Cardiovascular disease (CVD) remains a leading global health concern, necessitating comprehensive strategies that include medical treatment, risk factor management, and lifestyle changes. Emerging evidence suggests that music may offer an additional supportive role in promoting cardiovascular health.
Historically, the therapeutic use of music dates back to ancient times, with the Greek philosopher Pythagoras employing music to address physical and psychological conditions. The formal study of music therapy began in 1918 at Columbia University with the introduction of a course titled “Musicotherapy.” Recent scientific investigations have explored how music can influence cardiovascular function through both physiological and psychological pathways.
Research indicates that listening to slow-tempo, low-intensity music—often classical or relaxing in nature—can activate the parasympathetic nervous system, resulting in lowered heart rate and blood pressure. This effect is believed to be mediated by the release of endogenous opioids and oxytocin, hormones associated with relaxation and social bonding. Conversely, fast, high-energy music may stimulate the sympathetic nervous system by triggering stress hormones such as cortisol and epinephrine, which can elevate heart rate. Additionally, music has been shown to improve heart rate variability (HRV), a marker of autonomic nervous system adaptability and cardiovascular resilience.
Clinical studies have demonstrated benefits of music for patients with coronary heart disease. A meta-analysis found that music listening reduced stress, heart rate, and blood pressure in these patients. Music has also been used effectively during cardiac catheterization procedures to alleviate anxiety. Furthermore, postoperative cardiac patients receiving music therapy reported decreased anxiety and pain levels, reduced reliance on analgesics, and fewer side effects related to opioid medications.
One promising application is incorporating music into cardiac rehabilitation programs. Music can help improve patient tolerance for rehabilitation exercises, uplift mood, and enhance adherence to prescribed routines. Its dual role—either calming anxiety or providing motivational support—makes it a versatile adjunct in rehabilitation settings.
While studies suggest that about 30 minutes of relaxing music may provide cardiovascular benefits, experts caution that music should not replace established prevention and treatment strategies, including physical activity, a heart-healthy diet, smoking cessation, medication adherence, and regular medical monitoring. Instead, music may serve as a complementary component within a holistic approach to reducing CVD risk.
As part of ongoing efforts to raise awareness about heart health, this year’s World Heart Day emphasizes the continuous rhythm of life and health. The metaphorical connection between music’s beats and the heartbeat underscores the potential for incorporating music into strategies aimed at improving cardiovascular outcomes.
