Ujjayi Breathing: The Classical Technique and Its Modern Use in Flow Classes
Written and reviewed by The Kriya Yogi · Updated 21 September 2026
Ujjayi — often called "ocean breath" or "victorious breath" in modern studios — is probably the pranayama technique most people encounter without realising it's a named classical practice, because it has become the default audible breath of vinyasa and power yoga classes. What's taught in a flow class and what the *Hatha Yoga Pradipika* describes overlap, but are not quite the same use of the technique, and it's worth knowing the difference.
The short answers
- Ujjayi means "victorious" or "triumphant"; it is listed among the eight kumbhakas in the Hatha Yoga Pradipika, chapter 2.
- The sound comes from a slight, partial narrowing of the glottis (the space between the vocal cords), not from the nose or the back of the mouth as many verbal cues suggest.
- Classically it is described alongside retention practice; in modern flow classes it is usually taught as a continuous audible breath without any holding, sustained throughout a moving sequence.
- Done well it should sound like distant ocean surf and feel entirely comfortable in the throat; a raspy, effortful or sore throat means it's being forced.
- It is one of the gentler named techniques and has a shorter contraindication list than the forceful techniques, but a tight or held ujjayi can raise blood pressure and should be avoided by people managing uncontrolled hypertension.
- Evidence specific to ujjayi is limited; most relevant research covers slow, controlled breathing generally, which ujjayi is one way of doing.
Classical description
The Hatha Yoga Pradipika describes Ujjayi as a technique in which the mouth is closed and breath is drawn in through both nostrils in a way that produces a sound from the throat, felt from the throat down to the chest, and it appears in the text's list of eight kumbhakas alongside a description of holding the breath and applying jalandhara bandha (the chin lock). In that setting, ujjayi is one specific retention-oriented technique among several, practised in a seated, still context — not a breath pattern meant to run continuously through a physically demanding sequence.
What creates the sound
The audible quality of ujjayi comes from a gentle, partial narrowing at the glottis — the opening between the vocal folds — similar to (but much softer than) the shape your throat makes when you fog a mirror with your breath, or when you whisper the sound "haaa" with your mouth closed. Air moving through this narrowed passage on both the inhale and the exhale creates a soft, continuous sound, often compared to ocean surf or to Darth Vader's breathing in popular teaching shorthand. It is not produced by constricting the nostrils, tensing the jaw, or forcing air loudly through the nose, though those are common substitutes when the throat shape hasn't quite been found yet.
How to practise it
- Sit or stand comfortably, mouth closed, breathing through the nose.
- Exhale with your mouth open, making a soft "haaa" sound, as if fogging a mirror — feel where in your throat that sound is made.
- Close your mouth and try to keep making a quieter version of that same throat shape while breathing through your nose, both on the inhale and the exhale.
- The result should be a soft, even, whispery sound audible mainly to you — not loud enough to fill a room, and not effortful in the throat.
- Practise for a few minutes seated before trying to sustain it during movement.
Classical use versus modern vinyasa use
In the hatha texts, ujjayi is presented as a discrete seated technique, tied to retention and to jalandhara bandha, and framed within the traditional aim of directing prana. In contemporary vinyasa and power yoga, ujjayi has been repurposed as a continuous audible breath maintained throughout an entire moving practice, used as a pacing tool, a focus anchor, and a way for a teacher to gauge whether a room of students is breathing steadily. This is a genuinely useful teaching adaptation — matching breath to movement helps many people move more steadily and stay present — but it is a twentieth-century application layered onto the classical technique, not a direct continuation of what the Pradipika describes. Being honest about that difference doesn't make the modern use less valid; it just means "ujjayi throughout your practice" and "ujjayi as described in chapter two of the Pradipika" are related but distinct things.
When it becomes strain
Ujjayi should not hurt or tire your throat. Signs it has tipped into strain:
- A raspy, hoarse or sore throat during or after practice.
- Tension visibly building in the jaw, neck or shoulders to produce the sound.
- Needing to breathe unusually loudly to "prove" you're doing it, rather than a soft, private sound.
- Holding the breath tightly at the top of the inhale in a moving sequence when the class hasn't cued a retention.
- A feeling of breathlessness or of chasing the breath to keep up with movement, rather than the breath and movement staying easily matched.
If any of this is happening, drop the sound and go back to quiet nasal breathing; movement practice does not require an audible breath to be effective.

In practice
Find the sound with your mouth open first
Exhale audibly as if fogging a mirror; notice the throat shape that creates the sound.
Close the mouth, keep the shape
Maintain a softer version of that same throat narrowing while breathing through the nose.
Aim for soft and even, not loud
The sound should be audible mainly to you, consistent between inhale and exhale, and never strained.
Practise seated before moving
Get the sound comfortable while still, for several minutes, before trying to sustain it through a sequence.
Check the jaw and throat regularly
If tension builds in the jaw, neck or throat, soften the sound or drop it entirely for a few breaths.
Keep retention separate
The classical technique pairs ujjayi with a held breath and jalandhara bandha; add that only with a teacher, not as a habit during flow classes.
Cautions worth reading
- Pranayama changes your breathing pattern, blood gases and blood pressure, sometimes quickly. Stop if you feel dizzy, breathless, light-headed, panicky or unwell, and speak to a doctor before practising any breath-holding or forceful technique if you are pregnant, have high blood pressure, glaucoma or another eye condition, epilepsy, heart disease, a hernia, a panic or anxiety disorder, or have had recent surgery. Retention (kumbhaka) practices, in particular, belong with a qualified teacher.
- A tight, forced ujjayi can raise blood pressure and effort; ease off or stop if you manage uncontrolled hypertension and the practice feels effortful rather than calming.
- Stop if it produces throat pain, hoarseness or a persistent sore throat — this means the technique is being forced, not performed correctly.
- If it triggers breathlessness or panic during a moving practice, return to quiet unforced nasal breathing.
- Avoid combining a long breath-hold with ujjayi unless a teacher has specifically guided you through that combination.
Where the evidence stands
There is little research specific to ujjayi as distinct from slow controlled breathing generally. Studies on slow-paced breathing report modest short-term reductions in heart rate and blood pressure and improvements in self-reported calm, and ujjayi is a plausible way of achieving a slow, even breath rate during movement, but no strong evidence isolates a unique benefit from the throat sound itself as opposed to the breathing pace it tends to produce.
