The present study investigated the effect of dim white light on nocturnal plasma melatonin in males and females. Subjects were exposed to light between 2400 hr and 0100 hr. No significant gender differences were found with both 200 lux (p > 0.1) and 500 lux (p > 0.1) of light. Furthermore the amplitude of the melatonin rhythm was not significantly different with gender. This suggests that at low intensities the melatonin sensitivity to light is not differentially regulated between sexes.
本研究调查了昏暗白光对男性和女性夜间血浆褪黑素的影响。受试者在24:00至01:00之间暴露于光照下。200勒克斯（p>0.1）和500勒克斯（p>0.1）的光照下均未发现显著的性别差异。此外，褪黑素节律的幅度在性别上也没有显著差异。这表明在低强度下，褪黑素对光的敏感性在两性之间没有差异调节。
