Why this practice

The throat constriction slows the breath and gives the mind a steady sound to ride, deepening focus while warming and grounding the body.

Ujjayi (pronounced oo-JAH-ee) is a yoga technique where a slight narrowing of the throat creates a soft ocean-wave sound as you breathe. The audible rhythm gives your mind something to follow and generates gentle inner warmth. Used in most physical yoga practices to maintain focus and steady pace.

The science behind it
Ujjayi’s gentle throat narrowing increases airway resistance and slows the flow of air. Slower, paced breathing tends to lengthen exhalations and engage the diaphragm more fully, which supports parasympathetic (rest-and-digest) activation through vagal afferent pathways. Increased vagal tone often shows up as higher heart-rate variability and a calmer autonomic profile; the audible, steady sound of the breath in Ujjayi can also help regularize the rhythm of breathing so the body avoids rapid, shallow patterns that push CO2 too low.

On the psychological side, the audible “ocean” sound becomes an interoceptive anchor—bringing attention to bodily signals (breath, throat vibration, chest/abdomen movement) and reducing cognitive reactivity. That improved interoception supports sustained attention and reduces rumination. Practically, aim for comfortable, unforced five-second inhalations and exhalations; very large or fast breaths can lower CO2 and cause lightheadedness, whereas the moderate slowing and mild resistance of Ujjayi tends to stabilize CO2 and produce a warming, grounding sensation.

A whispered ocean sound on both the in and out breath.

Five in, five out, through a softly narrowed throat.

How to practice

  1. Sit tall and comfortable.
  2. Breathe through the nose, slightly narrowing the back of the throat.
  3. Let the breath make a soft ocean whisper, like fogging a mirror with the mouth closed.
  4. Inhale for 5, exhale for 5, keeping the sound smooth and even.
  5. Let the sound carry your attention inward.
