Can breathing exercises replace my inhaler?

No, and this is the one question on the page with a one-word answer. Preventers act on airway inflammation you cannot feel, and trials show breathing exercises improve symptoms without improving lung function. Any medication change is a decision for your clinician with objective measurement.

Does the Buteyko method work for asthma?

Trials show improvement in symptoms and reliever use, with little effect on measured lung function. That is a real benefit for how you feel and an honest limit on what it is doing. Where practitioners have advised reducing medication, that has been the dangerous part, not the breathing.

Why do I feel breathless when my asthma is controlled?

Very often because a disturbed breathing pattern sits on top of the asthma, and its symptoms are almost identical. That portion does respond to retraining, which is why separating the two is worth doing with a respiratory physiotherapist if one is available.

Breathing exercises for asthma: what the trials show, and the rule that never changes

Your asthma is controlled on paper and you still feel breathless, tight and short of air much of the time. Somebody mentioned Buteyko. You would like to know whether it is real or whether it is the sort of thing that gets people hospitalised.

Do this now

Reduced-volume nasal breathing

5 minutes

This is for between attacks, never during one. During an attack: reliever inhaler and your action plan, nothing on this page.
Sit upright, mouth closed, shoulders relaxed.
Breathe through the nose and make each breath slightly smaller than you want — a mild, tolerable sense of wanting more air.
Five minutes at that level. If air hunger becomes strong, take one normal breath and go back to small.
Stop if you wheeze, cough or feel your chest tighten, and use your reliever as your plan says.

Run it with a timer

What the evidence actually supports

A Cochrane review and subsequent trials find that breathing exercises in asthma improve symptoms, quality of life and hyperventilation scores, and can reduce reliever use — while producing little or no change in objective lung function such as FEV1. That distinction is the whole point: the inflammation and airway narrowing of asthma are not what the breathing is acting on. What improves is the large symptom burden that comes from a disturbed breathing pattern layered on top of the disease.

Why the two get confused

Dysfunctional breathing is very common in people with asthma, and its symptoms — chest tightness, air hunger, an unsatisfying breath, frequent sighing — overlap almost completely with asthma symptoms. People therefore reach for a reliever to deal with pattern symptoms, which does not help, and conclude their asthma is worse than it is. Separating the two is one of the more useful things breathing retraining does.

The rule that never changes

Breathing exercises are an adjunct to prescribed care, never a substitute. Do not reduce or stop a preventer inhaler on the strength of feeling better — preventers act on inflammation that you cannot feel, and asthma deaths occur in people who felt controlled. Any medication change is a conversation with your clinician, with objective measurement, and no breathing method should ever be presented as a reason to skip it.

What changes it, over a week

All day
Nasal breathing. It warms and humidifies the air, which matters more in asthma than in most conditions.
Twice a day, five minutes
Reduced-volume nasal breathing at mild air hunger, between attacks only.
Before exercise
Warm up gradually and nasally, and follow your clinician's advice on pre-exercise reliever use. Do not replace it with technique.
Keep your plan
Preventer as prescribed, reliever available, written action plan reviewed. Track peak flow if that is part of your plan.

When this is not a breathing pattern

See a clinician — promptly, and before assuming any of this applies to you — if any of these describe you:

Any worsening breathlessness, wheeze, or increasing reliever use — follow your action plan and contact your clinician
A reliever that is not working, or is needed more than your plan allows — urgent medical assessment
Being unable to speak in full sentences, blue lips, or exhaustion with breathlessness — call emergency services
Night-time waking with cough or wheeze, which is a marker of poor control
Never reduce or stop a preventer inhaler because breathing exercises are helping — that decision is your clinician's
