In one breath

Anulom Vilom, the alternate nostril breathing, is done in 12 rounds, about 6 minutes, on a 4:4:8 count. Best time: early morning on an empty stomach, ideally before sunrise, or any time at least four hours after a meal. a second short sitting at dusk suits people who cannot manage mornings.. Read the list of who should not do it before your first round.

What Anulom Vilom actually is

Anulom Vilom is alternate nostril breathing: you inhale through one nostril, close it, and breathe out through the other, turn and turn about. The Sanskrit is plain about it. Anuloma means with the grain, in the natural direction; viloma means against the grain. The practice takes the breath one way and then the other, and the name is a description rather than a claim.

At the count taught here it is 12 rounds and about six minutes, on a 4:4:8 count once you have earned the hold, and 4:0:8 until then. One round is two full breaths: in through the left and out through the right, then in through the right and out through the left. Beginners routinely count that as two rounds and end up doing half a practice, so count a round only when you arrive back at the left nostril.

Two things are doing the work. The first is the ratio: an exhale twice the length of the inhale drops the breathing rate towards six breaths a minute, which is where the heart and the baroreflex start behaving differently. The second is the alternation itself, which is what people mean when they talk about balancing the two sides. Physiologically the nostrils do alternate on their own in a nasal cycle of roughly one to three hours, and the practice deliberately overrides that for a few minutes.

What it is not is a strenuous practice. Nothing in Anulom Vilom should make you hot, breathless or determined. If your face is tightening, the count is too long for today. Shorten it and keep the ratio.

Anulom Vilom vs Nadi Shodhana, the difference

This is the most common question I get about either practice, and most answers online say they are simply the same thing. They are close relatives, not twins. Here is the distinction as the hatha texts draw it, and as I teach it.

 Anulom VilomNadi Shodhana
Literal senseWith the grain and against it: alternating the nostrilsPurification of the nadis, the channels
Breath retentionUsually taught without kumbhaka, or with a short 4:4:8 holdRetention is part of the classical practice, often 1:4:2
BandhasNoneJalandhara bandha, and sometimes mula bandha, during the hold
Who it is forAnyone who can sit up, from the first weekTaught after a year or two of steady practice, in person
Where it sitsA daily settling practiceA preparatory practice for meditation and for the deeper pranayamas

Put simply: every Nadi Shodhana is an alternate nostril breath, but not every alternate nostril breath is Nadi Shodhana. Anulom Vilom is the plain alternating breath. Nadi Shodhana is that same alternation performed as a formal practice, with a defined ratio, a long retention and the chin lock holding the pressure in the right place.

Does the difference matter for you? If you are practising six minutes a day at home to sleep better and think more clearly, no. Do Anulom Vilom, leave the retention alone, and you have everything you came for. It matters the moment somebody suggests you hold the breath for sixteen counts, because that is a different practice with a different risk profile, and it belongs with a teacher in the room. The full Nadi Shodhana page sets out that ratio and its conditions.

One more honest note. The research literature does not respect this distinction at all. Trials use the two names interchangeably, and a study titled Nadi Shodhana will often describe a protocol with no retention, which is what I would call Anulom Vilom. When you read a paper, read the method, not the title.

How many rounds, what ratio, and how to build up

Numbers, because that is what people actually want.

  • Week 1 to 4: 9 rounds on a 4:0:8 count. No retention. About four minutes.
  • Month 2: 12 rounds on 4:4:8. About six minutes. This is the practice most people should stay on permanently.
  • Month 6 onwards, if you are well and have a teacher: 12 rounds on 5:5:10, or 15 rounds on 4:4:8. Ten minutes at most.
  • Twice a day: better than one long sitting. Six minutes morning and six minutes evening beats twelve minutes once.

Do not chase the classical 1:4:2 ratio at home. A count of 4:16:8 means holding the breath for sixteen seconds, twenty four times in a sitting, and that is where blood pressure spikes, where people get dizzy, and where the practice stops being safe to self teach. I have taught for four decades and I still teach that ratio only face to face.

Increase the count, not the clock. When 4:4:8 has been comfortable and silent for a month, go to 5:5:10 rather than adding rounds. Length of breath is the thing that develops; number of rounds is just how long you sit.

