The patterns people reach for at a desk are not the ones they reach for at night, and the difference is easy to describe: at night the out-breath is stretched, and at a desk everything is even.
This page is about why that is, what the holds are doing in the even patterns, and what a session at a desk actually looks like.
Box breathing is the pattern most associated with working attention, and it is the most symmetrical one there is: in, hold, out, hold, all the same length. Nothing about it is stretched in either direction.
That symmetry is the useful property. A pattern with a long exhale asks you to keep going past the point where the breath wants to turn around, and that is a thing you have to attend to. An even pattern asks for nothing except the count, which is the smallest possible task.
Resonance breathing is the other even one — five seconds in, five out, no holds at all. It is the same idea with even less structure.
Box breathing holds twice per cycle: once on full lungs and once on empty. Those two holds are what make it a box rather than a wave.
Mechanically the hold is the part where nothing is happening, and that is exactly what it contributes. In a pattern with no holds the breath is always either rising or falling, so there is always something to follow. The holds put two flat sections into every cycle — two moments with no movement to track.
Whether you find that steadying or fidgety is personal, and it is the honest reason to try both box and resonance rather than to be told which one is the focus pattern.
A box cycle is sixteen seconds at four-second sides, so four rounds is a little over a minute. That is the default here and it is a realistic length for something done between two other things.
Longer sides make a slower session: seven seconds a side is a twenty-eight second cycle, and four of those is nearly two minutes. The sides are adjustable from four to seven precisely because the right length is the one you will actually finish.
Nothing in these patterns is visible from the outside if you breathe through your nose and do not force anything. There is no posture to adopt and no sound to make.
The timer is the part that is visible, which is why it is worth setting the pace before you start rather than during. Press Begin and you can look away from it entirely — on a phone it carries the pattern with sound and haptics, and the screen can be off.
The timer below is the app, running in this page. It opens on box breathing at four-second sides.
The pattern In 4 s · Hold 4 s · Out 4 s · Hold 4 s
Box breathing is even, and 4-7-8 is built around a long exhale and a seven-count hold. The even pattern asks less of you while you are doing something else; that is the whole of the difference.
Four rounds of box breathing is a little over a minute at the default. Set the number before you start — the useful length is the one you will finish.
They add two flat sections per cycle rather than effort. If holding on empty is uncomfortable, resonance breathing is the same evenness with no holds at all.
Through the nose, without forcing, there is nothing to see or hear. The timer is the visible part, so set it before you begin.
It is whatever you use it for. The patterns are defined by their timing, not by an occasion — the same ones turn up under focus, stress and sleep.
On your phone it runs with sound and haptics, and it works with no connection at all.
