The human body also glows in the dark: this is the bioluminescence we have

Although it may sound impossible, humans glow in the dark, due to a biological process called bioluminescence. This happens because a living organism emits light as a result of chemical reactions.

In marine life, it's a very common phenomenon in fish, bacteria, fungi, and plants. But terrestrial bioluminescent creatures, such as fireflies, are rarer. This process serves several key functions: detecting or attracting prey, mating, or defending against a predator.

The truth is that all living beings exhibit bioluminescence, although it isn't always visible. In fact, in recent years, research has revealed that bioluminescence is possible in humans , although the light they emit is low-intensity and invisible to the naked eye.

Japanese scientists Daisuke Kikuchi and Masaki Kobayashi of the Tohoku Institute of Technology are the masterminds behind one of the leading human bioluminescence tests, conducted in 2009.

With the help of a specialized, highly sensitive camera, the Japanese managed to capture the first images of bioluminescence in humans.

One of the most striking conclusions was that the intensity of the glow varies depending on the time of day. In the afternoon, when there is more activity, it is more intense, and at night, when we sleep, it decreases. The study also concluded that our face is the brightest part of our body. Later, Dr. Gary Schwartz also conducted experiments in which he detected and recorded biophotons from plants and humans.

Recently, researchers from the University of Calgary placed hairless mice in a box and used digital cameras. The result was striking: biophoton emission decreased after the animals died.

Scientists have pointed out that it is crucial to further study bioluminescence, not only in animals but also in humans, in order to detect or even prevent diseases. However, much research is still needed to understand and verify its applications in medicine.
