A guide to the drug-free approach of the Buteyko Method for asthma, and general health and well-being. At the heart of the Buteyko Method lies the recognition that some 200 diseases, including respiratory conditions, develop because of hyperventilation. By altering your breathing patterns, you can radically improve your health, relieve symptoms and sometimes even eradicate illnesses without the need for drugs. The simple breathing exercises in this five-day programme are based on 45 years of practical and empirical research by leading Russian medical scientist, Professor Buteyko, and are used around the world.
