Abstract

It is known that biological tissues and cells exhibit ultraweak photon emission of the order of 10^-14 W or less without external or artificial stimulation. Most of these phenomena so far are known to be associated with lipid peroxidation and processes involving active oxygens and relevant free radicals. The detailed mechanisms of such ultraweak photon emission are now being studied in our group. As part of this research, we are investigating ultraweak emission, called biophoton, originating from human beings, and we have detected the chemiluminescence of human breath without the addition of any other substance. Human breath contains various sorts of molecules, thus reflecting the pulmonary condition.
