Box breathing
Four equal phases — in, hold, out, hold — that steady the rhythm.
Box breathing is used by soldiers, firefighters and athletes before performing — which is how it earned the name tactical breathing. All four phases are the same length, so there is nothing to calculate; it is enough to imagine your gaze travelling along the four sides of a square. If counting to four is too short or too long, adjust it; the ratio matters more than the number. Eight rounds take just under two minutes, which is the upper limit I recommend with anxiety — more holding does not help.
When to use it
Before a performance, an examination or a difficult conversation. It has a clear structure, which helps when there are too many thoughts.
How it goes
- Breathe in for four.
- Hold for four.
- Breathe out for four.
- Hold for four.
- Eight rounds. If holding is uncomfortable, shorten it to two.
A word of caution
If you have a heart or lung condition, or you are pregnant, talk to your doctor about breath holding; use breathing with a longer out-breath instead.
Why it works
Equal phases give the breath a predictable rhythm that is easier to follow under pressure than an instruction to »breathe deeply«. The structure itself occupies part of the attention that would otherwise go into anticipating. Because the in-breath and out-breath last the same, the exercise calms less strongly than a lengthened out-breath — but it sharpens better, which makes it a better fit just before something where you need to be focused rather than sleepy.
