对100名无睡眠障碍的正常男性和女性的睡眠模式进行了评估，他们被分为3个年龄组：19-29岁，30-49岁和50-80岁。在所有4个研究夜晚，总实验室记录时间保持恒定。夜间觉醒的量与年龄正相关;最老年龄组的总觉醒时间为0.4。2倍于最年轻的组，主要是由于睡眠开始后觉醒时间的增加，因为睡眠潜伏期不随年龄变化。在3个年龄组中的每一个中，特别是2个最老的组，睡眠开始后的最大量的觉醒发生在记录期的最后几个小时。男性睡眠的特点是夜间觉醒次数较多，老年男性的最后觉醒时间较长;然而，两性之间的睡眠效率的其他参数没有显著差异。
Sleep patterns were evaluated in 100 normal men and women who did not complain of a sleep disorder and who were divided into 3 broad age groups: 19-29, 30-49, and 50-80 yr. Total laboratory recording time was held constant across all 4 study nights. The amount of nightly wakefulness was positively correlated with age; total wake time for the oldest age group was .apprx. 2 times that of the youngest group, due primarily to an increase in wake time after sleep onset, because sleep latency did not change with age. Within each of the 3 age groups, especially the 2 oldest groups, the greatest amount of wakefulness following sleep onset occurred in the final hours of the recording period. Sleep in men was characterized by a higher number of nocturnal awakenings, and in elderly men by a longer final awakening; however, other parameters of sleep efficiency did not differ consideralby between the sexes.
