4-6 breathing

How to do it

1. Sit tall or lie on your back. Let your shoulders and jaw go soft, and close your mouth.
2. Breathe in through your nose for 4 seconds. Let the air travel low so your belly moves a little.
3. Breathe out through your nose for 6 seconds, smooth and even, as if the air were leaving by itself. There's no pause between the two phases.
4. Keep going: 4 in, 6 out. Each cycle takes 10 seconds, which works out to six breaths a minute.
5. Continue for 5 minutes, or 30 cycles. If you lose count, just pick it up again on the next inhale.
6. To finish, drop the count, take a few breaths at your own pace, and open your eyes when you're ready.

What 4-6 breathing is

It's the plainest version of two ideas you'll hear again and again: breathe more slowly than usual, and let the exhale run a little longer than the inhale. There are no holds, no switching nostrils and no special technique.

The numbers are there for a reason. Four plus six is ten seconds a cycle, or six breaths a minute. That's the same pace as coherent breathing 5-5, with the time split differently. Compared with the long exhale 4-8, the gap between the two phases is gentler, which is why almost nobody runs short of air.

Where it comes from

Nobody invented 4-6 breathing, and there's no book or date behind it. We didn't find a tradition that claims it with these numbers, and we'd rather say so than dress it up with a lineage.

What it does have is a place in the lab. When researchers want to test a longer exhale at six breaths a minute, a split of 4 and 6 seconds is one of the options they reach for. It appears that way, for example, in a 2014 study by Lin, Tai and Fan.

What people use it for

Many people use it to settle down after a tense moment, to take a break between tasks, or to wind down before bed. It's discreet: you can do it standing in line, on the bus or in a waiting room.

It's also the most common way in. Someone who has never practiced can learn it in a minute and move on from there to slower patterns or ones with pauses.

What the studies say

The study by Lin and colleagues, with 47 college students, tested four patterns, including the one with 4 and 6 seconds. All of them left participants more relaxed than before they started. The highest heart rate variability didn't come from this pattern, though, but from equal phases at 5.5 breaths a minute.

On the longer exhale, there's no agreement. In 2014, Van Diest and colleagues found, in 30 people, that an exhale more than twice as long as the inhale went with more reported relaxation. A 2021 study of 64 athletes measured more vagal activity when the exhale was somewhat longer. Then again, Meehan and Shaffer looked back at nine studies in 2024: four favored the long exhale, three saw no difference, one preferred equal phases and one the long inhale. Their own two experiments, with 26 and 16 people, found no difference.

More broadly, a 2023 meta-analysis combined 12 controlled trials of breathing practices, with 785 adults. It found a small-to-medium effect on self-reported stress. The authors urge caution, because most of the trials carried a moderate risk of bias.

What it feels like and what to notice

The first few cycles can feel long. Around the second minute the count gets easy and the body tends to loosen: your shoulders drop and the exhale stretches out without effort. A yawn or a sigh in the middle of the practice is normal.

Dizziness, tingling in your hands or face, or feeling short of breath is not. If that happens, stop, breathe the way you always do, and next time take in less air on each inhale.

Variations

• Easier (variation): 3 seconds in and 5 seconds out for a few days. Then come back to 4-6.
• Shorter (variation): the same 4-6 for one minute, six breaths. It's the "One-minute pause" in this guide.
• Longer (variation): the long exhale 4-8, once 4-6 feels comfortable.
• With the mouth (variation): if your nose is stuffed up, breathe out through barely parted lips, without blowing.

Common mistakes

• Taking in too much air. Slow doesn't mean big.
• Pushing the exhale. The air leaves evenly, without force. If you run out before 6, let it go more slowly from the start.
• Lifting your shoulders. If they rise as you breathe in, rest a hand on your belly and let the movement start there.
• Counting faster than the clock. When you're keyed up, seconds shrink. Let the guide on your phone keep time.
• Expecting an instant effect. Give it a few minutes, and a few days, before you judge it.

How often and how long

The guided session lasts 5 minutes. To start, once a day is plenty, and a single minute here and there counts too.

There's no proven dose. What helps most is that it feels comfortable and that you can come back to it: a little, often, beats a lot, once.

Before you start

• If you feel dizzy, tingly or short of breath, stop and breathe normally.
• Don't practice while driving or in water.
• If you're pregnant or have a heart, lung or blood pressure condition, check with your care provider first.
• This is a practice, not a treatment. If anxiety or insomnia is getting in the way of your life, reach out to a professional.
