[1] Buteyko asserts that numerous medical conditions, including asthma, are caused or exacerbated by chronically increased respiratory rate or hyperventilation.
The second, held at the First Moscow Institute of Pediatric Diseases in April 1980, eventually led to the head of the ministry of health to issue an order (No 591) for the implementation of the Buteyko method in the treatment of bronchial asthma.
[6] In 2019, the popular Indonesian singer Andien posted images of herself, her husband and their two-year-old son with tape over their mouths on social media.
"[8] Some studies that looked to corroborate the theory sought evidence such as by measuring the carbon dioxide levels in practitioners of Buteyko but failed to find conclusive support, leading some to propose alternate theoretical pathways for this method to improve symptoms.
The Buteyko method emphasizes the importance of nasal breathing, which protects the airways by humidifying, warming, and cleaning the air entering the lungs.
[10] Many of the studies that have evaluated breathing retraining have significant methodological flaws, including small sample sizes,[11] possible patient selection bias as well as heterogeneity in design that makes coming to a firm conclusion difficult.
[1] A 2020 Cochrane review has found that breathing exercises may have some positive impact on quality of life, hyperventilation symptoms and lung function (moderate to very low certainty).
[10] A 2014 British clinical guideline said that for adults the Buteyko method could improve some asthma symptoms and quality of life, but that it had little impact on lung function.
