Evidence suggests that music therapy is beneficial for all individuals, both physically and mentally. Benefits of music therapy include improved heart rate, reduced anxiety, stimulation of the brain, and improved learning. Music therapists use their techniques to help their patients in many areas, ranging from stress relief before and after surgeries to neuropathologies such as Alzheimer's disease. One study found that children who listened to music while having an IV inserted into their arms showed less distress and felt less pain than the children who did not listen to music while having an IV inserted. Studies on patients diagnosed with mental health disorders such as anxiety, depression, and schizophrenia have shown a visible improvement in their mental health after music therapy. The National Institute for Health and Care Excellence (NICE) have claimed that music therapy is an effective method in helping individuals experiencing mental health issues, and more should be done to offer those in need this type of help.
