Sauna rooms are small buildings designed for people to enter and experience heat sessions with temperatures reaching over 176 degrees Fahrenheit or 80 degrees Celsius.
There are two styles of saunas. They are conventional, which only warms the air, and infrared, which warms objects. Carbon fiber and charcoal are used to heat the area for infrared.
Sauna rooms were first used as living quarters in the wintertime. They were just pits that were dug in slopes in the ground. They included a fireplace with stones that were kept hot. The temperature was raised by throwing water over the rocks, which produced steam. These early winter saunas would get hot enough that the people could remove their clothing. The first wooden built sauna was in Finland in about the 5th century.
Today modern sauna rooms can be found in public gyms and sports centers in Russia, Western Europe, and North America. They can be found in homes for a person’s private session. Public swimming pools may also have saunas with a designated area for removing swimwear.
The smoke sauna is the earliest form of a Finland sauna. It is an outdoor sauna building. The building has a pile of rocks for heating the room, but it has no chimney. The temperature in this sauna room only reaches 60 degrees, but the humidity is very high. This outdoor sauna is still being used today, although the tradition for these steam baths almost died out.
A stove for smoke sauna rooms stops the odor of smoke with a chimney and a compartment for sealed stone with an insulated lid. Because of these sauna designs, this steam bath does not give up much heat, but the heat is very clean. The stones in the sauna stove will glow red to white hot, which frees them from dust.
There are two types of continuous heat sauna rooms. The most common is the electric stove type, used primarily in urban areas. Elements keep the stones heated with a thermostat and timer on the electric stove. The other type is continuous fire. A constant fire is held inside a firebox with rocks directly above it in a compartment. It takes only an hour to heat the sauna with this method, but it takes manual labor to keep the fire constantly burning. Using continuous fire is a new invention.
