在一个陌生的环境中睡觉，如睡眠实验室，被认为会干扰健康人的睡眠，并可能表现出一种被称为第一夜效应的过度觉醒状态。失眠症（ID）是一种高度流行的健康问题，其特征是夜间和白天的觉醒增加。在ID患者中是否发生类似的现象尚不清楚。本研究旨在探讨一个不熟悉的环境对ID患者的睡眠的影响。MethodsIn一个不熟悉的睡眠实验室，多导睡眠图记录测试进行了连续两个晚上的ID患者和年龄和性别匹配的健康对照组（HC）。我们收集了睡眠日记和关于睡眠、医疗状况、心理状态和健康史的问卷。两组的睡眠连续性和架构进行了比较，并分析了连续两个night.ResultsID（n= 39）和HC（n= 35）的参与者表现出不同的睡眠差实验室适应暴露后，睡眠实验室。ID患者在第一夜的快速眼动（REM）潜伏期长于第二夜。HC显示N1的持续时间和百分比增加，N3的持续时间和百分比减少，REM百分比减少。其他睡眠变量显示ID和HC. ConclusionsA陌生的睡眠环境并没有加剧睡眠连续性和睡眠结构的破坏，但只影响REM潜伏期与HC相比，ID患者的第一和第二睡眠夜之间没有差异。
BackgroundSleeping in an unfamiliar environment, such as a sleep laboratory, is thought to disturb sleep in healthy individuals and could express a hyperarousal state called the first night effect. Insomnia disorder (ID) is a highly prevalent health problem characterized by increased arousal during the night and daytime. Whether or not a similar phenomenon occurs in patients with ID is unclear. This study aimed to investigate the effect of an unfamiliar environment on the sleep of patients with ID.MethodsIn an unfamiliar sleep laboratory, polysomnographic recording testing was performed for two consecutive nights in patients with ID and age- and sex-matched healthy control subjects (HC). We collected sleep diaries and questionnaires regarding sleep, medical conditions, psychological status, and health history. Sleep continuity and architecture in both groups were compared and analyzed for two consecutive nights.ResultsParticipants with ID (n= 39) and HC (n= 35) demonstrated differentially poor sleep on laboratory adaptation after exposure to the sleep laboratory. Patients with ID had longer rapid eye movement (REM) latency on the first night than on the second sleep night. HC showed increased duration and percentage of N1, decreased duration and percentage of N3, and decreased REM percentage during initial nights compared to subsequent nights. The other sleep variables showed no differences between the first and second sleep nights in patients with ID and HC.ConclusionsAn unfamiliar sleep environment does not aggravate the disruption of sleep continuity and sleep architecture but only affects the REM latency in patients with ID compared with HC.
