An experiment was performed to clarify effects of intermittent daylight exposure in a resting-space on arousal level and task-performance in work place. Daylight flowing into the resting-space was controlled with window-blinds. Results indicated, 1) during two working sessions, 11:00-12:00 and 16:00-17:00, the arousal levels analyzed from the frequency of blink burst significantly decreases at the circadian condition more than the non-circadian condition. 2)At some working sessions of the circadian condition, the ratio of correct answer for “Arithmetic”, one of computer tasks, significantly decreases after the resting time more than the one before the resting time.
