90名睡眠/清醒习惯正常的受试者使用匿名自我报告问卷评估了入睡前2小时内的行为。这决定了从最初的睡眠准备开始的时间安排。记录睡前环境的性质、体力活动水平和进食行为模式，以及疲倦、情绪和安全感的自我评级。确定了估计的睡眠时间和睡眠质量。120名受试者中有90人回答。睡眠准备潜伏期为77±48分钟；入睡潜伏期为41±42分钟；熄灯入睡潜伏期为26±45分钟。预计总睡眠时间为7+/-1小时。在睡前阶段，平均噪音和光照水平较低，环境温度等级处于非常冷-非常热的中点(平均得分分别为23、28和50)。所有受试者在睡觉前都上了厕所。25%的正常受试者在入睡前的2小时内吃过零食或饭菜。60%的人设置了闹钟，27%的人洗澡或淋浴，23%的人检查门锁或窗户，49%的人在床上阅读。9%的受试者与床上的猫同睡。人类和其他动物一样，在入睡前的2小时内表现出复杂的行为序列。在睡眠开始之前，代谢活动有限的恒定环境可能容易发生体温调节变化。
Behaviour in the 2-h period before sleep onset was evaluated in 90 subjects with normal sleep/wake habits using an anonymous self-report questionnaire. This determined the timing of events from the initial preparation for sleep. The nature of the pre-sleep environment, the level of Physical activity, and patterns of feeding behaviour were recorded together with self-ratings of tiredness, mood and security. Estimated sleep duration and sleep quality were determined. Ninety of 120 subjects responded. Sleep 'preparatory latency', from the time of initial sleep preparation to sleep onset, was 77 +/- 48 min; bed time to sleep onset time (sleep latency) was 41 +/- 42 min; lights out to sleep onset latency was 26 +/- 45 min. The estimated total sleep time was 7 +/- 1 h. In the pre-sleep period, mean noise and illumination levels were low and environmental temperature rating was at the median point on a very cold-very hot scale (mean scale scores: 23, 28 and 50, respectively). All subjects went to the bathroom before going to bed. Twenty-five percent of normal subjects had a snack or meal in the 2-h period before sleep onset. Sixty percentage recorded setting an alarm, 27% had a bath or shower, 23% checked door locks or windows and 49% read in bed. Nine percent of subjects slept with a cat on the bed.Humans, like other animal species, show a complex behavioural sequence in the 2-h period before falling asleep. A constant environment with limited metabolic activity may predispose to thermoregulatory changes prior to sleep onset.
