The observations of a Russian doctor, Konstantin Buteyko, suggest that breathing patterns are fundamental to the natural and effective treatment of asthma. Buteyko believes that only shallow breathing, which increases the proportion of carbon dioxide in our systems, enables the body to function efficiently. The first clinical trial of Buteyko's controversial treatment, conducted in Australia, showed that 90 per cent of asthma sufferers were able significantly to reduce their dependence on medication. Alexander Stalmatski worked with Buteyko in Russia, and then practised the Buteyko Technique in Australia and England. In this book he explains the physiology behind the theory, describes how the Buteyko method works, and provides simple self-help exercises for asthma sufferers who wish to treat themselves.
