Box Breathing
Steady 4·4·4·4 counts — the trick pilots and soldiers use to stay calm when it matters. Even-sided breathing gives the nervous system a metronome: nothing speeds up, nothing slows down, and you settle into the middle of it.
In the app
Two minutes around a square. The pacer traces the four sides so the count is something you watch, not something you keep:
- Breathe in — four counts, one side of the square
- Hold — four counts
- Breathe out — four counts
- Hold — four counts, and the square begins again
When to reach for it
- Before something that needs steady hands and a level head
- When your thoughts are spinning faster than the situation deserves
- As a daily anchor — same square, every time, which is rather the point

Box breathing is one of the four pauses that run on this website: the free box-breathing pacer.
The honest part
Box breathing is widely taught in military and emergency training, and its even counts make physiological sense — but direct research on "box" patterns specifically is thin compared with slow breathing generally. The pacer helps most by keeping the counts honest without counting.
Background: the technique is popularised by the US Navy SEALs' "four-square" drill; for the underlying mechanism see Zaccaro et al., Frontiers in Human Neuroscience, 2018. doi:10.3389/fnhum.2018.00353
