Buteyko Breathing Research & Science

Research and Clinical Trials

The link between dysfunctional breathing and asthma which was identified by Professor Buteyko in the 1950’s, is now appearing with increasing regularity in the western medical literature.

Behavioural programmes centred on breathing exercises and hyperventilation reduction techniques (including physiotherapist-delivered breathing programmes such as the Papworth method, and the Buteyko method) can improve asthma symptoms, quality of life and reduce bronchodilator requirement in adults with asthma, although have little effect on lung function

Obstructive Sleep Apnoea Publications


A 2010 survey of Buteyko Institute practitioners who had taught the method to over 11,000 people with sleep apnoea found that:

  • Over 95 percent of clients with sleep apnoea had improved sleep.
  • Approximately 80 percent of clients had been able to cease use of their CPAP machine or oral appliances.
  • Symptoms such as snoring, headaches, restless legs, low concentration levels and decreased energy levels also improved in the majority of clients.

Dysfunctional Breathing / Role of Buteyko

The British Medical Journal of 5 May 2001 stated that “If dysfunctional breathing is as common as our data show, facilities for breathing retraining need to be available as part of the overall management of asthmatic patients” .

Articles appearing in Australian Doctor and the Medical Observer magazines in May 2001 now seem to substantiate the fact that dysfunctional breathing is a recognised significant factor in asthma and that breathing retraining should be an integral part of asthma management. The Buteyko Institute Method is designed to correct dysfunctional breathing patterns.

Summary of Scientific Principles

The Buteyko Institute Method is scientifically based on the standard medical principles of respiration, the normalisation of breathing and the Bohr Effect.

  • Ideal respiration is 4-6 litres of air per minute, equivalent to approximately 10 breaths per minute.
  • People with respiratory disorders have been found to breathe from 2 to several times this amount, resulting well in excess of 20,000 breaths per 24 hour day.
  • Under normal circumstances, the lungs expect measured volumes of air via the nasal passage, where it has been filtered, disinfected, warmed and moisturised.
  • Large volumes of untreated air, via the mouth, cause drying of airways, irritation and greater exposure to allergens viruses and bacteria.
  • Hyperventilation, over breathing and mouth breathing all contribute to the ‘dumping’ of CO2 from the body, upsetting the O2 – CO2 balance.
  • CO2 is a natural bronchodilator and correct blood and alveolar levels prevent the smooth muscle in the bronchioles, and in other parts of the body from going into spasm.
  • Sustained low levels of CO2 cause the breathing centre in the medulla of the brain to reset to a level which encourages hyperventilation or over-breathing. The average person with asthma breathes around 14 litres per minute, and has a CO2 level of 30 to 36mm Hg (40mm Hg is considered the normal healthy amount).
  • Buteyko exercises train people to breathe through their noses, reduce their breathing to normal levels, keep their mouths closed and retain a higher proportion of the CO2 produced by the body.
  • With practice, the Buteyko method allows the person to permanently elevate their levels of CO2 causing the breathing reflex to return to normal. The CO2 level rises to the normal level of 40mm Hg pa.

Symptoms of Dysfunctional Breathing or Hyperventilation

Many symptoms and conditions are reported in the medical literature as being either caused or exacerbated by hyperventilation. The Buteyko Institute Method therefore has significant potential to revolutionise health management in the future.

Respiratory: asthma ,cough, production of mucus, blocked or runny sinuses, chronic throat tickle, shortness of breath, tightness in or about chest, sighing respiration, excessive yawning.

Neurovascular: disturbances of consciousness, faintness, dizziness, unsteadiness, impairment of concentration and memory, feelings of unreality, “losing mind”, paresthesia, numbness, tingling and coldness of fingers, face and feet

Musculoskeletal: tremors and coarse twitching movements, diffuse or localised myalgia and arthralgia, carpopedal spasm and generalised tetany (infrequent).

Cardiovascular: palpitations, skipped beats, tachycardia, atypical chest pains, sharp precordial twinges, dull precordial or lower costal ache, variable features of vasomotor instability

Gastrointestinal: oral dryness, globus, dysphagia, left upper quadrant or epigastric distress, aerophagy, belching, bloating, flatulence.

Psychic: variable anxiety, tension and apprehension, inappropriate pseudocalmness (hysterical subjects)

General: sleep apnoea, snoring, easy fatigability, generalised weakness, irritability and chronic exhaustion, frightening dreams

Dental: narrowed upper jaw, overcrowding, tooth decay and gum disorders.
