Sleep in the elderly is known to be disturbed, and many elderly persons also complain of daytime sleepiness. The present study assessed sleep and waking behavior in 12 male (aged 63 to 86) and 12 female (ages 63 to 82) subjects. Sleep stages, respiration, and movement were recorded at night, and daytime sleep tendency was measured using the Multiple Sleep Latency Test during a single 24-hour period. Daytime sleepiness did not correlate with total sleep time or any sleep stage, but was significantly correlated with measures of sleep fragmentation. The latter included transient arousals, a measure of less than 15-sec awakenings, and sleep-related respiration disturbance. These findings suggest that fragmented nocturnal sleep is a significant cause of reduced daytime well-being in elderly individuals. The continuity of both sleep and wakefulness appears to be disrupted with age. Experimental strategies for achieving a rational sleep hygiene are discussed.
众所周知，老年人的睡眠会受到干扰，而且许多老年人也抱怨白天嗜睡。本研究评估了12名男性（年龄在63至86岁之间）和12名女性（年龄在63至82岁之间）受试者的睡眠和清醒行为。夜间记录睡眠阶段、呼吸和运动情况，并在单个24小时时间段内使用多次睡眠潜伏期测试来测量白天的睡眠倾向。白天嗜睡与总睡眠时间或任何睡眠阶段均无相关性，但与睡眠片段化指标显著相关。后者包括短暂觉醒（一种持续时间少于15秒的觉醒测量方法）以及与睡眠相关的呼吸障碍。这些发现表明，夜间睡眠片段化是导致老年人白天幸福感降低的一个重要原因。睡眠和清醒的连续性似乎都会随着年龄增长而受到干扰。本文讨论了实现合理睡眠卫生的实验策略。
