The following are some of effects of music, which help to explain the effectiveness of music therapy：

　　Brainwaves：Research has shown that music with a strong beat can stimulate (刺激) brainwaves to resonate (共振) along with the beat.Research has also found that the change in brainwave activity levels that music can bring can also enable 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：Other bodily functions will change with changes in brainwaves.This can mean slower breathing, slower heart rates, and an activation(激活) of the relaxation response.This is why music and music therapy can help prevent the damaging effects of stress, greatly promoting not only relaxation, but health.

　　The state of mind：Music can also be used to bring a more positive state of mind.This can help prevent the stress response from hurting the body, and can help keep creativity and optimism levels higher.

　　Other benefits：Music has also been found to bring many other benefits, such as lowering blood pressure, boosting immunity (免疫力) and more.With so many benefits and such great physical effects, it's no surprise that so many are seeing music as an important tool to help the body stay healthy.
