I grew up in a very cold, snowy climate, where Winter lasted an average of five-and-a-half months. One way we got through the Winter comfortably was by taking lots of long saunas. I delighted in sitting in the very hot sauna until I couldn't stand it any longer, and then jumping out the door to roll in the snow outside. When I visit my family every Winter, I always revive the tradition.
