Getting up early

Do you find getting up early in the morning so difficulf that it's painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proven 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 ture. 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 it is so, but it leads to such familiar monologues as:"Get up, John! You'll 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 whe husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.
