Study: Human Hands Emit Light
By Jennifer Viegas, Discovery News

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.

Hiramatsu is not certain why fingernails light up more than the other parts of the hand, but he said, "It may be because of the optical window property of fingernails," meaning that the fingernail works somewhat like a prism to scatter light.

To find out what might be creating the light in the first place, he and colleague Kimitsugu Nakamura had test subjects hold plastic bottles full of hot or cold water before their hand photons were measured. The researchers also pumped nitrogen or oxygen gas into the dark box where the individuals placed their hands as they were being analyzed.

Warm temperatures increased the release of photons, as did the introduction of oxygen. Rubbing mineral oil over the hands also heightened light levels.

Based on those results, the scientists theorize the light "is a kind of chemiluminescence," a luminescence based on chemical reactions, such as those that make fireflies glow. The researchers believe 40 percent of the light results from the chemical reaction that constantly occurs as our hand skin reacts with oxygen.

Since mineral oil, which permeates into the skin, heightens the light, they also now think 60 percent of the glow may result from chemical reactions that take place inside the skin.

Fritz-Albert Popp, a leading world expert on biologically related photons at The International Institute of Biophysics in Germany, agrees with the findings and was not surprised by them.

Popp told Discovery News, "One may find clear correlations to kind and degree (type and severity) of diseases."

Popp and his team believe the light from the forehead and the hands pulses out with the same basic rhythms, but that these pulses become irregular in unhealthy people. A study he conducted on a muscular sclerosis patient seemed to validate the theory.

Both he and Hiramatsu hope future studies will reveal more about human photon emissions, which could lead to medical diagnosis applications.

Has anyone ever noticed that when you turn the lights out real fast at nighttime the first thing you start to be able to see is usually your hands? I've always noticed that and now I might possibly know why:P

if you can detect 120 photons over what ever timeframe this detection of photons was conducted, especially directly after having lights on which would be pumping out trillions++ of photons per millisecond, then you my friend are the most light sensitive human to ever live.

most likely its after image re-firing in your retna.

most likely, again I have no idea what I'm talking about so disregard if I sound stupid when it comes to this.

hahaha - ok done.

it is interesting though that this study is so lame.

we emit body heat which some animals see as light which us, as bigger animals, do not.

Bats, whale, dolphins see somekind of radar image by pinging sonics constantly. Mosquitos see our body heat. We see heat also - in the form of light. Light photons are energy which is heat.

I think this Mitsuo Hiramatsu should have his funding revoked for stating the obvious without coming to a conclusion as to what those reactions that cause the release of photons are.
