1 You may need more sleep than you think.Research by Henry Ford Hospital Sleep Disorders Center found that people who slept eight hours and then claimed they were "well rested" actually performed better and were more alert if they slept another two hours. That figures. Until the invention of the lightbulb (damn you, Edison!), the average person slumbered 10 hoursa night.

　　1. 你需要的睡眠可能比你认为的要多。亨利福特医院睡眠紊乱中心的研究发现，睡了8个小时并声称得到了“很好的休息”的人们如果多睡两个小时，他们的表现实际上会更好，人也更机警。这很合理。一般人一晚上要睡十小时，直至灯泡被发明出来(爱迪生，你真该死!)。

　　2 Night owls are more creative. Artists, writers, and coders typically fire on all cylinders by crashing near dawn and awakening at the crack of noon. In one study, "evening people" almost universally slam-dunked a standardized creativity test. Their early-bird brethren struggled for passing scores.

　　2. 夜猫子更有创造力。艺术家、作家、程序员往往开足马力奋战至黎明，而后在中午时分才会醒来。在某项研究中，“晚睡人群”几乎普遍性地在标准化创造力考试中拔得头筹。而他们的早起同类却还在为了及格而挣扎。

　　3 Rising early is stressful. The stress hormone cortisolpeaks in your blood around 7 am. So if you get up then, you may experience tension. Grab some extra Zs! You’ll wake up feeling less like Bert, more like Ernie.

　　3. 早起是充满压力的。应激激素皮质醇在你血液中的含量于早上7时左右达到顶峰。所以如果你在那时起床，有可能会体验到紧张感。抓住那额外的一小会儿吧!你将会在起床时感觉更像乐观的Ernie，而不是厌世的Bert。
