saunas feel good, especialy in the winter, and the local indiginious population swear by the use of traditional sweat lodges, the inuit also build sauna shacks , but forget what they call them, but up there you would only need to step outside to get your pores to snap shut, no need for a pool the migimach people have two types of "sweats" one is just a sauna, the other is for cerimonial purposes
