摘要
近年来,电子媒介的迅猛发展为人们的生活增添了便利和趣味性,但与此同时,昼夜不合理地使用电子媒介如手机,平板等也对人们的身心健康造成困扰。新近的研究发现,夜间睡前使用平板阅读会显著延迟人们的入睡时间,REM时间减少,褪黑素分泌减少且分泌时间延迟,次日觉醒后的睡意更大。然而,也有研究发现,夜间高照度的光照和蓝光光照能明显抑制机体褪黑素的分泌并显著提升人体的警觉性。本研究拟通过设置夜间不同的家居照明环境,寻找睡前使用电子设备阅读时家居光环境与视觉舒适度的最优拟合参数,以及使用不同光学属性(含和不含蓝光)的电子设备对机体生物节律、情绪及睡眠结构(包括入睡时间,睡眠惯性,觉醒警觉性)等的影响。实验采用两因素混合设计,光环境设0lx,40lx,70lx,100lx四个水平,阅读媒介采用普通平板、滤蓝光平板和电子书三种。所有被试完成四种光环境实验,每种光环境持续三个晚上,被试在睡前(晚上9点到11点)使用电子设备进行阅读并完成随后的绩效任务,次日7点觉醒后完成后测。结果表明:1.阅读媒介主效应显著,对比其它两种媒介,使用电子书阅读对视觉疲劳和睡眠的影响最小,主观情绪评分与阅读绩效较高。2.光环境主效应显著,在40lx的光环境下,被试入睡时间最少,快速眼动阶段时间最长,并报告自己睡得更多,脑电显示更多的δ/θ波。在醒来时不仅感到更清醒,且能在更短的时间内达到完全清醒的状态,认知任务的表现更好,情绪更倾向积极;3.环境照度与电子媒介交互作用显著,对比其它环境等级,40lx光环境下使用普通平板阅读产生的视觉疲劳较少,主观情绪评分与阅读绩效较高。
Abstact: In the present study adopted two factors mixed designs and investigated the interaction of ambient light(0 lx, 40 lx, 70 lx, 100 lx) and reading medias(ipad、blue-light filtering ipad、ebook) on physical and psychological aspects, such as human sleep architecture, visual fatigue, mood and performance. The result showed that 1.using ebook woud induce less visual fatigue, higher sleep qualities and better performance in reading than using other medias. 2. Participants spent the least time to fall asleep, and had the longest duration of REM sleep, and rated themselves as less sleepy and their EEG showed more power within the delta/theta frequency range under the 40 lx ambient illumination. 3. Compared with other conditions, the use of Ipad under 40 lx ambient illumination caused the least visual fatigue, the scores on PANAS and reading performance were higher.
