Yoga and rheumatoid arthritis: what a recent study found
Researchers at Emory University explored whether regular yoga could ease the symptoms of rheumatoid arthritis and influence immune cell activity linked to joint inflammation. The study appeared in Scientific Reports and focused on changes in inflammatory pathways as people practiced yoga over a set period.
In this investigation, 64 adults with active rheumatoid arthritis were enrolled. Half performed 120 minutes of guided yoga daily for eight weeks, while the other half continued with their usual medication regimen. Disease activity was measured with the DAS28-ESR index, which combines four indicators: the number of painful joints, the number of swollen joints, the patient’s overall health assessment, and the erythrocyte sedimentation rate to gauge inflammation.
Results showed meaningful improvements in DAS28-ESR scores among those who practiced yoga. In addition, there were notable shifts in gene activity related to inflammation and a reduction in Th17 cells, a type of immune cell known to drive inflammatory processes. At the same time, the yoga group experienced an increase in regulatory T cells (Tregs), which help keep inflammation in check and support immune balance.
The researchers acknowledged a limitation: they did not compare yoga to other forms of activity, and the requirement of 120 minutes of daily practice may not suit everyone. Still, the findings suggest that yoga could be a complementary approach for some individuals with rheumatoid arthritis, potentially helping to reduce joint inflammation and improve overall well being.
Rheumatoid arthritis is an autoimmune condition characterized by joint pain and swelling, arising from the immune system attacking the joint lining. In some cases, the disease can affect other organs such as the eyes, heart, and lungs. Early signs often include persistent joint pain, tenderness, swelling or stiffness lasting six weeks or more, and morning stiffness lasting half an hour or longer. A symmetrical pattern of affected joints is common, with symptoms frequently beginning in smaller joints.
Previous research has looked at various strategies to manage symptoms and knee pain caused by mechanical impact, though this study specifically highlights the potential inflammatory benefits of a structured yoga program as part of a broader treatment plan. The work adds to a growing body of evidence supporting mind-body practices as a component of comprehensive rheumatoid arthritis care.
