Regular aerobic exercise has been extensively studied and is known to have long-term cardiac benefits. However, did you know that listening to your favorite tune can dilate your blood vessels the same way exercise or drugs used to treat high blood pressure and cholesterol do?

Blood vessels that are able to react by dilating are termed as more “elastic.” More elastic vessels decrease the risk of atherosclerosis and blood clot formation that can lead to stroke and heart attacks.

Another gas that functions in a similar manner is nitric oxide, which is often used in the treatment of heart disease. Scientists are hoping to base future blood pressure medications on the discovery of this gas.
