研究人员测量了129名没有睡眠-觉醒抱怨的健康年轻（18-29岁）成年人的日间嗜睡情况，并将其与47名年龄较大（30-80岁）健康、睡眠正常的受试者进行了比较。每组1晚在实验室呆8小时，第二天接受多次睡眠潜伏期测试（MSLT）。在1000、1200、1400、1600 h测量睡眠潜伏期，各组平均睡眠潜伏期为2 ~ 20 min，但组间潜伏期分布形态不同。年轻受试者（尤其是大学生）的平均潜伏期比年长受试者短，每个分布中最困倦的80%之间存在差异。在大学生中，那些夜间睡眠效率较高的人（前一晚）第二天比那些睡眠效率较低的人更困。夜间睡眠效率和日间困倦之间的关系表明，普通年轻人的困倦增加是由于轻度睡眠限制。
The daytime sleepiness of a large sample (n = 129) of healthy, young (age 18-29) adults with no sleep-wake complaints was measured and compared with that of a sample (n = 47) of older (age 30-80) healthy, normal sleeping, subjects. Each spent 8 h in the laboratory on 1 night and received the Multiple Sleep Latency Test (MSLT) the following day. Sleep latency was measured at 1000, 1200, 1400, and 1600 h. Mean sleep latency ranged from 2 to 20 min within each group, but the shape of the distribution of latency between groups was different. The mean latency of young subjects (particularly college students) was shorter than that of the older subjects, with the differences occurring between the sleepiest 80% of each distribution. Among the college students, those with higher nocturnal sleep efficiencies (the previous night) were sleepier the following day than those with lower sleep efficiencies. The relation between nocturnal sleep efficiency and daytime sleepiness suggests that the increased sleepiness of average young adults is due to mild sleep restriction.
