Scientists discovered our bodies emit a faint visible glow — tiny light from metabolic energy that peaks around 4 PM and fades at night. This short video breaks down human bioluminescence, why metabolic reactions make you shine, and how glow intensity could reflect health, energy, or emotion. Perfect for fun fact junkies curious about circadian rhythms, bio-signals, and weird human biology. Comment "HUMAN LIGHT" if that blows your mind, and don’t forget to like and share this clip with friends who love science oddities.
