Thus we propose to study whether blood pressure among prehypertensives and stage 1 hypertensives can decrease after music intervention. In order to know the mechanism underlying this reduction, we propose to study the biomarkers (indicating the function of vascular endothelium, stress hormones, oxidative stress) responsible in the causation of hypertension and autonomic function. A better understanding of alterations in these biomarkers will help us to explain the mechanism of action and validate music intervention as a tool in non-pharmacological management of hypertension.
