No, it is not recommended to wear clothes in a sauna. The high temperatures of the sauna (up to 100°C) and the close contact with other people can cause discomfort when wearing clothes. Therefore, most people choose to go nude or wrap themselves in a towel while they are inside. Additionally, wearing clothing could also prevent proper sweating which could reduce the effectiveness of your sauna session and limit its health benefits such as improved circulation and detoxification.
