Yoga for periods

Yoga for periods is safe, and there is no good evidence that any posture harms a menstruating body. The evidence that yoga helps with period pain is real but modest, and it is not the strongest exercise for that job. Those two sentences are the honest answer to the question this page exists for, and the rest of the page is the detail.

On pain, a 2019 meta-analysis in Complementary Therapies in Clinical Practice pooled four randomised trials and 230 women with primary dysmenorrhoea and found a large effect on menstrual pain, a standardised mean difference of about 2.09. That sounds decisive until you notice that four small trials of an unblindable intervention is a thin base, and that effects of that size in small studies usually shrink as bigger ones arrive.

They have started arriving, and the useful comparison is a 2024 network meta-analysis in Sports Medicine Open covering 29 randomised trials and 1,808 women with primary dysmenorrhoea. Every form of exercise reduced pain at eight weeks. Yoga reduced it by 2.75 points, and relaxation exercise did better, at 3.87, and had the lowest dropout rate of any intervention studied. Relaxation was also the most effective at four weeks. So the honest ranking is that yoga works, and lying still and breathing well works slightly better, which is a finding that ought to change what a class gives you on day one rather than being buried.

Nothing here is a treatment for a condition. Yoga may support you through a painful period alongside proper medical care, and period pain severe enough to stop you working, pain that has recently got worse, or bleeding you would call heavy is a doctor's question first. The NHS page on period pain is a sensible starting point for what else is available.

Almost every Indian yoga page on this subject tells you not to invert during your period and gives no reason beyond tradition. It is worth separating three different things that get bundled together.

First, the taboo itself. The usual explanation is that going upside down reverses or obstructs the downward flow of blood. That explanation is not how menstruation works. Menstrual outflow is produced by the muscular wall of the uterus contracting, and during menstruation those contractions run in one direction, from the top of the uterus towards the cervix, to expel the shed lining. A 2023 review in Molecular Human Reproduction describes it exactly that way. It is peristalsis, like a swallow, not drainage, like a bucket. Gravity is not the mechanism, which is also why people menstruate normally lying down all night, and why astronauts menstruate normally in orbit. There is no trial showing that inversions cause retrograde flow, endometriosis, clotting or a stopped period, and no plausible physiology proposed for it.

Second, what the careful traditions actually teach, which is more interesting than the slogan. The Iyengar tradition is the most systematic on this question, and it does tell students to leave out headstand and shoulderstand while bleeding. But it does not tell them to lie down and do nothing. It prescribes supported reclining poses, propped chest openers and supported bridge work during the period, and then brings the inversions back once bleeding has ended, on the reasoning that they help settle an irregular cycle. So even the tradition that holds the taboo most firmly treats the days after the period as the time for inversions rather than treating inversions as forbidden. Whatever you make of the reasoning, that is a coherent practice rather than a prohibition.

Third, what genuinely does not suit day one or two, in my experience of teaching women through it for four decades. This has nothing to do with flow direction and everything to do with a cramping abdomen.

• Naukasana and every strong abdominal contraction. Sit ups, boat pose, leg lifts held, and the pumping breath kapalbhati. A uterus that is already contracting hard does not want the abdominal wall gripping on top of it. This is the one my students report most reliably as making cramps worse within minutes.
• Dhanurasana and deep prone backbends. Lying face down on a tender abdomen and then arching hard is uncomfortable for its own obvious reasons on the first two days. Gentler extension is fine.
• Halasana, plough. This one is on the list for the reason it is on every other page of this site: loaded spinal flexion with body weight through the neck. The period is irrelevant to why.
• Sirsasana and sarvangasana. I do not teach these to beginners at any point in the month, so nothing changes on day one. If you are an experienced practitioner who normally does them, the honest answer is that there is no evidence they harm you while bleeding, and that plenty of experienced women leave them out anyway because they simply do not feel like being upside down. Both of those are reasonable. Neither needs a physiological story attached.
• Anything that has to be held while you are counting the minutes. Not a pose, a principle. Day one is the day to reduce the number of postures rather than the depth of them.

So: no, you do not have to stop practising, and no, the flow will not reverse. And yes, strong abdominal work on a cramping day is a bad idea, which is a much smaller and much better founded piece of advice than the one usually given.

The whole page in one table. On day one pick two from the practise column, not eight. Note that the avoid column separates poses that are a genuinely poor idea from ones that are on the list only by tradition, because those are not the same thing and no other page will tell you which is which.

Two practices, ten minutes, on the worst day. That is a complete practice, not a reduced one.

The shape of a period practice is the reverse of a normal one. Fewer postures, held far longer, all of them supported, and the breathing given more time than the asana.

