BACKGROUND Practice of Yoga causes several changes in normal physiology. Meditation has positive short and longterm rewards which include a balance of the parasympathetic and sympathetic functions.

OBJECTIVES To assess the effects of Sukha Pranayama and Bhastrika Pranayama on cardiovascular autonomic functions in normal healthy medical students. MATERIALS AND METHODS 50 male and female young healthy volunteers studying at PES Institute of Medical Sciences and Research, Kuppam belonging to age group of 17-22 years were included for the study. Parasympathetic activity was assessed by observing the heart rate changes to immediate standing from lying down position, heart rate changes during deep breathing and heart rate changes during Valsalva manoeuvre using Biopac Student Lab MP30 device. Sympathetic activity was assessed by observing blood pressure changes on immediate standing from lying down position and blood pressure changes during sustained hand grip using sphygmomanometer before and after yoga.
