How to do it
- Lie on your back or sit with your back supported. Close your mouth, unclench your jaw and let your hands rest wherever they fall.
- Breathe in through your nose for 4 seconds, without filling up all the way. This count stays the same for the whole session.
- Breathe out through your nose for 6 seconds in a thin, even stream, then breathe in again with no pause. Do the first three cycles this way.
- From the fourth cycle, the exhale lasts 6.5 seconds. Every three cycles it adds another half second: 7, 7.5, 8, 8.5, 9 and 9.5. The guide keeps count; you just follow the sound or the curve.
- On cycle 25, a little before the five-minute mark, the exhale reaches 10 seconds and stops growing. Stay at 4 and 10 for the rest of the time.
- The full session lasts about 8 minutes, close to 39 cycles. If an exhale feels too long, take one normal breath and rejoin the guide where it is.
- To finish, drop the count and let your breathing find its own pace. If you're in bed, stay just as you are.
What it is
It's a slow breath in which only one thing changes: how long the exhale lasts. The inhale stays at 4 seconds. The exhale starts at 6 and grows by half a second every three cycles, up to a ceiling of 10. There are no holds, and all the air moves through the nose.
It begins exactly like 4-6 breathing, at six breaths a minute, and ends at 4 and 10, with 14-second cycles: a little over four breaths a minute. Unlike the long exhale 4-8, you don't pick a fixed ratio here. Each change is so small, half a second at a time, that you barely notice it from one cycle to the next.
Where it comes from
Nobody invented this sequence, and it has no traditional name. We built it for this site from a simple idea you hear in a lot of breathing classes: a long exhale is easier to reach in steps than all at once. We couldn't find a single origin for that idea, so we don't credit one.
There is a modern precedent that can be documented. Guided-breathing devices such as RESPeRATE track your breathing with a sensor and play two tones, one for the inhale and one for the exhale. According to the manufacturer, the exhale tone gradually gets longer to lead you toward a slower pace. The principle is the same, with one difference: this guide doesn't measure you. It follows a fixed plan.
What people use it for
Many people use it in bed or in the last half hour of the day. An exhale that grows by itself feels like walking down a staircase: there's nothing to decide, only something to follow.
It also suits anyone who wants to work up to long exhales and finds 4-8 too much right away. Here you pass through 6, 7 and 8 seconds first, and you can stay on whichever step feels good. Others choose it because counting the same numbers over and over bores them, and a slow change holds their attention.
What studies say
We found no studies of this exact sequence. What exists covers its relatives: slow breathing, and exhales that are longer than inhales.
On the ratio, results disagree. A 2014 study of 30 people found more self-reported relaxation when the exhale lasted longer than the inhale. In 2024, another study compared a double-length exhale with an equal one, at six breaths a minute, in a group of 26 people and then in a second group of 16. It found no difference in heart rate variability.
On devices that stretch the exhale, a 2012 review pooled eight trials with 494 adults and saw a small drop in blood pressure. When the five trials tied to the manufacturer were left out, the effect disappeared. The authors called for longer, independent trials.
On sleep, a 2019 trial with 64 healthy young adults compared 15 minutes of slow breathing every evening for 30 days with the same time spent on social media. The breathing group reported better sleep quality. That's one study, based on a questionnaire, using a different pattern. The evidence is limited.
What it feels like and what to notice
The first few minutes feel like any 4-6 breathing. Around the halfway point, the exhale starts asking you to slow the flow of air from the very first second. It's normal for your body to feel heavier, to yawn, or to lose count. That's what the guide is for.
It's also normal not to reach 10 seconds the first few times. If you feel an urgent need to breathe in, if you finish the exhale by squeezing your belly, or if you get dizzy or tingly, you've passed today's limit. Breathe normally and go back a step.
Variations
- Easier: stop on the step that feels comfortable, say 4 and 7 or 4 and 8, and keep going there on your own. Reaching 10 is optional.
- Shorter: do only the first 5 minutes. By then the exhale has already traveled the whole way from 6 to 10 seconds.
- Longer: when the session ends, stay at 4 and 10 for a few more minutes on your own, if it feels good.
Common mistakes
- Taking in more air so the exhale will last. The inhale is still an easy 4 seconds; what changes is how slowly you let go.
- Letting most of the air out in the first few seconds and then waiting. Spread the exhale out from the start.
- Pushing with your belly at the end to make the count. If you have to push, that step is too long today.
- Treating 10 as a goal. The session counts just as much if you stay at 8.
- Carrying on when you feel dizzy or tingly. Those are signals to stop and breathe normally.
How often and how long
One 8-minute session at the end of the day is a realistic practice. If you repeat it over several nights, the longer steps usually start to feel more comfortable. There's no proven dose: studies of slow breathing use very different lengths and schedules.
If you don't have 8 minutes one night, do the first three or four. And if you've been sleeping badly for weeks, breathing can keep you company, but it's worth talking with a health professional.
Before you start
- If you feel dizzy, tingly or short of breath, stop and breathe at your normal pace.
- Don't force the exhale longer or empty yourself completely. Stay at a comfortable count.
- Don't practice while driving or in water: it can make you sleepy.
- If you're pregnant or have a heart, lung or blood pressure condition, check with your care provider first.
Frequently asked questions
Does the lengthening breath help you sleep?
Many people use it in bed because it's slow, quiet and asks for no decisions. A 2019 trial found better self-reported sleep quality after a month of slow breathing in the evening, but it didn't test this pattern. We can't promise it will put you to sleep. If insomnia lasts for weeks, talk with a health professional.
What if I can't exhale for 10 seconds?
Stay at the longest count that feels comfortable and keep going there. Reaching 10 isn't the point. Over several days, many people find the longer steps take less effort.
Why does the exhale get longer and not the inhale?
Because many people find the exhale the most restful part of the cycle, and stretching the inhale tends to make you take in too much air. That said, studies don't agree on whether a longer exhale adds anything to simply breathing slowly.
How long does a session take?
The guided session runs about 8 minutes, close to 39 cycles. The exhale reaches 10 seconds a little before the five-minute mark and stays there. You can stop earlier whenever you like.
How is it different from 4-7-8 breathing?
4-7-8 has a 7-second hold, breathes out through the mouth and is done for four cycles. This one has no holds, stays in the nose and changes gradually over several minutes. If holding with your lungs full bothers you, this one tends to feel gentler.