• Supported baddha konasana for ten minutes, with a cushion under each thigh so the hips are not working at all. This is the pose most of my students end up doing on day one and nothing else.
• Supta matsyendrasana, both sides, knees resting on a cushion. Period pain is often felt as low back ache more than as abdominal cramp, and this addresses that half directly.
• Balasana with the knees wide, forehead down. It is the shape people curl into anyway, made sustainable with a cushion.
• Supported setu bandhasana, a block under the sacrum, five passive minutes. This is the propped chest opener the careful traditions actually prescribe, rather than the lying still they get accused of prescribing.
• Marjariasana, slow, small range, two minutes, blankets under the knees.
• Savasana, ten minutes, with a folded blanket over the abdomen. Warmth and weight there is not superstition, it is the same reason a hot water bottle helps.
• Bhramari, nine rounds, which can be done on your side in bed and is the practice students report back on most.
• Nadi shodhana, eight rounds, when the mind needs a task.

And the deliberate omission: no strong standing sequence and no abdominal work on the first two days, not because they are dangerous but because they are unpleasant, and a practice you resent is a practice you stop. Day three onwards, most students want to stand up again, and by day five the week ahead is usually the strongest of the month.

Period pain is common and is not automatically normal. Yoga is not the right first response to any of the following, and none of them is a reason to be embarrassed about asking.

• Pain that stops you going to work or college, or that is not touched by ordinary painkillers.
• Pain that has become worse over months or years, or that has changed character.
• Bleeding that soaks through a pad or a cup in under two hours, bleeding with large clots, or periods lasting longer than seven days.
• Pain during sex, or pain when opening the bowels around the period. Those two together often point to something a doctor should look for.
• Bleeding between periods, or after sex, or any bleeding after the menopause.
• Periods that have stopped for three months or more without pregnancy.
• Fever with pelvic pain, or a sudden severe one sided pain, which is a same day problem.
• Trying to conceive without success for a year, or six months if you are over 35.

Severe period pain can be endometriosis, adenomyosis, fibroids or polycystic ovary syndrome, and every one of those has treatment. See yoga for PCOS for the one of those this site covers in its own right. A yoga class is a good thing to have alongside a diagnosis. It is a poor substitute for getting one.

First cycle: expect the practice to make the day more bearable rather than the pain smaller. Ten minutes of supported baddha konasana changes an afternoon. It does not change a diagnosis.

Second and third cycle: this is where most students notice the difference, and it usually shows up as fewer painkillers and a shorter worst day rather than as a pain free period. Several tell me the low back ache goes before the cramping does.

Three to six cycles: this is the window the trials measured in, and where the pooled effect sizes were found. Note that the trials were largely of a regular practice all month, not of poses done only while bleeding. What you do on days five to twenty five appears to matter as much as what you do on day one.

Beyond six cycles: the benefit holds while the practice holds. If your periods are painful because of endometriosis, fibroids or adenomyosis, a regular practice can make the month more liveable and will not treat the underlying condition, and anyone who tells you otherwise is selling something.

One line a day in a notebook or a phone, for three cycles. This is the part that turns a vague sense that yoga is helping into something you can take to a doctor.

1. Pain, nought to ten, on each day of bleeding. Not an average for the period. Each day separately, because the shape of the curve is what changes first: the worst day gets shorter before it gets milder.
2. Painkillers taken, counted. Doses, not a feeling about doses. This is the number doctors find most useful and the one nobody records.
3. What you actually practised, in three words. Nothing, ten minutes supported, full class. Over three cycles this tells you whether the good months were the ones with a regular practice all month, which for most of my students is exactly what it tells them.

Three cycles is the minimum honest test. One good period proves nothing and one bad one disproves nothing.

The practical reason to learn the supported versions with a teacher is that propping is a skill and it is almost never taught properly on a screen. The height of the bolster, whether the cushion goes under the thigh or under the knee, how much the sacrum needs to be lifted before a supported bridge stops being work: these are small decisions and they are the whole difference between a pose you stay in for ten minutes and one you abandon in two. Once you have been set up correctly a few times you can do it at home for the rest of your life.

The classes here are traditional yoga taught slowly by one teacher across about forty years, at a residents' association hall, to students of all ages. If you have been searching for a yoga class that will not make you announce anything to a room, the in person classes run in north Bangalore, in the hall at MSR Nagar. Say quietly on arrival that it is day one, take the bolsters, and you will be left to do the supported version while the class goes on around you. If the first two days are days when leaving the house is the problem, the live online classes solve that exactly: you practise in your own room, with your own cushions, and you can turn the camera off. The first class is free, at any point in your cycle, including day one.
