Abstract

The effects of nocturnal light (500 lux) exposure on plasma melatonin were studied in seven men suffering from unipolar depression and in seven healthy men. Both groups showed significant declines in plasma melatonin concentrations during 1 hour's light exposure. Differential group declines were not detected.
