Box breathing vs 4-7-8: which to use when

What’s the difference between box breathing and 4-7-8?

Box breathing and 4-7-8 breathing are both slow, counted breaths with holds. The difference is where the time goes. Box breathing shares it out equally, so it feels even and alert. 4-7-8 spends most of each round holding and breathing out, so it feels heavier and slower.

When should you use each one?

Box breathing keeps you sharp for the meeting. 4-7-8 helps you put the day down.

Box breathing vs 4-7-8: which is better for anxiety?

For a tense moment, box breathing has a little more behind it. In one trial, 5 minutes of it before a stressful test blunted the rise in heart rate and anxiety (McAllister et al. 2026), and a pilot linked one minute of it to less anxiety in real-life tense moments (Riedl et al. 2026).

4-7-8 has fewer tests. In one small crossover of 34 students, it was linked to less stress in women, a result that needs repeating (Avcık et al. 2026). If you’re very anxious, a long hold can feel like too much. Then breathe without holds: a longer out-breath on its own is gentler. There are more ways in breathing exercises for anxiety.

Which is better for sleep?

4-7-8 was made for winding down, and it’s the slower of the two. Neither has been tested as a sleep aid on its own, but slow breathing before bed has: in a 2026 review of 9 studies, people reported sleeping better, though sleep-lab measures were inconclusive (Eide et al. 2026). If the 7-second hold keeps you alert, 4-6 breathing gives you the long out-breath with no hold: in Breathform it’s Unwind, free. There’s more in breathing exercises for sleep.

Which has more research?

Box breathing, by a little. In a lab study, 84 college students tried box breathing, 4-7-8 and two versions of breathing at 6 breaths a minute. The 6-a-minute patterns raised heart rate variability (the small beat-to-beat changes that tend to grow when you’re at rest) more than either, and none of them meaningfully changed blood pressure or mood (Marchant et al. 2025). It was one session each, and the authors note that both techniques have little research behind them so far.

In a month-long trial of 5 minutes a day, box breathing lifted mood within each session, but it didn’t beat mindfulness meditation; cyclic sighing did (Balban et al. 2023). After 4-7-8, heart rate and systolic blood pressure fell in one small before-and-after study with no comparison group (Vierra et al. 2022).

So: pick by the moment, not by the science. Both are reasonable; neither is proven better.

Every study on this page (7)

• McAllister et al., 2026: In 66 adults facing a stress test, box breathing or a long out-breath beforehand softened the rise in heart rate and anxiety.
• Riedl et al., 2026: In a small pilot, one minute of box breathing or cyclic sighing in tense moments eased students' anxiety more than no exercise.
• Avcık et al., 2026: In 34 students, neither 4-7-8 nor alternate-nostril (Nadi Shodhana) breathing changed heart-rhythm measures; stress and mood effects differed between women and men.
• Eide et al., 2026: Across nine studies, slow breathing before bed improved how well people felt they slept, but sleep-lab and tracker results were inconclusive.
• Marchant et al., 2025: In 84 students, six breaths a minute raised heart-rhythm signs of calm modestly more than box or 4-7-8 breathing; none changed mood.
• Balban et al., 2023: Five minutes a day of cyclic sighing lifted mood a little more than mindfulness meditation, in 108 adults.
• Vierra et al., 2022: In 43 healthy young adults, heart rate and blood pressure dipped straight after 4-7-8 breathing, though quiet rest may partly explain it.

What about triangle breathing, the sigh or coherent breathing?

Each of the box’s neighbours does one thing differently. Triangle breathing drops the rest, so there are only three sides and one short hold: a good step down if box feels like work. The physiological sigh is a double breath in and a long breath out, with no counting at all, and it’s the one that lifted mood more than meditation in the month-long trial. Coherent breathing, 5 in and 5 out, is the plain 6-a-minute rhythm that did best on heart rate variability.

Can you combine box breathing and 4-7-8?

Yes, though not in the same minute. They suit different parts of the day. Try box breathing in the corridor before the meeting and 4-7-8 when the light goes off. A day that has both might look like this: 8 rounds of box breathing before the morning call, a few slow breaths at your desk after lunch, and 4 rounds of 4-7-8 in bed.

Try each one here: pick it, press play and follow the shape.

Keep each one comfortable: if a count feels long, shorten it. The pattern is only a guide. What helps is the slower pace and the long, unhurried out-breath.

Questions people ask

Is 4-7-8 the same as box breathing?

They’re different breaths. Box breathing has four equal sides of 4 seconds: in, hold, out, rest. 4-7-8 has three parts: in for 4, hold for 7 and out for 8. It’s slower, and most of each round is the hold and the out-breath, which is why it suits the end of the day.

Which is easier for beginners?

Box breathing, usually, because its holds are shorter. Triangle breathing, with 3.5 seconds a side, is gentler still. If any hold feels like too much, 4-6 breathing (in for 4, out for 6) drops the holds altogether and keeps the long out-breath. Start with a few rounds and add more once the count feels easy.

Can I shorten the 7-second hold?

Yes. Keep the out-breath the longest part and shorten the hold until it feels comfortable. Comfort comes first. A 4-4-8 count, or even 4-2-8, keeps the shape of 4-7-8 with an easier pause. You can lengthen the hold again over a few days if you’d like to, but you don’t have to.

Why does 4-7-8 breathe out through the mouth?

That’s how Dr Andrew Weil, who popularised it, teaches it: a slow, full breath out through the mouth, often with a soft “whoosh”. Through your nose is fine too, if it feels better. The mouth makes the long out-breath easy to hear and to pace. If the whoosh feels too loud in a shared room, breathe out through your nose and keep the count.

How many rounds of each should I do?

For box breathing, 8 rounds is a good start: about 2 minutes. For 4-7-8, Dr Andrew Weil suggests 4 rounds, about 76 seconds, and many people stop there. More isn’t better if the holds start to feel tight. If you want longer, add a few minutes of 4-6 breathing afterwards instead of extra rounds with holds.
