| Outline of Final Research Achievements |
Why a short daytime nap of about 15 minute, which is composed of sleep stage 1 and 2, has recuperative power? It is already clarified that sleep stage 2 had recuperative effects, while these effects were limited following only sleep stage 1. Then EEGs during sleep stage 2 was investigated in the present study. The results showed that both theta waves and sleep spindles contribute to the recuperative power of a short daytime nap.
