Most common are smoke saunas. It is a room with a pile of rocks, with no chimney. A fire is lit directly under the rocks, then fire is put out, and the heat stored in the room and in the rocks is the heat source. The smoke-sauna stove is also used with a sealed stone compartment and chimney (a heat storage-stove) which eliminates the smoke odour and eye irritation of the smoke sauna. There are also infrared saunas use a special heater that generates infrared radiation rays similar to that produced by the sun. A continuous fire stove, instead of stored heat, is a recent invention. There is a firebox and a smokestack, and stones are placed in a compartment directly above the firebox. It takes shorter time to heat than the heat storage-sauna, about 1 hour. A fire-heated sauna requires manual labor in the form of maintaining the fire during bathing; the fire is also a hazard. Similar, but electrically heated saunas are often used in homes.
