Many people prefer this type over the electrically heated one. The third type is a smoke sauna . It has a huge wood burning heater, and smoke from the burning wood is let out into the sauna. Before the sauna is used, the smoke is let out through a small vent. While this type of sauna is becoming rare, it can still be found.
T here are many customs related to the Finnish sauna.
Before entering the sauna, it is polite to take a quick shower. Also, if provided, use a little towel to sit on the sauna's bench. It is usually the host who pours the water on the hot heater rocks to generate steam. The person pouring the water is responsible for adjusting the amount of water, so that everyone in the sauna can enjoy it. Sometimes beer is also poured on the rocks to fill the sauna with the aroma of baked bread.
