the only saunas I have been to so far were my room in winter (up to 22.7°Celsius without heating

) and some different places in Morocco (stuff like 50 degrees on a normal day, or still 40 when it was 10pm... The climatized room with only 30 degrees felt incredibly good)
The next poster is living in a country where 40+ degrees are usual (at least some time in the year)
