Music Is Good for Your Heart, Say Scientists
Favorite melodies enhance endothelial function, as stated by a new study presented at the conference of the European Society of Cardiology in Amsterdam (Netherlands). The endothelium forms the “lining” which coats the walls of blood vessels. The substances produced by endothelium regulate the bloodstream. Patients with coronary artery disease who participated in the research were divided into three groups: the first group were the patients who exercised only, the second – those who exercised and listened to music, while the third group consisted of those who listened to music only. The main goal was to detect the effect of music on the endothelial function by monitoring the changes in indicators of blood circulation. The volunteers of the first two groups were subjected to aerobic exercise program for a period of three weeks. The participants of the second group (exercise – music) again had to follow fitness program but also to listen to their favorite music every day for 30 minutes. The volunteers of the third group had only to listen to music for 30 minutes a day. Three weeks later, the researchers found that the nitric oxide levels (which relaxes blood vessels) were increased in all three groups, while the group that combined exercise and music showed better results than the other two groups (however, the exercise group presented a greater increase in nitric oxide compared to that of simple music listening). Moreover, a significant reduction of xanthine oxidase (a substance that contributes to oxidative stress) was reported in all three groups, and the group that combined music and exercise showed the best result again. Slight decrease was observed in all three groups in levels of symmetric dimethylarginine (SDMA) and asymmetric dimethylarginine (ADMA) (that cause endothelial dysfunction). “The combination of music and exercise seemed to lead to greater improvement in endothelial function. That would possibly be linked to the improvement of the physical condition of the patients,” explains the head of the study professor Marina Deljanin. “Listening to one’s favorite music just for 30 minutes a day is associated with the improved endothelial function, which can be associated with the release of the hormones of happiness endorphins in the brain,” concludes the expert, stressing that further research is needed to study in depth the effect of music on health.
