Box breathing (4-4-4-4)
Four equal phases – in, hold, out, hold. The fixed count gives your mind something to do and your body a calm rhythm. Known from training for first responders, useful before presentations and exams.
How it works
- 1Sit comfortably, hands on your thighs.
- 2Breathe in through your nose for 4 seconds – the circle grows.
- 3Hold for 4 seconds without straining.
- 4Breathe out for 4 seconds – the circle shrinks.
- 5Hold empty for 4 seconds. Then start again, for about 3 minutes.
How it works
Box breathing slows you to about four breaths per minute. Slow breathing raises heart rate variability, a sign that the rest-and-digest nerve is at work. Add the effect of structure: counting leaves little room for rumination.
An honest take
There are only a few studies on box breathing specifically; the evidence comes mostly from research on slow breathing in general (review: Laborde et al. 2022). If holding feels unpleasant, the physiological sigh is the gentler choice.
Frequently asked questions
4 seconds is too long for me – what now?
Start with 3 seconds per phase. The steady rhythm matters, not the length.
Box breathing or 4-7-8?
Box breathing keeps you calm and alert at once – good during the day. 4-7-8 breathing with its long exhale suits falling asleep better.
Does it cost anything?
No, it is free and needs no account.
