Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies in their bodies. At that time---about eight hours after you wake up, your body temperature goes down. This is what makes slow down and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in experiments almost always followed a similar sleeping pattern(模式). They slept for one long period and then for one short period about eight hours later.

In many parts of the world, people take naps(小睡) in the middle of the day. This is especially true in warmer climates, where the heat makes work difficult in the early afternoon. Researchers are now saying that _____________ are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer less from heart disease.

Many working people, unluckily, have no time to take naps. Though doctors may advise taking naps, employers(雇主们) do not allow it! If you do have the chance, however, here are a few tips about making use of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep too long. If you do not have enough time, try a short nap--- even ten minutes sleep can be helpful.
