Light Therapy (Bright Light Box)
for Seasonal Affective Disorder
Bright light therapy using a 10,000 lux light box for 20–30 minutes each morning is the most effective evidence-based treatment for Seasonal Affective Disorder, acting directly on the circadian clock.
How it works
Bright light suppresses melatonin, entrains circadian rhythms, and stimulates serotonin production in the retinohypothalamic tract — directly countering the light-deprivation trigger of winter SAD.
What to watch for
Use a CE/TGA-certified 10,000 lux light box — not a UV tanning lamp. Timing is critical: use within 30 minutes of waking for best effect. Can cause mild headache or eye strain initially.
