　　Do you find it very difficult and painful to get up in the morning?This might be called laziness,but Dr.Kleitman has a new explanation.He has proved that everyone has a daily energy cycle.
　　During the hours when your labor through your work you may say that you’re“hot”.That’s true.The time of day when you feel most energetic is when your cycle of body temperature is at its peak.For some people the peak comes during the forenoon.For others it comes in the afternoon or evening.No one has discovered why this is so,but it leads to such familiar monologues as:“Get up,Peter!You’ll be late for work again!”The possible explanation to the trouble is that Peter is at his temperature-and-energy peak in the evening.Much family quarrelling ends when husbands and wives realize what these energy cycles mean,and which cycle each member of the family has.
　　You can’t change your energy cycle,but you can learn to make your life fit if better.Habit can help,Dr.Kleitman believes.Maybe you’re sleepy in the evening but feel you must stay up late anyway.Counteract your cycle to some extent by habitually staying up later than you want to.If your energy is low in the morning,but you have an important to do early in the day,rise before your usual hour.This won’t change your cycle,but you’ll get up steam and work better at your low point.
　　Get off to a slow start which saves your energy.Get up with a leisurely yawn and stretch.Sit on the edge of the bed a minute before putting your feet on the floor.Avoid the troublesome search for clean clothes by laying them out the night before.Whenever possible,do routine work in the afternoon and save requiring more energy or concentration for your sharper hours.

　　参考译文：
　　你觉得早上起来很困难很痛苦吗？这可能被称为懒惰，但克莱特曼博士有一个新的解释。他证明了每个人每天都有一个能量循环。
　　在你工作的时间里，你可能会说你很“热”。那是真的。一天中，当你感到最有活力的时候，就是你的体温循环达到顶峰的时候。对一些人来说，高峰是在上午。对其他人来说，是在下午或晚上。没有人发现这是为什么，但它导致了如此熟悉的独白：“起来，彼得！你又要迟到了！“问题的可能解释是，彼得在晚上的温度和能量达到了顶峰。当丈夫和妻子意识到这些能量循环意味着什么，以及每个家庭成员的能量循环时，许多家庭争吵就结束了。
　　你不能改变你的能量循环，但你可以学会让你的生活变得更好。克莱特曼博士相信，习惯可以帮助我们。也许你晚上很困，但还是觉得你必须晚睡。在某种程度上，通过习惯性地晚睡来抵消你的周期。如果你早上精力不足，但是你有重要的事情要做，那就在平常的时间之前起床。这不会改变你的周期，但你会振作起来，在最低点工作得更好。
　　起步慢，省力。站起来，悠闲地打个呵欠，舒展筋骨。坐在床边一分钟，然后把脚放在地板上。避免麻烦的寻找干净的衣服，把它们放在前天晚上。只要有可能，在下午做一些日常工作，这样可以节省更多的精力或精力，让你的工作更轻松。
