Indian Ragas on Health - a Electrophysiological Study (RAGA-1)

Blood pressure (BP) reduced significantly after listening to Indian music among prehypertensives and hypertensives in all subjects who were given a musical piece composed on raga 'bhimpalas' (raga that normalizes BP) to be heard daily for 3 months. On retrospection into the methodology, the effect of a single raga (Bhimpalas) alone had been tested. Heart rate variability (HRV) recorded once on recruitment and followed up after 3 months failed to show any change. The acute effect of music on HRV while listening to raga bhimpalas, and the effect of all ragas listed in Gandharva veda had not been tested. Respiratory rate was not controlled (affects HRV) and EEG waves were not studied.
