Sudarshan Kriya is a unique rhythmical breathing process that is said to have been revealed to Sri Sri Ravi Shankar during a spell of silent meditation that he had gone into for 10 days in 1982. The theory is that the kriya allows a healthy and pleasant mind to produce chemical messengers, which travel from the nervous system to the immune system, resulting in the overall betterment of both body and mind.
Effect of Rhythmic Breathing (Sudarshan Kriya and Pranayam) on Immune Functions and Tobacco Addiction
SK and P increased natural killer (NK) cells significantly (P <0.001) at 12 and 24 weeks of the practice compared to baseline. Increase in NK cells at 24 weeks was significant (P <0.05) compared to controls. There was no effect on T-cell subsets after SK and P either in the study group or among controls. SK and P helped to control the tobacco habit in 21% of individuals who were followed up to 6 months of practice. We conclude that the inexpensive and easy to learn and practice breathing processes (SK and P) in this study demonstrated an increase in NK cells and a reduction in tobacco consumption. When confirmed in large and randomized studies, this result could mean that the regular practice of SK and P might reduce the incidence and progression of cancer.
