Normal breathing rate, and why slower calms

What is a normal breathing rate?

For an adult sitting quietly, 12 to 20 breaths per minute is the usual range. References vary a little at the edges: MedlinePlus, the US National Library of Medicine’s guide, gives 12 to 18 breaths a minute, and a review of slow-breathing research gives 10 to 20 (Russo et al. 2017). Your rate rises with effort, heat, a fever, pain or nerves, and settles again with rest.

Doctors call this your respiratory rate. It’s one of the four vital signs, with heart rate, blood pressure and temperature.

What is a normal breathing rate for children?

Faster, and it falls quickly in the first two years. In a review of 69 studies of healthy children, the typical rate dropped from 44 breaths a minute at birth to 26 at age 2, then kept easing down towards adult levels through childhood (Fleming et al. 2011).

Age	Typical breaths per minute
Newborn	About 44
2 years	About 26
Late teens and adults	About 12 to 20

The same review found that many published charts for children disagreed with the real data, which is why different websites give slightly different bands.

What is a normal breathing rate while sleeping?

About the same range as when you’re awake, and steadier. Studies disagree on whether it gets a little faster or a little slower. In one, 38 sleeping adults breathed more slowly in every sleep stage than when awake, and most regularly in deep sleep (Gutierrez et al. 2016). In an older study of 19 adults, sleep breathing was slightly quicker and shallower (Douglas et al. 1982).

If your watch shows your overnight rate, compare it with your own usual. A change from your normal says more than any single number.

How do you measure your breathing rate?

Count one in-breath and one out-breath as one breath. Do it at rest, and try not to change your breathing while you count, which is harder than it sounds.

Why is 6 breaths a minute special?

Because it’s close to the pace at which your heart rhythm and breathing fall into step. Your heart speeds up slightly as you breathe in and slows as you breathe out. At about 6 breaths a minute, those swings grow largest, together with the reflex that steadies your blood pressure (Lehrer & Gevirtz 2014). The exact best pace varies a little between people, roughly 4.5 to 6.5 a minute (Meehan & Shaffer 2024).

People have found this pace for centuries. In one study, reciting the rosary or a yoga mantra slowed breathing to almost exactly 6 breaths a minute, down from about 14 (Bernardi et al. 2001). Try it here: 5 seconds in, 5 seconds out.

Breathing at this pace raises heart rate variability, a marker of your body at rest, during practice and after it (Laborde et al. 2022). There’s more on what that does, and doesn’t do, in the benefits of slow breathing, and the full guide to this pace is coherent breathing.

How do you slow your breathing down?

Lengthen each breath a little at a time, rather than jumping straight to 6. Breathe low and quietly, through your nose if you can, and make the out-breath at least as long as the in-breath. Slower, not bigger: big breaths can leave you light-headed. The in-between rows, like 3 in and 4 out, can be your own patterns in Breathform with Breathform Full, so you’re not counting while you work down the table.

When 5-5 feels easy, try the slowest even rhythm: 6 seconds in, 6 out, 5 breaths a minute.

A few minutes a day for a week or so often makes 6 a minute feel natural. In one trial, 5 minutes a day of cyclic sighing for 28 days lowered people’s resting breathing rate more than mindfulness meditation did (Balban et al. 2023). For a full routine at 5 breaths a minute, see the slow breathing exercise, and for everyday habits, how to breathe properly.

What does a fast breathing rate mean?

Usually that your body needs more air for a while: you’ve moved, you’re hot, you’re in pain, you have a temperature, or you’re anxious. Anxiety often speeds breathing up and makes it higher in the chest, which can feel like you can’t get enough air, even though you’re getting plenty.

A slow breath with a longer out-breath helps the anxious kind settle. If a fast rate at rest doesn’t settle, or breathlessness is new, sudden or comes with chest pain, that needs a doctor rather than a breathing exercise.

• Russo et al., 2017: An overview of research in healthy people suggests slow breathing affects the heart, lungs and nervous system; more study is needed.
• Fleming et al., 2011: A systematic review of 69 studies (breathing-rate data for 3,881 healthy children) found the median breathing rate falls from 44 breaths a minute at birth to 26 at 2 years, with the steepest fall in infants under 2 and a continuing decline into early adolescence.
• Gutierrez et al., 2016: In 38 adults without sleep apnoea studied overnight, breathing rate was higher awake than in any sleep stage, and breathing was most regular in deep (N3) sleep.
• Douglas et al., 1982: In 19 healthy adults, breathing during sleep was more rapid and shallow than during wakefulness, and the amount of air breathed fell, most of all in REM sleep.
• Lehrer & Gevirtz, 2014: Heart rate swings most at around six breaths a minute; this review says a blood-pressure reflex is the likeliest reason.
• Meehan & Shaffer, 2024: In two small studies at six breaths a minute, breathing out longer than in made no difference to heart-rhythm measures.
• Bernardi et al., 2001: Reciting the rosary or a yoga mantra slowed 23 healthy adults' breathing to about six a minute, with stronger, synchronised heart rhythms.
• Laborde et al., 2022: Across 223 studies, slow breathing raised heart-rhythm signs of calm, during practice and after, though that alone doesn't prove a health benefit.
• Balban et al., 2023: Five minutes a day of cyclic sighing lifted mood a little more than mindfulness meditation, in 108 adults.

Questions people ask

Is 22 breaths per minute normal?

For a moment, yes: after stairs, a coffee or a fright, your breathing speeds up and settles again. At rest, 22 is a little above the usual adult range of 12 to 20. Count again after 5 quiet minutes. If it stays high, or you feel short of breath, it’s worth mentioning to your doctor.

Is 10 breaths per minute normal?

It can be. Some calm, fit adults breathe about 10 times a minute at rest, and slow breathing exercises deliberately go lower, to 4 to 10. A naturally slow rate is only a concern if it comes with drowsiness, confusion or new medication, which is a matter for a doctor rather than a breathing exercise.

Does breathing rate change with age?

It falls fast in the first two years: in a review of studies of healthy children, the typical rate dropped from about 44 breaths a minute at birth to 26 by age 2 (Fleming et al. 201162226-X)). It keeps easing down through childhood and reaches the adult range by the late teens.

Can a smartwatch measure my breathing rate?

Many watches and rings estimate it overnight, from tiny changes in your heart rate and movement. The number is most useful compared with your own usual, not with someone else’s. A sudden change from your normal, especially with feeling unwell, means more than any single reading. For a daytime check, counting for a minute works just as well.