Time of day, empty stomach, and where it fits

Early morning is best, on an empty stomach, before you have looked at a phone. The traditional window is brahma muhurta, the ninety minutes or so before sunrise, and there is a practical reason behind the poetry: the stomach is empty, the mind has not yet been loaded, and nobody will interrupt you.

The empty stomach rule is not superstition. The diaphragm has to move down into the abdomen to fill the lower lungs, and a full stomach blocks that. Four hours after a main meal, two after a snack. Water is fine.

If mornings are impossible, practise at dusk before dinner. Avoid the hour immediately after eating, and avoid the last thing at night if you find it makes you alert, which about one person in five does. For those people I move Anulom Vilom to the morning and give them Bhramari at night instead.

In a class the order is fixed: movement, then a short rest, then pranayama, then savasana. Ten minutes of Surya Namaskar or the ten minute morning sequence is enough to loosen the ribs before you sit. Sitting down cold and expecting a long, smooth breath is the commonest reason a beginner concludes that pranayama is not for them.

How to sit, and what to do if you cannot

The seat decides the breath. Six minutes is long enough that a bad position will win.

  • Best: Padmasana or ardha padmasana on a folded blanket, knees below hip level.
  • Excellent and much easier: Vajrasana, kneeling, with a cushion between the heels and the sitting bones. This one keeps the spine upright with no effort at all, and it is the only sitting pose that is fine soon after a light meal.
  • Perfectly acceptable: a firm dining chair, feet flat, back not touching the backrest, hips slightly higher than the knees.
  • Not acceptable: a sofa, a bed, or cross legged on the floor with the back rounded and the knees up near the chest. All three collapse the front of the body and shorten the breath you are trying to lengthen.

Knees that hurt in any cross legged position are a knee problem, not a yoga problem. Use the chair without embarrassment. In forty years I have never seen a student get more out of the practice by enduring their knees.

What to expect in the first month

Days 1 to 3. One nostril feels shut. The count feels long. You lose track of which side you are on. All normal. Do 9 rounds and stop.

Week 2. The blocked side starts clearing during the practice itself, usually around round five. Most people notice the exhale getting genuinely easier to stretch before they notice anything else.

Week 3 to 4. The thing students report first is not calm, it is that they catch themselves breathing slowly at other times of day: in a queue, in traffic, before a meeting. That transfer is the real result, and it arrives before any of the measurable ones.

What should not happen. Dizziness, tingling in the hands or around the mouth, a headache, or a racing heart. Every one of those means you are over breathing, holding too long, or straining. Stop, breathe normally for two minutes, and next time shorten the count. If dizziness happens twice, drop retention altogether and tell a teacher. For anxiety in particular, the yoga for anxiety page explains why a shorter, easier count often works better than a longer one.

Rounds and ratio, week by week

Every published source gives a different number, and none of them says where the number came from. This is the ladder I teach, with no retention until the fourth week and none at all if your blood pressure is high.

WeekRoundsRatio or countTimeStop if
Week 16 rounds4 in, 4 out, no holding3 minutesYou run out of air before the count
Week 29 rounds4 in, 4 out4 minutesThe shoulders lift on the inhalation
Week 312 rounds4 in, 6 out5 minutesThe next few breaths are gasped
Week 4 onwards12 rounds4 in, 8 out6 minutesAny strain at all in the count

If you have high blood pressure, are pregnant, or have any heart condition, stay on the no retention rows permanently. Lengthening the exhalation is where the effect is anyway.

The conditions this practice is used for here

Alternate nostril breathing without retention is the safest of the counted practices, and that is why it appears where it does on this site.

  • Yoga for high blood pressure uses it as the main practice, nine rounds, with no breath holding at any point.
  • Yoga for diabetes uses it as the sit down practice after the standing work, because it is something a person will still be doing in six months.
  • Yoga for anxiety uses it once Bhramari has made the exhalation longer, and not before.

Sit upright with the spine supported, in Vajrasana, on a cushion or on a chair. It goes at the end of a practice rather than the beginning, after Savasana or before it, and it is the practice that the bedtime sequence finishes with. If the counting is what puts you off, a class is where that gets sorted out in five minutes.

