Buteyko Breathing: Can It Calm Nighttime Snoring?

Doctor with a stethoscope at a desk reviewing notes on breathing evidence

Breathing less to snore less sounds backwards. That’s why the Buteyko method deserves a careful look rather than a shrug or a sales pitch.

The short version: the theory is interesting, the asthma data is modest, and the snoring data is missing.

The Theory in Plain Terms

Buteyko proposed that chronic over-breathing, or hyperventilation, lowers carbon dioxide in the blood, a state called hypocapnia. He argued this tightens airways and disturbs body chemistry.

Practitioners say the fix is breathing through the nose, taking smaller breaths, and relaxing, then tracking progress with a comfortable breath-hold known as the control pause.

Where the Evidence Is Strongest: Asthma

Soviet researchers ran a first official asthma study in Leningrad in 1968 and a second in Moscow in 1980, after which the Ministry of Health endorsed the method for bronchial asthma (details on the Buteyko method page).

Modern reviews are more cautious. The 2020 Cochrane work on breathing exercises for adult asthma pointed to possible benefits for quality of life, symptoms tied to over-breathing, and lung function.

It didn’t isolate Buteyko, and its certainty ratings ranged from moderate to very low.

A 2014 British guideline allowed that Buteyko may ease some symptoms, but said peak lung function barely moves.

Where the Evidence Thins Out

Sleep apnea has only a small body of research. For snoring, we found no trial that measured it.

A 2005 review concluded there was no convincing evidence that changing carbon dioxide levels in people with asthma is desirable or achievable. Australia’s Department of Health reached a similar place in 2015, when it assessed 17 alternative therapies and found no clear evidence for Buteyko.

What Does Have Data: Throat and Tongue Training

A 2015 meta-analysis in Sleep pooled nine adult studies of myofunctional therapy, covering 120 people. The mean apnea-hypopnea index dropped from 24.5 to 12.3 events an hour, and polysomnographic snoring fell from 14.05 to 3.87 percent of total sleep time.

Daytime sleepiness scores also improved, from 14.8 to 8.2 on the Epworth scale. The two pediatric studies covered just 25 children, so that part is promising but small.

How to Judge a Claim Like This One

  • What exactly was measured: symptoms, lung function, or snoring?
  • Who was studied, and how many people?
  • Was there a comparison group, and for how long were people followed?
  • Does the claim list a handful of conditions, or promise over a hundred?

Run Buteyko through that list and the asthma data gives you something, the apnea data gives you a little, and the snoring data gives you nothing yet. The method spread from the Soviet Union to Australia, New Zealand, Britain, and the United States, and popularity isn’t evidence either way.

How Snoring Works, According to the Clinic

Mayo Clinic describes snoring as tied to airway anatomy, alcohol, nasal problems, sleep loss, and back sleeping.

It also notes that snoring is often associated with obstructive sleep apnea, though not every snorer has it.

A Practical Reading of the Research

If you try Buteyko, think of it as a nasal-breathing and relaxation routine, and judge it by your own recordings. Our natural snoring remedies and 7 zero-cost remedies make low-risk companions.

If the snoring comes with gasping or heavy daytime sleepiness, our look at CPAP alternatives explains what to ask a sleep physician.

Weighing the Claims Before You Commit

A good rule for any breathing claim is to ask what was measured, in whom, and for how long. For snoring, the answer so far is nothing.

Frequently Asked Questions

It means abnormally low carbon dioxide in the blood. Buteyko’s theory says chronic over-breathing causes it, though a 2005 review found no convincing evidence that changing CO2 in people with asthma is desirable or achievable.

Partly. A 2014 British asthma guideline said it may help some symptoms and quality of life, while Australia’s 2015 review found no clear evidence of effectiveness.

Buteyko targets breathing volume and nasal breathing, while myofunctional therapy trains the muscles of the tongue and throat. Only the latter has pooled snoring data so far.

Nothing we found supports that. The myofunctional review calls the exercises an adjunct to other treatments.
