Humans emit a faint amount of light that is invisible to the naked eye, a phenomenon known as bioluminescence or physiological luminescence. This light is produced through biochemical reactions in the body, primarily in the form of weak photons emitted from the skin.
Recent research using highly sensitive cameras has confirmed that this light emissionâabout a million times less intense than what the human eye can detectâis a natural part of human physiology. Itâs thought to result from metabolic processes and cellular reactions.
The intensity of this bioluminescence varies throughout the day, with the lowest levels observed in the morning and the highest at night.
This variation is believed to be linked to the bodyâs circadian rhythms and changes in metabolic activity.
While this phenomenon isnât visible without specialized equipment, it highlights an intriguing aspect of human biology, showing that even the most mundane processes can have subtle yet fascinating scientific implications.
