The Buteyko Method was developed in the 1950s by Dr. Konstantin Buteyko, a Russian doctor. The main premise is that we have developed unhealthy breathing habits over the years that affect CO2 levels in the blood thus causing changes in blood chemistry and our metabolism which, over time, cause symptoms and diseases. Through a programme of breathing exercises and lifestyle changes, CO2 tolerance is increased and healthy functional breathing is restored. Restoring healthy functional breathing and tolerance to healthy blood CO2 levels helps create a healing environment that may address symptoms and restore health.
