Question 1

What is hypocapnia?

Accepted Answer

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.

Question 2

Is Buteyko breathing recognized by medical guidelines?

Accepted Answer

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.

Question 3

How is Buteyko different from myofunctional therapy?

Accepted Answer

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.

Question 4

Can breathing exercises replace CPAP?

Accepted Answer

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