Hammam's temperatures are around 40-50 degrees Celsius and humidity is close to 100%.
These are very different conditions, with very different body response.
Which makes it absolutely unbearable. By the way, that combination of temperature + humidity will cause severe hyperthermia (which can be deadly) faster than people think.

The last time it was held, a Russian died and a Finn ended up in hospital with severe burns.
The problem is that staying as long as possible in a sauna can be fatal.
A different Finn won.
