Maybe, for one marker. Early studies suggest yoga can lower IL-6, an inflammation signal in the blood. A 2026 meta-analysis of 8 randomized trials in rheumatoid arthritis found IL-6 fell with yoga, but TNF-alpha did not change in a clear way. Other trials found the same split, with CRP often flat.
What the new rheumatoid arthritis review found
Rheumatoid arthritis (RA) is a disease where the immune system attacks the joints. That makes it a good place to test whether a calm, slow practice can touch inflammation at all.
In 2026, a research team pooled every randomized trial they could find on yoga for RA, published from 1994 to June 2025. A meta-analysis is a study that combines the results of many trials. They found 8 trials with 651 people.
Yoga lowered IL-6 compared with the control groups. IL-6 is a signaling protein your body uses to turn up inflammation. TNF-alpha, another signal that drives RA, went down too, but not by enough to rule out chance.
Disease activity improved. Yoga groups scored better on DAS28, a standard score of how active RA is. But a questionnaire on daily tasks, like dressing or climbing stairs, showed no clear change. The authors said more and larger studies are needed.
One of the trials shows what this looks like up close. In 2023, 64 people with active RA were split into two groups. Half did yoga for 8 weeks. Everyone stayed on their usual RA medicines. The yoga group's disease scores improved, and lab tests showed lower IL-6 and IL-17, two signals that feed inflammation.
Does yoga lower inflammation in other conditions?
The pattern shows up beyond RA, though it is patchy.
In 8 trials of people with rheumatoid arthritis, yoga lowered IL-6.From a 2026 meta-analysis in Int J Rheum Dis
A 2019 review gathered 15 studies of yoga in adults with long-term illnesses tied to inflammation. IL-6 was measured in 11, CRP in 10 and TNF in 8. Most of the studies, 11 of 15, reported better inflammation markers after yoga. The review also found a dose effect. People who did more than 1,000 minutes of yoga in total saw bigger gains.
A 2018 review of 15 randomized trials came to a similar view. Yoga lowered a marker called IL-1beta, with signs that it lowered IL-6 and TNF-alpha too. The authors thought longer practice might be needed for steady results.
Two newer studies add detail. In a 2025 trial, 159 people with Parkinson's disease were split into meditation, yoga or usual care. Six months later, the yoga group had lower IL-6 than usual care. And a 2026 review of 21 exercise studies in 1,022 people with heart failure ranked tai chi and yoga among the most effective types for lowering IL-6.
Why would a slow practice touch inflammation at all? One clue is stress. A 2017 meta-analysis of 42 trials compared yoga with other active programs. Yoga was linked to lower cortisol, a stress hormone, in the evening and on waking, and to a lower resting heart rate. No study here tested whether that calmer stress system explains the IL-6 drop.
Why CRP is the sticking point
Here is where the story gets less tidy. CRP, short for C-reactive protein, is the inflammation marker most doctors test. It often stayed put.
In a 2021 trial, 84 adults with depression did hatha yoga or attended health classes. IL-6 dropped in the yoga group compared with the class group. CRP and TNF-alpha did not. The RA review saw the same split between IL-6 and TNF-alpha.
Then there is the quality problem. A 2021 review of 11 yoga trials rated 8 of them at high risk of bias. In a yoga trial, people know which group they are in, and that can shape results. The 2018 review put it plainly: the field is young, and the evidence is small.
So the honest read is this. IL-6 tends to drift down in people with a chronic illness who keep up yoga. Whether that adds up to a real health gain is not yet known.
What about hot yoga?
We found no trials that measured inflammation markers in heated yoga. What one small trial did measure was effort.
In 2018, 14 people did the same 20-minute yoga routine twice, once in a hot room near 35 °C and once at room temperature. Their hearts beat faster in the heat, at 67% of max heart rate versus 60.8%. But the oxygen they used, a direct measure of work, was nearly the same: 30.9% versus 30.5% of max. By that measure, both counted as light exercise. The heat makes yoga feel harder, but the body is not doing much more work.

The bottom line
The IL-6 signal keeps turning up: in rheumatoid arthritis, in depression, in Parkinson's disease, in heart failure. CRP and TNF-alpha mostly do not follow, and the trials are small and hard to blind. That is why we grade this Emerging. Yoga is a gentle habit with a plausible, not proven, effect on inflammation. If you enjoy it, there is a modest reason to keep showing up.
Common questions
Is yoga anti-inflammatory?
Early studies suggest it may be, mostly for one marker. In 8 trials in rheumatoid arthritis, yoga lowered IL-6, while TNF-alpha did not change by a clear amount. In a trial of adults with depression, IL-6 fell but CRP did not. And 8 of 11 trials in one review were at high risk of bias, so the case is not settled.
Can yoga trigger inflammation?
We found no trials showing yoga raises inflammation markers. The more common problem is soreness. A Cochrane review of 21 trials in people with low back pain found more side effects with yoga than with no exercise, mostly more back pain: 43 in 1,000 people versus 9 in 1,000. The risk was about the same as other exercise.
Is hot yoga anti-inflammatory?
No study we found measured inflammation markers in hot yoga. In a small 2018 trial of 14 people, the heat raised heart rate, but the body used about the same oxygen as in a room-temperature class. Both were light exercise by that measure. So there is no evidence that heat adds an inflammation benefit.
How long does it take for yoga to lower inflammation?
Likely weeks to months. In the RA trial, changes showed after 8 weeks of yoga. In the Parkinson's trial, the IL-6 drop appeared at 6 months. A 2019 review found people with more than 1,000 total minutes of practice had bigger gains. Reviewers think longer practice may be needed for steady results.
