Yoga may ease depression, ADHD
A good yoga class may do more than simply tone your arms. A review of 16 studies by researchers at Duke University found that yoga might help ease sleep problems and symptoms of depression. The benefits of yoga on sleep and depression were seen even in patients who were not taking any kind of medication for their conditions. The review also found that people diagnosed with ADHD and schizophrenia found some relief from their symptoms through a regular yoga practice, though these patients were also medicated for their conditions.
According to the studies, yoga actually triggers similar biological responses in the body as antidepressants and psychotherapy, which may be why people with these conditions who practiced yoga saw a decrease in symptoms. But the studies that looked at yoga's impact on depression were done only on people with mild forms of depression, so it is unclear if it would help with more severe cases.
In any case, researchers stressed that yoga is not a substitute for professional help.
