Norway has a long history of sweat bathing. Their practice, called badstue, wasn’t nearly as ubiquitous as the Finnish sauna, especially in modern times. But recently they have experience a significant increate in interest and practice.
In 2021, Knut Lerhol and Hallgrim Børhus Rogn published a book about the Norweigan sauna scene called Badstufolk. Some of the things they cover are: the recent boom in sauna, the history of sauna in Norway, health benefits, badstue practice, building saunas, and examples of great badstue.
Note: It’s difficult to track down in North America at the time of writing, and it’s written in Norwegian (as you can see).
