失眠症患者有一个特征：他们都很准时。新的研究表明，与呼噜打得山响的熟睡者相比，那些瞌睡间隔最短且最不规则的家伙会更及时地达到约会地点。
在一项发表于即将出版的《睡眠研究期刊》上的研究中，德国弗莱堡大学医学中心的Kai Spiegelhalder和同事安排志愿者在一家睡眠诊所里进行了通宵观察，记录了他们赴约以及刷医疗保险卡的时间。
研究人员发现，失眠症患者到来得最早并且睡眠情况也最糟糕。
之前的研究曾将失眠症与完美主义联系在一起，并且因为过于守时也是完美主义的一种形式，因此新的研究结果也支持了这种关联。
然而是否因完美主义者的特质导致了失眠症——或者说反之亦然——还需要进一步的研究。
研究人员接下来打算探究是否针对减少这种强迫行为的心理疗法有助于控制失眠症——尽管失眠症患者或许已经开始晚一点赴约了。
失眠是指无法入睡或无法保持睡眠状态，导致睡眠不足，由各种原因引起入睡困难、睡眠深度或频度过短、早醒及睡眠时间不足或质量差等，常见导致失眠的原因主要有环境原因、个体因素、躯体原因、精神因素、情绪因素等。
Time will tell: a retrospective study investigating the relationship between insomnia and objectively defined punctuality

Primary insomnia is a prevalent sleep disorder affecting approximately 3% of the general population. Studies suggest that personality traits such as perfectionism and neuroticism might be implicated in the aetiology of the disorder. However, to date, no study has investigated behavioural indicators of these factors in a hypothesis-driven manner. In the present study, we assessed punctuality as a behavioural indicator of perfectionism and neuroticism in 635 consecutive clinical patients of the sleep laboratory of the Department of Psychiatry and Psychotherapy, University of Freiburg Medical Center. The primary aim was to compare primary insomnia patients (n = 148) with another group of patients with other sleep-related diagnoses (n = 487). Primary insomnia patients arrived on average 4 min earlier when compared to other patients (P = 0.041). However, this effect failed to reach statistical significance when correcting for the influence of potential confounding variables. Of note, we found a strong relationship between polysomnographic sleep parameters and punctuality. That is, short sleep duration was associated significantly with early arrival times at the sleep laboratory (P = 0.023). These findings support the proposal that personality traits, which we predict underlie obsessive punctuality, may be involved in the aetiology of objectively defined sleep disturbances. Clinical implications of the current results for cognitive behavioural treatments of insomnia are discussed.
