本研究探讨了14个习惯性不规律睡眠者的睡眠，自主神经功能和情绪/情感和人格状态的影响，规律的睡眠觉醒时间表。在实验过程中，睡眠监测和规律的睡眠时间表在家里进行。首先，受试者的习惯性睡眠模式被严格监测6天（第1阶段）;其次，受试者的不规则睡眠模式被规则化6天（第2阶段）;最后，受试者从其规则化的睡眠时间表恢复到其原始的习惯性睡眠时间表，并被监测6天（第3阶段）。实验室评估在白天进行，重复四次。前三次评估在第1、2和3次会议后的几天进行。第四次测量（第4阶段）是在初始不规则睡眠模式条件下进行的，在第二次不规则睡眠时间表开始后约6个月进行。结果，在为期6天的规律化睡眠时间表后，并持续到第3次会议，观察到白天副交感神经活动和消极情绪（即紧张焦虑、愤怒敌意和疲劳）显著减少。然而，副交感神经活动，以及负面情绪的表现，恢复到他们的初始水平时，测量6个月后。另一方面，睡眠和人格状态并没有随着睡眠规律的改变而改变。然而，白天疲劳水平的降低表明，在规律化的睡眠时间表下，进一步的睡眠改善可能难以检测到，因为受试者是没有睡眠障碍的健康大学生。
The present study examined the effects of regularizing sleepwake schedules on sleep, autonomic function and mood/emotional and personality states in 14 habitually irregular sleepers. During the experiment, sleep monitoring and regularized sleepwake schedules were conducted at home. First, the subjects' habitual sleepwake patterns were strictly monitored for 6 days (Session 1); second, subjects' irregular sleepwake patterns were regularized for 6 days (Session 2); and finally, subjects reverted from their regularized sleepwake schedules to their original, habitual sleepwake schedules and were monitored for 6 days (Session 3). Assessments in the laboratory, which were conducted in the daytime, were repeated four times. The first three assessments were carried out on the days following Sessions 1, 2, and 3. The fourth measurement (Session 4), which was conducted under the original irregular sleepwake pattern condition, was performed approximately 6 months after initiation of the second irregular sleepwake schedule. In results, significant reductions in daytime parasympathetic activity and negative mood, i.e. tensionanxiety, angerhostility, and fatigue, were observed after the 6-day regularized sleepwake schedule and extending through Session 3. However, the parasympathetic activity, as well as negative mood manifestations, returned to their initial levels when measured 6 months later. On the other hand, sleep and personality states did not change in response to alternations in sleepwake regularity. However, the reduction of daytime fatigue level suggests a possibility that further sleep improvements might be difficult to detect under the regularized sleepwake schedule because the subjects were healthy university students without sleep disorders.
