Doctor Doraiswamy says these relaxation responses can help mild depression and sleep disorders. Yoga may also provide additional benefits for people with schizophrenia and ADHD when combined with standard drugs.
Dr. Doraiswamy, says: "The benefits were of the same magnitude of the benefits we see with psychiatric medications."
