最近，人们越来越多地意识到暴露在日光下和风景下对健康的好处。日光暴露与昼夜节律调节有关，这可能会对睡眠质量和认知功能产生重大影响。对自然的看法也被证明会影响情绪和表现。本研究探讨了优化的日光和景观对上班族睡眠和认知表现的影响。30名知识工作者在两个布局、家具和朝向相同的办公室环境中各工作了一周；然而，其中一个配备了电致变色玻璃，另一个配备了传统的百叶窗，分别产生了相当于40.6勒克斯和316勒克斯的黑视光线条件。根据手腕活动记录仪的测量，在优化的日光和视野条件下，参与者的睡眠时间延长了37分钟，在旨在测试他们更高级别决策能力的认知模拟中得分高出42%。在太空中呆了一天后，睡眠和认知功能都会受到影响，但随着时间的推移，这种影响会变得更加明显。对于几乎所有的参与者来说，优化的日光和视野对认知功能的积极影响是相似的，而对于那些基线睡眠时间最短的人来说，睡眠时间的增加明显更大。这项研究强调了日光设计的重要性，以优化上班族的睡眠质量和表现。
A growing awareness has recently emerged on the health benefits of exposure to daylight and views. Daylight exposure is linked to circadian rhythm regulation, which can have significant impacts on sleep quality and cognitive function. Views of nature have also been shown to impact emotional affect and performance. This study explores the impact of optimized daylight and views on the sleep and cognitive performance of office workers. Thirty knowledge workers spent one week working in each of two office environments with identical layouts, furnishings, and orientations; however, one was outfitted with electrochromic glass and the other with traditional blinds, producing lighting conditions of 40.6 and 316 equivalent melanopic lux, respectively. Participants in the optimized daylight and views condition slept 37 min longer as measured by wrist-worn actigraphs and scored 42% higher on cognitive simulations designed to test their higher order decision-making performance. Both sleep and cognitive function were impacted after one day in the space, yet the impacts became more significant over the course of the week. The positive effect of optimized daylight and views on cognitive function was comparable for almost all participants, while increases in sleep duration were significantly greater for those with the lowest baseline sleep duration. This study stresses the significance of designing with daylight in order to optimize the sleep quality and performance of office workers.
