Now this is really interesting! New research has found that certain parts of the body emit measurable numbers of photons. This may open up new diagnostic techniques. But that's just the beginning. Spiritual healers from many different faiths have long said that they experience light coming from their hands, and can feel (and even see) energy from the hands, feet and heads of other people. And of course there's the classical image of halos around the heads of saints, which can be taken metaphorically, or perhaps literally, in light of this new research. I wonder if the levels of light coming from different people indicates not only health, but perhaps alertness, stress levels, or state of mind. There are many interesting possibilities for this research...
Sept. 6, 2005 — Human hands glow, but fingernails release the most light, according to a recent study that found all parts of the hand emit detectable levels of light.
The findings support prior research that suggested most living things, including plants, release light. Since disease and illness appear to affect the strength and pattern of the glow, the discovery might lead to less-invasive ways of diagnosing patients.
Mitsuo Hiramatsu, a scientist at the Central Research Laboratory at Hamamatsu Photonics in Japan, who led the research, told Discovery News that the hands are not the only parts of the body that shine light by releasing photons, or tiny, energized increments of light.
"Not only the hands, but also the forehead and bottoms of our feet emit photons," Hiramatsu said, and added that in terms of hands "the presence of photons means that our hands are producing light all of the time."
The light is invisible to the naked eye, so Hiramatsu and his team used a powerful photon counter to "see"it.
The detector found that fingernails release 60 photons, fingers release 40 and the palms are the dimmest of all, with 20 photons measured.
The findings are published in the current Journal of Photochemistry and Photobiology B: Biology.
