X_5_28 — Circadian Rhythm Disruption: Health Consequences of Modern Light Exposure

Circadian rhythms — endogenous ~24-hour oscillations in physiology and behavior — are generated by molecular clock genes (CLOCK, BMAL1, PER, CRY) operating in virtually every cell, coordinated by the master pacemaker in
