Yoga teachers and students often report that yoga has an uplifting effect on their moods, but scientific research on yoga and depression is limited.
To examine the effects of a short term Iyengar Yoga course on mood in mildly depressed young adults.
Young adults pre-screened for mild levels of depression were randomly assigned to a yoga course or wait-list control group.
College campus recreation centre.
Twenty eight volunteers ages between 18 to 29. At intake, all participants were experiencing mild levels of depression, but had received no current psychiatric diagnosis or treatments. None had significant yoga experience.
Subjects in the yoga group attended two 1-hour Iyengar Yoga classes each week for 5 consecutive weeks. The classes emphasized yoga postures thought to alleviate depression, particularly back bends, standing poses and inversions.
Main outcome measures
Beck Depression Inventory. State Trait Anxiety Inventory, Profile of Mood States, morning cortisol levels.
Subjects who participated in the yoga course demonstrated significant decreases in self-reported symptoms of depression and trait anxiety. These effects emerged by the middle of the yoga course and were maintained by the end. Changes also were observed in the acute mood, with subjects reporting decreased levels of negative mood and fatigue following yoga classes. Finally there was a Trent for higher morning cortisol levels in the yoga group by the end of the yoga course, compared to controls. These finding provide suggestive evidence of the utility of yogasanas in improving mood and support the need for further studies with larger samples and more complex study designs to more fully evaluate the effects of yoga on mood disturbances.
