From the studies of the living biological systems, it is known that they emit light (biophotons) of a very weak intensity. However, the behavior of the biophoton emission at the time of qigong has not been clarified. In this report, the authors measured biophotons emitted from the human hand and temperatures of the hand surface by thermograph, in order to clarify the correlation of qigong, biophotons, and a skin surface temperature. Although substances usually have an increase of photon intensity when temperature rises, in this experiment, the drop of the skin surface temperature during qigong and an increase of biophoton emission intensity were observed.
