Studies have demonstrated that music impacts numerous parts of the brain, including those involved in emotion, cognition, sensory, and movement. In fact, music therapy for mental health has been utilized as a therapeutic aid for millennia.
Recently, researchers looked at the impact of music interventions on health-related quality of life, and tried to answer the question about the best way to help make that shift toward release, relaxation, and rehabilitation. This recent systematic review and meta-analysis (a study of studies) showed that the use of music interventions (listening to music, singing, and music therapy) can create significant improvements in mental health, and smaller improvements in physical health–related quality of life. While the researchers found a positive impact on the psychological quality of life, they found no one best intervention or "dose" of music that works best for all people.
