When Human body glows brightest ?

The human body emits a visible light in very small quantities at levels that rise and fall as the day progresses, experts have found.
Previous studies have shown that our body emits visible light, 1,000 times less intense than the levels to which our naked eyes are sensitive. Such a phenomenon is not just restricted to humans, virtually all living creatures emit very weak light, which is thought to be a byproduct of biochemical reactions involving free radicals. In order to know more about this faint visible light, researchers in Japan used extra ordinarily sensitive cameras which were capable of detecting single photons, reports Fox News.
To reach the conclusion, five healthy, young male volunteers were placed bare-chested in front of cameras in complete darkness Experts found that the body glow rose and fell over the day, with its lowest point at 10am and its peak at 4pm, dropping gradually after that. The findings suggest there is light emission linked to our body clocks, most likely due to how our metabolic rhythms fluctuate over the course of the day. Also, researchers found, that faces glowed more than the rest of the body. The explanation for this maybe that faces are more tanned than the rest of the body, since they get more exposure to sunlight.
Researcher Hitoshi Okamura, a circadian biologist at Kyoto University in Japan said that the finding suggests cameras that can spot the weak emissions could help spot medical conditions.
