Rapid Eye Movement (REM) sleep is involved in nightly emotional processing; therefore, its disruption might be associated with an impaired ability of emotional regulation during daytime. Accordingly, the aim of the present study was to evaluate the presence of emotional dysregulation in insomnia patients and to test its correlation with REM sleep features. Forty-six subjects (23 insomnia patients and 23 healthy controls) were enrolled. All subjects underwent an assessment for the evaluation of emotion dysregulation (Difficulties in Emotion Regulation Scale, DERS), sleep quality, insomnia severity, excessive daytime sleepiness, worry, rumination, depressive and anxious symptomatology. Insomnia patients underwent a nocturnal polysomnographic recording to characterize sleep macrostructure and REM sleep microstructure variables. Insomnia patients reported increased values of emotional dysregulation. REM sleep percentage and REM sleep latency significantly correlated with DERS total score, and with the subscales “Lack of Confidence in Emotional Regulation Skills”, “Difficulties in Behavioral Control” and “Difficulty in recognizing emotions”. Furthermore, positive correlations between REM arousal index and emotion dysregulation were found, whereas REM density negatively correlated with DERS. Our results suggest the presence of a relationship between REM sleep and emotional regulation in insomnia patients.

快速眼动（REM）睡眠与夜间情绪处理有关；因此，其破坏可能与白天情绪调节能力受损有关。因此，本研究的目的是评估失眠患者情绪失调的存在，并测试其与REM睡眠特征的相关性。纳入46名受试者（23名失眠患者和23名健康对照）。所有受试者均接受了情绪失调（情绪调节量表的困难，DERS），睡眠质量，失眠严重度，白天过度嗜睡，忧虑，反省，抑郁和焦虑症状的评估。失眠患者进行夜间多导睡眠图记录，以表征睡眠宏观结构和REM睡眠微观结构变量。失眠患者报告情绪失调值增加。REM睡眠百分比和REM睡眠潜伏期与DERS总分，“情绪调节技能缺乏信心”，“行为控制困难”和“识别情绪的困难”等分量表显着相关。此外，还发现REM唤醒指数与情绪失调之间呈正相关，而REM密度与DERS呈负相关。我们的结果表明失眠患者的REM睡眠与情绪调节之间存在关联。“行为控制中的困难”和“识别情绪中的困难”。此外，还发现REM唤醒指数与情绪失调之间呈正相关，而REM密度与DERS呈负相关。我们的结果表明失眠患者的REM睡眠与情绪调节之间存在关联。“行为控制中的困难”和“识别情绪中的困难”。此外，还发现REM唤醒指数与情绪失调之间呈正相关，而REM密度与DERS呈负相关。我们的结果表明失眠患者的REM睡眠与情绪调节之间存在关联。
