| Key findings | Experience with yoga postures (asana) was negatively correlated with global psychological distress, anxiety, and depression symptoms, and these relationships persisted after adjusting for life stressors. Life stressors moderated the link between asana experience and depressive symptoms: no association at low stress, but significant associations at average and high stress levels. The authors suggest asana may reduce depressive symptoms particularly as life stressors increase, though further research is needed. |
Abstract
Yoga contains sub-components related to its physical postures (asana), breathing methods (pranayama), and meditation (dhyana). To test the hypothesis that specific yoga practices are associated with reduced psychological distress, 186 adults completed questionnaires assessing life stressors, symptom severity, and experience with each of these aspects of yoga. Each yoga sub-component was found to be negatively correlated with psychological distress indices. However, differing patterns of relationship to psychological distress symptoms were found for each yoga sub-component. Experience with asana was negatively correlated with global psychological distress (r = -.21, p < .01), and symptoms of anxiety (r = -.18, p = .01) and depression (r = -.17, p = .02). These relationships remained statistically significant after accounting for variance attributable to Social Readjustment Rating Scale scores (GSI: r = -.19, p = .01; BSI Anxiety: r = -.16, p = .04; BSI Depression: r = -.14, p = .05). By contrast, the correlations between other yoga sub-components and symptom subscales became non-significant after accounting for exposure to life stressors. Moreover, stressful life events moderated the predictive relationship between amount of asana experience and depressive symptoms. Asana was not related to depressive symptoms at low levels of life stressors, but became associated at mean (t[182] = -2.73, p < .01) and high levels (t[182] = -3.56, p < .001). Findings suggest asana may possess depressive symptom reduction benefits, particularly as life stressors increase. Additional research is needed to differentiate whether asana has an effect on psychological distress, and to better understand potential psychophysiological mechanisms of action.
