Box Breathing vs 4-7-8: Which Should You Use?

The short answer

Box breathing is built to keep you level. 4-7-8 is built to wind you down. No trial has shown that either one outperforms the other, so the difference that matters is the one you can feel, and it comes from where each pattern spends its time.

Box breathing gives every part of the breath the same four seconds: in, hold, out, hold. Nothing is emphasised, and that is the point. An even rhythm is easy to hold on to when the rest of you is not even, which is why it gets taught for the minutes before something demanding rather than the minutes before sleep.

4-7-8 does the opposite. It breathes in for four, holds for seven, and lets go for eight, so nearly half of every cycle is a slow release. A long exhale is the part of the breath most people describe as settling, which is how 4-7-8 ended up as a bedtime pattern while box breathing ended up in briefing rooms and waiting rooms.

If you read no further: run three minutes of each timer above, back to back, today. The one that feels less like work is the one you will still be doing in a month, and a pattern you use twice a week beats a better pattern you abandon on Thursday.

The two patterns side by side

The counts look similar written down. In practice the two feel quite different, because the shape of the cycle is different and so is the amount of it you spend holding still.

The row that decides most people is the share of the cycle spent exhaling. Box breathing spends half of every cycle with the breath held, split between full and empty. That stillness is what makes it feel steadying at a desk, and it is also what makes it a poor bedtime choice for some people, because holding on empty is quietly alerting. 4-7-8 spends more of its cycle in a slow outward flow, and the long hold sits on full lungs, which most people find easier to sit inside than an empty one.

How to do it

The counts do the work. Everything else is comfort. Do both of these sitting down or lying on your back, breathing through the nose if that is available to you, with your jaw and shoulders loose.

Box breathing, step by step

1. Sit with your back supported and your feet flat. Let your hands rest wherever they fall.
2. Breathe out first, all the way, so you are starting from empty rather than from wherever you happened to be.
3. Breathe in through the nose for a count of four. Aim for a smooth fill, not a gulp at the end.
4. Hold for four with the lungs full. Keep the throat open and the face soft. You are pausing, not clamping.
5. Breathe out for four, through the nose or through slightly parted lips, at an even rate.
6. Hold for four with the lungs empty. This is the part people find strange at first. If it feels like too much, cut it to two.
7. Repeat. Three minutes is about eleven cycles. Follow the circle above rather than counting in your head.

4-7-8 breathing, step by step

1. Sit or lie down somewhere you can stay for a few minutes. In bed is fine, and is often the point.
2. Empty your lungs with one unhurried breath out.
3. Breathe in quietly through the nose for a count of four.
4. Hold for seven. Do not brace against it. If seven is a struggle, use four or five and keep the rest of the shape.
5. Breathe out for eight, slowly and steadily. Many people find it easier through slightly parted lips, which gives the air something to push against.
6. Repeat. Three minutes is about nine cycles. Four cycles is the traditional starting dose and is plenty on a first try.
7. If you finish and feel wide awake rather than settled, the hold was probably too long for you. Shorten it and try again tomorrow.

When to use each one, and when not to

Reach for box breathing when

• You have something in the next ten minutes that you would like to walk into steady: a call, a scan, a conversation, a set of stairs.
• You want a rhythm simple enough to keep going while part of your attention is elsewhere.
• You are teaching someone else. Four, four, four, four is the easiest breathing pattern in the world to hand over.
• You are at a desk in the middle of the afternoon and want to reset without getting drowsy.

Reach for 4-7-8 when

• You are already lying down and the goal is to go further down, not to stay sharp.
• Your mind is looping and you want a count long enough to interrupt the loop.
• You want the longest exhale you can comfortably manage without inventing your own pattern.

Use neither when

• You are driving, cycling, swimming, on a ladder, or anywhere a moment of light-headedness would matter. Both patterns hold the breath.
• You are in the middle of a panic surge and holding your breath makes it worse. Breath-holding can imitate the sensations you are trying to escape. A pattern with no hold in it is a better tool in that moment — try extended exhale or cyclic sighing.
• You are short of breath for a physical reason. Paced breathing is not a treatment for breathlessness, and if breathing is hard right now, that is a matter for a clinician rather than a timer.

Before you hold your breath

Both of these patterns include breath-holds, so the same cautions apply to both. Read this once, properly, and then you can forget it.

• Speak to a clinician before practising breath-holds if you are pregnant, or if you live with a cardiovascular condition, uncontrolled high blood pressure, epilepsy, a respiratory condition such as asthma or COPD, glaucoma, or you have had surgery recently.
• If you live with panic attacks, holding the breath can feel like the opening move of one. Box breathing's empty hold and 4-7-8's seven-count are both worth skipping in favour of a pattern that keeps the air moving.
• Practise sitting or lying down. Never while driving, cycling, or in water.
• Stop if you feel dizzy, light-headed, tingly around the mouth or hands, or short of breath. Those are signs to breathe normally for a minute, not signs to push through.
• Shortening a hold is not cheating. A four-second hold you can sit inside calmly is worth more than a seven-second hold you spend braced against.

What the evidence shows

Honestly: less than the internet implies, and almost nothing that separates these two patterns. The only trial we could find that put them head to head is Marchant and colleagues (2025), who compared square breathing — the same 4-4-4-4 pattern this page calls box breathing — with 4-7-8 and with slow breathing at six breaths a minute in 84 college students. Their opening line is blunt: "Square and 4-7-8 breathing are popularly promoted by psychotherapists but have little empirical support." Their result did not favour either of the famous patterns: "Breathing at 6 bpm increased HRV measures more than square or 4-7-8 breathing with small to medium effects," and none of the conditions produced a meaningful change in blood pressure or mood in that single session.

Box breathing also appeared as one arm of Balban and colleagues (2023), who had people do five minutes a day of one of three breathwork protocols for a month and compared them with mindfulness meditation. Box breathing was not the winner there either; the authors report 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." For 4-7-8 specifically, Vierra and colleagues (2022) measured 43 healthy adults aged 19 to 25 before and after three sets of six 4-7-8 cycles. The heart rate variability shift they describe — "low- and very-low-frequency powers significantly decreased" — turned up in the rested control group rather than in the sleep-deprived one, and their own conclusion is carefully hedged: 4-7-8 breathing control "can help participants improve their HRV and BP, particularly in those without sleep deprivation." What both groups did share was simpler: "Both groups had significantly decreased HR and systolic BP (p < 0.05)." Those are immediate, small, single-session physiological shifts in healthy young people, not evidence of a treatment for anything.

The broader picture is kinder. A systematic review by Zaccaro and colleagues (2018) found that "Slow breathing techniques promote autonomic changes increasing Heart Rate Variability and Respiratory Sinus Arrhythmia," which is the general effect both of these patterns are borrowing. What the literature supports is slow breathing. What it does not support is the idea that one branded count beats another. So choose on comfort, and read our fuller summary of what the research says if you want the caveats in one place.

Pick this if…

Still torn? Do both for a week. Box breathing at three in the afternoon, 4-7-8 at eleven at night. They are not competing for the same slot in your day, and running them at the times they suit is a fairer test than running them back to back on a Tuesday morning. If you would rather try a third option, the full timer has five other patterns, including the six-breaths-a-minute pace that came out ahead on heart rate variability in the one head-to-head study above. That study attached a caveat to its own winner, and so do we: "Unexpectedly, breathing at 6 bpm led to mild over-breathing." Slowing the pace tempts people to take bigger breaths to fill the time, which is what causes light-headedness. Keep the breaths small and let the count do the slowing.
