Breathing Exercise Timer
A paced circle for box breathing, 4-7-8, and longer-exhale calm.
Slow the breath, steady the system
Set the counts and follow the circle — in, hold, out. Longer exhales lean the body toward calm.
Breath pacing is the one nervous-system control surface you can operate directly. Stop if you feel dizzy, and breathe normally between practice rounds.
- Follow 4-4-6 for five cycles before your next study block.
- Compare how 4-2-4 and 4-4-8 feel — where does your attention go?
Breath pacing is the one nervous-system control surface you operate directly. Longer exhales in particular nudge the body toward its rest state, which is why patterns like 4-4-6 and 4-7-8 show up everywhere from yoga to clinical calm-down protocols.
Set the counts, press start, and follow the circle — in as it grows, hold, out as it shrinks. Stop if you feel dizzy and breathe normally between rounds.
What is box breathing?
Equal counts in-hold-out-hold (classically 4-4-4-4) — this pacer covers the in-hold-out core of it.
How long should I practice?
Even five slow cycles measurably settles most people; a few minutes before study or sleep is plenty.
