We have been studying the essential physiological role and fundamental characteristics of biophoton emission, which is the ultraweak light emission from almost all biological systems in various living states and considered to be an universal phenomenon occurring in nature. In this paper, we report, with several examples of experimental results including emission spectra, the detailes of methods and techniques developed for highly sensitive measurement and analysis of spontaneous biophoton emission originating from the surface of human body.
The data obtained for the first time indicated that the intensity levels of ultraweak emission, measured at the tips of left hand index and middle fingers, show a variety of individual differences, reflecting dynamic physiological states in the subjects. It was actually found that the variation in emission intensity is closely related with, for example, the activity of the thyroid gland. In addition, a periodical trend similar to circadian rhythm was reproducibly observed in the variation of emission intensity measured at the left hand fingers.
