INTRO: You, along with all living things, produce subtle, ethereal, semi-visible light that glows until you die, according to a recent study. You would be forgiven for jumping to the conclusion that this spooky luminescence is evidence that auras exist, or something similar.
But Dr Daniel Oblak, physicist at the University of Calgary and last author of the study, told BBC Science Focus that, while auras are a metaphysical, spiritual, unscientific idea, this light is not. Instead, it's called ultraweak photon emission (UPE) and is a natural product of your metabolism.
“I normally point out that UPE is a result of a biochemical process and in that sense is related to what happens in a glow-stick, which no one suspects of having an aura,” he said. “UPE is so weak that it is not visible to the human eye and completely overwhelmed by other sources of light, unless you are in a completely dark room.”
That's not to say that shutting your curtains and turning off your lights will allow you to see your own glow. This light is between 1,000 and 1,000,000 times dimmer than the human eye can perceive... (MORE - details)
