The Gasteiner Heilstollen therapy is a combination of mild hyperthermia and radon therapy at alpine altitude. It is based on entries into the 2.5 km long mountain tunnel with a stay of approx. 50 minutes in one of five therapy stations with increasing heat (37°C to 41.5°C) and varying humidity (70 to 100%). The different humidity and temperature in each station allows the doctors to provide treatment adapted to the patient.

In the case of chronic diseases of the musculoskeletal system, such as ankylosing spondylitis, rheumatoid arthritis or fibromyalgia, this results in remarkable effects of pain relief. These last noticeably for months. Medication savings of up to one year have been scientifically proven. This effective natural remedy also has an impressive effect on diseases of the respiratory tract or the skin. A visit to the Gasteiner Heilstollen is also worthwhile for general prophylaxis and immuno-stabilization.
