Research-based evidence supports the therapeutic use of music to improve the sleep quality measured by self-reported questionnaires. However, scientific knowledge of the effects of music measured using standard polysomnography in chronic insomnia adults is currently insufficient.
The objective of this study was to evaluate the effect of soothing music on objective and subjective sleep quality in adults with chronic insomnia.
Fifty participants were enrolled in a randomized controlled trial conducted in the sleep laboratory of a hospital, with 25 participants allocated to the music group and 25 to the control group. For four days, the experimental group was exposed to soothing music selected by the participants or researchers for 45 min at nocturnal sleep time, whereas the control group was not exposed to music. Sleep was measured using polysomnography (PSG) and self-reported questionnaires. A general estimating equation was applied to analyze the data.
After controlling for baseline data, the music group had significantly better scores for rested rating (p=0.01), shortened stage 2 sleep (p=0.03), and prolonged REM sleep (p=0.04) compared to the control group, shown by the generalized estimating equations. However, there was no evidence of the effectiveness of music on other sleep parameters as measured by PSG. Additional findings indicate no difference in sleep quality between those who listened to their own preferred music (n=10) and those who listened to music selected by the researchers (n=15).
The results contribute to knowledge of the effectiveness of music as a therapy to improve sleep quality in adults experiencing insomnia. Listening to soothing music at nocturnal sleep time improved the rested rating scores, shortened stage 2 sleep, and prolonged REM sleep, but has little effect on sleep quality as measured by polysomnography and self-reported questionnaires.
基于研究的证据支持使用音乐治疗来改善通过自我报告问卷测量的睡眠质量。然而，目前对于慢性失眠成年人使用标准多导睡眠图测量的音乐效果的科学知识还不够充分。
本研究旨在评估舒缓音乐对慢性失眠成年人客观和主观睡眠质量的影响。
50 名参与者被纳入了一项在医院睡眠实验室进行的随机对照试验，其中 25 名参与者被分配到音乐组，25 名参与者被分配到对照组。在四天的时间里，实验组在夜间睡眠时间暴露于参与者或研究人员选择的舒缓音乐中 45 分钟，而对照组则不接触音乐。使用多导睡眠图（PSG）和自我报告问卷来测量睡眠。采用广义估计方程来分析数据。
在控制了基线数据后，与对照组相比，音乐组的 rested rating（p=0.01）、缩短的 stage 2 睡眠（p=0.03）和延长的 REM 睡眠（p=0.04）得分显著更好，这表明音乐组的睡眠质量得到了改善。然而，PSG 测量的其他睡眠参数并没有证据表明音乐是有效的。进一步的发现表明，那些听自己喜欢的音乐（n=10）和听研究人员选择的音乐（n=15）的人之间的睡眠质量没有差异。
这些结果有助于了解音乐作为治疗失眠症成年人改善睡眠质量的有效性。在夜间睡眠时间听舒缓音乐可以提高 rested rating 评分、缩短 stage 2 睡眠和延长 REM 睡眠，但对多导睡眠图和自我报告问卷测量的睡眠质量影响不大。
