The Eucapnic Buteyko Theory Eucapnic Breathing is a form of breathing training which normalizes levels of carbon dioxide by controlling ventilation levels. This method incorporates the theory and practice of Professor Buteyko and other research on breathing and physiology. Additionally it includes work on diet, anxiety and stress, sport and exercise, and the muscles of respiration.
Carbon dioxide is far more than a waste gas.
It is an crucial regulator of one's respiratory system, immune system, nervous system and one's energy metabolism. The key to efficient levels of CO2 is breathing. Normalising breathing by reducing the volume of breathing restores the body's CO2 levels to normal. This leads to healthier respiration, a strengthened immune system, a calmer nervous system and more efficient energy metabolism. Research shows that a loss of CO2 in the lungs leads to broncho constriction and inflammation in the airways.
