This intense Aufguss session is very special. The location itself is unique, a stone sauna with high humidity. Suspended above the fire is a bucket, which you can operate with a button. Pouring extra water on the stones increases the humidity and as a result, you will experience a more intense heat sensation.
During the Mushara session, it is the Aufguss master who decides when to pour water infused with essential oil on the stones. He then wafts bursts of hot air over you by flapping a towel or waving a fan, which gives you a real adrenaline kick. And, at the end of the session, he gives you a nourishing cream with ylang-ylang.