How to do it, step by step

12 rounds, about 6 minutes is a full practice. Stop early on any round that feels like effort rather than ease: strain in pranayama is not something you push through.

  1. Step 1. Sit in sukhasana, ardha padmasana, padmasana or vajrasana, or on a firm chair with both feet flat on the floor. Sit on the front edge of a folded blanket so the knees fall below the level of the hips. If the lower back rounds, you will be fighting your own posture for six minutes and the breath will never lengthen.

  2. Step 2. Rest the left hand on the left knee, palm up or down, whichever leaves the shoulder soft. Straighten the spine, lengthen the back of the neck, drop the chin a few millimetres and close the eyes.

  3. Step 3. Make nasagra mudra with the right hand: fold the index and middle fingers in towards the palm, or rest them lightly on the forehead between the eyebrows. The right thumb will close the right nostril and the ring finger, helped by the little finger, will close the left.

  4. Step 4. Breathe normally for thirty seconds and simply notice which nostril is more open today. One almost always is. This is not a fault to correct, it is information, and it changes roughly every ninety minutes on its own.

  5. Step 5. Close the right nostril with the thumb. Inhale slowly and silently through the left nostril for a count of four. Fill the belly, then the lower ribs, then the upper chest. No sound at the nose means the pace is right.

  6. Step 6. Close the left nostril with the ring finger so both are shut, and pause for a count of four. This is antar kumbhaka, the internal hold. Leave it out entirely for your first month, and leave it out for good if you have high blood pressure, heart disease, glaucoma or are pregnant.

  7. Step 7. Release the thumb and exhale through the right nostril for a count of eight. Long, thin and unhurried. The exhale is the half of the practice that does the settling, so let it be genuinely twice the inhale rather than nearly so.

  8. Step 8. Inhale through the same right nostril for four, hold for four, then close the right and exhale through the left for eight. That completes one round. Notice the pattern: you always exhale through the nostril you did not just inhale through, and you always start a round on the left.

  9. Step 9. Continue for 12 rounds, which takes about six minutes at this count. Keep the face still, the jaw unclenched and the right elbow low rather than winged out to the side. If the elbow aches, support it with the left hand under the right forearm.

  10. Step 10. Finish at the end of a left nostril exhale. Lower the right hand to the knee, keep the eyes closed and sit for two minutes breathing ordinarily. Do not stand up while the eyes are still adjusting: a long practice can leave you briefly light headed, and that is the moment people fall.

What it is good for

  • The best evidence is for blood pressure. A 2024 systematic review and meta-analysis of alternate nostril breathing pooled six randomised trials covering 525 people and found systolic pressure about 7 mmHg lower and diastolic about 5 mmHg lower. The authors are careful to say the trials were very varied and none were blinded, so treat that as a real but imprecise effect. Source
  • A study of 132 healthy adults aged 25 to 50 measured pressure immediately after slow alternate nostril breathing and found a clear fall in systolic and mean arterial pressure compared with right nostril breathing. The authors call the size of the effect mild to moderate, and note that most measures did not change significantly in the female participants. Source
  • Slow breathing below ten breaths a minute, which is what a 4:4:8 count produces, consistently raises heart rate variability and respiratory sinus arrhythmia, shifts the EEG towards alpha, and is reported as more relaxing and more comfortable. That review covered fifteen studies in healthy people, so it describes the mechanism rather than a treatment. Source
  • For anxiety the honest position is that the evidence is thin. A randomised pilot study put fifteen minutes of alternate nostril breathing against a public speaking stress test and found only a trend towards lower anxiety, not a statistically significant result. Source
  • Effects differ from person to person. A 2025 crossover trial in 45 people found that improvements in mood and alertness depended on which nostril was dominant at the start, which fits what I see in class: two students doing the identical practice report quite different things. Source
  • In forty years of teaching, the reliable result I can vouch for is that students start breathing more slowly at other times of the day without meaning to, usually in the third or fourth week. That transfer out of the practice and into ordinary life is what I actually watch for.
  • It is the practice I give people who cannot sit still. Having something to do with the hand and a count to keep gives a restless mind a job, and students who gave up on meditation twice usually manage six minutes of this on the first attempt.

