Ocean Breath

The rustle of air passing through your throat. A silent inhale, an exhale like a seashell. Getting the sound right is the technique itself.

5 min read

Breathe in quietly through the nose for four seconds. Narrow your throat very slightly and breathe out through the nose over six seconds — letting out a soft rustle like a seashell.

Its Sanskrit name is Ujjayi. It is the breath you hear about most in yoga classes.

Where the sound comes from

Not from the vocal cords. Narrowing the air passage at the back of the throat very slightly makes the air rub as it passes, and that rustle is the result.

The easiest way to find it: open your mouth and breathe out onto your palm with a "haaa", as if fogging a window. What is happening in your throat at that moment is the right thing. Then close your mouth without interrupting the breath — the sound softens but continues.

The tutorial in the app follows exactly this order.

What the ocean breath is good for

That slight narrowing slows the exhale by itself. You get a long exhale without forcing it.

Its second job, and perhaps its real one, is about attention: a continuous sound leaves a marker you can return to when your mind drifts. That is also why it is so widespread in yoga classes — it makes following the breath easier while moving.

No sound on the inhale

The classical texts ask for sound on both the inhale and the exhale. In the app, sound is asked for only on the exhale.

The reason is measurement: adding sound to the inhale was found to add nothing and to raise heart rate. Leaving the inhale free makes the technique both easier and better working.

How to do the ocean breath

Sit upright. Breathe in quietly through the nose for four seconds — do nothing on the inhale.

Narrow your throat very slightly and breathe out through the nose over six seconds. The sound should be no louder than a whisper: someone next to you hears it, someone two metres away doesn't.

Common mistakes in the ocean breath

Squeezing the throat. The most widespread mistake. Narrowing doesn't mean using muscle — the air should rub by itself. If your throat hurts, you are pushing too hard; let it go.

Humming. This technique isn't "mmm", that is the Humming Bee Breath. The sound here is the rustle of air.

Trying to make a sound on the inhale too. The inhale is free.

How the app measures the ocean breath

Because the exhale is audible, this is one of the easier techniques to measure. The thresholds are set accordingly.

What is looked at most is the smoothness of the exhale: the rustle should hold an even volume from start to finish. If the sound cuts out or wavers, there is tension in the throat or the breath is running short.

The rustle gets its own line in the report, named Ocean sound. An ordinary breath let out loudly doesn't count as ocean sound. Most of the score comes from this line, and even when there is no rustle, rhythm and exhales earn their own share.

Who should take care with the ocean breath

If your throat is sore or irritated, don't do this technique. Forcing to produce a sound gains you nothing — a forced Ocean Breath isn't Ocean Breath.
