"While music has long been recognized as an effective form of therapy to provide an outlet for emotions, the notion of using song, sound frequencies and rhythm to treat physical ailments is a relatively new domain, says psychologist Daniel J. Levitin, PhD, who studies the neuroscience of music at McGill University in Montreal. A wealth of new studies is touting the benefits of music on mental and physical health. For example, in a meta-analysis of 400 studies, Levitin and his postgraduate research fellow, Mona Lisa Chanda, PhD, found that music improves the body's immune system function and reduces stress. Listening to music was also found to be more effective than prescription drugs in reducing anxiety before surgery (Trends in Cognitive Sciences, April, 2013)."
