Listening to your favourite music may be good for your health. Researchers at the University of Maryland School of Medicine have shown that the emotions aroused by joyful music have a healthy effect on blood-vessel function.
When subjects chose and listened to music that made them feel good, blood vessles dilated and blood flow increased. With stressful music, blood vessles narrowed and blood flow slowed.
The team had previously shown laughter was good for health, and wondered if emotions "such as those evoked by music have a similar effect," says lead investigator Dr. Michael Miller.
Results were presented at the Scientific Sessions of the American Heart Association.
