Box breathing
Box breathing — also called square breathing — gives all four parts of the breath the same length: inhale 4, hold 4, exhale 4, hold 4. The even, predictable rhythm is what makes it so good for focus and composure, which is why it's a staple for everyone from Navy SEALs to people steadying their nerves before a big moment. The equal hold after the exhale is the part most people skip — and the part that makes it work.

Also known as square breathing, four-square breathing.
How to do it
- 1Sit upright with both feet on the floor.
- 2Breathe in through your nose for a count of 4.
- 3Hold your breath, lungs full, for a count of 4.
- 4Breathe out through your mouth for a count of 4.
- 5Hold your breath, lungs empty, for a count of 4. That's one round.
- 6Repeat. Scale the count to 3 if 4 feels long, or up to 5–6 as it gets easy.
What it's good for
- Sharpens focus and steadies you before high-pressure moments.
- The symmetric rhythm is easy to remember and pace.
- Trains comfort with gentle breath-holds.
The evidence. Slow, paced breathing around 6 breaths per minute (which box breathing approximates) is well supported for improving focus and lowering stress.
Safety
- Ease off the holds if you feel lightheaded; never practise breath-holds in or near water.
Frequently asked questions
What is box breathing good for?
- Calm, controlled focus. The even four-count rhythm is easy to hold onto when you're stressed, which is why it's used before high-pressure tasks — interviews, public speaking, competition — and to settle down generally.
How long should I do box breathing?
- Even one to two minutes helps reset your focus. Five minutes is a solid session. Start with a 4-second count and lengthen it only when that feels comfortable.
Is box breathing safe?
- For most people, yes. It involves short breath-holds, so ease off if you feel dizzy, and never do breath-holds in water or while driving.
