How long and how often to practice breathing

The short answer

Start with five minutes, once a day, and keep it up for at least a week before you decide whether it's doing anything for you. If five minutes sounds like a lot, start with one and add more when it feels easy.

Coming back tomorrow matters more than stretching today's session. A short practice you repeat teaches you the technique. One long, isolated session leaves very little behind.

How many minutes: what studies measured

A 2023 systematic review by Bentley and colleagues pulled together 58 clinical trials covering 72 ways of practicing breathing for stress and anxiety. Of those 72, 54 showed an effect. When the researchers compared them, the ones that worked had something in common: they avoided sessions shorter than five minutes.

The surprising part is the flip side. Going past five minutes didn't change the outcome: sessions of 10, 20 or more minutes did no better than five. The authors note that the quality of the included studies was, in their words, mediocre at best, so take this as a clue and not a law.

Two more studies point the same way. In a 2023 Stanford trial with 108 adults, each person practiced for five minutes, just once a day, for 28 days. And in a small 2021 study of 47 people with no comparison group, a single five-minute session of breathing in for 4 seconds and out for 6 was followed by lower anxiety scores on questionnaires.

How often: consistency counts for more

In Bentley's review, practicing at least six sessions over a week or more was associated with the practice working. It also helped to have a person guide at least the first session, live or through audio or video. With automated guides and a single session, seven out of eight attempts showed no effect.

The Stanford trial found something similar by a different route: the daily boost in positive mood kept growing as the days of practice added up.

There's a caveat. A 2023 meta-analysis by Fincham and colleagues, covering 12 trials and 785 people, found no clear link between total practice time and the size of the effect on stress. The authors themselves point out that many studies never recorded how much people practiced at home, so the question is still open. Nobody knows yet what the minimum dose is.

A realistic plan for your first weeks

If you can't fit it in one day, do one minute. If you miss several days, just come back: there's no need to make up sessions.

• Days 1 to 3. The One-minute pause: six breaths, in for 4 seconds and out for 6. It teaches you the motion without making it hard to begin.
• The rest of week one. 4-6 breathing for five minutes, once a day, at the same time each day.
• Week two. Stay at five minutes. If you want variety, try Coherent breathing 5-5 or Cyclic sighing, also for five minutes.
• After that. Decide based on what you noticed. You can stay at five minutes, add a second short session at another time of day, or go up to ten. No option is more correct than another.

What time of day, and how many times

The studies cited here don't compare times of day, so the best time is the one you can repeat. Many people find it works to attach the practice to something they already do: after coffee, before opening email, at bedtime.

As for times per day, medical guidance varies. The UK's National Health Service (NHS) suggests at least five minutes and making it part of your daily routine. Cleveland Clinic, for learning to breathe with the diaphragm, recommends 5 to 10 minutes, three or four times a day. Those are recommendations for learning a technique, not a required minimum.

Gentle, slow breathing can be repeated several times a day as long as you feel fine. Intense breathing is different: the fast patterns and the long holds already come with a set number of rounds, and the sensible thing is to stop there.

Signs you're overdoing it

More isn't always better. If you feel dizzy, tingly or short of breath, stop and breathe at your normal pace. That usually means you're breathing too big or too fast, not that you need more practice.

If the practice turns into a chore that makes you tense, shorten it. And if you have a heart, lung or blood pressure condition, are pregnant, or have a history of panic attacks or fainting, check with your care provider first.
