Breathwork
Box breathing (square breathing), step by step.
Box breathing, also called square breathing or four-square breathing, is the pattern with four equal sides: inhale for four counts, hold for four, exhale for four, hold for four again. The evenness is the point. Each side carries the same weight, which gives a busy mind one steady thing to follow.

The pattern
- Inhale through the nose for 4 counts.
- Hold for 4 counts, lungs full.
- Exhale for 4 counts.
- Hold for 4 counts, lungs empty.
One cycle · 16 counts · session runs 5 minutes
There is nothing hidden in it. The pattern asks for four equal sides and lets the counting do the work: while you are tracing the square, there is less room for everything else.
Step by step
Sit with a long back and loose shoulders, or lie down if you prefer. Let a normal exhale empty the lungs, then begin:
- Inhale through the nose, counting one, two, three, four.
- Hold with the lungs full, throat soft, for four more.
- Exhale through the nose, slowly, for another four.
- Hold with the lungs empty for four, and start again.
Many people trace a square with their eyes or a finger as they count, one side per phase. In Reed the orb does that work: it swells on the inhale, stays still through the holds and settles on the exhale, so all you have to do is follow it.
Try it here
A few rounds of the square, right in the browser. Press start and follow the circle: it grows on the inhale, holds, and settles on the exhale. Stop whenever you like.
Nothing is recorded here. In Reed the same session runs with tones and haptics, and asks how you feel before and after.
When to reach for it
Reach for it before something that needs a steady hand: a difficult conversation, or the minutes before you walk into a room. In Reed it is the first session in the library, five minutes with the orb carrying the count.
Variants of the count
Four to a side is the classic, but the square comes in other sizes, and none is more correct than another:
- Three to a side. A smaller square for starting out, or for days when the holds feel long.
- Four to a side. Reed's session: five minutes at this count.
- Five or six to a side. Only once four has become fully comfortable; the feeling should stay calm, not effortful.
If you would rather lengthen the exhale than keep the sides equal, look at 4-7-8 breathing. And if you want the same square ratio while alternating nostrils, that is alternate nostril breathing.
Common mistakes
- Gulping the inhale to reach four. The inhale is spread across all four counts; if you have air to spare at the end, you went too fast.
- Clamping the throat on the holds. Holding means the air stops moving, not that you block it; the neck and face stay relaxed.
- Lifting the shoulders on the inhale. The air goes down towards the belly and the ribs open sideways.
- Counting faster and faster. If the count speeds up, pause, breathe normally for a moment, and pick it up again.
Practising safely
Box breathing is a gentle pattern, though the holds can feel unfamiliar at first. Practise sitting or lying down somewhere safe, never while driving or in water, and stop if you feel dizzy or unwell. If you are pregnant, or have a heart condition, high or low blood pressure, a respiratory condition, epilepsy, or experience panic attacks, check with a doctor before you begin. Reed is for general wellbeing; it is not medical advice or treatment.
Five minutes, guided by a single orb that swells, holds and settles with the square. You mark how you feel before and after, and Reed shows you the shift.

Questions
Why is it called box breathing?
The four phases have equal length, so the breath traces the four sides of a square: in, hold, out, hold. The name is the shape.
Is box breathing good for focus?
The even count gives the mind a track to run on, which is why it is Reed's focus pattern. Rather than promising a result, Reed measures your own state before and after, so you can see what it does for you.
What if the holds feel too long?
Stop and breathe normally; a pattern should never feel like a struggle. With practice the four counts tend to soften, but comfort comes first.
Is box breathing free in Reed?
Yes. Every session in Reed is free and unlimited, with no account. Reed Pro adds personal insights on top; it never locks a session.
How many rounds of box breathing should I do?
There is no correct number. A few rounds already change the rhythm; Reed's session runs five minutes, about eighteen rounds, and is meant to fit before anything. Start short and extend only while it stays comfortable.
Can I do box breathing lying down, or anywhere?
Yes, lying down or sitting, at home, on a train or before a meeting. The only requirement is a safe place where nothing else needs your attention, and never while driving or in water.
Can I use this page as a box breathing timer?
Yes. The timer above runs the four-count square in your browser. You don't need to download anything, and nothing is recorded. Reed's session adds tones, haptics and the before-and-after check-in.
