Box breathing is a structured breathing exercise with four equal phases: inhale, hold, exhale and hold again. The most common version uses four seconds for each phase, which is why it is often called the 4-4-4-4 method.
How to practice box breathing
- Inhale gently through your nose for 4 seconds.
- Hold your breath for 4 seconds without straining.
- Exhale slowly for 4 seconds.
- Hold again for 4 seconds, then repeat for 2 to 5 minutes.
When box breathing works best
Use it before a call, after context switching, before public speaking or whenever you want a simple rhythm to steady attention. The square structure makes it easy to follow even when your mind is busy.
Make it easier
If four-second holds feel uncomfortable, start with 3-3-3-3 or remove the holds. A breathing exercise should feel steady, not forced.
