Away from traffic and everyday life, the pollutant-free high-altitude air offers properties that are described in high-altitude medicine as particularly beneficial to the health of the body. The changed oxygen content at altitude challenges the body and brings the interaction of lungs and cardiovascular system to full speed. Due to the clean mountain air, the lungs are better supplied with blood and the body absorbs oxygen more effectively. This stimulates the organism to produce more red blood cells and improves blood flow, which provides the cells with a better supply of fresh oxygen. Accelerated cell renewal takes place.
