| Research Abstract |
The purpose of this study was to investigate the annual variations of melatonin secretion of subjects and of their surrounding light conditions in Japan and Sweden. Swedish subjects got a lot of light in evening and nighttime due to long-day in summer. The annual light change in Japan was small in comparison with Sweden. The melatonin peak level decreased and the peak time advanced in summer, while in winter the peak level increased and the peak time delayed in Japan. The melatonin secretion in Sweden was lower than in Japan during the course of a year.
