Box breathing and calm breathing

Box breathing is a 60-second reset for a racing mind and body - and you can do it anywhere.

How we breathe talks directly to the nervous system. Slow, even breathing tells the body "I am safe," calming a racing heart and mind. Box breathing is a simple, portable way to do it.

How to box breathe

Picture drawing the four sides of a square:

  1. Breathe in through your nose for a count of 4
  2. Hold for 4
  3. Breathe out slowly through your mouth for 4
  4. Hold for 4

Repeat for about a minute (4-6 rounds). If holding feels hard, drop the holds and simply make your out-breath longer than your in-breath (e.g. in for 4, out for 6) - the long out-breath is what calms you.

When to use it

  • Before a stressful meeting, exam or difficult conversation
  • When you feel anxiety or anger rising
  • To wind down for sleep

Why it works

Long, slow out-breaths activate the body's "rest and calm" system, lowering heart rate and stress hormones within minutes.

A note

If you feel dizzy, return to normal breathing - that is fine and passes. Practise when calm so it is second nature when you need it.
