Attention has been focused on human adaptability to human-adopted artificially modern and comfortable environments which may not always match the adaptability by the physiological state of humans. This discrepancy was found to induce a slight tension in the human body on evaluation with a physio-anthropological approach. Although a standard methodological approach has yet to be established, the present study attempted to evaluate human adaptability to artificial light environment, based on evaluations from three major possible perspectives: a) central nervous system, b) autonomic nervous system and c) biological rhythm. In order to detect the slight tension, human volunteers were exposed to an artificial light environment, and the appropriate physiological parameters were then examined from photic signal pathways in a brain. The findings revealed that a higher color temperature of fluorescent lamps induced a slight tension, although many other factors remained to be elucidated.
