Box breathing is probably the most widely taught breathing technique in the world: in for four, hold for four, out for four, hold for four. Military, police, and emergency-services training use it under the name “tactical breathing,” because it’s easy to remember even when your hands are shaking. It’s good for sustained composure when you have a few spare minutes and a challenging task waiting just ahead, and I use it myself.
Try it now
Four to six rounds. Holds are gentle, throat open. If they make you air-hungry, switch to the no-hold version.
Sitting down, eyes open is fine. Not while driving. If you feel lightheaded, stop and breathe normally.
How to do it
- Inhale through the nose for a count of four.
- Hold for four, gently, with the throat open the whole time and no bearing down against it.
- Exhale for four.
- Hold empty for four.
- Repeat four to six times before moving on.
- If the holds make you air-hungry or panicky, skip them and breathe four in, six out instead.
When to reach for it
- On the walk from the bus stop or in the lobby restroom, before a shift, a meeting, or a hard conversation
- The wait before an exam, an interview, an audition, or a pitch
- A long meeting, a waiting room, or a departure gate, run silently
- While the other person talks, in a conversation you’ve been avoiding
Who should skip it or change it
If you have panic disorder or a strong history of panic attacks, or the holds make you feel air-hungry or panicky, skip both holds and use four in, six out; you lose nothing by the swap, and the same applies if you’re pregnant or have a heart condition until your doctor has weighed in on the holds. Keep the corners out of your bedtime routine, and never do the holds in or near water. Never while driving or operating machinery, this one included.
Common mistakes
What you might notice
The counting gives it a steadying, almost metronomic quality, and for many people the counting does nearly as much work as the breathing. If a hold makes you air-hungry or panicky, that happens reliably for some people, especially with a panic history, and it’s no character flaw.
What it’s good for is sustained composure when you have a few spare minutes and a challenging task waiting just ahead of you. The counting itself gives it a steadying, almost metronomic quality, and for many of the people I’ve taught, the counting does nearly as much work as the breathing.

What the research says
Widely taught in military and emergency-services training; it performed comparably to cyclic sighing in the Stanford trial but has been studied far less as a named protocol. If holds make you air-hungry or panicky, drop them and use four in, six out.

Questions people ask
How long should I do box breathing?
Four to six rounds of in for four, hold for four, out for four, hold for four, then move on. That fits the walk in before a meeting or the wait before a hard task.
Can I do box breathing if I have panic attacks?
Skip both holds. Breathe four in and six out, keeping the box’s four-count inhale so it still feels familiar. You lose nothing by the swap.
Does box breathing have research behind it?
Less than its reputation suggests. It performed comparably to cyclic sighing in the 2023 Stanford trial, but it has been studied far less as a named protocol. It’s widely used, and I use it myself.

Two rules, no exceptions
Never practice any technique on this site while you are driving, operating machinery, or doing anything that needs your full attention. The slow ones can make you drowsy, faster than you’d expect. And never practice a breath-hold, bellows breath, or any vigorous breathing in or near water. Read Before you begin for the doctor’s list and the rest.
