Classical pranayama

Visama Vritti

Extended exhale.

Say it VISH-uh-muh VRIT-tee विषम वृत्ति

  • Classical pranayama
  • Seated or lying
  • No breath holds
  • 5 min to start
Rhythm in seconds

In 4 · Out 6

5 min · 30 rounds · 5:00 · about 6 breaths a minute

Take care: Keep breaths soft. If the next inhale feels rushed, shorten the exhale.

A breath where the exhale is longer than the inhale. Viram starts with the gentlest form: in for 4, out for 6, with no holds.

How to practise Visama Vritti

  1. Sit upright or lie down, and let your jaw and shoulders soften.
  2. Breathe in through your nose for 4.
  3. Breathe out through your nose for 6, slow and smooth, without pushing the air out.
  4. Keep the breaths soft rather than big.
  5. If you find yourself gasping for the next breath, shorten the exhale in Adjust rhythm.

Each round, step by step

StepSecondsWhat to do
Inhale4In through the nose, soft and easy.
Hold after inhaleOffPause at the top, throat soft.
Exhale6Out through the nose, slow and unhurried.
RestOffPause after an easy exhale.

Take care

Keep breaths soft. If the next inhale feels rushed, shorten the exhale.

  • Keep the breaths soft. Big breaths can make you lightheaded.
  • If the next inhale feels rushed, shorten the exhale.
  • Stop and breathe normally if you feel dizzy or short of breath.
  • The classical form adds long holds. Learn it from a teacher, not from an app.
  • Breathe gently. If you feel dizzy or uncomfortable, stop and return to your normal breath.

Traditionally

Visama vritti means “uneven movement”: steps of different lengths. B.K.S. Iyengar taught it with long holds in ratios such as 1:4:2, and only under a teacher’s eye; the Gheranda Samhita counts a similar ratio. Viram keeps just the lengthened exhale, a gentle, hold-free form closer to modern teaching.

What the research says

Studies often observe higher heart rate variability while people breathe slowly, around six breaths a minute as here. Two small studies of a 4 · 6 pattern, one of 10 men and one of 47 adults, reported calmer readings and less anxiety, but neither had a comparison group. Whether a longer exhale adds anything beyond slowing down is mixed: some studies say yes, and a 2024 study comparing a 1 : 2 ratio with even breaths at the same pace found no difference in heart rate variability. It is not a treatment.
