대면적광 광자극시 평가 시선에 따른 심박변이(HRV) 반응 연구

다국어 초록 (Multilingual Abstract)

In this study, each HRV (Heart Rate Variability) response was measured and compared under eyes-open and eyes-closed conditions after giant layered wall lightings (4000K, 100lx) were set. The results are as follows: Cardiovascular parameters by large area lighting (light wall) were all included in the standard range. VLF (Very Low Frequency) was stable when the HRV was higher than that of targets. The HRV was higher under eyes-closed condition than under eyes-open condition. With regard to body temperature control, vasomotion and hormone, a direct light projection method was stable under eyes-closed condition. LF (Low Frequency) was stable when the HRV was lower than that of targets. The HRV was lower under eyes-closed condition than under eyes-open condition. With regard to stress and supply of biological energy, a direct light projection method was stable under eyes-closed condition. In the case of HF (High Frequency), it was performed in a reversible state with regards to variations in respiratory cycle and heart rate variations. However, it was reduced and increased during eyes-open or eyes-closed conditions, respectively. Thus, the light stimulation by visual characteristics may be a factor affecting physiology. When lighting is given for the purpose of stress relief and stability, the lighting is more effective in non-visual environment. However, because the physiological efficacy is not limited in the Heart Rate Variability (HRV), it should be analyzed by various means such as Electroencephalogram (EEG) or electromyography (EMG).
