Autonomic Functions In Raja-yoga Meditators.

ABSTRACT

Stress, an inevitable and constant feature throughout the lifetime, induces autonomic dysfunctions, for which meditation is considered to be an antidote. So the case control study was planned including 50 Raja-yoga meditators practicing meditation for 5 years and 50 age matched non-meditators. Autonomic function tests were performed and results were compared using the Student- t test. Mean values of resting HR, SBP and DBP were less in meditators. Galvanic Skin Response in meditators was significantly more (p<0.001). Mean increase BP response to Hand Grip Test and Cold Pressor Test was significantly less in meditators than non-meditators (p<0.001). Standing Lying ratio, Valsalva ratio, Inspiration Expiration ratio and 3015 ratios were significantly increased in meditators than non-meditators. From the results, there was shifting of the autonomic balance to parasympathetic side in Raja-yoga meditators, which suggests its utility to combat the ill effects of stress.
