Abstract：
In 8 subjects the spontaneous termination of sleep was determined after repetitive exposure to either bright or dim light, between 6.00 and 9.00 h, on 3 days preceding sleep assessment. Sleep duration was significantly shorter following bright light than following dim light. During sleep the time course of EEG energy was not affected by the light treatment. Analysis of the time course of body temperature during sleep indicated an earlier rise of body temperature following the bright light treatment. In terms of the two-process model of sleep regulation this can be interpreted as a direct effect of light on the circadian phase of the wake up threshold.
摘要：
在8名受试者中，在反复暴露于强光或弱光后确定了自发的睡眠终止。在6.00和9.00h之间，在睡眠评估前3天。亮光后的睡眠时间明显短于暗光后的睡眠时间。在睡眠期间，EEG能量的时间过程不受光照治疗的影响。对睡眠过程中体温的时间过程的分析表明，在强光治疗后，体温升高较早。就睡眠调节的两个过程模型而言，这可以解释为光对唤醒阈值的昼夜节律阶段的直接影响。
