Woah, that seems like a lot for me. I can usually stand maybe 60ºC for like 10 maybe 15 min. I don't think I'd be able to stand 30 min under 73ºC.

73°C is a bit unusual cold for a Finnish sauna. Wikipedia says:
> The temperature in Finnish saunas is 80 to 110 °C (176 to 230 °F), usually 80–90 °C (176–194 °F)
And with that temperature, I think 10–15 minutes are pretty standard.
This is one of the most famous public saunas in Finland: https://www.kotiharjunsauna.fi/en
If the temperature there is not close to 120°C, we are kind of disappointed.
I was in a 110C sauna for 20 minutes today. Plus 15 minutes in a 70C one (hybrid infrared sauna). Max is 30 minutes at once at 70C. It does take some getting used to.
The sauna at my gym is regularly over 180F and I do 30 minute sessions. It is a dry sauna however, no steam.

Humidity is the key, Finnish style sauna is low humidity+ high temperature (85-115C is OK i think), while Russian banya-style is low temperature (60-80C with high humidity). Both of them produce about the same load on a human
