A ten-minute wind-down you can run in bed
The timer above opens on 4-7-8 breathing set to ten minutes: in through the nose for four counts, hold for seven, out through the mouth for eight. Press Begin, put the phone face down beside you, and follow the sound rather than the screen. If you have used the timer before it remembers the pattern and the length you chose last, so glance at the heading above the circle; the settings icon changes the length, and the row of timers below changes the pattern. Breathing to fall asleep does not need to be more complicated than one pattern and one length.
Most people looking for breathing exercises for sleep arrive on a page like this somewhere between midnight and two in the morning, having already tried lying still and hoping. The reason a paced pattern helps at that hour is not mysterious. A long, unhurried exhale slows the rate at which your heart is beating, and counting gives a loud mind one small, dull job instead of a rehearsal of tomorrow. Neither of those things switches you off. What they do is turn the volume down, and turning the volume down is usually what stands between a tired person and sleep.
Using 4-7-8 for sleep rather than for a daytime reset changes one thing, and that is the length. Ten minutes is a deliberate choice. Three minutes is enough to change how you feel, but at bedtime you want long enough that you stop checking how much is left. Ten minutes is also long enough that plenty of people never reach the end of the session, which is the point. If you drift off at minute six, the timer keeps counting quietly and then stops. Nothing chimes at you, nothing asks you to rate anything.
How to do it
Read this once now, so you are not reading it later with your eyes half shut.
1. Set the room before you start
Lights off or very low. Phone on charge, face down, brightness at its lowest. If the screen is still too bright for a dark room, the night mode in the plan drops the page to near-black with warm, dimmed text; the free timer works exactly the same, it is just brighter.
2. Lie down and take two ordinary breaths
Do not start the pattern cold. Two normal breaths let you notice where you are actually breathing from. If your shoulders are doing the work, rest a hand on your belly and let the next breath push it up instead.
3. Breathe in through the nose for four
Quietly, and not to full capacity. A comfortable three-quarters is better than a heroic lungful, because a full chest makes the hold harder than it needs to be.
4. Hold for seven
Hold with a relaxed throat and a soft jaw, not by clamping down. This is the part most people shorten in the first week, and shortening it is fine.
5. Breathe out through the mouth for eight
Lips slightly parted, a thin steady stream, as though you were fogging a window very slowly. The out-breath should be the longest and quietest part of the cycle. If you run out of air at six, you took in too much at the start.
6. Repeat, and let it get boring
Boring is the goal. Somewhere around the fourth or fifth cycle you stop counting deliberately and the rhythm carries itself. That handover is the moment the practice starts doing something for you.
What the ten minutes actually feel like
The first two minutes are usually the worst, and knowing that helps. Your body is still carrying whatever the evening put into it, the counting feels effortful, and the eight-count exhale feels long. Nothing has gone wrong. Around minute three the pattern stops needing your attention. By minute five most people notice their jaw and shoulders have dropped without being told to. From there the session is mostly maintenance: the circle expands, you follow it, and thoughts arrive and leave without you chasing them.
You do not have to finish. Falling asleep partway through is a success, not an abandoned session. If you are still awake at ten minutes and feel calmer but not sleepy, do not immediately run another round. Lie there for a while in the quiet you just made. A second session usually turns into effort, and effort is the thing you were trying to put down.
When your mind will not stop racing
There is a particular kind of night where the breathing works fine and the thinking carries on regardless. You are counting to eight and simultaneously drafting an email, replaying a conversation, or doing arithmetic on how many hours are left. This is normal and it is not a sign that the technique has failed.
Three things help, in this order. First, give the counting somewhere to live: say the numbers silently on the out-breath only, so the mind has a job at the exact moment it usually wanders. Second, switch to cyclic sighing for a few minutes. It is a double inhale through the nose followed by a long exhale through the mouth, it is faster and more physical than 4-7-8, and the sharpness of the second inhale gives a racing mind something harder to ignore. Then come back to the slower pattern once the edge has come off.
Third, if the thoughts are specific and repeating, stop and write them down. A note on paper or in the dimmest app you have, three lines maximum, then back to the breathing. A mind that keeps rehearsing a list is often just afraid of forgetting it, and in most people's experience ten seconds of writing settles that better than ten more minutes of counting.
And if what is happening is not busy thinking but real anxiety with a physical edge to it, go to the page for anxious moments instead. It is written for that state and carries the helplines that belong with it.
When to use it, and when not to
As a bedtime breathing exercise, this works best as the last thing in an evening that already has some shape to it: lights lowered, screens finished, the same twenty minutes most nights. It is a good fit for the wired-but-tired feeling after a long day, for the night before something stressful, and for the three a.m. waking where you are not distressed, just very much awake. If you cannot sleep and have no idea why, it is also a cheap thing to try before you reach for anything stronger.
It is a poor fit in a few places. Do not use a paced pattern to try to sleep at a time your body is not ready to sleep — breathing will not out-argue jet lag, a late double espresso or a shift pattern. Do not use it as a nightly rescue for months of bad sleep without also talking to a doctor. And do not run it while driving, and not in a bath. It makes people drowsy, which is the whole point, and drowsy is dangerous in both of those places.
Before you try the hold: who should be careful
4-7-8 contains a seven-second breath hold. For most healthy adults that is unremarkable, but a hold is not automatically harmless, and this pattern is not the right starting point for everyone. Skip the hold entirely, or check with a clinician first, if any of the following apply to you.
