Finnish-style saunas are often confused with “wet” saunas because of the
water that is sprinkled on the rocks to make steam and increase
humidity, however, the amount of water used is not enough to make steam
that hangs in the air, as in the case of the traditional ‘Turkish Steam
Bath’. It dissipates very quickly and serves to aid in the transferrance
of heat and to increases humidity to about 30% to aid in perspiration.
