Asthma, Snoring, Hay Fever, Stress, Anxiety, COPD, sleep apnoea, are associated with  disordered breathing, meaning we breathe more than is necessary for the task at hand. When we over-breathe we upset the moment-to-moment regulation of the pH in our blood, making it more acidic, which reduces the amount of O2 available (Bohr Effect) to our  organs and muscles, effecting the nervous, cardiovascular, respiratory and immune system.
We experience this as headache, shortness of breath , palpitations, fatigue, irritability,
tight neck and shoulders etc. These unpleasant feelings cause us distress, which then makes our breathing more chaotic and our symptoms more severe and multiple.

Buteyko Breathing Retraining leads to controlled and task appropriate Carbon Emission (CO2 ) thanks to neuro plasticity. Using well researched situation appropriate breathing habits helps both the kidneys and the lungs to keep your pH and thus your metabolism at optimal function. You will recognize this state by its good feeling and absence of symptoms.
