Yoga for Anxiety

A substantial body of trials and reviews examines yoga as an intervention for anxiety disorders and symptoms — with findings suggestive but methodologically constrained.

Summary

Randomized trials span generalized anxiety symptoms, panic, social anxiety, and anxious depression; interventions range from integrated hatha programs to breathing-centered protocols (slow pranayama, coherent breathing).

Key findings

Meta-analyses generally report moderate short-term reductions in anxiety symptoms versus inactive or minimal controls; effects versus active comparators (exercise, CBT) are smaller and less consistent. Breathing-rate reduction and heart-rate variability improvement are the best-replicated physiological findings. Long-term data are scarce.

Methodology

Trials typically run 8–12 weeks with weekly classes plus home practice; control conditions vary widely — the principal heterogeneity source.

Criticism/Limitations

Blinding is impossible; expectancy effects are large in anxiety populations; adverse-event reporting is sparse; most studies are small.

Verification notes

• Findings summarized reflect the systematic-review literature (multiple meta-analyses, 2010s–2020s).
