Oxygen nourishes and revitalizes all cells through blood circulation when people inhale clean air. The polluted air of large cities and sedentary lifestyles cause a reduction in blood oxygen levels. At a micro level, this leads to anaerobic metabolism just like in cancer cells. Airnergy devices concentrate the oxygen in the air (90% oxygen) and moIsturize it, giving the sensation of breathing fresh air in a forest. We recommend you do this therapy in sets of 10 or 20 sessions.
