Based on 'True events'?

Probably any of the numerous stories of people dying in saunas and sweat lodges.

The true event is that, in Georgia, where the filmmakers are from, 3 out of 4 kids got stuck in the sauna, one that was outside, had no idea he left them in the sauna, and started searching for them elsewhere. Also the part on how exactly door got locked, the sequence of unfortunate minievents, as it is revealed at the end, is based on true.

In true story, no one died because, the heater was electric, so by removing the rocks they decreased the temperature, but had to be in still hot sauna for over 10 hours.

There's a movie on Netflix about different ways people died by accident, most died by electricity but one couple were in a small home built sauna in their backyard. The door handle broke and they couldn't get out. The husband died and the wife was rescued the next day by neighbors who heard her calling for help.

I'm thinking in this movie if they had sat down, conserved their energy someone would have come to save them.
