Surya Bhedana

Surya Bhedana is nine rounds, about three minutes, at four counts in through the right nostril and six counts out through the left, in the morning on an empty stomach, with no breath retention for the first three months. Build to twenty seven rounds, about nine minutes, over two months. That is the dose.

The name means piercing the sun, and surya is the right nostril in the classical scheme, associated with pingala nadi and with heat and activity. What makes the practice distinct is one thing only: the inhale is always through the right nostril and the exhale is always through the left. It never alternates. That single rule is what separates it from Anulom Vilom and from Nadi Shodhana, and it is the rule most self taught students break without noticing.

It is a stimulating practice, and unusually for a traditional claim, that one has been measured. Right nostril breathing raises oxygen consumption and systolic pressure while it is being done. That is why it goes in the morning, and why the list of people who should leave it alone is longer than for its mirror twin, Chandra Bhedana.

Nine rounds to start. A round at 4:6 with the hand moving takes around eighteen seconds, so nine rounds is a little under three minutes.

• Week 1 to 2: 9 rounds at 4:6. Three minutes.
• Week 3 to 6: 15 rounds at 4:6. Five minutes.
• Week 7 onwards: 27 rounds at 4:6. Nine minutes. This is the traditional count and my ceiling.
• Frequency: once a day, in the morning, on an empty stomach. Not twice, and never in the evening.
• Retention: none for three months, and none at all if you have high blood pressure, heart disease, glaucoma or a seizure history.

Twenty seven is not a mystical number so much as a countable one: three sets of nine, which is easy to hold in your head with your eyes closed. If you want a longer practice, put Nadi Shodhana after it rather than adding rounds here, because past twenty seven the only thing that reliably grows is the ache in the shoulder holding the hand up.

Competitor numbers for this practice range from three rounds to a hundred and eight and nobody says why. Mine is a two month ladder to twenty seven, and the last column is the part that matters.

The ratio is worth defending. Four in and six out means the exhale is genuinely longer, and the longer exhale is the brake on a practice whose whole tendency is to accelerate you. When somebody tells me Surya Bhedana makes them feel wired rather than alert, nine times out of ten their exhale has quietly shortened to four counts.

Three practices, one hand position, and a great deal of confusion.

The 2024 crossover trial that put all of this to the test found both unilateral practices raised low frequency heart rate variability and slowed the breath, and did not find the clean stimulate-versus-calm split the tradition describes. So use the traditional rule of thumb to decide when to practise, because it is a good practical rule, and do not tell anybody the science has confirmed it. If you only ever learn one of the three, learn Anulom Vilom, which suits almost everybody.

The classical description of Surya Bhedana is not the practice on this page. It has a long retention after the inhale, held with jalandhara bandha, the chin drawn to the chest, and the count grows over years. It is a real practice and I am not dismissing it.

I leave it out of a beginner's page for one reason: the retention changes who may do this. A held breath after a full inhale raises pressure inside the chest and the head, and combined with a chin lock it is inappropriate for anybody with high blood pressure, heart disease, glaucoma or raised eye pressure, a seizure history, or a pregnancy. Breath holding also produces measurable changes in cerebral blood flow, which is the mechanism behind both the effects people seek and the dizziness people report.

So: three months of Surya Bhedana without retention, taught and watched by somebody, before a hold of even two counts. If you want to understand what retention actually does and where the real limits are, that is the whole subject of the kumbhaka page, and it is the one page in this family I would ask you to read before you experiment.

Its place is fixed: after the nose is clear, before the slow work, and never last.

1. Clear the nose. Blow it. If the right nostril will not pass air, stop here and do something else today.
2. Surya Bhedana: 9 rounds, three minutes.
3. One minute of ordinary breathing through both nostrils.
4. Anulom Vilom: 6 to 12 rounds. This is the counterweight and it is not optional.
5. Asana, if the day allows it. Three or four rounds of Surya Namaskar suits this order well.
6. Savasana at the end.

If you are over forty and starting from nothing, leave this practice out for the first month and establish the seat and the slow breathing first. The order in the beginners over 40 page exists because blood pressure is so often the unknown, and a stimulating practice is the wrong place to begin. In the online classes the thing I watch on this practice is the exhale, because a shortened exhale turns it from alert into agitated.

This is a practice with a narrow indication and a wide set of exclusions, and the split across this site reflects that.

• Yoga for high blood pressure advises against it, because right nostril breathing has been measured raising systolic pressure while it is being done.
• Yoga for anxiety advises against it, and sends you to Chandra Bhedana instead. Activating an already activated system is the single commonest way people make anxiety worse with yoga.
• Yoga for thyroid conditions mentions it only to say that the metabolic claims made for heating practices have no trial support at the strength they are asserted.
• The eight limbs guide puts pranayama in its place in the wider scheme, which is a useful corrective if a single breathing practice starts to feel like the whole of yoga.

Sit for it in Padmasana if the hips allow, or Vajrasana, or a chair. If you want the hand position and the finger pressure checked once by somebody watching, that is what an introductory class is for.
