This article reviews 35 trials that assessed the role of yoga in reducing the signs and symptoms of anxiety and stress. 25 of the trials found a reduction in stress and/or anxiety symptoms when yoga was implemented. However the authors noted that many of the studies had limitations such as small populations, lack of control groups and lack of randomisation that make their results inconclusive. In summary, the literature suggests that yoga may help to relieve anxiety and stress, but further research is needed, with larger populations, longer duration, appropriate control groups and randomisation before yoga can be recommended as a treatment.
