Light Biology and Circadian Timing

The signaling role of mitochondrial light emission remains unresolved. The chlorophyll-supported human energy claim is presented as limited and exceptional rather than a general strategy. Melanopsin sensors in the eyes help regulate the body’s timing system. Light exposure, eye signaling, circadian timing, and mitochondrial energy regulation are linked. Mitochondria are responsive to light, and living systems emit biophotons.
