/ˈsaʊnə/

A sauna is a small room or house designed as a place to experience dry or wet heat sessions.

A sauna session can be a social affair in which the participants disrobe and sit or recline in temperatures typically between 158 °F and 212 °F. This induces relaxation and promotes sweating.

And then you have a potluck and talk about farms and chickens and bears and airplanes and communes and movies about communes
