<human>:  What is the difference between a banya and a sauna?
<bot>: A sauna is a dry heat bath. A banya is a wet heat bath. A banya is a traditional Russian bath. A banya is a small room heated by wood fire, which is covered with a wooden dome. The dome is removed to expose the room to the elements. The room is then filled with steam. The heat is generated by the wood fire, and the steam helps to create the humidity.
