Coherent breathing: 6 breaths a minute and what it does
Coherent breathing means about 6 slow breaths a minute: in for 5 seconds, out for 5, with no holds. Try 5 minutes, up to 3 times a day.
- What it is: coherent breathing means breathing at about 6 breaths a minute, usually in for 5 seconds and out for 5, with no holds.
- Why 6 a minute: at around this rate your heart rate rises and falls most strongly with each breath, which is why it is also called resonance breathing.
- How long: a common plan is 5 minutes, 3 times a day, known in France as the 365 method; 5 to 10 minutes once a day is a fine start.
- Evidence: a 2018 review of 15 studies linked slow breathing to higher heart rate variability and less anxiety, but a 2023 trial of 400 people found no extra benefit over breathing at 12 a minute.
- Safety: it is gentle and has no breath holds; if you feel light-headed, breathe a little less deeply and return to normal breathing.
Shimmr Binaural beats for meditation, sleep and focus Get Shimmr Coherent breathing is slow, even breathing at about 6 breaths a minute: in for 5 seconds, out for 5, with no pauses. It is also called resonance breathing, and in France and Spain it is known as cardiac coherence. At this pace your heartbeat and your breath fall into step. Here is how to do coherent breathing, why 6 a minute matters and what the studies really show.
How do you do coherent breathing?
Breathe in gently for 5 seconds and out for 5 seconds, without holding your breath, for about 5 minutes. Here is how to start:
- Sit upright with your feet flat, or lie down. Rest your hands on your belly.
- Breathe in softly through your nose for 5 seconds. Let your belly rise first.
- Breathe out through your nose or loose lips for 5 seconds. Do not push the air out.
- Go straight into the next breath, with no pause.
- Keep going for 5 minutes. That is about 30 breaths.
Breathe slowly, not deeply. Big breaths at this pace can make you light-headed. If 5 seconds feels long, start with 4 in and 4 out, which is 7 or 8 breaths a minute, and slow down over a few days. A clock with a second hand or a simple count in your head is enough.
Why 6 breaths a minute?
At about 6 breaths a minute, your heart rate swings most strongly with your breath. Your heart naturally speeds up a little as you breathe in and slows down as you breathe out. A 2014 review explains that most studies find the biggest swings at around 0.1 Hz, which is one breath every 10 seconds, or 6 a minute. The exact rate varies a little from person to person.
The reason is the baroreflex, the system that senses blood pressure and adjusts your heart rate to keep it steady. At this pace the breath and the baroreflex work in rhythm and boost each other, a bit like pushing a swing at just the right moment. Bigger swings show up as higher heart rate variability (HRV), how much the gap between heartbeats changes, which is generally a sign of a body that can shift easily between effort and rest.
What is the 365 method?
The 365 method is a simple plan for coherent breathing: 3 times a day, 6 breaths a minute, for 5 minutes. It was made popular in France by the doctor David O’Hare and is now one of the best known breathing routines in French-speaking countries.
| Number | Means |
|---|---|
| 3 | Sessions a day, for example morning, before lunch and late afternoon |
| 6 | Breaths a minute, 5 seconds in and 5 out |
| 5 | Minutes per session |
You do not need to follow it exactly. If three sessions feel like a lot, one 5 to 10 minute session a day is a good place to start.
Does coherent breathing really work?
Slow breathing clearly changes how your body behaves, but whether coherent breathing does more than any quiet breathing break is less clear.
On the positive side, a 2018 systematic review pulled together 15 studies of slow breathing, under 10 breaths a minute, in healthy people. Slow breathing raised heart rate variability and was linked to feeling more relaxed, more comfortable and more alert, with less anxiety, anger and low mood.
The honest counterweight is a 2023 randomised trial with 400 people, one of the largest breathing studies so far. One group practised coherent breathing at about 5.5 breaths a minute, the other a placebo pattern at 12 breaths a minute, for about 10 minutes a day over 4 weeks. Stress, anxiety and mood improved in both groups, by the same amount. So the daily habit of stopping to breathe may matter as much as the exact pace.
Is coherent breathing the same as box breathing?
No. Coherent breathing has no holds: just a smooth 5 seconds in and 5 seconds out. Box breathing adds a 4 second hold after both the in breath and the out breath, and 4-7-8 breathing adds a long hold and an out breath twice as long as the in breath. If holding your breath feels uncomfortable, coherent breathing is often the easiest of the three.
How can you make coherent breathing a habit?
Tie it to things you already do, such as your morning coffee, the walk back from lunch or the end of the workday. A steady sound in the background helps you stay with it for the full 5 minutes. In Shimmr, Journeys guide you through weight, breath and sound, and the Tense → At Ease Shift glides from Beta to Theta over 15 minutes while you keep your own slow count. Shimmr does not pace your breathing or measure HRV. Your minutes can go to Apple Health as mindful minutes.
Coherent breathing is gentle, but if you have a heart or lung condition, or slow breathing brings on panic, talk to your doctor before you make it a routine. If stress is a bigger part of your life, our guide to binaural beats for anxiety covers another gentle aid. Never practise while driving.
Common questions
How do you do coherent breathing?
Sit comfortably and breathe in gently through your nose for 5 seconds, then out for 5 seconds, without holding your breath. Keep going for 5 minutes, which is about 30 breaths.
What is the 365 method?
It is a simple plan for coherent breathing, popular in France: 3 times a day, 6 breaths a minute, for 5 minutes. Many people do it in the morning, before lunch and in the late afternoon.
How long should you practise coherent breathing?
Five minutes is the usual session, once to three times a day. In a large 2023 trial, people practised about 10 minutes a day for 4 weeks.
Does coherent breathing really work?
Slow breathing reliably changes heart rhythm and many people feel more at ease. But a 2023 trial of 400 people found that breathing at 12 breaths a minute helped stress just as much, so part of the benefit may come from simply taking time to breathe.
Is coherent breathing the same as box breathing?
No. Coherent breathing is a smooth in and out of about 5 seconds each with no holds, while box breathing adds a 4 second hold after both the in breath and the out breath.
