根据下面材料，回答题。 Music Used as a Healing Therapy 1 Music has long been used to treat patients suffering from different problems. In 400BC, its healing properties were documented by the ancient Greeks. More recently, in both world wars in the last century, medical workers used music therapy (疗法) with people suffering from trauma (外伤). Currently, it is used as a treatment for many diseases, such as cancer, and it has also been used by patients with long-term pain and learning disabilities. 2 There is growing evidence that music can cause physical changes to the body which can improve our health. In the Welcome Trust Study, which took place over three years at the Chelsea and Westminster hospital in London, patients were asked to listen to musical performances. As a result, it was found that stress levels were significantly reduced, recovery times were improved, and fewer drugs were needed. 3 These very positive results are partly due to general well-being (良好的健康状况). It is already accepted that when people feel happy and have a positive approach to life. They are more likely to feel better and recover from disease quickly. Music increases this feeling of joy and adds to the recovery process. 4 However, not all these benefits can be attributed to an increase in general well-being. Music has other effects which have not yet been understood. According to Professor Robertson, a scientist and musician, some effects of music are mysterious and are, therefore, being investigated further. It has been suggested that the sounds and rhythms of music help stimulate the brain and send electrical messages to the muscles. 5 Science, however, demands facts and hard evidence. Many in the medical profession have not yet recognized the healing benefits of music, since reports have been based mainly on various stories of evidence. These new studies could provide proof to doctors that music is a suitable treatment for many conditions. One day doctors may even "prescribe" (开处方) music, but that could be a long time in the future.
