Your Body Literally Glows With Light
Did you know that the human body literally glows? It emits a visible light in extremely small quantities at levels that rise and fall within the day. According to past research, the body emits visible light 1,000 times less intense than the levels which can be seen with the naked eye. In fact, almost all living creatures emit very weak light!
Scientists in Japan employed extraordinarily sensitive cameras capable of detecting single photons to learn more about this faint visible light. Five healthy male volunteers who are in their twenties were placed bare-chested in front of the cameras in complete darkness in light-tight rooms for twenty minutes every three hours.
The researchers found that the body glow rose and fell over the day, with its lowest point at around 10:00 in the morning and its peak at 4:00 PM, dropping gradually after that. These findings suggest that there is light emission linked to the body clock. This is happens due to how metabolic rhythms fluctuate over the course of the day.
Faces glowed more than the rest of the body and this might be because faces are more tanned since they get more exposure to sunlight.
