Listening to a cheerful favourite tune has a beneficial effect on blood vessels, widening them and protecting them against heart disease, researchers found.
Stressful or disturbing music, on the other hand, narrows the arteries and may be bad for the heart.
Most participants in the American study found John Denver-style country music the most uplifting, while “heavy metal” rock made them anxious.
Joyful music was thought to trigger the release of endorphins, brain chemicals linked to emotion that are known to induce feelings of well-being.
We don’t know what “heavy metal rock music” this study used, but my guess is they picked something loud and pointless like Slipknot.
On the other hand, music that shows power and beauty in darkness, like death metal and black metal, is both dark and uplifting.
It keeps the arteries from clogging by both widening and contracting them, if the study above is to be believed.
