Actually, I apologize that was a huge presumption.
When _I_ am in a sauna I'm normally not fully clothed and running around in a stress induced panic.
Also 60 degrees Celsius would mean it made an appearance here:

Given that the highest recorded air temperature on earth is 56.7 degrees, you may wish to revise your last sentence.
I was thinking 40 degrees. Given "average" isn't implied by "really hot", I'd say your 40 degree figure falls in line with what I had in mind. But you're right that it's still a big jump to 60 degrees.
Maybe I shouldn't have put vague comparisons in my post because it's rather distracting from the core point that the GP got their Celsius and Fahrenheit mixed up.

But it seems like 175F (80C) would be a normal-ish range. temperature.
Probably people die in saunas all the time in countries where it's popular, like they sometimes do when eating, walking, or sleeping or watching tv.
80 degrees C would generally be the hotter end of spectrum. Some go as low as 40 degrees C
When outside temperature is equal or higher than body temperature the only way to expel heat is through sweating. For this the air must by dry enough (wet bulb temperature less than body temperature). https://en.wikipedia.org/wiki/Wet-bulb_temperature
If body can't expel enough heat it results in eventual death.
No Celsius. Admittedly 140 C is very hot (but not unheard of) for a sauna and you should probably not be in for more than 2-3 minutes max at a time. 90-110 C however is pretty standard and really nice. I can highly recommend giving it a try.

Given someone died at 110 degrees C in a world championship, I'd wager 140 isn't "hot but not unheard of" and 110 isn't "pretty standard" like you claimed.
