First of all, it is good to be aware of the distinction between the steam and sauna bath. Most people think of the heat of a sauna as dry heat and the heat of a steam room as wet, humid heat. This distinction is only partially correct. Sauna bathers in Finland splash water on the heated stones in the sauna, raising the humidity level to as much as 40%. Without that, the hot, dry sauna air can irritate the mucus membranes. A Sauna is a Finnish style sweat bath, usually consisting of a room constructed of soft wood, containing a stove which is used to heat the room to about 180 degrees Fahrenheit. And steam bath is fed with a steam generator which produces thick clouds of mist.
