Research indicates that listening to instrumental music can relieve cardiac stress. A press release reporting research by Alves, Garner, do Amaral, Oliveira and Valenti states “Stress while driving is a risk factor for the development of cardiovascular disease and sudden cardiac complications such as heart attack (myocardial infarction), according to studies published in recent years. . . . A study by researchers at São Paulo State University (UNESP) in Marília, Brazil, suggests that listening to instrumental music [while driving during rush hour], for example, may relieve cardiac stress [comparison condition was not listening to music].” Cardiac stress was estimated via measurements of heart rate variability. Study findings are published in Complementary Therapies in Medicine.
