Anuloma Viloma Timer
How long before anulom vilom does anything? A small 2026 study in Lucknow checked at four weeks.
It is the question that sits under almost every other question about this practice. People do not usually give up on alternate nostril breathing because they find it hard. They give up because three or four days in, nothing obvious has happened, and the morning has other demands. “Kitne din mein asar karta hai” is one of the phrases people type most often next to the practice’s name, for exactly that reason.
What the study did
The paper is “Effect of anuloma viloma pranayama on cardiorespiratory parameters in apparently healthy young adults”, by Verma, Narayan and Singh of the Department of Physiology at King George’s Medical University, Lucknow. It was published on 29 September 2026 in the International Journal of Research in Medical Sciences (volume 14, issue 10, pages 4511 to 4516).
What stands out first is the title. A great deal of breathing research tests “slow breathing”, “paced breathing” or “alternate nostril breathing” in some loosely described form. This one names anuloma viloma and tests it as such.
The participants were 52 healthy adults aged 18 to 26, all with a normal body mass index. One group practised anuloma viloma for 10 minutes a day for 4 weeks. The comparison group did no breathing practice.
After four weeks the practice group had a significantly lower pulse rate, lower systolic blood pressure and lower diastolic blood pressure than the comparison group. They also had a higher peak expiratory flow rate, which is a simple measure of how forcefully you can breathe out.
What it cannot tell you
This is where honesty matters more than enthusiasm.
The published abstract gives the direction of each result but no values, effect sizes or p-values. It also describes the design in terms that mix “groups” and “phases”, so from the abstract alone it is not clear how people were allocated, or whether this was a randomised trial. Until the full numbers are read, the fair summary is direction only: the practice group ended up lower on pulse and blood pressure and higher on expiratory flow.
The participants were young and healthy, with blood pressure already in the normal range. That tells you nothing about what the practice does for someone with hypertension, and it is not a reason to change any medication. Anyone with a blood pressure or heart condition should treat this practice as something to discuss with a doctor, not a replacement for care.
It is also one small study. A larger body of work exists: a systematic review of 44 randomised trials of alternate nostril breathing, which we wrote about on 8 October, found many small positive studies of mixed quality. The Lucknow paper adds one more data point, in a population that is easy to recruit and hard to generalise from.
Why the answer is still useful
Even with those limits, the study answers the “how long” question in a practical way. It did not test a heroic dose. Ten minutes a day is a morning cup of tea. Four weeks is about one cycle of a new habit. That is the scale at which a group of young adults, doing nothing more elaborate than the classic alternate-nostril pattern, showed measurable change on simple instruments.
It also fits what the practice itself has always asked for. The traditional instruction is not to breathe heroically for a weekend, but to sit at the same time each day and let the count lengthen slowly. A four-week horizon is a sensible way to think about it: long enough to judge, short enough to commit to.
If you want to try that horizon for yourself, here is a plain way to do it.
- Pick one time of day and keep it. Before breakfast is the traditional choice, because pranayama is practised on an empty stomach.
- Sit upright. A chair is fine. What matters is a straight, relaxed spine.
- Start with a count you can hold easily. Four counts in, eight counts out, alternating nostrils, with no breath hold at first.
- Do ten minutes. If ten is too much, start with five and add a minute every few days.
- Stop if you feel dizzy or short of breath. Light-headedness usually means the breath is too forceful. Soften it, and rest.
- Judge it at four weeks, not four days. Note how you feel, and if you like numbers, keep a simple record of your resting pulse at the same time each morning.
Night eight
Tonight is the eighth night of Navratri, and for many people the festival has been a gentle structure for a nightly sitting. The Lucknow study is a reminder that the structure is the point. A practice that lasts four weeks is worth more than one perfect evening, and the festival ending on Tuesday does not have to mean the practice does.
