![]() ![]() The pandemic acted as an environmental factor that caused stress. Additionally, those working in the medical sector have particularly high stress levels. Nevertheless, South Koreans are under more stress than people in Japan, China, the United States, the United Kingdom, and Germany. Korea is also recognized as an exemplary case in slowing the pace of the pandemic without enforcing regional lockdowns due to the active response and strict personal hygiene rules introduced by the government following the outbreak of COVID-19.

Korea has excellent public health facilities, with more hospital beds and medical equipment than the Organisation for Economic Co-operation and Development (OECD) average. As chroma increased under low-value conditions, color is a stress factor for men, this effect was more evident in the blue hue. 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. ln(LF) decreased as chroma increased under blue hue and high-value conditions in males. 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. The effect of chroma on the HRV of males and females was verified, but the interaction effect between chroma and gender was not. ![]() 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. This study investigated how changing environmental color chroma affected heart rate variability (HRV) and stress. Environmental color stimulates human vision and affects stress levels. ![]() Compatible with iPhone, iPad, and iPod touch.With increasing time spent indoors during the coronavirus disease pandemic, occupants are increasingly affected by indoor space environmental factors. next song, pause / play, light on/off, or random color)!
