Which country of the world has 5 million inhabitants and almost two million saunas?

With a population of around 5.5 million, this Nordic nation boasts an astonishing number of saunas—current estimates place the figure well over two million. This works out to an average of one sauna for every two or three citizens, which is more than enough for the entire population to use one simultaneously. The sauna is not considered a luxury item here but a cultural institution and a near-necessity, as essential to a home as a kitchen or a bedroom.

Far more than just a hot room, the sauna is a cornerstone of social life and well-being. It is a deeply ingrained tradition and a versatile space used for relaxing with family and friends (Review), cleansing the body and mind, and even conducting informal business meetings. Historically, the sterile, warm environment of the sauna served as a place for childbirth and for preparing the deceased for burial, highlighting its central role throughout a person's entire life.

This deep-rooted tradition is found everywhere, from private apartments and lakeside summer cottages to corporate headquarters and the nation's parliament building. The significance of this practice was officially recognized in 2020 when its sauna culture was added to UNESCO's list of Intangible Cultural Heritage, cementing its status as a vital and cherished part of the national identity.
