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.
你觉得早上起床很难，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，他证明了每个人都有一个每日的能量循环。
During the hours when you labor through your work you may say that you're "hot". That's true. The time of day when you feel the 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 John talks to himself: "Get up, John! You'll be late for work again!"The possible explanation for the trouble is that John 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.
在你工作的时候，你可能会说你很有“活力”。这是真的。一天中你感觉最有活力的时候是你的体温周期达到顶峰的时候。对一些人来说，高峰出现在上午。对另一些人来说，高峰出现在下午或晚上。没有人知道为什么会这样，但这导致了熟悉的独白，如约翰自言自语：“起来，约翰！你上班又要迟到了！”麻烦的可能解释是，约翰在晚上处于他的温度和精力高峰。很多家庭争吵结束时丈夫和妻子意识到这些能量周期意味着什么，以及每个家庭成员都有哪些能量周期。
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. Adjust your cycle to some extent by 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 usual hour. This won't change your cycle, but you'll get up steam and work better at your low point.
你不能改变你的能量周期，但你可以学会让你的生活更好地适应它。克莱特曼博士认为，习惯可以帮助你。也许你晚上很困，但觉得无论如何你必须熬夜。通过熬夜来调整你的能量循环，在一定程度上比你想的晚。如果你早上能量不足，但你有一项重要的工作要做，比你通常早起床一小时。这不会改变你的周期，但你会在你的低谷时变得更有活力，工作得更好。
Begin with a slow start which saves your energy. Get up with a slow 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 usual work in the afternoon and spend time doing important work for your high peak hours.
慢慢开始，这样可以节省你的精力。慢慢地打个哈欠，舒展筋骨。在把脚落在地板上之前，先床边坐一分钟。前一天晚上找到干净的衣服，把它们放好，避免寻找的麻烦。只要可能，在下午做普通的工作，并花时间在高峰时段做重要的工作。
