How to do box breathing

Guide · 3 min read

Breathe in, hold, breathe out, hold — four equal counts. A simple, steady pattern you can use almost anywhere, in about a minute.

Box breathing is one of the simplest breathing exercises there is. You breathe in, hold, breathe out and hold again, each for the same count — usually four. Picture tracing the four sides of a square, one side per step. That’s where the name comes from.

It’s often described as a technique taught to athletes and military divers — people who need to stay clear-headed under pressure. But you don’t need a high-stakes job to find it useful. Many people reach for it before a difficult conversation, on a crowded commute, or when their thoughts start to race at night.

How to do it

Sit or stand somewhere you can be comfortable for a minute. Your eyes can be open or closed. Then:

Breathe out fully. Gently empty your lungs so you start from a clean slate.
Breathe in for 4. Inhale slowly through your nose, counting to four in your head.
Hold for 4. Keep the air in, softly, without clamping your throat shut.
Breathe out for 4. Let the air go slowly, counting to four again.
Hold for 4. Pause with your lungs empty before the next breath in.
Repeat. Go around the box for a minute or so, or for as long as it feels comfortable.

That’s the whole exercise. There’s no special posture and nothing to buy. The only thing to get right is keeping the four sides roughly even.

Tips for getting started

Change the count if you need to. If four feels too long, try three. If it feels easy, stretch to five. What matters is that the sides stay equal.
Keep the holds soft. A hold should feel like a pause, not a strain. If you notice your shoulders or jaw tensing, let them drop.
Breathe low. Many people find it more settling to let the breath move their belly rather than their upper chest. A hand on your stomach can help you notice.
Give your mind a job. Counting is part of the point. When your attention wanders — and it will — come back to the next number.
Practise when you’re already calm. A technique that feels familiar can be easier to reach for in a hard moment. A minute a day is plenty.

When to use it

Box breathing is short, quiet and invisible to anyone around you, so it fits into most parts of the day. You might try it:

before a meeting, exam, interview or presentation
when you notice your breathing has become quick and shallow
between tasks, as a reset before the next thing
after a stressful call or message, before you reply
in bed, when your mind won’t switch off

It won’t make a problem disappear, but it can help put a little space between you and the feeling — sometimes enough to choose what to do next. If anxiety shows up often, our page on anxiety has more ideas.

Let the app keep count

Counting in your head works, but it can be hard to keep track when you’re stressed. In yournotalone, box breathing comes with a calm circle that grows and settles with you, so you can simply follow along. Choose 1, 3 or 5 minutes before you start.

If you’d like to try a pattern with a longer out-breath, the app also has 4-7-8 calm and Slow exhale.

A note on safety

Box breathing is gentle, but breath-holding isn’t right for everyone. If you feel light-headed or dizzy, stop and breathe normally. If you’re pregnant, or you have a heart or breathing condition, check with a clinician before trying exercises that involve holding your breath.
