Resonance breathing means breathing at the slow pace, typically between 4.5 and 7 breaths a minute, where your heart rate swings up and down the most with each breath. Most people land near 5.5 to 6. Studies often use a heart monitor as feedback and report lower stress and anxiety, but many are small and the research is early. You need a heart-rate sensor for your exact rate, so the steps below are a practical guide, not a measurement.
Slow, smooth breathing without holds is gentle, but any breathing exercise can make some people lightheaded. Stop and breathe normally if that happens. If you have a heart or lung condition or are pregnant, ask your doctor first. More in who should not do breathwork.
If you have read about slow breathing, you have seen the number 6. Six breaths a minute is the round figure behind many apps and watches. But you may also have read "find your own resonance frequency", which suggests the best pace is personal. Is it?
The idea comes from a method called heart rate variability biofeedback (HRVB). Heart rate variability, or HRV, is the small natural variation in time between heartbeats. In HRVB, a sensor shows your heartbeat live while you breathe slowly, and you adjust your pace until the swings in your heart rate are as big and smooth as possible. Here is the plain-words version, plus a way to explore your own pace at home.
How do you find your resonance breathing rate at home?
A proper test needs a heart-rate sensor and software, usually with a trained practitioner. The method in the study below was to try five rates in turn and compare. You can do a rough, comfort-based version at home. It is a guide only, and I did not find a study that tests it.
- Pick a quiet moment. Sit upright with your back supported. Use a free pacer app or pacer audio that can set breaths per minute.
- Breathe through your nose with a smooth, even breath, in and out for the same time. At 6 a minute that is 5 seconds in, 5 seconds out.
- Try five rates for two minutes each, with a minute of normal breathing between: 7, 6.5, 6, 5.5 and 5 breaths a minute. Taller people and men may feel more at home at the slower end.
- After each one, write down how easy it felt (1 to 5), whether you felt air-hungry or smooth, and how relaxed you were.
- Choose the rate that felt smoothest and most comfortable. If two tie, pick the faster one.
- Practice your rate for 5 minutes a day for a week, and note how you feel. Your numbers may drift from day to day, which is fine.
If you wear a heart-rate sensor, you can look for the rate where the heart rate curve makes the biggest, smoothest waves. A consumer HRV number does not replace a formal assessment. No study I read says how many minutes a day are needed.
What is resonance breathing?
Your heart speeds up when you breathe in and slows down when you breathe out. At a certain slow rate, these swings add up and become as big as they can be for you. Researchers call that your resonance frequency (Lehrer and Gevirtz, 2014). Think of pushing a swing: push at just the right rhythm and each swing gets bigger.
According to that review:
- The most often cited rate is about 6 breaths a minute.
- A refined average is about 5.5 breaths a minute, around 11 seconds per breath.
- Taller people and men tend to have lower resonance rates. Age and weight did not matter.
Another study puts the range at 4.5 to 7.0 breaths a minute, with 5.5 the most common (Steffen et al., 2017).
Does your own breathing rate really matter?
Steffen and colleagues tested this in 95 undergraduates, average age 20. They found each person's resonance rate first. Then they randomly assigned people to 15 minutes of breathing at their own rate, breathing one breath a minute faster than their rate, or sitting quietly. Everyone then did a stressful mental task.
- The own-rate group had a higher HRV ratio (LF/HF) than the quiet group. The one-breath-faster group did not.
- Positive mood rose only in the own-rate group.
- Blood pressure was lower during the breathing in both breathing groups. During the stressful task, only the own-rate group had lower systolic pressure (the top number) than both other groups.
- Two other HRV measures did not differ between groups.
So there was a small edge for the personal rate. But notice how close it was: one breath a minute faster did nearly as well on several measures. This was one session in students, and effects over weeks are unknown.
A separate study of 47 healthy college students compared four patterns around 6 breaths a minute. Breathing at 5.5 a minute with equal in and out time gave the highest HRV measures, and all four patterns raised relaxation. I could read only the abstract (Lin et al., 2014).
Does resonance breathing help with stress and anxiety?
For HRV biofeedback, a 2017 meta-analysis (a study that pools many studies) combined 24 studies with 484 participants. It found a large drop in self-reported stress and anxiety compared with control groups (Goessl et al., 2017). The authors still call for more well-controlled studies. I could read the abstract only.
A 2021 meta-analysis of 14 randomized trials with 794 adults found a medium drop in depression symptoms with HRVB, with moderate differences between studies (Pizzoli et al., 2021). Again, abstract only.
Why be cautious?
The review that introduced the idea is candid. Its authors say most of the proposed explanations are still hypotheses with little testing, and that other explanations, such as distraction or feeling capable, have not been ruled out. They also note that few of the many conditions HRVB has been tried for have extensive support from controlled studies (Lehrer and Gevirtz, 2014). I read the first part of that paper, not all of it.
Also, a review of 15 studies noted that breathing at about 6 a minute can push up a common HRV reading by itself (Zaccaro et al., 2018), so a higher number on your watch does not prove you are calmer.
The research in a nutshell
| Study | Who | What they found |
|---|---|---|
| Steffen et al. 2017 | 95 undergraduates, one session | Own rate: higher LF/HF, better positive mood, lower systolic pressure under stress. |
| Lin et al. 2014 (abstract only) | 47 college students | 5.5 breaths a minute, equal in and out, gave the highest HRV. |
| Goessl et al. 2017 (abstract only) | 24 studies, 484 people | Large drop in self-reported stress and anxiety with HRV biofeedback. |
| Pizzoli et al. 2021 (abstract only) | 14 trials, 794 adults | Medium drop in depression symptoms with HRV biofeedback. |
How strong is the evidence? Early to mixed. Biofeedback programs look promising in pooled studies, but the extra benefit of finding your own exact rate, compared with simply breathing slowly near 6, is not well tested.
Who should skip this or check first
- Studies of this method mostly enrolled healthy young people. The 2017 resonance study left out people with a history of heart disease or with medicines that affect heart rate or blood pressure (Steffen et al.). If you have a heart condition, ask your doctor first.
- Fast or forceful deep breathing can cause lightheadedness because it lowers carbon dioxide in the blood (Cleveland Clinic). Keep the breath soft and easy.
- If you are pregnant or have a lung condition, ask your doctor before trying a new breathing routine.
- If stress or anxiety is constant or is getting in the way of life, please speak to a doctor or mental health professional. Breathing exercises are a small tool, not a replacement for care.
Questions people ask
What is the resonance frequency breathing rate?
For most people it falls between 4.5 and 7 breaths a minute, and 5.5 is the most common rate reported in HRV biofeedback studies. Your personal rate may differ.
Is resonance breathing the same as 6 breaths a minute?
They overlap. Six breaths a minute is close to the average resonance rate, so slow breathing at 6 is often used as a simple stand-in. Resonance breathing is the version where the rate is fine-tuned to you.
Do I need a device to find my rate?
For an exact answer, yes: a sensor that shows your heartbeat live. The home steps above are a rough guide based on comfort.
Is it better than just breathing at 6 a minute?
Not clearly. In the single-session study above, the personal rate had a small edge on some measures. Long-term comparisons were not part of what I could verify.
Does a higher HRV mean I am more relaxed?
Not necessarily. Breathing at 6 a minute can raise some HRV readings by itself, and HRV is only one rough indicator of how the body is doing.
