Study limitations included a range of symptom severity, variable type and length of yoga, lack of participant blinding, wait-list rather than active-treatment controls, and a lack of consistent long-term follow-up data. The RCTs didn’t report any adverse effects of yoga, and yoga is considered safe when taught by a competent instructor.3,4
