Listening to your favorite music may relax your arteries

Researchers measured arterial stiffness in 20 healthy young adults before and after they listened to 30 minutes of classical music, rock music, or nothing (as a control).

Higher "wave reflections" (another measure of artery health) are also linked to heart disease risk.
