为何我再也无法在周末睡懒觉?

Waking up may feel instantaneous, but it’s actually a pretty gradual process. About an hour before you wake, your blood pressure and body temperature rise, as do levels of stress hormones like cortisol. Minute by minute, you become more alert until you’re completely awake. You can shut off your alarm clock, but your body clock will just keep ticking.

醒来或许感觉是瞬间发生的，但事实上这是个循序渐进的过程。在你醒来的一个小时前，你的血压和体温上升，同时还有压力荷尔蒙的水平，比如皮质醇。时间一点点过去，你越来越清醒直到彻底醒来。你可以关掉你的闹钟，但你的生物钟还会继续走着。

There’s another reason that you probably don’t want to think about: You’re just not as young as you used to be. We need less sleep as we get older. Babies need between 16 and 20 hours. Teenagers should (but often don’t) get nine hours a night. Younger and middle-aged adults need about eight hours of sleep a night. In general, the older you get, the harder it is to snooze the day away.

还有另一个你或许不愿意想的原因：你再也不像曾经那样年轻了。我们长大后所需的睡眠时间变少了。婴儿需要16到20个小时的睡眠。青少年应该每晚睡9个小时（但经常不能）。年轻和中年人需要大概8个小时的睡眠。总体来说，你年纪越大，睡得越少。Even if you do manage to sleep in, you may never fully catch up on your sleep. If your body needs eight hours every night and you only get six or seven from Monday to Friday, you’d have to sleep an extra five to ten hours on Saturday to make it up. And experts say even that may not be enough.
