With increasing time spent indoors during the coronavirus disease pandemic, occupants are increasingly affected by indoor space environmental factors. Environmental color stimulates human vision and affects stress levels. This study investigated how changing environmental color chroma affected heart rate variability (HRV) and stress. The HRV of nine males and fifteen females was measured during exposure to 12 color stimuli with changes in chroma under green/blue hues and high/low-value conditions, and a stress assessment was performed. The effect of chroma on the HRV of males and females was verified, but the interaction effect between chroma and gender was not. ln(LF) and RMSSD were valid parameters. ln(LF) of males and females decreased as chroma increased under the green hue and low-value conditions; RMSSD was reduced as chroma increased in the blue hue and low-value conditions. ln(LF) decreased as chroma increased under blue hue and high-value conditions in males. Color-stress evaluation revealed that the higher chroma under high-value conditions, the more positive the stress emotion, and the lower the chroma under low-value conditions, the more negative the stress emotion. As chroma increased under low-value conditions, color is a stress factor; for men, this effect was more evident in the blue hue.
随着在冠状病毒病大流行期间室内时间的增加，居住者越来越受到室内空间环境因素的影响。环境颜色刺激人类视觉并影响压力水平。本研究调查了环境颜色色度的变化如何影响心率变异性 (HRV) 和压力。在暴露于 12 种颜色刺激下，测量了 9 名男性和 15 名女性的 HRV，这些刺激的色度发生了变化，并且在绿色/蓝色色调和高/低值条件下进行了压力评估。验证了色度对男性和女性 HRV 的影响，但色度和性别之间没有交互作用。ln(LF)和 RMSSD 是有效的参数。在绿色色调和低值条件下，男性和女性的 ln(LF)随着色度的增加而降低；在蓝色色调和低值条件下，RMSSD 随着色度的增加而降低。在蓝色色调和高值条件下，男性的 ln(LF)随着色度的增加而降低。颜色压力评估显示，在高值条件下色度越高，压力情绪越积极，在低值条件下色度越低，压力情绪越消极。在低值条件下，颜色随着色度的增加而增加，是一个压力因素；对于男性，这种影响在蓝色色调下更为明显。
