Ujjayi means the ocean and this pranayama is about mimicking the oceanic sound or the sound of the waves.
Step by Step
Be seated in a comfortable position crossing your legs.
Now start to inhale normally with the mouth.
While doing this, start to constrict your throat as if something is choking it/as you’d fog a mirror when you exhale out the mouth similar to the ocean when you breath.
You can repeat this pranayama breathing exercise for about ten to fifteen times.
Benefits
