We examined phase shifts to bright morning light when sleep was restricted by delaying bedtimes. Adolescents (n = 6) had 10-h sleep/dark opportunities for 6 days. For the next 2 days, half were put to bed 4.5 h later and then allowed to sleep for 5.5 h (evening room light + sleep restriction). The others continued the 10-h sleep opportunities (sleep satiation). Then, sleep schedules were gradually shifted earlier and participants received bright light (90 min, 6000 lux) after waking for 3 days. As expected, sleep satiation participants advanced (2 h). Evening room light + sleep restriction participants did not shift or delayed by 2-4 h. Abbreviations: DLMO: dim light melatonin onset.
当睡眠时间受到限制,即推迟就寝时间时,我们观察了对明亮晨光的相位转移。6 名青少年(n=6)有 6 天 10 小时的睡眠/黑暗机会。在接下来的 2 天里,一半人被推迟 4.5 小时上床睡觉,然后允许他们睡 5.5 小时(夜间房间灯光+睡眠限制)。其他人继续保持 10 小时的睡眠机会(睡眠饱和)。然后,逐渐提前睡眠时间安排,参与者在醒来后 3 天内接受明亮的光线(90 分钟,约 6000 勒克斯)。正如预期的那样,睡眠饱和组提前了(约 2 小时)。夜间房间灯光+睡眠限制组没有移动或延迟 2-4 小时。缩写词:DLMO:暗光褪黑素开始。
