What is the difference between sanarium and sauna?

A Sanarium uses a lower heat than a Sauna, usually between 30 and 40 degrees and also uses humidity, around 50 percent (almost like a hot sunny day in the med). It's like a cross between a sauna and a steam room.

As it's not as punishing as a sauna, it can be used for longer periods and is more effective for a warm down after a workout and is also better for the skin.
