Are you sometimes a little tired in the early afternoon?   小题1:  . They may think it’s because we eat too much. Or, in summer, they may think it is too hot.   小题2:   . About eight hours after you wake up, your body temperature goes down.

In many parts of the world, people take naps(打盹) in the middle of the day. This is really true when it’s warmer, and the hot weather makes work difficult in the early afternoon. Now researchers are saying that naps are good for everyone at any time. 小题3:  If people often take naps, there are often few problems with their hearts.

小题4:  Though doctors may ask them to take naps, however, bosses don’t let them do it! If you do have the chance, 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. This can also happen if you sleep for too long. 小题5:,  try a short nap – even ten minutes of sleep can be helpful.
