The sauna, a religion in Finland: 3.3 million for 5.5 million inhabitants. In saunas, deals are closed, friendships are forged and family ties are cemented.

Kotiharjun Sauna, opened in 1928 in the old working-class neighborhood of Kallio, is today the bohemian place par excellence. All Sea Pool, in the heart of Helsinki, offers a toning session after a swim in the outdoor pool with water from the Baltic Sea.
