Huh, this made me curious about saunas and how they're survivable if they're that hot, since I've never been in one myself. Apparently the air inside saunas is very dry (making sweating very effective), even though they're traditionally pictured as being steamy? Would I be right in saying there's very little air movement in one, as well? I'm guessing there's a lot of boundary layer type effects going on.
Edit: The Wikipedia entry's description makes no sense. The hottest saunas have low humidity levels produced by pouring water on hot stones? And the people in the sauna are below the dew point and so have condensation forming on them rather than evaporating? How then do they shed the heat?
