I disagree with everyone in this thread so far based on my own experience.
Had every watch from the OG to the latest Ultra 2, upgrading every year. Worn every single one in a hot dry sauna and my own personal home steam room. Not one issue ever. I always have AppleCare+ on them though. I also wear my AirPods in those environments. Never issues either.
I workout 4-6 days a week and use a sauna or steam room every time. Never had a single issue with any watch. YMMV but that’s my experience.
