摘要：

In this study the effects of bright light (BL) on the rhythms in body temperature plasma melatonin plasma cortisol and subjective alertness in 34 shift work nurses at a university hospital were assessed They were exposed to very BL (4500 lx) during 2 breaks (21 15-22 00 and 3 15-4 00) or dun light (300 lx) The subjects were studied under 24 h of realistic conditions during which their plasma cortisol and melatonin were measured at 3 h intervals their body temperature was also measured during and after night shift work Subjective alertness was evaluated with the Karolinska sleepiness scale Administration of BL significantly suppressed night tune melatonin levels A one way ANOVA revealed that BL tended to increase cortisol levels and body temperature and significantly unproved alertness These results demonstrate that phone stimulation in a hospital setting can have a powerful Influence on the adjustment of the circadian system
