What Is the Average Breathing Rate During Sleep? What Counts

Most healthy adults breathe about 12 to 19 times a minute while they sleep, and the average sits near 15. That number stays steady from night to night, which is exactly what makes it useful.

This guide covers what counts as normal, how sleep stages shape your breathing, what pushes the rate up or down, and how to track it at home without getting fooled by a gadget.

Key Takeaways

Healthy adults breathe roughly 12 to 19 times a minute asleep, with an average near 15.
Your rate changes very little between sleep stages, but each breath gets smaller, so total air moved falls by roughly 14 to 19%.
Age, body weight, sex and illness all nudge the number, and a jump above your own baseline is the thing to watch.
Rate alone can’t spot sleep apnea, because apnea shows up as pauses and oxygen dips.
Home trackers estimate breathing rate well enough for trends, so compare weeks, not single nights.

What’s The Average Breathing Rate During Sleep?

One large wearable study put numbers on it. Across healthy adults, 90% of nighttime breathing rates fell between 11.8 and 19.2 breaths per minute, with an average of 15.4 (Natarajan et al., 2021).

The researchers checked their method against sleep studies and found an average error of under half a breath per minute. So treat anything from the low teens to about 19 as typical.

Breaths Per Minute By Sleep Stage

Sleep stage barely moves the number. One study that tracked each stage found about 16.6 breaths per minute awake, 15.2 in light sleep, 15.1 in deep sleep and 16.4 in REM sleep (Zhang et al., 2014).

A study of 38 adults without sleep apnea agreed on the direction: breathing was faster awake than in any sleep stage, and it varied the least in deep sleep (Gutierrez et al., 2016).

Why You Move Less Air Even When The Rate Holds

The rate stays put, but each breath shrinks. In 40 healthy middle-aged adults, minute ventilation dropped 14 to 19% from waking to sleep because tidal volume fell, with no significant change in breathing rate (Krieger et al., 1990).

REM sleep is the extreme case. In 19 healthy adults, tidal volume in REM fell to 73% of the waking level (Douglas et al., 1982).

What Changes Your Breathing Rate At Night

Age, Weight And Sex

Your rate drifts down slightly as you get older. It’s also lowest around a BMI of 25 and rises at lower and higher weights, and women under 50 run a bit higher than men, with no difference after that (Natarajan et al., 2021).

Illness And Sleep Position

Infection is the biggest everyday mover. In the same wearable data, many people with COVID-19 had at least one night with a rate 3 breaths per minute above their usual (Natarajan et al., 2021).

A home radar tracker study of 37 healthy adults saw the same thing on a smaller scale: nightly averages stayed consistent, and every big deviation matched a self-reported illness (Toften et al., 2022).

Medications, Lung Disease And Altitude

Opioids and some sedatives can slow breathing, so ask your pharmacist if a new prescription affects sleep. Lung conditions such as asthma and COPD tend to raise the rate as your body compensates, and high altitude does the same because there’s less oxygen in the air.

When Your Breathing Pattern Signals A Problem

A normal rate doesn’t clear you of sleep apnea. Apnea is about pauses of ten seconds or more and the oxygen dips that follow, and our guides on the signs and symptoms of sleep apnea and on sleep apnea and your health cover what to look for.

It’s also common. In a Swiss study of 2,121 adults aged 40 to 85, moderate-to-severe sleep-disordered breathing showed up in 23.4% of women and 49.7% of men (Heinzer et al., 201500043-0)).

Hypopnea is the milder cousin: the airway narrows and airflow drops without stopping. It still breaks up your sleep, and over years the risk adds up, since severe untreated breathing disorders were linked to about three times the risk of death from any cause in an 18-year follow-up (Young et al., 2008).

If that worries you, read whether sleep apnea can kill you.

How To Measure Breathing Rate While You Sleep

Sleep Studies

An in-lab sleep study is the gold standard. Sensors track brain waves, breathing effort and airflow, and oxygen all night, so a clinician sees rate and pauses together.

Wearables And Bedside Trackers

Home devices estimate rate in different ways, and their accuracy varies. Wearables that read your pulse averaged about half a breath per minute of error in one study (Natarajan et al., 2021), and a bedside radar sensor averaged about 0.18 but captured breathing only 84% of the time (Toften et al., 2022).

A chest-worn accelerometer was less precise, with a typical gap of 1.8 breaths per minute (Ryser et al., 2022).

Build a personal baseline over a couple of weeks and look for departures from it. Since healthy nightly averages are so consistent, a sustained rise is more meaningful than a single odd night.

You can also count by hand. Lie still, count your breaths for a full minute, and expect the number to run a little higher awake than it does in sleep.

How To Support Healthy Breathing During Sleep

Start with the basics that keep your airway open.

Side sleeping helps many people, and clearing a blocked nose can help too, whether through a nasal strip or by treating allergies. Breathing through your mouth at night is its own issue, covered in our guide to mouth breathing during sleep.

Cut back on alcohol close to bedtime, since it relaxes the throat muscles. If extra weight is part of the picture, our guide to lifestyle changes for sleep apnea is a practical place to begin.

When those steps aren’t enough, talk to your doctor about a sleep test. For confirmed sleep apnea, CPAP therapy is the standard treatment, and oral appliances and surgery are options in some cases.

Frequently Asked Questions

Most healthy adults breathe about 12 to 19 times a minute asleep, with an average near 15. Your own baseline matters more than the population range.

It sits just above the typical range, so one night isn’t cause for alarm. If your rate stays above your usual baseline for days, or comes with fever, cough or breathlessness, check in with your doctor.

The rate changes very little, but each breath is shallower, so the total air you move drops by roughly 14 to 19%. That’s normal, and it’s one reason a stuffy nose or a narrow airway matters more at night.

Good ones are accurate to within a breath or two per minute, which is plenty for tracking trends. Don’t use them to diagnose anything, and expect gaps on nights when the sensor shifts.

Not reliably. Apnea shows up as pauses and oxygen dips, so snoring, gasping and daytime sleepiness are better clues, and a sleep test is how you confirm it.

Your Baseline Is The Number To Watch

Pick one tracker, wear it for two weeks, and note your usual range. After that, a sustained rise or a night of long pauses tells you far more than any chart average.

If you see that, or if a partner notices gasping, mention it to your doctor and ask about a sleep study.
