How much can breathing lower my blood pressure?

Slow breathing practice typically produces a few millimetres of mercury systolic with consistent daily practice. High-resistance inspiratory muscle training has produced larger reductions — around nine millimetres in trials — but needs a device and a protocol.

Can I stop my medication?

No, not on this basis. Home readings and a discussion with your clinician are how medication changes happen. Stopping antihypertensives independently is one of the more dangerous things you can do with a wellness article.

Should I avoid breath holds?

If your blood pressure is uncontrolled, yes — breath-hold work and heavy lifting against a closed airway both produce sharp pressure spikes. Slow continuous breathing has no such effect and is the appropriate practice here.

Breathing exercises for blood pressure: a real effect, and a small one

Your reading was high again. You would rather not add another tablet, and you have read that breathing can bring it down. You want to know whether that is a real number or a wellness claim.

Do this now

Six breaths a minute, fifteen minutes

10 minutes

Sit comfortably, back supported, feet flat. Do not lie down.
Mouth closed. In through the nose for about five and a half seconds, out for about five and a half. No holds.
Keep it quiet, small and unforced. Straining defeats the point.
Ten to fifteen minutes. The effect in trials comes from doing this most days, not from doing it once.
Take your reading at the same time of day, seated, after five minutes of rest — not immediately after the session.

Run it with a timer

What slow breathing does to blood pressure

Breathing at around six breaths a minute increases baroreflex sensitivity and shifts autonomic balance, and regular device-guided slow breathing has lowered blood pressure in randomised trials and meta-analyses. The size is modest — typically a few millimetres of mercury systolic — and it requires consistent practice, usually fifteen minutes most days. A few millimetres is not nothing at a population level; it is also not a replacement for medication in someone with significant hypertension.

The better-evidenced relative: inspiratory muscle training

High-resistance inspiratory muscle strength training — breathing against resistance through a handheld device for around five minutes a day — has produced larger reductions in randomised trials, in the range of nine millimetres of mercury systolic in midlife and older adults, with effects comparable to some medication and exercise interventions. It is a device and a protocol rather than a free technique, and it is the most promising breathing-based intervention in this area.

Where it sits in a treatment plan

Alongside the interventions with the largest effects: reducing sodium, losing excess weight, aerobic exercise, limiting alcohol, and medication where indicated. Breathing practice is a reasonable, safe addition that also improves sleep and stress, which matter for blood pressure by other routes. It does not earn a place ahead of any of those, and it is not a reason to skip a prescription.

What changes it, over a week

Most days, 15 minutes
Slow breathing at about six breaths a minute, seated, at a consistent time.
Measure properly
Same time daily, seated, arm supported, after five minutes of rest, two readings a minute apart. Bad measurement is the most common cause of bad decisions here.
The big levers
Sodium, alcohol, weight and aerobic exercise. None of them is as interesting as breathing and all of them do more.
Medication
Take it as prescribed. Bring your home readings to your next appointment and let the clinician decide what changes.

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:

A reading over 180/120, or over 160/100 with symptoms — contact a clinician promptly
Severe headache, chest pain, breathlessness, visual change, or weakness with a high reading — emergency
Pregnancy with raised blood pressure, or any swelling and headache in pregnancy — urgent assessment
Never stop or reduce blood-pressure medication because breathing practice is helping — that is a clinician's decision
Avoid breath-hold training, and heavy lifting with a full breath hold, if your blood pressure is uncontrolled
