Buteyko Breathing: Understanding Nasal Breathing and the Control Pause

When we decide to work on our breathing, the first instinct is often to take a bigger breath. Buteyko takes a different starting point: noticing your everyday breathing and exploring a quieter, less effortful pattern. It is not about filling your lungs as much as possible or proving how long you can go without air.

The method can sound complicated when it is reduced to numbers, carbon dioxide theories or impressive breath-hold times. I find a more useful starting question is simpler: can you pay attention to your breathing without turning it into another performance task? Here is an introduction to the approach, the control pause and the limits worth understanding before you begin.

What Buteyko breathing actually involves

Buteyko is a breathing-retraining approach associated with physician Konstantin Buteyko. Common elements include breathing through the nose, relaxing unnecessary effort and working with reduced breathing and short pauses. It is different from practices built around rapid, forceful breathing or maximum breath holds.

“Less” does not mean depriving yourself of air. It is not a general instruction to suppress your breathing while exercising, feeling ill or struggling for breath. A breathing pattern needs to suit what your body is doing. If changing it feels difficult, a respiratory physiotherapist can help assess what is happening rather than leaving you to guess.

This is also why I would separate curiosity about a method from promises about its effects. Learning to notice a habit can be worthwhile without assuming that one breathing technique is the answer to every symptom.

Why the nose matters

Your nose helps prepare incoming air by warming it, adding moisture and filtering particles. For a fuller explanation of these functions, see Cleveland Clinic’s guide to nose and mouth breathing.

Nasal breathing and belly breathing are not competing techniques. One describes the route the air takes; the other describes movement involving the diaphragm. You can explore both without forcing your abdomen out or taking oversized breaths. My guide to nasal, belly and mouth breathing explains that distinction in more detail.

If your nose is blocked, forcing it is not the solution. Occasional mouth breathing is normal. Persistent difficulty breathing through the nose deserves attention to its cause, not pressure to keep your mouth closed.

The control pause is an observation, not a health score

In Buteyko practice, the control pause is a brief, comfortable pause after an ordinary exhalation, ending at the first clear urge to breathe. It is deliberately different from holding on until you cannot tolerate it. Practitioner Neil Tranter describes this distinction in his explanation of the control pause.

Treat the number as a personal observation, not a diagnosis, a measurement of oxygen in your blood or a reliable summary of your health. How you perform the pause affects the result. Comparing a relaxed pause with a strained breath hold is not comparing like with like.

There is no target time you need to achieve here. If you finish gasping or feeling tense, the pursuit of a number has overtaken the point of the practice. You can also skip measurement entirely and simply notice a few comfortable breaths.

What the research can—and cannot—say

The 2020 Cochrane review by Santino and colleagues examined breathing exercises for adults with asthma. It found possible benefits for quality of life, but included several methods, not just Buteyko. Its findings do not establish that this particular app treats asthma or that the method benefits everyone.

Breathing practice is not a reason to stop inhalers or change prescribed treatment. The British Thoracic Society’s physiotherapy guidance also distinguishes complementary breathing strategies from replacement treatment. Discuss persistent breathing symptoms with a healthcare professional.

A gentle starting point for everyday awareness

You do not need to begin with breath holding. Sit somewhere comfortable and let your breathing settle. Notice whether your shoulders are tense, whether you are trying to take unusually large breaths and whether nasal breathing feels easy. Leave space for an ordinary, unforced breath rather than imposing a demanding rhythm.

If you would like a structured introduction to breathing retraining, Cambridge University Hospitals’ patient information is a useful place to start. Individual difficulties may need individual guidance.

Stop if you feel dizzy, breathless or unwell. If you have a medical condition, are pregnant or are unsure whether breathing pauses are appropriate, ask a clinician first. Never practise breath holds in water, while driving or anywhere a loss of attention could put you at risk. New or severe breathing difficulty needs medical attention, not an app exercise.

I built Buteyko Atmung for measuring the control pause and bringing attention to quieter breathing. If you are curious, explore the app—but keep the focus on awareness, not records. A number can accompany a practice; it should never become more important than how you feel.
