We glow! It is now proven that at a strength 1000 x’s lower than what our eyes can see, humans have bio-luminescence. Like jellyfish and dinoflagellates, we emit light.
All creatures have a bit of bio-luminescence. It is part of the metabolic chemical reaction in our cells. Japanese researchers Masaki Kobayashi and Daisuke Kikuchi from the Tohoku Institute of Technology, along with Hitoshi Okamura have been able to capture this in these images from a new sensitive camera called the CCD – cryogenic charge-coupled device. They mapped the levels on the upper body throughout the waking day and found that humans emit more light in the afternoon. The highest density of light was emitted in the cheeks, forehead, and neck and light did not correlate to heat. Thermal images were vastly different. One has to wonder if the hands and feet would also be as sensitive as they have the highest density of sensory neurons along with the face.
This raises the question as to what we are communicating at this invisible level. Like the lightning bug, are we unconsciously glowing for mating purposes or communication?
