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 hours a night.

    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.

    3. Rising early is stressful.

    The stress hormone cortisol peaks 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.

    1、 你需要的睡眠时间也许比你想象的要久。

    “亨利·福特医院睡眠疾病研究中心”的研究表明，那些在8小时睡眠后声称自己“休息得很好”的人，如果再让他们睡两个小时，实际上会表现得更好而且更加有精神。这一点貌似是有道理的。在电灯发明以前（该死的爱迪生），人们每晚的平均睡眠时间通常是10小时。

    2、 夜猫子更富创造力。

    艺术家、作家和编程人员是典型的“日落而作，日出而息”。他们在夜间精神抖擞，眼放精光，而不到日上三竿不会起来。在一项研究中，夜猫子几乎都很easy地高分通过了标准化创造能力测试（英文版，中文版），而那些信奉“早起的鸟儿有食吃”的老兄们则在及格线上挣扎。

    ３、早起让你倍感压力。

    早上７点左右你血液中的压力荷尔蒙皮质醇含量达到最高。所以如果在那时起来，你会感到心绪紧张。再倒头睡个回笼觉吧！这样你起来的时候将更像一个孙悟空，而不是猪八戒：）
