Abstract

Several studies have examined lighting in workplace environments, however little research has focused on how different correlated color temperatures (CCT) affect stress reduction. This study aims to identify the most effective lighting condition for stress recovery by comparing the stress-reducing effects of 4000K and 6000K CCTs utilizing Neuroarchitecture principles. By understanding how different elements of a built environment affect the human brain, neuroarchitecture aims to create more effective, harmonious, and human-centered spaces.

An experiment was conducted with 36 participants (aged 19 to 26, mean age 22.5), who completed a stressful memory task before being exposed to a virtual workplace environment under both lighting conditions. The recovery process was repeated for each CCT, and heart rate responses—measured via pulse oximeter while participants wore a virtual reality (VR) headset—were used as an objective stress indicator. A post-experiment survey evaluated subjective preferences.

Results indicated that both lighting conditions reduced stress, but the 6000K environment offered a slight advantage in promoting relaxation. Additionally, 80.5% of participants reported feeling less stressed under the 6000K condition, although 50% showed a discrepancy between their subjective preferences and heart rate data. This study provides valuable insights for workplace design, emphasizing the role of lighting in supporting employees’ well-being.

照明对减压的影响：利用神经建筑学原理研究工作场所设计中的相关色温

一些研究已经检查了工作环境中的照明，但是很少有研究关注不同相关色温（CCT）如何影响减压。本研究旨在利用神经建筑学原理，通过比较4000K和6000K cct的减压效果，确定最有效的应激恢复照明条件。通过了解建筑环境的不同元素如何影响人类大脑，神经建筑旨在创造更有效、和谐和以人为本的空间。研究人员对36名参与者（年龄在19至26岁之间，平均年龄22.5岁）进行了一项实验，他们在两种照明条件下的虚拟工作环境中完成了一项压力记忆任务。每个CCT都重复恢复过程，并且心率反应-当参与者戴着虚拟现实（VR）耳机时通过脉搏血氧仪测量-被用作客观的压力指标。实验后的调查评估了主观偏好。结果表明，两种照明条件都能减轻压力，但6000K的环境在促进放松方面有轻微的优势。此外，80.5%的参与者报告说，在6000K的条件下，他们的压力减轻了，尽管50%的人表现出他们的主观偏好和心率数据之间的差异。本研究为工作场所设计提供了有价值的见解，强调了照明在支持员工幸福感方面的作用。
