Endocrine and immune response of 6 qigong practitioners and 7 non-practitioners were measured before and after 30 min meditation. Plasma cortisol, adrenaline, dopamine and beta-endorphin levels decreased during meaditation, while beta-endorphin 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 necessary to consider the difference of qigong meditation technique.
