Dawn Exposure

Meaning

Dawn Exposure, within the critical context of chronobiology and hormonal health, is the intentional, immediate exposure of the eyes to natural light, specifically the low-angle, high-intensity blue light spectrum present shortly after the solar disc crests the horizon. This practice functions as a powerful, non-pharmacological intervention used to acutely signal the definitive start of the biological day to the central nervous system. It serves as the most potent and primary environmental cue for precisely setting and stabilizing the master circadian rhythm.
