Recently Dr. Cleiman 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 is true, the time of day when you feel most energetic
(full of energy) is when your cycle of body temperature is at its peak(top). For some people the peak comes
during the forenoon (上午前). For others it comes in the afternoon or evening. No one has discovered why
this is so.
Much family quarrelling ends when husbands and wives realize what this energy cycle means and which
cycle each member of the family has.
You cannot change your cycle, but you can learn to make your life fit it better."Habits can help," Dr.
Cleiman believes. If your energy cycle is low in the morning but you have an important job early in the day,
rise before your usual hour, and then you will work better at your low point.
Get off to a slow start which saves your energy. Get up with a lazy yawn (哈欠) and stretch. Sit on the
edge of bed before putting your feet on the floor. Avoid the troublesome searching for clean clothes by laying
them out the night before.
