During the session, a sauna master pours water mixed with essential oils on hot stones to create scented steam, while participants take deep breaths. Aufguss sessions can also help your body deal with temperature fluctuations and improve your resilience to such changes. Pouring sessions with an Aufguss master have many benefits:
They stimulate blood flow and strengthen the immune system: High temperatures expand blood vessels, resulting in a higher blood flow throughout the body. A better flow of blood can reduce inflammation and help heal injuries.
They relieve joint and muscle pain: A hot sauna session can help relax muscles, relieve tension and ease joint and muscle pain.
They help eliminate body toxins: Sweat helps eliminate body toxins, which can benefit skin health, relieve oxidative stress, and strengthen the immune system.
They ease your stress and help you relax: Sauna helps fight stress and anxiety by helping you relax and release endorphins, i.e. the well-being hormones.
They help you sleep better: Your body temperature goes up during the session, then drops suddenly when you get out of the sauna. This helps regulate your circadian rhythm and sleep better.
They give you an overall sensation of well-being: Thanks to the atmosphere and the peaceful warmth created by the sauna, your body enters a state of intense relaxation.
