Sleep patterns change with aging, independent of other factors, and include advanced sleep timing, shortened nocturnal sleep duration, increased frequency of daytime naps, increased number of nocturnal awakenings and time spent awake during the night, and decreased slow wave sleep. Most of these changes seem to occur between young and middle adulthood; sleep parameters remain largely unchanged among healthy older adults. The circadian system and sleep homeostatic mechanisms become less robust with normal aging. The amount and pattern of sleep-related hormone secretion change as well. The causes of sleep disturbances in older adults are multifactorial.
睡眠模式会随着年龄增长而改变,与其他因素无关,包括睡眠时间提前、夜间睡眠时间缩短、白天小睡频率增加、夜间觉醒次数和夜间清醒时间增加,以及慢波睡眠减少。这些变化大多似乎发生在青年和中年时期;健康的老年人睡眠参数基本保持不变。随着正常衰老,昼夜节律系统和睡眠稳态机制会变得不那么强健。与睡眠相关的激素分泌量和模式也会发生变化。老年人睡眠障碍的原因是多方面的。