- You are pregnant.
- You have a cardiovascular condition, an arrhythmia, or uncontrolled high blood pressure.
- You have epilepsy or another seizure disorder.
- You have asthma, COPD, or another respiratory condition, especially if you are having a bad week with it.
- You have had surgery recently, or you have raised intraocular pressure or glaucoma.
- You live with panic disorder, or breath-holding reliably triggers panic for you. Air hunger is a common panic trigger, and a hold can start the exact spiral you are trying to leave.
If any of those describe you, the fix is simple and costs you nothing: use four counts in and six counts out with no hold at all. You keep the long exhale, which is the part that does the work, and you lose the part that carries the risk. Open the technique list from all timers and pick a pattern without a hold. Stop and breathe normally if you feel dizzy, lightheaded or short of breath at any point — that is a signal, not a hurdle to push through.
What the evidence shows
Honestly: less than the internet implies. In a small randomised pilot trial, twenty adults aged twenty to thirty-seven, none of them with a diagnosed sleep disorder, were recorded at home with full polysomnography across two consecutive nights: one after thirty minutes of either slow breathing at five breaths per minute or music listening before bed, and one ordinary evening at home with nothing added. A few sleep measures did shift, but the conclusion the authors themselves reached was that "while some indices pointed to improved sleep quality in both intervention groups, neither condition had robust effects on sleep quality" (Kuula et al., Scientific Reports, 2020). Twenty people is a pilot, not proof.
The measurable short-term effects are easier to demonstrate than any effect on sleep itself. Forty-three healthy young adults, aged nineteen to twenty-five, practised the 4-7-8 pattern for six cycles per set across three sets, with a minute of ordinary breathing between sets. They had been split by how much they habitually slept — under seven hours a night for at least three months, or more than seven — and the pattern moved both: "both groups had significantly decreased HR and systolic BP (p < 0.05)" (Vierra, Boonla and Prasertsri, Physiological Reports, 2022). That is a change in heart rate and blood pressure measured over minutes, in healthy volunteers. It is not a claim about falling asleep faster.
For the racing-mind problem, the clearest trial evidence is on a different pattern. A randomised controlled study in which 108 people were asked to practise for five minutes a day for twenty-eight days, against mindfulness meditation as the comparison, found that "breathwork, especially the exhale-focused cyclic sighing, produces greater improvement in mood (p < 0.05) and reduction in respiratory rate (p < 0.05) compared with mindfulness meditation" (Yilmaz Balban et al., Cell Reports Medicine, 2023). That is about mood and arousal during the day, not sleep at night, which is why cyclic sighing is suggested above as a way to take the edge off rather than as a sleep aid.
So the fair summary is this. Slow, exhale-weighted breathing reliably lowers physiological arousal for a while, and lower arousal is compatible with falling asleep. Whether it makes you fall asleep faster on any given night has not been convincingly shown in a large trial. It is free, it takes ten minutes, and for most people it carries no risk — which is a reasonable basis for trying it, and not a basis for anyone promising you results.
Common questions
Which breathing pattern is best for falling asleep?
There is no single best pattern, and anyone who tells you otherwise is guessing. What the patterns people use at bedtime have in common is a long exhale and a slow overall rate. 4-7-8 is the one this page starts with because the eight-count out-breath is hard to rush. If the seven-count hold bothers you, drop it: four in and six out, with no hold at all, is a gentler pattern that keeps the part that matters.
How long before bed should I do this?
You can do it in bed with the lights already off, which is how most people here use it. If you would rather build a routine, run the ten minutes after you have brushed your teeth and put your phone on charge, so that the practice is the last thing you do rather than something you squeeze in before a final scroll.
What if holding my breath for seven seconds feels like too much?
Then it is too much, and forcing it will make you more alert rather than less. Air hunger and a racing chest are the opposite of a wind-down. Shorten the whole pattern to a four-count in, a four-count hold and a six-count out, or open the technique list and switch to a pattern with no hold in it. The goal is a rhythm you could keep up for ten minutes without effort.
Will breathing exercises fix insomnia?
No. Nothing on this site treats insomnia. For insomnia that has run for months, the treatment sleep clinicians reach for first is cognitive behavioural therapy for insomnia: an American Academy of Sleep Medicine review records that "recent guidelines and statements that address comprehensive treatment for chronic insomnia uniformly support the use of cognitive-behavioral therapies (CBTs) as first-line treatment for the disorder" (Edinger et al., Journal of Clinical Sleep Medicine, 2021). That means a structured programme run with a clinician or through a validated course, not a breathing pattern. A wind-down can be a useful part of an evening, and it is free and harmless for most people, but if you have been sleeping badly for months, please raise it with a doctor rather than working through it alone.
Can I do this lying on my side?
Yes. Any position you can actually fall asleep in is the right position. On your side, the belly usually moves more easily than the chest, which suits a slow pattern. The only thing worth avoiding is propping yourself up on an elbow to watch the circle on the screen. Listen to the cues instead and let your eyes close.
What should I do if I wake at three in the morning?
Use the same ten minutes, but expect less of them. A three a.m. waking usually comes with a jolt of alarm about the hours you have left, and the breathing is there to take the edge off that alarm rather than to switch you off. Keep the lights low, keep the screen dim, and if you are still wide awake after twenty minutes, standard sleep advice is to get up, do something dull in low light, and come back when you feel drowsy.
