| Outline of Final Research Achievements |
The purpose of the present study was to determine the relationships among daily rhythms, health-related quality of life, and evening lifestyle. The findings of the current study led to the establishment of “Health promotion guidelines based on circadian rhythms." Elements of evening lifestyle, such as timing of dinner, or exercise may delay the daily rhythm, possibly exacerbating sleep latency. Thus, evening lifestyle may act as an entraining agent of circadian rhythm. In addition, we observed a significant relationship between chronotype and mental component summary score.
