title: Effect of meditation on respiratory system, cardiovascular system and lipid profile.
abstract: In this study, respiratory functions, cardiovascular parameters and lipid profile of those practicing Raja Yoga meditation (short and long term meditators) were compared with those of nonmediators. Vital capacity, tidal volume and breath holding were significantly higher in short and long term meditators than nonmeditators. Long term mediators had significantly higher vital capacity and expiratory pressure than short term meditators. Diastolic blood pressure was significantly lower in both short and long term meditators as compared to nonmeditators. Heart rate was significantly lower in long term meditators than in short term meditators and nonmeditators. Lipid profile showed a significant lowering of serum cholesterol in short and long term meditators as compared to nonmeditators. Lipid profile of short and long term meditators was better than the profile of nonmeditators inspite of similar physical activity. This shows that Raja Yoga meditation provides significant improvements in respiratory functions, cardiovascular parameters and lipid profile.
