　　Passage 2

　　Do you find getting up in the morning so difficult that it, spainful This might be called 1aziness, but Dr. kleitman has a new explanation. He has proved that everyone has a daily energy cycle.

　　During the hours when you labour through your work you may say that yourehot. Thats 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 1eads to such familiar monologues as: Get up, John! Youll be late for work again! The possible explanation to 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.

　　You cant change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. K1eitman believes. Maybe youre 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 wont change your cycle, but youll get up steam and work better at your low point.
