Box breathing, also known as square breathing, is a simple technique for controlling your breath. It follows a four-part cycle: inhaling, holding the breath, exhaling, and holding again, all for an equal count.
People in desk jobs often use this exercise to manage stress or regain focus during a busy day. It can be a useful tool before a meeting, on a call, or after completing a difficult task.
What the box breathing works
Box breathing is an exercise for your mind and nervous system. It works by focusing your attention on the rhythm of your breath. This practice helps guide your breathing into a regular, controlled pattern.
How to do it
Starting position: Sit or stand comfortably with your back straight but relaxed. Rest your hands in your lap or on your desk.
- Gently inhale through your nose for a count of four.
- Hold your breath at the top of the inhale for a count of four.
- Slowly exhale through your mouth or nose for a count of four.
- Hold your breath at the end of the exhale for a count of four.
- Repeat the cycle for a few minutes.
What you should feel
As you practice box breathing, you should feel a sense of calm and focus. Your breathing should be gentle and controlled, not forced or rushed. Avoid tensing your shoulders or neck; they should stay relaxed throughout the exercise.
Common mistakes
- Forcing the breath instead of letting it be gentle.
- Tensing your shoulders or neck.
- Rushing the count.
Make it easier or harder
- Easier: Use a shorter count, such as a count of three for each step.
- Easier: Skip the holds and just focus on inhaling and exhaling to an even count.
- Harder: Increase the count to five or six for each part of the breath cycle.
- Harder: Practice for a longer duration, such as five to ten minutes.
Fitting it into a desk day
Box breathing is a very discreet exercise that you can do right at your desk. Because it is quiet and requires no movement, you can use it to find focus before a meeting or to reset after a challenging task. No one around you needs to know you are doing it.

What if I feel dizzy when I do box breathing?
If you feel lightheaded or dizzy, try using a shorter count for each step, such as a count of three. If the feeling does not go away, you should stop the exercise.
