Abstract

Although it has been known that brief nap after lunch could eliminate the sleepiness and improve intellectual concentration, the effect has not been evaluated quantitatively. In this study, an evaluation experiment was conducted in three days to investigate the effect of brief nap on intellectual concentration quantitatively. The first day was preparatory day to be accustomed experimental procedure and the cognitive task. The second and the third days were measurement with/without the brief nap, where the order was counterbalanced for each participant groups. The degree of intellectual concentration was measured by using the CTR (Concentration Time Ratio), and those of the second and third day were compared. During the experiment, the questionnaires for subjective fatigue, sleepiness, and motivation were performed, and CFF was also measured to verify their brain fatigue. As the result, it was confirmed that subjective sleepiness and fatigue was significantly reduced and improvement of CTR was marginally significant on the day with a brief nap.
