	Abstract

This paper examines the psychological and psychophysiological effects of blue light exposure – as compared to red light exposure – on older adults during the day. The blue lighting was found to be significantly more activating and more unpleasant than the red lighting. The mid-frequency high-frequency ratio of the heart period variability slightly decreased under blue lighting indicating an increase of parasympathetic modulation in this lighting condition compared to red lighting.
