What is box breathing?
Box breathing splits each breath into four equal parts: in, hold, out, hold. The even count gives your mind something simple to track, which is why it is a favourite before presentations, exams and hard conversations. It was popularised by former US Navy SEAL Mark Divine.
How to do it
- 1Sit upright and let your shoulders drop.
- 2Breathe in through your nose for a count of 4.
- 3Hold the breath gently for 4.
- 4Breathe out slowly for 4.
- 5Hold with empty lungs for 4, then repeat.
Why it works
Slowing your breathing to around four breaths a minute and pacing it evenly tends to shift you towards a calmer, more parasympathetic state. Reviews of slow-breathing research link it with lower arousal and better emotional control, though studies vary in method and size.
Tips
- If 4 counts feels long, start at 3 and build up.
- Keep the holds relaxed. There should be no strain in your throat or chest.
- Two to five minutes is enough to feel a shift.
