Found out when those highs of -40 during the day and -90s at night, it was interesting to survive. Found out that over dressing your feet or winter gear, you could easily freeze from the inside out since you sweat inside your coverings. Always best to be a wee bit chilly when you start out as you will build up body heat with activity. Also very careful of static electricity with the dryness. We always had to zap ourselves around the standing aircraft in hangars with leaking fuel from teh aircraft. Pans were always catching the fuel. Also coming back from the various clubs depending on rank, could not help as it lowers body heat with excessive liquids for medicinal purposes. (YUK YUK!!) Found a couple of guys that did not make it back with severe frostbite. Took a while to get use to it with the help of good room mates and fellow workers.