Who should not do this

  • If you have uncontrolled high blood pressure, practise the breathing without any breath retention at all. Kumbhaka raises intrathoracic pressure and blood pressure during the hold, and a 4:8 inhale to exhale with no hold gives you almost all of the calming effect with none of that.
  • With heart disease, a recent cardiac event, an arrhythmia or a pacemaker, take up alternate nostril breathing only with your cardiologist informed, and never with retention.
  • In pregnancy, keep to the simple alternate nostril breath without holds, sit with the hips raised on a cushion, and stop if you feel light headed. Do not start any new breathing practice in pregnancy without telling the doctor looking after you.
  • With glaucoma, a detached retina or after recent eye surgery, avoid breath retention. Holding the breath raises pressure in the head, and the eye is the part of you least able to tolerate that.
  • During an acute sinus infection, a heavy cold or with a fully blocked nostril, skip the practice. Forcing air through an inflamed passage is painful and pointless. Come back to it when the nose is clear.
  • With a deviated nasal septum or nasal polyps, one side may never open properly. Do not press harder on the finger to compensate. See an ENT surgeon, and in the meantime practise Bhramari instead.
  • If you have epilepsy, do not practise breath retention on your own. Learn the practice in person with your neurologist informed.
  • Never practise on a full stomach. Wait four hours after a main meal and two after a snack, or the diaphragm has nowhere to go and you will feel queasy.

Breathing practices change blood pressure and heart rate for real, not metaphorically. If any of these describe you, say so before you start, and leave breath retention alone until somebody has watched you practise.

What Vaithialingam sees people get wrong

What goes wrong most often in this practice, on the left, and what to do instead, on the right.

  • Pinching the nose hard enough to leave a mark, and squashing both nostrils sideways.

    The fix. The finger rests on the soft flesh at the side of the nostril and closes it with the weight of the hand only. Close one at a time and check in a mirror once: the nose should not be pushed off centre.

  • Adding breath retention in the first week because a video said 4:16:8.

    The fix. Do a month of 4:0:8 first. Retention is the part of pranayama that can actually hurt somebody, and it is the last thing to add, not the first. When you do add it, go to 4:4:8 and stay there for another month.

  • Making the inhale audible, a thin whistling at the nostril.

    The fix. Sound means the airway is too narrow for the speed you are pulling. Slow the inhale until it is silent. Silence, not the count, is the real measure of whether the pace suits you today.

  • Lifting the right elbow up and out, which drags the shoulder towards the ear.

    The fix. Keep the upper arm hanging close to the ribs and bring the hand to the nose rather than the nose to the hand. If it still tires, prop the right elbow in the left palm.

  • Starting a round with the right nostril because it happens to be the open one.

    The fix. Every round begins with an inhale through the left and ends with an exhale through the left. Keeping the order fixed is what makes the practice countable and repeatable. If the left is blocked, lie on your right side for five minutes first and it will usually open.

  • Counting the rounds on the fingers of the left hand and losing track anyway.

    The fix. Count in threes: three rounds, then check the shoulders, then three more. Twelve rounds is four of those small sets, and it is far easier to hold than a running count of twelve.

From Vaithialingam's class

I have taught this to more people than any other breathing practice, because it is the one a complete beginner can do correctly on the first morning. The mistake I have watched for four decades is the same one every time: the hand. People grip the nose as if they are about to jump into a well, the elbow comes up, the shoulder climbs, and within four rounds the neck is doing all the work and the breath has got shorter, not longer. So now I do not talk about nostrils at all in the first lesson. I put the right hand on the face, ask the student to let the arm hang heavy from the shoulder, and we sit like that for a minute before a single round. The second thing I refuse to do is teach retention early. Somebody always arrives having read about a sixteen count hold and wanting to try it, and I say the same sentence I have said for years: come back in a month and we will talk about it. Almost nobody asks again, because by then the plain breath is doing what they wanted.

This is what he sees in class, not a medical claim. Where this page states what a practice does for a condition, the evidence is in the sources cited on the page.

Questions people ask

How long should we do anulom vilom?

