Dawn Simulation
for Seasonal Affective Disorder
Dawn simulation uses a gradually brightening bedside light to mimic sunrise during dark winter mornings, signalling the circadian system to begin waking before alarm.
How it works
Gradual light increase suppresses melatonin and stimulates cortisol awakening response via retinohypothalamic tract, improving mood, alertness, and ease of waking in winter.
What to watch for
Less evidence than bright light therapy but easier to implement (happens during sleep). Best used as an adjunct to morning bright light exposure, not as a sole treatment for severe SAD.
