Have you ever taken part in an Aufguss session? Aufguss is a German term, defined by Collins dictionary as ‘pouring of water onto hot coals’. This energising sauna ritual, in Finnish also known as löyly, is an absolute must-try! In our public baths, you can take part daily in several Aufguss sessions for free. Below, we explain what you can expect during an Aufguss session and what the health benefits of Aufguss are.
During an Aufguss session, the Aufguss master joins you in the sauna and pours water infused with essential oils onto the hot stones. Or he or she may place ice balls with essential oils on the stones, which makes them melt. This increases both the humidity and temperature in the sauna. The Aufguss master then walks around, wafting bursts of hot air over you with a towel or fan. Expect a real adrenaline kick, quickly followed by a sense of deep relaxation.
We offer a daily extensive programme in our public baths with a wide range of Aufguss, scrubbing and relaxation sessions, which you, as our sauna guest, can take part in for free. For more information, ask our reception staff when you check in or take a look at the day’s programme displayed on our TV screens in the public baths. Also, our Aufguss masters are happy to help you if you need assistance and will gladly answer any questions you may have!
