ABSTRACT

Lockdown is an important measure that has been globally adopted to reduce the spread of the contagious disease caused by SARS CoV-2. The imposed schedule and confinement led to extensive use of digital media and rise in sedentary activity drastically. The escalated duration of screen exposure causes disruption in sleep behavior. An online survey was conducted to comprehend the effect of lockdown on sleep behavior and screen exposure time on school children. Screen exposure time involved with various electronic gadgets was also analyzed. It was observed that the social jet lag and sleep debt were significantly less during lockdown than before it. Inertia during lockdown significantly increased. The difference between screen exposure time on weekdays before lockdown and weekends during lockdown was identified to be the highest. Three clusters based on sleep behavior and duration of screen time were identified of which Cluster 2 revealed simultaneous existence of high sleep duration and screen time. These baseline data on sleep parameters and duration of exposure to the screen will help us in devising approaches to mitigate the evident disruption this unprecedented phase has brought about.

摘要

封锁是全球为减少由 SARS CoV-2 引起的传染病传播而采取的一项重要措施。强加的时间表和限制导致数字媒体的广泛使用和久坐活动的急剧增加。屏幕暴露时间的延长会导致睡眠行为中断。进行了一项在线调查，以了解锁定对学童睡眠行为和屏幕暴露时间的影响。还分析了各种电子产品所涉及的屏幕曝光时间。据观察，锁定期间的社交时差和睡眠债务明显少于锁定之前。锁定期间的惯性显着增加。锁定前的工作日和锁定期间的周末的屏幕曝光时间之间的差异被确定为最高。基于睡眠行为和屏幕时间持续时间确定了三个集群，其中集群 2 显示同时存在高睡眠持续时间和屏幕时间。这些关于睡眠参数和屏幕暴露时间的基线数据将帮助我们设计方法来减轻这一前所未有的阶段带来的明显破坏。
