Do you find getting up in the morning so difficult that it's painful 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 you labor through your work you may say that you are "hot". That's true. The time of day when you feel most energetic (精力充沛的)is when your cycle of body temperature is at this peak (高峰). For some people the peak comes during the morning. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar words as: "Get up, John! You'll be late for work again!" The possible explanation to the trouble is he 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 it better. Habit can help, Dr. Kleitman believes. Maybe you're sleepy in the evening but feel you must stay up late anyway. Counteract (对抗)your cycle to some extent by habitually (习惯性地)staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day, rise before your usually 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 (呵欠)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 tasks requiring more energy for your sharper hours.

A. Energy cycle and body temperature are the same things.

D. If you rise earlier than usual, you will be more efficient at your low point in the morning.

你是否发现在早晨起床很难，是不是感到很痛苦？这种现象可以称之为“懒惰”。但是凯尔特曼博士对此有另外一种解释。他已证明每个人都有一个日常能量周期。

当你长时间的干体力活时，你可能会说你很“热”，那很正常。一天当中你感到你最精力充沛的时候是你的体温周期达到这个“热”的高峰期的时候。有些人的高峰期是在早晨，而有些人是在下午或晚上。当我们听到这样熟悉的话—“起床了，约翰！你上班又要迟到了！”还没有人能解释事情的原因。问题可能的解释是他的体温和能量周期是在晚上。在很多家庭里，丈夫和妻子由于不明白什么是能量周期，而且不明白家庭每一个成员的周期是怎样而争吵。

你不能改变你的能量周期，但是你可以了解它，以便更好地使你的生活适应它。凯尔特曼博士认为：习惯才能有帮助。可能你在晚上的时候感到昏昏欲睡，但你却无论如何要在晚上熬夜。性惯性的熬到比你想睡觉的时候晚些，这样在某种程度上可以和你的周期对抗。如果早晨你的能量低，但是你在白天还有很重要的工作要做，那么你可以在比你通常起床的时间早一些的时候起床。这不能改变你的周期，但这样你可以有精力，而且在你低能量的时候可以工作的更好一些。

慢慢开始起床，这样可以节省你的能量。悠闲地打个呵欠，伸伸懒腰。在你脚粘地以前在床边做上一分钟。尽量避免寻找你昨晚准备穿的干净衣服。如果可能，在下午的时候做那些平淡的日常工作，把那些需要更多能量的工作流到你能量高峰期的时候做。
