     Research has shown that music has an important effect on one's body and psyche (心灵). In fact,

there is a growing field of health care known as music therapy, which uses music to treat diseases. Even

hospitals are beginning to use music therapy. This is not surprising, as music affects the body and mind in

many powerful ways.

     Research has shown that quick music can make a person feel more alert, while slow music can

produce a calm, deep thinking state. Also, research has found that music can change brainwave activity

levels. This can help the brain to change speeds more easily on its own as needed, which means that

music can bring lasting benefits to your state of mind, even after you've stopped listening.

     Breathing and heart rates can also be influenced by music. This can mean slower breathing, slower

heart rate. This is why music and music therapy can help reduce the damaging effects of long-term stress,

greatly promoting (促进) not only relaxation, but health.

     Music can also be used to bring about a more positive state of mind by helping to keep worries away. Music has also been found to bring many other benefits, such as lowering blood pressure and reducing
