Background: SudarshanKriya(SDK) is a powerful rhythmic breathing technique that is said to work on mental, physical, and spiritual level. It is found to be effective in improving well-being and peace of mind. Aims & objectives: The purpose of this study was to assess the effects of Sudarshankriya on heart rate (HR), systolic blood pressure (SBP), and peak expiratory flow rate (PEFR). Method: The study and control Group consisted of 50 subjects of each. Group (A) included 50 subjects who performed SDK for 3 months while Group (B) consisted 50 subjects who had not performed SDK or other yogic kriya for 3 months. Resting data were obtained from all the subjects. Then, resting heart rate (HR) was taken for 1 min, blood pressure was then measured at the 15-min interval and averaged using a Mercury Sphygmomanometer by the auscultatory method and PEFR was measured with a standard Peak Expiratory Flow Meter and MVV was measured by digital spirometer before & after SDK &Shavasana session in both groups. Result: Results show significantly decrease heart rate & systolic blood pressure & increased peak expiratory flow rate in study group. Conclusion: This study showed that short-term SDK significantly improves the cardio respiratory system at rest. Hence, it seems clear that by decreasing HR and SBP by way of breathing meditation, the work of the heart (i.e., myocardial oxygen consumption, MVO2) is decreased as well.
