Abstract
It has been confirmed that all living things emit external-Qi as long as they are alive. Among them we are special interest in human body, which also transmit bio field emission (BFE) in the form of electromagnetic radiation, since, hitherto, our measurements have shown existence of BFE. This time, we applied practically to human activity. We picked two human activities among them, as an activity of Qigong and Dance-therapy. We discovered that after relaxed Qigong activity, BFE signals were enhanced as almost 2〜3 times than before, and after self-creative dancing , BFE were decreased as almost 1/2 time, respectively. These renults are understood as internal-Qigong makes a human body's BFE high, because of some relaxation, and creating works such as self-creative dancing makes a body's BFE low, because of some mental stress more or less.
