Scientists have recently discovered that living things including human beings actually emit a light that is 1,000 times less concentrated than the form of light the naked eye is able to view. Japanese scientists used an extra sensitive camera to pick up these miniscule light rays that are able to detect single photons. In the study, young men were placed bare-chested in front of cameras in total darkness “for 20 minutes every three hours from 10 am to 10 pm for three days.” The amount of emitted light appeared to rise and fall throughout the day, reaching its lowest point at 10 am, peaking at 4 pm and then steadily dropping after that. Furthermore, faces seemed to glow the most, due to their exposure to sunlight. Researcher Hitoshi Okamura thinks that, since the emission of this light is linked to our metabolism, this new discovery could be used to detect certain medical conditions.
