Background: Yoga is becoming popular worldwide and many studies and systematic reviews are being published with scientific evidence of its health promoting abilities and therapeutic potential in various psychosomatic conditions. Aims and objective: This short review paper takes a bird’s eye view of some health promoting benefits of yoga with regard to different systems as understood by modern medical physiology. Possible mechanisms for such physiological, biochemical and psychological effects are elucidated with references. Conclusion: Though most of the research studies and systematic reviews give evidence of in enhancing physiological functions of virtually every system, more exhaustive and rigorous studies are still advocated required to establish these positive benefits in conclusive terms. It is important to not forget the qualitative aspects of such benefits in our quest for quantitative findings when dealing with mind-body therapies and lifestyle modifications that have preventive, promotive, rehabilitative and curative potential as an adjunct therapy.
