Effect of yoga on different aspects of mental health. Indian Journal of Physiology and Pharmacology. 2012 Jul-Sept; 56(3): 245-254.http://imsear.searo.who.int/handle/123456789/146116State anxiety, somatization of stress, quality of life, self-rated quality of sleep, and discomfort due to over-breathing which occurs when stressed were studied. Out of a total of 140 participants, seventy participants self-selected to be in a yoga group for stress relief (group mean age±SD, 33.0±6.5 years; 37 males). Seventy age and gender matched participants were in a control group. State anxiety, somatization of stress, quality of life, discomfort and self-rated quality of sleep were assessed using the State-Trait Anxiety Inventory, Symptom Checklist-90-R, SF-12, Nijmegen Discomfort Evaluation Scale and a Sleep Rating Questionnaire respectively. Assessments were made at the beginning and end of the week. Repeated measures ANOVAs with Bonferroni adjusted post-hoc analyses showed a significant decrease in state anxiety (P<0.001), somatization of stress (P<0.01), improved health-related quality of life (P<0.01), self-rated quality of sleep (P<0.01), and decrease in discomfort due to over-breathing (P<0.001). No changes (except decreased discomfort due to over-breathing; P<0.01) occurred in the control group. This study suggests that a brief yoga program may be beneficial in decreasing anxiety, somatization of stress and discomfort, improving health-related quality of life and self-rated sleep quality.enyogastate anxietysomatization of stressquality of lifeself-rated sleepArticle
