Music to Your Heart
Reported November 14, 2008
(Ivanhoe Newswire) -- We often say certain sounds are like music to
our ears. Researchers now believe they may be music to our hearts as well.
In a new study conducted among ten healthy volunteers, they found listening
to enjoyable music significantly increased the dilation of blood vessels.
Compared to baseline readings, the average upper arm blood vessel diameter
increased by 26 percent after the participants listened to their favorite
tunes. By contrast, when study subjects were asked to listen to music they
didn’t like, their blood vessels actually contracted.
Country music most often brought on these positive changes, but the
investigators believe any music a person enjoys would probably have the same
effect.
How does listening to enjoyable music help relax the blood vessels? The
researchers chalk the finding up to a physiological reaction involving brain
chemicals called endorphins that are known to have positive effects in the
body.
The study, which builds on previous research showing laughter can also be
good for cardiovascular health, has lead the authors to believe simple
things can promote heart health.
“Needless to say, these results were music to my ears because they signal
another preventive strategy that we may incorporate in our daily lives to
promote heart health,” study author Michael Miller, M.D., director of
preventive cardiology at the University of Maryland Medical Center and
associate professor of medicine at the University of Maryland School of
Medicine, was quoted as saying.
