All humans emit subtle light until they die

When people tell you you're glowing, they're not wrong

- 

You, along with all living things, produce subtle, ethereal, semi-visible light that glows until you die, according to a recent study.

Rather than a luminescent aura, this light is called ultraweak photon emission (UPE) and is a natural product of your metabolism. UPE is produced when chemicals in your cells create unstable molecules known as reactive oxygen species (ROS) as by-products of your body's metabolism.
