AB AT-A-GLANCESkin  is  important  for  maintaining  core  body  temperature  within  a  narrow  physiologic  range.Cold  weather,  wind,  humidity,  dampness,  and  altitude  combine  to  inflict  skin  damage.Freezing  and  nonfreezing  conditions  can  both  produce  cold  injuries.Frostbite  occurs  after  exposure  to  intensely  cold  air,  liquids,  or  metals.  Several  degrees  of  frostbite  are  recognized.Self-inflicted  freeze  injuries  from  inhalant  abuse  and  peer  challenges  are  emerging.Winter  xerosis  and  acrocyanosis  are  common  consequences  of  prolonged  exposure  to  cold.Pernio  is  an  acral  eruption  of  edematous  violaceous  papules  occurring  in  cool  rather  than  freezing  exposures,  and  seen  more  frequently  in  lean  persons.Cold  urticaria  is  rare  and  occurs  at  the  sites  of  localized  cooling.Cold  panniculitis  typically  occurs  on  legs  and  cheeks.
