通过周末睡懒觉来补眠不可行

　　"The sleep restriction was severe enough that recovery of alertness was not complete following a single night of extended sleep," said study researcher David Dinges, of the University of Pennsylvania School of Medicine. "Lifestyles that involve chronic sleep restriction during the workweek and during days off work may result in continuing buildup of sleep pressure and in an increased likelihood of loss of alertness and increased errors."

　　“睡眠不足非常严重，一个晚上的懒觉不足以让人的头脑灵敏度恢复，”宾夕法尼亚大学医学院研究院大卫-迪金斯说道。“周一到周五乃至非工作时间长期缺觉的生活方式会导致睡眠压力的持续累积，使得灵敏度降低和频频犯错误的可能性增加。”
