Probably the world’s most famous wellness method: the sauna has its origins in Finland and involves far more than simply sitting and sweating. A sauna session is more like a ceremony. Time spent in the sauna is followed by a cool-down in the fresh air and cold affusions. A sauna aids in regenerating the body and relaxing the mind. It improves blood supply and thus stimulates the metabolism. Stress is reduced and, in the process, the skin’s overall appearance becomes more beautiful. Those who regularly take a sauna, are also making long-term improvements to their immune system. The constant temperature change from hot to cold strengthens the body’s defensive mechanisms and prevents infectious diseases.
