A 2014 review examined 37 randomized controlled trials on yoga and cardiovascular health. The combined evidence showed that yoga produced statistically significant improvements in body mass index, systolic and diastolic blood pressure, LDL cholesterol, and triglycerides. The improvements were comparable to those seen with conventional aerobic exercise.
This is a meta-analysis, which means it looks at patterns across many individual studies. The consistency of the findings is what makes it compelling. Across different populations, yoga styles, and study designs, the cardiovascular benefits appeared reliably.
For practitioners, this reframes yoga as a cardiovascular intervention, not just a flexibility or relaxation practice. The breath-movement coordination, sustained effort in postures, and stress reduction likely all contribute. The evidence suggests that regular practice produces measurable improvements in the specific biomarkers that predict heart disease risk.
