The human body literally glows, emitting a visible light in extremely small quantities at levels that rise and fall with the day, scientists now reveal.
Past research has shown that the body emits visible light, 1,000 times less intense than the levels to which our naked eyes are sensitive. In fact, virtually all living creatures emit very weak light, which is thought to be a byproduct of biochemical reactions involving free radicals.
(This visible light differs from the infrared radiation - an invisible form of light - that comes from body heat.)

heya chris,
an egyptian meme appears in todays headlines:
In Egyptian myth, Apophis was the ancient spirit of evil and destruction, a demon that was determined to plunge the world into eternal darkness.
A fitting name, astronomers reasoned, for a menace now hurtling towards Earth from outerspace. Scientists are monitoring the progress of a 390-metre wide asteroid discovered last year that is potentially on a collision course with the planet, and are imploring governments to decide on a strategy for dealing with it.
Nasa has estimated that an impact from Apophis, which has an outside chance of hitting the Earth in 2036, would release more than 100,000 times the energy released in the nuclear blast over Hiroshima. Thousands of square kilometres would be directly affected by the blast but the whole of the Earth would see the effects of the dust released into the atmosphere.
And, scientists insist, there is actually very little time left to decide. At a recent meeting of experts in near-Earth objects (NEOs) in London, scientists said it could take decades to design, test and build the required technology to deflect the asteroid. Monica Grady, an expert in meteorites at the Open University, said: "It's a question of when, not if, a near Earth object collides with Earth. Many of the smaller objects break up when they reach the Earth's atmosphere and have no impact. However, a NEO larger than 1km [wide] will collide with Earth every few hundred thousand years and a NEO larger than 6km, which could cause mass extinction, will collide with Earth every hundred million years. We are overdue for a big one."

Last Friday I picked up a paperback (well, saved it from a rubbish pile) titled "Psychic Discoveries Behind the Iron Curtain" by Sheila Ostrander and Lynn Schroeder (c. Prentice-Hall 1970).
It explores (among other things) Bio-luminescence and what they call the Energy Body, made up of something they call Bioplasma, which curiously is affected by the energy and activity of the Sun.
Russian researchers invented a form of photography called Kirlian Photogrphy, that can be used to diagnose health based on a living thing's luminescense. This book shows magnified photos of a calm person's fingertip and an agitated, stressed person's fingertip that I promise to scan and share soon. The stressed fingertip emits much more light than the calm fingertip. The researchers called it loss of energy.
The article you link to says that a person typically glows the least at 10am and then glows more throughout the day until 4pm. If a person 'glows' less when rested and glows more when ill or fatigued, as the Russians said, this seems to match up with a typical workday: I personally have more energy at 10am than at 4pm.
FWIW my nifty book says that fatigue and illness are due to depleted bioplasma and that breathing oxygen restores it. Breathing ionized air is beneficial and speeds healing. I could reason that so is aerobic exercise.
Gotta run,
