Abstract
Endocrine and immune response of 6 qigong practitioners and 7 non-practitioners were measured before and after 30 min meditation. Plasma cortisol, adrenalin, dopamin and β-endolphin levels decreased during meaditation, while β-endolphin of a few qigong practitioners showed a slight increase. Natural killer cell activity showed a tendency of decrease during meditation. These results suggest that the sympathetic nerve activity decrease, the stressor are reduced, and the level of brain activity also shows a tendency of decrease by meditation. It is necessarry to consider the diffence of qigong meditation technique.
