We've all seen images, whether in movies or TV shows, of humans and other creatures glowing at night, thanks to infrared radiation. But while this imagery is captured due to the body heat we and other animals give off, it's different from the glow that humans emit in natural light. That's right - human bodies actually glow, emitting their own light naturally.
Of course, this occurs at very low levels, and is thus not visible to the ***** eye. A study conducted in Japan found that in a light-tight room, humans emitted light picked up by an extremely sensitive camera. The amount of light fluctuated with the time of day, likely reflecting the body's natural metabolic rhythm. Perhaps there's more truth than we realized to the concept of the "*******cy glow."
