Human hands emit light

According to recent research, all parts of the human hand emit light, but the fingers glow more. This finding reinforces a previous study that suggests that most living things, including plants, emit light.

Japanese scientist Mitsuo Hiramatsu, who led the study, said the human hand is not only a part of the body that glows with the release of photons, but also the forehead and the soles of the feet emit an amount. photon. He added that the presence of multiple photons means that our hands always produce light. But this light is invisible to the naked eye, so Hiramatsu must use a powerful photon counter to see the light.

This counting device reveals nails that produce 60 photons, fingers that secrete 40 photons and palms that are the dimmest with only 20 photons. This discovery was published in Photochemistry and Photobiology .

Scientist Hiramatsu is unsure why the nails glow more strongly than other parts of the hand, but he said: ' Perhaps due to the optical window nature of the nail ', means that the nail works. like a prism radiating light. Hiramatsu and his colleague Kimitsugu Nakamura experimented with some subjects holding plastic tubes containing hot or cold water to measure the amount of photons released from their hands.

The two researchers also pumped oxygen or nitrogen gas into the tube to where the test subjects placed their hands to analyze. It is the warmth that increases the activity of producing photons when oxygen is pumped in. When applying mineral oil on the hand, the light also emits much.

Based on these results, the two scientists argue that it is a kind of chemical glow, that is, the glow based on a chain of chemical reactions, like the glow of fireflies. They believe that 40% of the light emitted by a chemical reaction occurs when our hand skin reacts with oxygen.

For mineral oil to penetrate the skin of the hands to increase brightness, the two Japanese scientists believe that 60% of this light is produced by the chemical reaction that takes place inside the skin. Fritz-Albert Popp, the world's leading expert in bio-related photons at the International Institute of Physical Biology (Germany), agrees with the Japanese discovery and doesn't find it surprising. He said: ' We can find a clear correlation between the phenomenon of light and the degree of disease in humans '.

Popp and Hiramatsu hope that future research will reveal more about the phenomenon of emitting photons in humans and paving the way for many applications in medical diagnostics due to illness affecting the release of photons.
