Listening to your favorite music may be good for your cardiovascular system.

Researchers at the University of Maryland School of Medicine in Baltimore have shown for the first time that the emotions aroused by joyful music have a healthy effect on blood vessel function.

Music, selected by study participants because it made them feel good and brought them a sense of joy, caused tissue in the inner lining of blood vessels to dilate (or expand) in order to increase blood flow. This healthy response matches what the same researchers found in a 2005 study of laughter. On the other hand, when study volunteers listened to music they perceived as stressful, their blood vessels narrowed, producing a potentially unhealthy response that reduces blood flow.

The results of the study, conducted at the University of Maryland Medical Center, will be presented at the Scientific Sessions of the American Heart Association, on November 11, 2008, in New Orleans.
