A Japanese team proved it in two thousand and nine. They put volunteers, stripped to the waist, into a light-tight room and pointed an extremely sensitive camera at them for twenty minutes at a time. The camera picked up a steady, patchy shine coming off the skin, brightest around the face. The glow is a by-product of ordinary chemistry inside your cells: reactions involving oxygen throw off single particles of light as they go.

There is a catch, and it explains why nobody ever noticed. The light is roughly a thousand times weaker than the faintest thing a human eye can detect.
