Abstract
Endocrine and immune responses were measured before and after Qigong was conducted for 40 minutes, using the Guolin' New Qigong techniques called Shizen-Koukou and Chukaikou. Plasma cortisol and adrenaline levels decreased while β-endolphin, dopamine, noradrenaline, and CD4/CD8 showed a tendency to increase. It was concluded that practicing the Guolin' New Qigong techniques alleviated stress and caused sympathetic nerve activity decline. Also, when the CD4/CD8 ratio increased, the suppressor T-cells also increased, and this improved the immunity function. The results of practicing Shizen-Koukou and Chukaikou were compared, but there were no significant differences.
