Box breathing, step by step

Four counts in, four held, four out. Here is how box breathing works, a gentler version to start with, and when to reach for 4-7-8 instead.

What is box breathing?

Box breathing is breathing in equal counts. You breathe in for four seconds, hold for four, breathe out for four and hold again for four. Draw it and you get the four sides of a square, which is where the name comes from. It is also called square breathing or 4-4-4-4 breathing.

It is often associated with people who need to stay steady under pressure, such as soldiers, police officers and athletes, because it asks for nothing but a few minutes and a count. You can do it at a desk, on a train or in bed, and nobody around you will notice.

How to do it

1. Sit upright and let your shoulders drop. Feet on the floor, hands in your lap. Close your eyes if you like.
2. Breathe out fully through your mouth, so you start empty.
3. Breathe in through your nose for four seconds. Let the belly move first, then the chest.
4. Hold for four seconds. Keep the throat soft; you are pausing, not straining.
5. Breathe out slowly for four seconds, through the nose or gently through the mouth.
6. Hold empty for four seconds, then begin again.

Four to six rounds take about a minute and a half. Three to five minutes is a good session.

A gentler version: in, hold, out

The second hold, with empty lungs, is the part most beginners find uncomfortable. If it makes you tense, drop it: breathe in for four, hold for four, breathe out for four, and start again. That is the version Samurai Zen uses for its Box Breath, fifteen rounds of 4-4-4, about three minutes, with spoken cues so you can keep your eyes closed.

If four seconds feels long, use three. The counts matter less than keeping them equal and the breath smooth.

The 4-7-8 breath for sleep

Where box breathing is even, 4-7-8 is lopsided on purpose: breathe in for four seconds, hold for seven, breathe out for eight. The long exhale is the point. Many people find it settling at the end of the day, which is why it is often suggested for falling asleep.

1. Breathe in quietly through the nose for four.
2. Hold for seven.
3. Breathe out through the mouth for eight, slowly and completely.

Start with four rounds and build up. Samurai Zen’s 4-7-8 Deep runs ten rounds, a little over three minutes.

Which one, when

• Before a meeting, a call or a hard conversation: box breathing. It is even and alert.
• In bed, or when you can’t switch off: 4-7-8. The long exhale slows you down.
• On a slow, foggy morning: a brisk cycle, such as three in, one held, three out.

Common mistakes

Forcing the breath is the most common one. Breathwork should feel like a slow walk, not a sprint; if you are gasping at the end of a hold, shorten every count. The second is breathing high in the chest with raised shoulders. Put a hand on your belly and let it move first. The third is counting too fast. Use a clock, a metronome or a guided cue for the first few sessions until four seconds feels like four seconds.

A note on safety

Breathing exercises are not medical treatment. If you feel dizzy or light-headed, stop and breathe normally. If you have a heart or lung condition, are pregnant, or have been told to avoid breath-holding, talk to a doctor first and skip the holds.

Doing it on your iPhone

Samurai Zen has three timed patterns: Box Breath (4-4-4), 4-7-8 Deep and Energize (3-1-3). A glass circle grows and settles with each phase, a voice tells you when to breathe in, hold and breathe out, and soft haptics mark the last seconds of each phase. All three are free, and they work without a connection.
