Music often changes people's mood or behavior. For example, a soothing lullaby makes a baby stop crying. Listening to Beethoven's symphony Destiny is always exciting. On the other hand, music is also closely related to human health. According to Yahoo News, the head of the American Music Therapy Association recently said that under the guidance of professionals, music can often improve a person's physical, emotional or cognitive health, and a large number of new studies provide strong scientific evidence for these claims. Listening to music while walking can lose more weight. Christopher Capuano, head of the Department of Psychology at fairey Dickens University in the United States, reported that exercise is very difficult for fat people, but in our research, walking with music seems to really motivate women to take their own steps and stick to the distance. His research team has worked out a weight-loss plan for overweight women (body mass index is between 26. 1 and 4 1.7), including diet, aerobic exercise and participation in group activities. As part of the project, the research team provided portable CD players for half of the women to use while walking. The other half of the women didn't bring CDs. The results showed that compared with women without CD, those who walked and listened to music lost significantly more weight, and fewer people gave up their weight loss plan halfway. Listening to concerts can alleviate the pain of patients. In his forthcoming book, Dr. Li Pingbin Ponis, medical director of Canyon Ranch spa in the United States, reported that a Korean study found that music therapy can really relieve the pain of patients with leg fractures. He also cited a study published in the journal Clinical Research of Cardiology, which showed that listening to music during uncomfortable catheterization greatly reduced the pain of patients. Patients with music are more likely to control their blood pressure. Mark Judas Tramaux, a musician and neuroscientist at Harvard Medical School, is exploring how music can benefit mankind in addition to entertainment. According to Tramaux, a study shows that it is not so difficult for people to pedal while listening to music compared with when they pedal quietly. Studies have shown that heart patients living in intensive care units with music need less doses of antihypertensive drugs than patients living in wards without music. Tramaux personally experienced a set of blood pressure lowering device called Res-perate, which can adjust breathing with the rhythm of music and is a good auxiliary method to control blood pressure. Music therapy can make Alzheimer's patients more cooperative in treatment. A one-month music therapy study conducted by the Medical College of the University of Miami in the United States found that during the study period, the contents of melatonin, epinephrine and norepinephrine (all natural emotional enhancers) in the blood of all patients increased significantly. People who participated in this study slept better and became more cooperative and active. Music can relieve the anxiety of cancer patients. According to Pratima Lech, a health care doctor of the World Anti-Doping Agency, "A preliminary study conducted by Ohio State University found that the sound of Vedas (the oldest religious document in India) can slow down the development of tumors in mice." Similarly, a study of patients receiving highly toxic high-dose chemotherapy and autologous stem cell transplantation at Memorial Si Long-Kettering Comprehensive Medical Service Center in the United States proved that trained music therapists can significantly reduce patients' anxiety.
