晚上使用屏幕电子设备会对睡眠产生负面影响。然而，众所周知，睡眠对大脑成熟至关重要，也是良好学习成绩的关键因素，因此在儿童和青少年时期尤为重要。尽管先前的研究报告了屏幕时间和睡眠障碍之间的关联，但它们在青少年中的因果关系仍不清楚。在大样本学生（12至19岁）中使用活动记录仪和日常问卷，我们评估了晚上的屏幕时间和1个月以上的睡眠习惯。这包括一个为期2周的基线阶段，然后是一个40分钟的睡眠教育研讨会和一个为期2周的干预阶段，其中参与者被要求在学校晚上9点后停止使用屏幕设备。在干预阶段，我们发现晚上9点后屏幕时间的减少与更早的睡眠开始时间和总睡眠时间的增加相关。后者导致改善了白天的警惕性。这些研究结果提供了证据，表明限制晚上使用屏幕是改善青少年睡眠时间的有效和有希望的方法，对白天的功能和健康有潜在的影响。
The use of screen electronic devices in the evening negatively affects sleep. Yet, sleep is known to be essential for brain maturation and a key factor for good academic performance, and thus is particularly critical during childhood and adolescence. Although previous studies reported associations between screen time and sleep impairment, their causal relationship in adolescents remains unclear. Using actigraphy and daily questionnaires in a large sample of students (12 to 19 years old), we assessed screen time in the evening and sleep habits over 1 month. This included a 2 week baseline phase, followed by a 40 min sleep education workshop and a 2 week interventional phase, in which participants were asked to stop using screen devices after 9 pm during school nights. During the interventional phase, we found that the reduction of screen time after 9 pm correlated with earlier sleep onset time and increased total sleep duration. The latter led to improved daytime vigilance. These findings provide evidence that restricting screen use in the evening represents a valid and promising approach for improving sleep duration in adolescents, with potential implications for daytime functioning and health.
