已经进行了许多研究来评估睡眠参数的可变性。首夜效应是这种变异中最重要的因素之一，已被广泛研究。然而，研究对象在家待了一段时间后返回睡眠实验室时的再适应现象尚未得到系统评估。为了在多个睡眠实验室阶段调查这种现象，我们收集了12名健康年轻受试者12个晚上的多导睡眠图数据（连续4个晚上，每个晚上3个时段，间隔至少1个月）。第一晚效应只出现在第一个周期的第一个晚上（“非常第一个晚上”），并且只对快速眼动睡眠相关的变量有意义。我们的结论是，在一个特定的方案中，健康的年轻受试者连续月经的第一个晚上的结果不需要在随后的分析中被丢弃。
Many studies have been carried out to assess the variability of sleep parameters. The first night effect is one of the most important factors in this variability and has been extensively studied. However, the readaptation phenomenon when subjects returned to the sleep laboratory after spending a certain period of time at home has been not systematically evaluated, To investigate this phenomenon across multiple sleep laboratory sessions, polysomnographic data from 12 healthy young subjects for 12 nights (three periods each of 4 consecutive nights, with a minimum of 1 month between them) were collected. The first night effect was present only in the first night of the first period ("very first night") and was significant only for REM sleep-related variables. We conclude that the results from the first nights of consecutive periods within a specific protocol with healthy young subjects need not be discarded in subsequent analyses.