Twelve rounds, which takes about six minutes. Start with nine rounds and no breath retention for the first month, then move to twelve rounds on a 4:4:8 count. Two sittings of six minutes, morning and evening, work better than one long session.

What is the difference between anulom vilom and nadi shodhana?

Anulom Vilom is the plain alternate nostril breath, usually with no breath retention and no locks. Nadi Shodhana is the same alternation performed as a formal practice, with a set ratio such as 1:4:2, a long retention, and the chin lock during the hold. Every Nadi Shodhana is an alternate nostril breath, but not every alternate nostril breath is Nadi Shodhana. Research papers use the two names interchangeably, so read the method rather than the title.

Is anulom vilom good for high blood pressure?

Yes, but without any breath retention. Practise a 4:0:8 count, inhale for four and exhale for eight, and never hold the breath in or out. Holding raises pressure inside the chest during the hold, which is the part you do not want. Keep taking what your doctor prescribed and keep your check-ups.

What is the best time to do anulom vilom?

Early morning on an empty stomach is best, ideally before sunrise. Otherwise any time at least four hours after a main meal or two hours after a snack. A short evening sitting before dinner also works. About one person in five finds it makes them alert, and those people should keep it to the morning.

Which nostril do I start with?

Always inhale through the left nostril first, and always finish the practice on a left nostril exhale. Keep the order fixed even if the left side feels more blocked. If the left is genuinely shut, lie on your right side for five minutes before you sit, which usually opens it.

Should I hold my breath during Anulom Vilom?

Not for the first month, and not at all if you have high blood pressure, heart disease, glaucoma, epilepsy or are pregnant. After a month of comfortable practice you can add a four count hold after the inhale. The long classical holds of sixteen counts belong in a room with a teacher, not in a home practice learnt from a video.

Why do I feel dizzy during Anulom Vilom?

Almost always because the count is too long for you today, or because you are holding the breath. Stop, breathe normally for two minutes, and next time shorten the inhale to three counts and drop the retention. If it happens twice, practise without any hold at all and speak to a teacher before going further.

What are the benefits of anulom vilom?

It slows the breath and lengthens the exhalation, which is the mechanism behind most of what people report: feeling settled, sleeping a little better, and a lower resting heart rate during and shortly after the practice. It also gives a person something to do with attention that is not their own thoughts. Claims beyond that, about curing conditions or cleaning organs, I would not repeat.

Who should not do anulom vilom?

Nobody has to leave the practice out entirely, but the retention does. Anyone with high blood pressure, a heart condition, glaucoma, epilepsy, or who is pregnant should practise without holding the breath at any point, which is the version this page teaches anyway. Do not practise with a blocked nose or an active sinus infection, and stop at once if you feel light headed.

What are the side effects of anulom vilom?

Practised gently there are almost none, which is why it is the one I teach first. Done too forcefully or too long, people report light headedness, tingling in the hands or the face, a dry nose, and occasionally a headache. All of those mean the same thing: you are moving more air than you need. Shorten the count, drop any retention, and stop for the day.

Can anulom vilom cure all diseases?

No, and the claim does real harm. It is a calming breathing practice with a modest, believable effect on how settled a person feels, and there is no good evidence it cures anything. If somebody tells you to replace a prescribed medicine with it, that is the point at which to leave the room. Practise it alongside your treatment and tell your doctor you are doing so.

Can we do anulom vilom during periods?

Yes. There is nothing forceful in it, no retention as it is taught here, and no pressure on the abdomen, so it is one of the practices that stays in on the days when the stronger ones come out. Sit however is comfortable, including on a chair, and shorten the session if you would rather. The forceful practices are the ones to leave alone.

Does anulom vilom reduce belly fat?

No. Breathing practices do not create an energy deficit, and nothing reduces fat in one place. The videos that claim otherwise are usually selling a course. What it does do, honestly, is make people calmer and more likely to keep up a practice at all, and it is the practice you keep that eventually changes something.

Can anulom vilom be done after eating?

Wait two hours after a full meal and about an hour after something light. A full stomach makes slow deep breathing uncomfortable rather than dangerous, and most people simply cannot sit upright and breathe well straight after eating. Early morning on an empty stomach is the traditional time and remains the easiest one.
