The Finnish sauna is a substantial part of Finnish and Estonian culture.

The culture of Finland combines indigenous heritage, as represented for example by the country's national languages Finnish and Swedish, and the sauna, with common Nordic and European cultural aspects. Because of its history and geographic location, Finland has been influenced by the adjacent areas, various Finnic and Baltic peoples as well as the former dominant powers of Sweden and Russia. Finnish culture is built upon the relatively ascetic environmental realities, traditional livelihoods, and heritage of egalitarianism and the traditionally widespread ideal of self-sufficiency.
