Does yoga help with depression in PCOS?
A 12-week randomized trial found a 6-point drop
Yoga and depression in PCOS: a 12-week randomized trial at AIIMS found a 6-point drop in depression scores, large enough to count as clinically meaningful
In this story
Researchers at India's top medical institute put 75 women with PCOS into one of two groups for 12 weeks. One group practised yoga five days a week with a therapist. The other was asked to walk briskly for an hour, five days a week, at home. Both groups were doing something real, which makes the comparison a fair one. By week 12, depression scores in the yoga group had dropped by 6 points, while the walking group barely moved, and that gap was statistically significant. Six points is the part worth pausing on: researchers generally consider a change of about 5 points on this scale to be clinically meaningful, meaning you'd expect to actually feel it. The yoga group also saw hormonal shifts, with LH, the LH to FSH ratio, and AMH all improving more than in the walking group.
The numbers that matter
The walking comparison group dropped 1.4 points over the same period, which was not statistically significant.
Can we actually trust this?
Yes, and this one is better built than most. It was registered with India's clinical trials registry before it started, which is the single best signal that researchers weren't fishing for results after the fact. It ran at AIIMS New Delhi, the country's leading medical institute, with ethics approval on file. Women were randomly assigned using a proper randomization tool. And the comparison group wasn't sitting idle: they were asked to walk briskly for an hour, five days a week, so this is yoga measured against real activity rather than against nothing. That's a higher bar than most yoga research sets for itself.
Now the honest part. Sixty-one women finished, which is small, and the study wasn't blinded, so everyone knew which group they were in. That matters especially for a self-reported depression score, where knowing you're in the "treatment" group can nudge results on its own. The researchers measured a lot of things (hormones, oxidative stress, inflammation, cellular markers) without adjusting for the fact that testing many outcomes at once produces some positive results purely by chance. The testosterone finding, which the paper's summary highlights, was only about a 4% drop and wasn't significant when the two groups were compared head to head, so we've left it out. There are also a few sloppy details in the results tables. And the study was funded by the government ministry that promotes yoga, which doesn't invalidate anything but is worth knowing. The depression result is the strongest thing here, both in size and in how clearly it separated the groups, which is why we've built the issue around it.
Does this apply to you?
This study is most relevant if:
- You have PCOS diagnosed by Rotterdam criteria
- You're between 18 and 40
- Your BMI is around 25 to 26
- You're physically able to do yoga postures
- Low mood is part of your PCOS experience
Average depression scores at the start were in the mild-to-moderate range, so these were women genuinely struggling, not just having an off week.
Why this matters
Yoga gets recommended to women with PCOS constantly, usually as a vague suggestion to relax, and it's easy to hear that as being told your symptoms are a stress problem. This study is more interesting than that, because it didn't compare yoga to doing nothing. It compared it to an hour of brisk walking five days a week, which is real exercise and roughly what most guidelines would suggest. Both groups moved their bodies consistently for twelve weeks. Only the yoga group's mood changed meaningfully, and alongside it came shifts in LH, the LH to FSH ratio, and AMH, the hormonal machinery underneath PCOS rather than just the feeling. The researchers also looked deeper, at markers of inflammation, oxidative stress, and how well cells produce energy, and found differences there too. Those findings are early and hard to interpret, but they point at something worth saying plainly: the benefit here doesn't look like it's only about relaxing. Something about the combination of movement, breathing, and stillness appears to do work that walking alone didn't do, at least over twelve weeks in this group of women.
If you want to try this
- Know what the full protocol was, then scale it.
Five sessions a week, 90 minutes each, for 12 weeks, led by a yoga therapist. That's a serious commitment, and it's fair to say most people can't start there. The honest read is that this is what produced these results, not that anything less is pointless.
- The session had a specific shape.
Roughly: a few minutes of joint loosening, sun salutations, then standing, seated, prone, and supine postures, about 25 minutes of breathing practice, meditation, and a closing discussion. The breathing work took up more time than any other single component, which is notable if you'd assumed yoga meant mostly postures.
- Start with two or three sessions and build.
The trial itself noted that longer, more demanding programs come with higher dropout. A practice you keep doing at three days a week beats a five-day plan you abandon in month two.
- Don't skip the breathing and stillness.
If you're short on time, the temptation is to keep the postures and cut the rest. Given that the walking group got plenty of physical movement and didn't see the same mood change, the non-physical parts may be doing real work here.
- Give it the full 12 weeks before judging.
Everything was measured at the start and at week 12, so there's no evidence about when changes begin to appear. A quiet first month tells you nothing.
- Keep any support you already have.
Participants started with depression scores in the mild-to-moderate range, and this was a study of yoga alongside ordinary life, not a replacement for care. If low mood is weighing on you, please talk to a clinician or someone you trust. Yoga can be part of the picture, not the whole of it.
FAQ
- Does yoga help with depression in PCOS?
- In this 12-week trial it did. Depression scores fell by 6 points in the yoga group compared with 1.4 in a group asked to walk briskly instead, and the difference between groups was statistically significant. A change of around 5 points on this scale is generally considered clinically meaningful. The study was small and unblinded, so it's encouraging rather than definitive.
- Is yoga better than walking for PCOS?
- For mood in this study, yes. Both groups exercised five days a week for 12 weeks, and only the yoga group saw a meaningful drop in depression scores along with improvements in LH, LH/FSH ratio, and AMH. That said, this is one trial of 61 women, and walking has plenty of well-established benefits of its own.
- How much yoga do you need for PCOS?
- The protocol here was 90-minute sessions, five days a week, for 12 weeks, supervised by a yoga therapist. That's the dose that produced these results. Whether less would work isn't something this study can answer.
- What is AMH and why does it matter in PCOS?
- Anti-Müllerian hormone is produced by small follicles in the ovaries and tends to run two to three times higher in women with PCOS. Elevated AMH is linked to the difficulty follicles have maturing and releasing an egg, which is part of why cycles become irregular. In this trial, AMH fell more in the yoga group than the comparison group.
- What is the LH to FSH ratio?
- Luteinizing hormone and follicle-stimulating hormone are the two pituitary hormones that drive the menstrual cycle. In PCOS, LH is often elevated relative to FSH, which contributes to excess androgen production and disrupted ovulation. In this study, LH fell and FSH rose in the yoga group, bringing the ratio down.
How Sachi can help
Here's the thing this study can't tell you: whether yoga will do for you what it did for these 61 women. The only way to answer that is to track it yourself. Sachi pulls your exercise in from Apple Health so your sessions log themselves, and sits that alongside how your mood has actually been, week by week.
That pairing is the whole point with something like this. Twelve weeks is long enough that you won't remember how you felt in week one, and mood drifts with sleep, cycle, work, and everything else. Seeing your practice and your mood side by side over three months turns a vague sense that something might be helping into a pattern you can actually read, and it gives you something concrete to bring to your doctor. Some of this is live today and some is still being built. You can follow along or join the beta at sachi-health.com.
