there is really nothing seriously wrong with you, physically that is. The analyst' s report shows that basically you are very fit.

W: So, why is it that I' m always so nervous... tense... ready to jump on anybody-my husband, children, and colleagues？ M: I think your condition has a lot to do with your habits.

W: Habits？

M: Yes... now tell me, madam, you smoke, don't you？

W: Yes, I'm afraid I do, doctor.

M: And, very heavily, I imagine.

W: Yes, quite heavily.

M: What do you eat normally？

W: I' m a good eater. Yes, I' d say I'm a good eater. But usually, I don't eat breakfast.

M: That' s bad for your health. I think you should get up early and have breakfast. And, another question, do you get up early？

W: No, I usually get up at 9: 00 a. m. I get up late because I go to bed too late. I stay up late watching TV till the midnight.

M: What sport do you usually do？

W: I don't like sports. But sometimes I play cards with some friends, that may be my sport.

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 is when your cycle of body temperature is at this peak.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 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 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.

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 tasks requiring more energy for your sharper hours.
