Coherent Breathing
Your heart doesn’t tick along like a clock. Even when you’re resting, the gap between one beat and the next keeps shifting, a little quicker as you breathe in and a little slower as you breathe out.
That flexibility is a good sign. And you can influence it, simply by changing the pace of your breath.
What is it?
01Coherent breathing, also called resonance breathing, means breathing slowly and evenly at around five to six breaths per minute. That’s roughly five seconds in and five seconds out, with no holds.
It’s the same pace used in heart rate variability (HRV) biofeedback, where a device or app shows you, in real time, how your heart rhythm responds to your breath.
What may it help with?
02People often use coherent breathing to ease stress and anxiety, and to help them feel more emotionally steady.
It’s less of a rescue breath and more like training. Practised regularly, the aim is a calmer baseline, so that life’s bumps knock you around a little less and you come back to centre a little sooner.
How does it work?
03Heart rate variability is the natural variation in time between your heartbeats. Higher HRV is generally linked with a more flexible, resilient nervous system, one that can rise to a challenge and then settle again.
At around six breaths a minute, something interesting happens. Your breathing and heart rhythm tend to move in sync, and the swings in heart rate become larger and smoother. This is the “resonance” in resonance breathing, and it increases HRV.
With regular practice, this may help your body recover from stress more easily.
What does the evidence say?
04Most of the research looks at HRV biofeedback, which uses this same breathing pace, often with a device showing your heart rhythm on a screen. The findings are encouraging.
A 2017 review of 24 studies found that HRV biofeedback was linked to a large reduction in stress and anxiety [1]. A 2020 review of 58 randomised trials found benefits across a wide range of outcomes, with the largest for anxiety, depression and anger [2].
You don’t need a clinic to practise, either. A 2025 review of 18 studies of HRV biofeedback done at home or remotely found it eased symptoms of depression and improved heart rate variability. Shorter daily practice, under 20 minutes, seemed to work well [3].
How to practise
05Sit back in a comfortable chair with your feet on the floor. Let your shoulders drop. Breathe in gently through your nose for about five seconds, letting your belly expand. Then breathe out gently for about five seconds. No pause at the top or the bottom, just a smooth, continuous wave, in and out. Keep the breath soft rather than forced. If five seconds feels like a stretch, start with four and build up over time. Stay with it for five to twenty minutes, once or twice a day.
Tools that can help
- A breathing app or paced audio track that guides your timing
- A simple timer, or a visual that slowly grows and shrinks
- HRV biofeedback with a psychologist or allied health professional, if you’d like to see your heart rhythm respond
Considerations
06Go gently. There’s nothing to win by forcing longer breaths. If you feel dizzy or light-headed, return to your normal breathing.
Start simple. Devices can be motivating, but a timer and your own breath are enough to begin.
