Box breathing
Twelve minutes of four equal parts: in, hold, out, hold. The holds are short and never strained — this is a shape to trace, not a test of lung capacity. Box breathing is the practice to reach for when you need the mind to stop arguing.

The script
Pauses are marked inline. Read at the pace that suits you; the timer below can keep time for you.
Sit upright enough that the ribs can move. Hands on the thighs, eyes closed or lowered.
Breathe normally for a minute and let the last conversation finish in your head. 60 s
Now trace the first side of the square: breathe in for four counts. 20 s
Second side: hold, without closing the throat, for four counts. The air is still; you are not straining. 20 s
Third side: breathe out for four counts, at the same speed as the inhale. 20 s
Fourth side: hold, empty and relaxed, for four counts. 20 s
That is one square. Trace it again, and keep the four sides equal. 120 s
The corners are where attention slips, not the sides. At each corner, check: is the jaw slack? Are the shoulders down? Is the count still honest? 90 s
If four counts on the hold is too long, shorten all four sides to three. Every side changes together — the square stays square. 90 s
Let the counting go and keep the four-part shape for the last two minutes. 120 s
Finish with two ordinary breaths, then open your eyes.

If attention goes
Three things to do when the mind leaves — because it will.
- If the hold turns into a squeeze at the throat, you are holding too long. Cut one count off all four sides.
- If you lose track of which side you are on, start the square again at the inhale. Guessing is more disruptive than restarting.
- If the exhale comes out faster than the inhale, you have found the useful thing to watch. Slow the exhale until the two match.
01The four-part square, in numbers
A square of four counts: four in, four held, four out, four held. That is sixteen counts per cycle — roughly four cycles a minute at a one-second count, which is slower than a resting breath and slower than the six-breaths-a-minute pace of the four-count practice.
For a first attempt use a three-count square: twelve counts per cycle, about five cycles a minute. Stay at three for a full week before you try four, and treat five as an advanced square that most people never need.
02How to hold without closing the throat
The hold should feel like pausing at the top of a staircase, not like bracing underwater. If you can swallow comfortably mid-hold, the throat is open. If the hold produces a pressure in the ears, it is a breath-hold, and that is not what this practice is.
An empty hold is usually easier than a full one. If the second hold is where you struggle, keep that one to two counts and leave the other three sides at four.
03What this practice is good for
Box breathing is a stabiliser: it is used by people who need a steady hand and a quiet line of thought at the same time. It is a poor choice for falling asleep, because the holds keep the mind slightly engaged.
Do not use it while driving or operating anything. The holds make it a poor companion for tasks that need divided attention, which is precisely why it is useful before them.

Questions that come up
Is the hold dangerous?
For healthy adults a four-count hold is not. If you are pregnant, have a heart or blood-pressure condition, or a history of panic attacks, skip the holds and use the equal-parts rhythm without them.
Why does my heart beat harder during the hold?
A brief pause changes pressure in the chest, and the heart responds. This is normal at four counts and is a reason to keep holds short rather than to lengthen them.
Can I use box breathing before a presentation?
Yes, that is its most common use. Six squares — about ninety seconds — is usually enough, and it works better than doing it for ten minutes and arriving late.

Before you begin — Everything here is general information about attention and breathing, offered for educational use only. It is not medical or psychological treatment, and it is not a substitute for care from a qualified professional. If you have a heart or lung condition, a history of panic attacks or trauma, are pregnant, or are being treated for a mental health condition, talk to your clinician before starting breath-holding or long body-scan practice. Stop if a practice makes you dizzy, breathless or distressed.
