The human body can glow

According to the American Life Science website, scientists have discovered that the human body emits a kind of weak light visible, the intensity of the light fluctuating in a day.

Previous studies have found that the human body emits visible light, but 1000 times weaker than the intensity of light that we see with the naked eye, all animals can also play very weak light. It is thought to be the result of free radicals involved in biological chemical reactions. The type of visible light is not the same as infrared rays, because infrared rays are not visible light.

To learn more about this type of visible light, Japanese scientists used a super-sensitive camcorder that can test single photonics. 5 healthy young people in their 20s are arranged to experiment continuously for 3 days, every day from 10 am to 10 pm, every 3 hours, standing bare in front of the camera 20 minutes, there is no light in the room. light in.

Researchers have found that the intensity of light emitted from the body fluctuates up and down, the intensity of light emitted is weakest at 10 am, and is strongest at 4 pm, then gradually become weak. Such findings suggest that the release of light and biological clocks has a relationship, potentially related to the body's fluctuating metabolic processes throughout the day .

The spot glows the most in the face compared to other positions, possibly because the face is exposed to more sun exposure than other parts, the black pigments in the skin have a fluorescent component. This can increase light energy.

Okamura Ren, a biologist at Japan's Kyoto University, said that although this low light is related to the body, the findings suggest that those cameras with low light can help the home. Science discovered some medical problems.

Masaki Kobayashi, Northeastern Honshu University of Industrial Biology photologist, said: " If you can see the surface of the body emitting light, you will be able to see the whole thing. condition of the body . "
