Modern wearable devices calculate a numerical metric of sleep quality (sleep feedback), which are intended to allow users to monitor and, potentially, improve their sleep. This feedback may have a negative impact on pre-sleep cognitive arousal, and subjective sleep, even in healthy sleepers, but it is not known if this is the case. This pilot study examined the impact of poor false sleep feedback, upon pre-sleep arousal and subjective sleep continuity in healthy sleepers. A total of 54 healthy sleepers ( = 30.19 years; SD = 12.94 years) were randomly allocated to receive good, or poor, false sleep feedback, in the form of a numerical sleep score. Participants were informed that this feedback was a true reflection of their habitual sleep. Pre-sleep cognitive and somatic arousal was measured at baseline, immediately after the presentation of the feedback, and one week afterwards. Subjective sleep continuity was measured using sleep diaries for one week before, and after, the presentation of the feedback. There were no significant differences between good and poor feedback groups in terms of pre-sleep cognitive arousal, or subjective sleep continuity, before or after the presentation of the sleep feedback. The presentation of false sleep feedback, irrespective of direction (good vs. poor) does not negatively affect pre-sleep cognitive arousal or subjective sleep continuity in healthy sleepers. Whilst the one-off presentation of sleep feedback does not negatively affect subjective sleep, the impact of more frequent sleep feedback on sleep should be examined.
现代可穿戴设备会计算睡眠质量的数值指标（睡眠反馈），旨在让用户监测并有可能改善他们的睡眠。这种反馈可能会对睡前认知唤醒和主观睡眠产生负面影响，即使对健康的睡眠者也是如此，但目前尚不清楚是否真的如此。这项初步研究考察了不良的虚假睡眠反馈对健康睡眠者睡前唤醒和主观睡眠连续性的影响。共有54名健康睡眠者（年龄=30.19岁；标准差=12.94岁）被随机分配以数字睡眠评分的形式接收良好或不良的虚假睡眠反馈。参与者被告知这种反馈是他们习惯性睡眠的真实反映。在基线、反馈呈现后立即以及一周后测量睡前认知和躯体唤醒。使用睡眠日记在反馈呈现前一周和后一周测量主观睡眠连续性。在睡眠反馈呈现之前或之后，良好反馈组和不良反馈组在睡前认知唤醒或主观睡眠连续性方面没有显著差异。虚假睡眠反馈的呈现，无论方向如何（良好与不良），都不会对健康睡眠者的睡前认知唤醒或主观睡眠连续性产生负面影响。虽然一次性呈现睡眠反馈不会对主观睡眠产生负面影响，但应研究更频繁的睡眠反馈对睡眠的影响。
