and toes after they’‘ve been warmed.
  * Loosely wrap warmed areas with clean bandages to prevent refreezing.
