If you equate getting older with needing—or getting—less sleep, here’s a wake-up call: It's not true! “The majority of us require between seven and nine hours of shut-eye a night," says Robert Oexman, D.C., director of the Sleep to Live Institute. “And there’s little reason—whether you’re 55 or 80—not to get it.” Barring disease, medication and pain (all legitimate sleep interrupters), if patients complain of bad sleep, Dr. Oexman looks at their nighttime habits, where the problem almost always resides. 如果你认为人慢慢长大变老，需要或得到的睡眠更少，那我来提醒你吧，不是这样的！睡眠与生命研究所所长，脊骨神经科医师罗伯特·欧克斯曼说道：“大多数人每晚需要7-9小时的睡眠时间。无论你是55还是80岁，都应该做到这一点。”疾病、药物和疼痛除外（这些都可能会干扰睡眠），如果病人抱怨睡不好觉，欧克斯曼医师会查看其晚间生活习惯来发现问题所在。 So, how are you sabotaging your z-z-z-z-z’s? 所以，你是怎样破坏自己的睡眠的呢？ Bad Habit #1: Watching TV until you fall asleep
坏习惯一：看电视看到睡着 Why It Disrupts Sleep: It has nothing to do with what you watch—Downton Abbey isn’t a better pre-sleep choice than Dog the Bounty Hunter. Rather it’s the exposure to TV’s bright light that’s the culprit. Artificial bright light after dusk not only enhances alertness, but also delays the production of melatonin, a sleep-inducing hormone. So even if you nod off (in front of the TV, for example), you probably won’t stay asleep for long. |
