Alternate Nostril vs Box Breathing: Which Should You Use?
Two of the most popular calming breaths in the world, from two very different places. One comes from the yoga tradition and is several thousand years old. The other is taught to soldiers.
They do overlap — both slow you down, both work. But they feel completely different to practise, and after twenty years of teaching I’ve noticed people tend to have a strong preference for one and mild bafflement at the other.
Here’s how to know which one is yours.
The quick answer
- Alternate nostril breathing (nadi shodhana) — soft, balancing, slightly ceremonial. Best for winding down, settling before meditation, and sleep.
- Box breathing — structured, steady, no hands involved. Best for focus, pressure, and doing discreetly in public.
If you want to be calm and alert, box breathing. If you want to be calm and soft, alternate nostril.
Alternate nostril breathing (nadi shodhana)
You close one nostril, breathe through the other, then swap. That’s the whole idea. In yoga it’s called nadi shodhana — “channel cleaning” — and it’s traditionally done before meditation to settle the mind.
How to do it:
- Sit comfortably. Rest your left hand wherever it likes.
- With your right hand, bring your thumb to your right nostril and your ring finger to your left. (Index and middle fingers can rest on your forehead or curl in — either is fine.)
- Close the right nostril with your thumb. Breathe in through the left, slowly.
- Close both briefly. Then release the right and breathe out through it.
- Breathe in through the right. Close both. Release the left and breathe out through the left.
- That’s one round. Do five to ten.
Keep it gentle. No forcing, no straining, and if you feel light-headed, stop and breathe normally. It should feel like being smoothed out, not like exercise.
What it feels like: unhurried and slightly ritualistic. The hand position gives your fidgeting something to do, which is a genuine benefit for restless people. Many find it the single most reliable way to settle before sitting.
Best for: the wind-down before bed, before meditation, and anyone who finds counting techniques irritating.
Box breathing
Equal parts, four ways round, no hands.
- Inhale through the nose for 4.
- Hold for 4.
- Exhale for 4.
- Hold empty for 4.
- Repeat for three to five minutes.
What it feels like: orderly. It’s a bit like a metronome for the nervous system — the appeal is precisely that it’s predictable, and it leaves you steady and awake rather than drowsy. That’s why it’s used before high-pressure situations rather than before bed.
More here if you want it: mastering box breathing and how long to do it.
Best for: focus, nerves before something demanding, and practising invisibly in a meeting or on a train.
Head to head
| Alternate nostril | Box breathing | |
|---|---|---|
| Origin | Yoga (pranayama) | Modern, military-popularised |
| Hands needed | Yes | No |
| Counting needed | No | Yes |
| Breath holds | Brief | Yes, longer |
| Leaves you | Soft, settled | Steady, alert |
| Do it in public? | Not discreetly | Easily |
| Best time | Evening, pre-meditation | Daytime, pre-pressure |
| Evidence base | Modest | Modest, a little stronger |
For sleep → Alternate nostril. Box breathing’s holds keep you slightly too alert.
For focus → Box breathing, clearly. It’s built for it.
In public → Box breathing, unless you’re comfortable holding your nose on the 8:15.
For beginners → Box breathing is easier to learn (it’s just counting), but alternate nostril is easier to keep doing, because the hand position occupies the restlessness that makes people give up. Try both for a week.
If you dislike breath holds → Alternate nostril, or drop box breathing’s holds entirely and breathe in for four, out for six.
An honest word about the evidence
You’ll find confident claims that alternate nostril breathing “balances the left and right hemispheres of your brain.” I’d hold that loosely. There is a real phenomenon called the nasal cycle — your nostrils genuinely do take turns being dominant through the day — and there’s some research linking nostril dominance with subtle shifts in arousal. But the hemisphere-balancing story is a considerable leap beyond what’s been shown.
The studies on alternate nostril breathing are mostly small, and they tend to look at blood pressure, attention and stress markers over short periods. Promising, not conclusive.
What we can say with reasonable confidence about both techniques: slow breathing, particularly with a longer out-breath, reliably settles the nervous system. That’s the active ingredient in each of them, and it’s the reason they work.
Which is oddly freeing. Pick the one you’ll actually do. The mechanism is largely the same; the difference is whether the ritual suits you.
If you’d like more options, I’ve collected five proven breathing exercises and compared box breathing with 4-7-8 too.
Can you combine them?
Yes, and it’s a lovely sequence:
- Alternate nostril first — five rounds to settle and arrive.
- Then sit — five or ten minutes of ordinary mindfulness.
That’s the traditional order, and it’s traditional because it works. The nostril breathing gives a restless mind something to do while it comes down, so that when you stop, you’re already halfway there.
Box breathing doesn’t sequence into meditation quite as nicely — the counting keeps a part of you busy. Use it on its own, when you need it.
The part nobody puts in the article
You now know two good techniques. So do most people. Very few are doing either one next Thursday.
The gap between knowing a breathing exercise and having a practice is almost entirely about rhythm and company — a set time, and somebody who notices. Not more information.
That’s why I sit with other people every morning rather than alone. In the Daily Mindfulness Club I guide a short live session each weekday at 7:30am UK time — a small friendly group, a real person guiding rather than a recording, rooted in ACT so it’s about living toward what matters to you rather than only feeling calm.
No card needed. Come and breathe with us one morning.
Frequently asked questions
Which is better, alternate nostril or box breathing? Neither outright. Alternate nostril suits winding down, sleep and pre-meditation; box breathing suits focus, pressure and practising discreetly.
Is alternate nostril breathing good for anxiety? Many people find it calming, and slow breathing with a long out-breath does reliably settle the nervous system. The specific research is limited and mostly small-scale, so treat strong claims carefully. For the psychological side of anxiety, you might like the quicksand metaphor.
How long should I do alternate nostril breathing? Five to ten rounds, or about five minutes. Stop sooner if you feel light-headed.
Can I do alternate nostril breathing with a blocked nose? Not comfortably, and it’s not worth forcing. Use box breathing, or breathe in for four and out for six, until you’re clear.
Does alternate nostril breathing balance the brain’s hemispheres? That’s a popular claim that outruns the evidence. The nasal cycle is real; the hemisphere-balancing explanation is not well established. The calming effect is real regardless.
Which is better before bed? Alternate nostril. Box breathing’s holds tend to leave you a touch too alert.
In short
Evening, softness, before meditation → alternate nostril. Daytime, focus, under pressure → box breathing.
Both work by the same underlying route: slow the breath, lengthen the exhale, settle the system. So the real question isn’t which is superior. It’s which one you’ll still be doing in a month. :)
