A study presented at the American Heart Associated Scientific Sessions found showed that when volunteers listened to music that made them feel joyful, their blood vessels dilated by 26%. When your blood vessels relax your blood pressure goes down and your blood flows more freely. Other ways to induce this effect is to take the amino acid arginine, which increases dilation by increasing production of nitric oxide. (This is similar to how Viagra works, by preventing breakdown of nitric oxide).
