Their emission ranges from a few up to a few hundred photons per square centimeter per second. This is completely invisible to the naked human eye.

Biophotons are involved in intercellular communication, assisting in the orchestration of complex biological rhythms.

Light in Shaping Life: Biophotons in Biology and Medicine For centuries, biology has viewed the master orchestrator of life through a strictly chemical lens. We map hormones, track neurotransmitters, and sequence DNA bases to understand health and disease. However, an emerging frontier in biophysics suggests that this chemical framework is only half the story.

The brain produces a remarkably high density of biophotons during active neural processing. Researchers are studying how disruptions in neural light signaling correlate with neurodegenerative disorders like Alzheimer's disease and Parkinson's disease.

UPE levels correlate directly with the amount of free radicals. It is used to track the efficacy of .

Medicine will likely move toward interpreting these faint signals to manage health proactively.

Proponents of the suggest cells communicate via light.
