High school students are reported to be excessively sleepy, resulting in decreased academic performance, increased psycho-social problems and increased risk of morbidity and mortality from accidents. Early school start times have been noted to contribute to this problem. This report attempts to confirm the relationship of early school start times with decreased sleep and increased sleepiness.
We examined sophomore and junior students in 2 local high schools with different start times and measured the amount of time slept and sleepiness.
We found that students at the early start school reported reduced sleep time and more sleepiness than their counterparts at the later starting school.
Early school start times are associated with student reports of less sleep and increased sleepiness. Further studies in larger groups are recommended in view of the potential significant impact of sleep deprivation in this age group.
据报道，高中生过度困倦，导致学业成绩下降、心理社会问题增多以及事故导致的发病和死亡风险增加。人们已经注意到过早的上学时间促成了这一问题。本报告试图证实过早的上学时间与睡眠减少和困倦增加之间的关系。
我们对两所当地高中不同上学时间的高二和高三学生进行了检查，并测量了睡眠时间和困倦程度。
我们发现，早上学的学校的学生报告的睡眠时间比晚上学的学校的学生少，且更困倦。
过早的上学时间与学生报告的睡眠减少和困倦增加有关。鉴于睡眠剥夺对该年龄组可能产生重大影响，建议对更大规模的群体进行进一步研究。
