Our bodies are emitting light all the time?

Scientists find that "every living thing can have a faint light."

The body of an organism can actually emit light, even so weak that the naked eye cannot see it. This phenomenon is called Biophotons, or photons, caused by biological processes within cells.

Research has shown that the cells of organisms can emit very low levels of light from chemical reactions associated with metabolism and oxidative stress. Scientists are studying whether these faint lights may help tell information about the condition of the cells, or whether they may be used in the future as some health indicators.

But this does not mean that humans fluoresce to the naked eye, and there is not enough evidence to say that biophotons are the most practical way to diagnose diseases today.

The interesting thing is that scientists are asking the new question: that the tiny levels of light emitted by cells may not be just a byproduct of body chemistry, but may have a biological role that we do not yet understand.

Evidence level: 🟢 There is scientific evidence that there is a very weak level of light emissions, but the use of disease testing or health diagnosis is still in the research stage. It should not be posted as "detected." 1% of knowledge becomes 100% fake news. 😅
