the reason people get hot and strip is actually cause by the body core temp dropping to low.
When in the cold, severe cold, the body will slow down blood to the arms and legs, to try and maintain your core temp. Its a natural reaction of the body trying to survive. However once your core drops to a certain temp where it can no longer function, the body gives way, all the blood rushes to the arms and legs and people feel like they are suddenly on fire from the warm blood. And once that happens people think they are alright when in fact they are minutes away from dying.
Bottom line, don't mess with the severe cold, it will and can kill you.
