Kapalbhati

Almost every page about Kapalbhati leads with the benefits. This one leads with the dangers, because the dangers are specific, the benefits are modest, and in four decades of teaching the harm I have seen has all come from people who were never told the first part.

Who must not do Kapalbhati. High blood pressure. Heart disease of any kind. Any hernia, including a hiatus hernia. Pregnancy, and the months after a caesarean. Glaucoma or raised eye pressure. Abdominal or chest surgery in the last three to six months. Epilepsy. An active stomach ulcer. Severe asthma or COPD in a flare. The full list with the reasons is below, and it is not a formality: this is the one practice I actively stop students from doing, and I stop somebody in most beginner intakes.

Why those, specifically. Kapalbhati is 90 forced abdominal contractions in five minutes. Each one drives up the pressure inside the abdomen and the chest, which is why it is wrong for a hernia, wrong for a healing surgical wound and wrong for a pregnant abdomen. The same pressure travels up through the chest and the head, which is why traditional teaching, and every teacher I trust, keeps anyone with raised eye pressure away from it. And the rapid breathing blows off carbon dioxide, which narrows blood vessels in the brain, which is where the dizziness comes from and why epilepsy is on the list.

What it actually does for you. It clears the nose and the sinuses, reliably and immediately. It wakes you up. It gives you conscious control of an abdominal wall most adults cannot isolate at all. There is a modest trial literature suggesting effects on lung function and on autonomic balance, mostly small, short and unblinded.

What it does not do. It does not burn belly fat, it does not detoxify anything, and it does not treat diabetes or thyroid disease. Those claims are made constantly on Indian television and in Hindi videos, and there is no trial evidence that supports them at the strength they are asserted. The abdominal movement is not fat loss; it is a muscle contracting. I would rather you practised it for the reasons that are true.

Numbers first, because the internet gives wildly different ones and some of them are irresponsible.

• Week 1 to 2: 3 rounds of 15 strokes, at one stroke a second, with a full minute of ordinary breathing between rounds. About four minutes total.
• Week 3 to 8: 3 rounds of 30 strokes. About five minutes. This is a complete daily practice and most people never need to go beyond it.
• Experienced, healthy, with a teacher: 3 rounds of 50 to 60 strokes. Ten minutes at the outside.
• Speed: 60 strokes a minute, one a second, at every stage. Speed is not the progression.
• Frequency: once a day, in the morning. Not twice, not before bed.

Counts of 300 and 500 strokes circulate widely. I do not teach them and I would not do them myself. The people I have seen with abdominal soreness, a headache lasting the morning or a genuinely frightening bout of dizziness were all doing counts like that, all self taught, and all convinced that more was the point.

Progress by adding strokes to a round, five at a time, once the current count leaves you completely comfortable at the end. If any round ends with you breathing hard, the count is already too high.

Kapalbhati for belly fat is probably the most searched thing about this practice in India, so it deserves a straight answer rather than a polite one.

Five minutes of Kapalbhati burns a trivial number of calories. It is a small muscle group working briefly. Nothing about the mechanism targets fat over the abdomen, and spot reduction of fat from a specific area is not something the body does for any exercise. If a page tells you 500 strokes will flatten your stomach, that page is selling something.

What is fair to say is narrower. Kapalbhati teaches you where your deep abdominal muscles are, and people who can find those muscles hold themselves differently and often look different in the mirror within a few weeks without having lost a gram. It also tends to arrive as part of a morning routine, and it is the routine, the walking, the Surya Namaskar and the changed eating that move weight.

So: practise it because it clears your head and your nose and gives you five minutes of attention first thing. If weight is the goal, the honest answer is that Surya Namaskar done for twenty minutes will do far more, and a doctor or dietitian will do more still.

These two get confused constantly, including by teachers, and the confusion matters because the safety lists are not identical.

In practice, half the people who tell me they do Kapalbhati are doing a slow, sloppy Bhastrika: pulling the inhale in as hard as they push the exhale out. That is why they are dizzy. If you are actively inhaling, you are not doing Kapalbhati. See the Bhastrika page for how that practice is properly counted and where its own limits are.

The order I use in the hall is settled, and Kapalbhati has a fixed place in it.

1. Clear the nose. Blow it, and use a jala neti pot if you use one.
2. Kapalbhati: 3 rounds of 30. Five minutes.
3. One minute sitting still, breathing normally.
4. Anulom Vilom: 12 rounds, six minutes. This is the settling counterweight and it is not optional.
5. Asana, if the day allows it.
6. Savasana at the end, always.

Kapalbhati goes first among the breathing practices because it clears the nasal passages, and everything after it is easier through a clear nose. It goes before asana rather than after because it is a stimulant and you want that energy for the movement, not left over at the end.

If you are over forty and new to this, start without Kapalbhati altogether for the first month and add it once the seated practice is established. The beginners over 40 page explains the order I use for that, and blood pressure is the reason it exists. In the online classes I watch the shoulders during Kapalbhati more closely than anything else, because a lifting shoulder is the visible sign of somebody forcing it.

This is the practice where the published numbers are most reckless, with videos asking beginners for a hundred strokes on day one. This ladder takes a month to reach ninety.

The exhalation is the stroke and the inhalation happens by itself. If you are actively pulling air in, you are doing twice the work and will be dizzy inside twenty strokes.

Kapalbhati is the practice this site is most careful about, and the split is worth reading in full before you start doing a hundred strokes because a video told you to.

• Yoga for weight loss includes it, in small doses, as one part of a practice that gets its results from the standing work rather than from the breathing.
• Yoga for high blood pressure advises against it, because a forceful practice raises pressure while it is being done.
• Yoga for anxiety advises against it, because forceful breathing in an already activated nervous system reliably makes people feel worse, and I have watched that happen in a hall.
• Yoga for PCOS and yoga for diabetes both leave it out in favour of slower practices.

If you want the energising effect without the risk, Anulom Vilom at a brisk pace does more than people expect. Sit for either in Vajrasana, never straight after a meal.
