摘要

虽然太阳光中的近红外辐射(NIR)和可见光的含量大致相同,但目前大多数电力照明系统中都没有近红外辐射,而且节能窗户也会过滤近红外辐射。然而,近红外具有生物活性,通常用于对一系列认知、情绪和身体状况进行有针对性的光生物调节治疗。鉴于近红外已从室内照明中去除,因此了解环境中的近红外如何影响心理和生理健康,以及室内环境中近红外暴露减少是否会引起人们的关注至关重要。在一项预先登记的受试者内双盲实验中,151 名大学生(117 名女性,34 名男性)样本研究了环境照明中近红外和远红外波长对认知、情绪状态和心血管健康的急性影响。在为期 2 小时的实验室课程中,参与者在两种平衡照明条件下分别接受了静态和认知任务的监测。两种照明条件都包括由发光二极管(LED)系统产生的 3500 K 白光,其中一种照明条件还包括峰值波长为近红外(875 nm、960 nm)和远红外(735 nm)光谱的 LED。在环境照明中添加近红外和远红外对静息高频心率变异性(HF-HRV)、HF-HRV 对认知需求的反应以及愉悦感都有好处,但会降低视觉搜索任务的表现。这些研究结果表明,建筑照明中缺少近红外会在心理和生理层面影响人类,对健康和幸福产生影响,需要与节能考虑因素相平衡。

Effects of near-infrared radiation in ambient lighting on cognitive performance, emotion, and heart rate variability
Although sunlight contains approximately equal amounts of near-infrared radiation (NIR) and visible light, NIR is absent from most present-day electric lighting systems and is filtered by energy-efficient windows. However, NIR is biologically active and is commonly applied in targeted photobiomodulation treatments for a range of cognitive, emotional, and physical conditions. Given the removal of NIR from indoor illumination, it is critical to understand how ambient NIR may influence psychological and physical health, and whether reduced exposure to NIR in indoor environments could because for concern. In a preregistered within-subjects double-blind experiment, acute effects of NIR and far-red wavelengths in ambient illumination on cognition, emotional state and cardiovascular health were examined in a sample of 151 university students (117 females, 34 males). During a 2-h laboratory session, participants were monitored at rest and while engaged in cognitively demanding tasks across two counterbalanced lighting conditions. Both included 3500 K white light generated by a light-emitting diode (LED) system, while one additionally included LEDs with peak wavelengths in the NIR (875 nm, 960 nm) and far-red (735 nm) spectrum. The addition of NIR and far-red to the ambient lighting showed beneficial effects on resting high-frequency heart rate variability (HF-HRV), HF-HRV responses to cognitive demand, and feelings of pleasure, but reduced performance on a visual search task. These findings reveal that the absence of NIR from architectural lighting influences humans at a psychological and physiological level, with implications for health and well-being that need to be balanced with energy-saving considerations.

期刊介绍: The Journal of Environmental Psychology is the premier journal in the field, serving individuals in a wide range of disciplines who have an interest in the scientific study of the transactions and interrelationships between people and their surroundings (including built, social, natural and virtual environments, the use and abuse of nature and natural resources, and sustainability-related behavior). The journal publishes internationally contributed empirical studies and reviews of research on these topics that advance new insights. As an important forum for the field, the journal publishes some of the most influential papers in the discipline that reflect the scientific development of environmental psychology. Contributions on theoretical, methodological, and practical aspects of all human-environment interactions are welcome, along with innovative or interdisciplinary approaches that have a psychological emphasis. Research areas include: •Psychological and behavioral aspects of people and nature •Cognitive mapping, spatial cognition and wayfinding •Ecological consequences of human actions •Theories of place, place attachment, and place identity •Environmental risks and hazards: perception, behavior, and management •Perception and evaluation of buildings and natural landscapes •Effects of physical and natural settings on human cognition and health •Theories of proenvironmental behavior, norms, attitudes, and personality •Psychology of sustainability and climate change •Psychological aspects of resource management and crises •Social use of space: crowding, privacy, territoriality, personal space •Design of, and experiences related to, the physical aspects of workplaces, schools, residences, public buildings and public space
