青春期期间,“睡眠”激素——褪黑激素的释放有所延迟,这意味着青少年们往往直到晚上11点左右才会觉得昏昏欲睡。电子设备发出的蓝光会误导人的大脑,使其以为感觉到了干扰入睡的日光,在此刺激下,褪黑激素的释放进一步受到延缓,睡意就愈发姗姗来迟。明尼苏达大学的研究指出,88%的学生都在卧室里放有手机。
But many parents, and some students, object to shifting the start of the day later. They say doing so makes sports practices end late, jeopardizes student jobs, bites into time for homework and extracurricular activities, and upsets the morning routine for working parents and younger children.
不过许多家长以及一些学生都反对推迟上课时间。他们认为,这样体育锻炼就得拖到很晚才能结束,影响学生打工,侵占做家庭作业和从事课外活动的时间,还会扰乱需要工作的父母和年龄较小的孩子们早晨的时间安排。
At heart, though, experts say, the resistance is driven by skepticism about the primacy of sleep.
不过,专家表示,从本质上来说,会产生这种抗拒思维是因为他们对睡眠的重要意义持怀疑态度。
“It’s still a badge of honor to get five hours of sleep,” said Dr. Judith Owens, a sleep expert at the Children’s National Medical Center in Washington. “It supposedly means you’re working harder, and that’s a good thing. So there has to be a cultural shift around sleep.”
