Breathing techniques all do one of four jobs: calm you down, keep you sharp, get you to sleep, or reset you in seconds. Once you know which job you need, the choice is easy, because for each job there is one pattern that most people can hold. The counts are below, with the moment each one is for. If you only learn one, learn calm breathing: a comfortable breath in for about 4 seconds, a slow breath out for about 6, no holds. Every other technique on this list is a variation on that longer breath out.

Why do breathing techniques work at all?

Because the breath is the one part of the stress response you can change on purpose. Stress makes breathing fast, high and shallow, and the body reads that as more danger. A slow breath with a longer exhale sends the opposite signal: your heart slows a little on every breath out, through the "rest and digest" side of the nervous system, and the rest of the body follows. Breathing: how it works is the plain explainer, and why a longer exhale calms you down is the mechanism in one page.

Belly breathing: the foundation

Also called diaphragmatic breathing. Lie down or sit back, put one hand on your belly and one on your chest, and breathe so that the lower hand moves more than the upper one. There is no count; the point is to move the breath down out of the chest, where stress puts it. Two minutes of this is a technique on its own, and it is the base the others sit on. If a pattern below feels tight, come back to this.

Calm breathing: the everyday one

In through the nose for 4, out through the nose or soft lips for 6, no holds, for two to five minutes. It is the easiest to remember and the hardest to get wrong, and the only rule is that the breath out is longer than the breath in; 4 in and 5 out is fine if 6 feels long. It suits ordinary stress, a tight chest after a fast day, the ten minutes before a hard call. Calm breathing, step by step.

The physiological sigh: the fastest reset

In through the nose, then one more short sip of air on top, then one long, slow breath out through the mouth. One to three of them. The second sip reopens the small air sacs in the lungs, so the long exhale clears more than a normal breath would, which is why it works in seconds rather than minutes. A 2023 study of 108 adults found five minutes a day of this, called cyclic sighing, gave the largest daily improvement in mood of the methods compared. It is for the first seconds of panic, the moment after bad news, the sharp intake of breath at the top of the stairs. Then move to calm breathing. Physiological sigh, step by step.

Box breathing: calm but alert

In for 4, hold for 4, out for 4, hold for 4. The two holds slow you down without leaning toward sleep, and four equal sides are easy to count under pressure. It suits anxious anticipation: before a meeting, a presentation, a difficult conversation. If holding your breath feels uncomfortable, make every side 3, or pick a pattern with no holds. Box breathing, step by step, and box breathing before a meeting for the ten minutes before.

Resonant breathing: the long, even one

About 5.5 seconds in and 5.5 out, no holds, which is between five and six breaths a minute. Nothing changes from one breath to the next, so it is the easiest to keep up for ten minutes and the easiest to share with other people. It is the pace at which the natural swing in heart rate with each breath is largest, in the 2014 review that gave it its name. Resonant breathing, step by step.

4-7-8: the one for bed

In through the nose for 4, hold for 7, out through the mouth for 8, for three or four rounds. The very long exhale leans toward sleep, which makes it the bedtime technique and the wrong one before a meeting. If the holds wake you up or make you tense, use calm breathing in bed instead. 4-7-8 breathing, step by step, and breathing exercises for sleep for the whole wind-down.

Pursed-lip breathing: for when the breath out is hard

Breathe in through the nose for about 2, then out slowly through lips pursed as if you were cooling soup, for about 4. It is the technique respiratory physiotherapists teach to people with lung conditions because the narrow opening keeps the airways open longer on the breath out. For everyone else it is simply another way to make the exhale slow, and it is useful on a stair or a hill. If you have a lung condition, learn it from your own clinician.

Which breathing technique should I use?

  • Stressed, nowhere to be: calm breathing.
  • Stressed and need to function: box breathing.
  • Panic rising, right now: two sighs, then calm breathing.
  • A ten-minute practice, alone or with people: resonant.
  • In bed: 4-7-8, or calm breathing if holds wake you.
  • Breath feels stuck high in the chest: belly breathing first.

The breathing exercises page has the same choices in a table with the steps, and breathing techniques for anxiety goes deeper on the anxious cases. Techniques that use fast breathing or long holds to produce strong sensations are a different thing, best learned in person; breathwork for beginners explains where the line is.

Questions people ask

What is the most effective breathing technique?

For calming down, any pattern where the breath out is longer than the breath in, kept up for two to five minutes; calm breathing at 4 in, 6 out is the simplest. For the first seconds of panic, the physiological sigh is the fastest.

What is the 4-7-8 breathing technique for?

Sleep. The long exhale and the hold lean toward drowsiness, which is why it is the bedtime pattern and a poor choice before anything you need to be alert for.

How many breathing techniques should I learn?

Two is enough: one with no holds for everyday calm, and one quick reset for a bad moment. Add box breathing if you often need to be calm and sharp at the same time.

Can I do breathing techniques lying down?

Yes, and for belly breathing and 4-7-8 it is the easier position. For box or resonant breathing before a task, sit up so you stay alert.
