That was a wonderful read, thanks for sharing. I moved from the UK to Finland and fell in love with saunas on first contact. As is well-known there is basically a sauna for everyone in the country here. When I first arrived we lived in a building that contained about 20 flats/apartments, and there was an external building on the grounds which contained the communal sauna. Every Monday evening any man living in the building could go use it, and similarly every Tuesday there was a ladies night. On top of that you could pay a small monthly fee to book the sauna for your exclusive use for 1-2 hours on a regular schedule (e.g. "7-8pm, every Saturday"). Those communal saunas were awesome. Meeting, relaxing, and talking to your neighbours whilst drinking beer for 60-120 minutes. With breaks outside in the cold air, and regular showers. These days I live alone and I have a sauna inside my flat. I gain from being able to turn it on whenever I want, but lose because it is smaller than the communal ones - I can have three people in mine at a time, and I do invite friends, partners, and other random people over. But the communal ones had space for 8-16 people. (Maybe 10 people inside at a time, and a bit of regular rotation where some people would leave, and some new folk enter). Anyway I'm rambling, but I'd never really paused to consider the "science" or planning behind different design choices. I've seen a bunch of saunas here, from the small one I currently have, to one built by a friend's grandfather on their private island, just outside Helsinki. Wooden saunas are amazing, and definitely going from being in one of those to jumping naked in a lake is one of the best experiences I've been able to have regularly. But even my small and basic on makes me content and happy.
