研究了日本初中生（415名女孩和411名男孩;年龄范围，12-15岁）白天光照条件对睡眠习惯和早晚偏好的影响。在课间休息或午休时间在户外的学生比留在室内的学生更喜欢早晨型。与不遮光的学生相比，遮光的学生主观睡眠潜伏期更长，睡眠更浅。根据日本年轻学生的昼夜节律系统，阳光可能是睡眠时间的重要因素。
The effect of daytime light conditions on the sleep habits and morning-evening preference of Japanese junior high school students (415 girls and 411 boys; age range, 12-15 years old) was studied. Students who were outdoors during the short break between classes or their lunch-time break were more morning-type people than those who remained indoors. Students who shut out the light from outside showed longer subjective sleep latency and appealed more shallow sleep rather than those who did not. Sunlight can be an important factor for the timing of sleep based on the circadian system of Japanese young students.
