Sit and breathe normally for a minute first. Then, after a quiet, unforced exhale, pinch your nose and start the timer. Hold only to the first definite urge to breathe — this is not a maximum hold. Release and breathe gently through the nose. If your first breath after is a gasp, you held too long; the number doesn't count.
A set of small, comfortable breath holds — the everyday CO₂-tolerance drill. After a normal exhale, pinch your nose and hold for the count shown, then release and breathe normally through the nose until the next round. The holds should stay easy: never finish one gasping.
Hold length is set from your latest control pause: seconds a hold, six rounds.
If you're pregnant, or manage a heart or respiratory condition, clear breath-hold work with a clinician first. Never do holds in water or while driving.
A low tone starts the exhale, a higher one starts the inhale, a middle one starts a hold. Enough to follow with your eyes closed.

Tide paces slow breathing. Coherent breathing at five to six breaths a minute is the core practice; box and 4-7-8 cover steadying and winding down. All three are open, published physiology — nothing here is proprietary.
The control pause measures how long you stay comfortable after a normal exhale — a rough read on CO₂ tolerance that tends to climb with lighter, slower breathing. Track it over weeks; don't chase a number in a day. The breath-hold set is gentle practice, never a test of will, and the research behind these methods is more modest than their promoters claim.
The Ladder is a ratio practice — inhale, hold, exhale, hold — that grows over weeks. Climb only when the current rung is comfortable, and drop back the moment a hold makes you gasp or the next breath comes ragged. Retention isn't a competition.
If a hold feels bad, skip the hold patterns and stay with Coherent. Don't use breath holds in water, while driving, or standing up if you get lightheaded.
