     Do you feel a little sleepy after lunch? Well, that's normal. Your body naturally slows down then. What
should you do about it? Don't reach for a coffee! Instead, take a nap.
     There are many benefits (好处) of a daily nap. First of all, you are more efficient (有效率) after napping.
You remember things better and make fewer mistakes. Also, you can learn things more easily after taking a
nap. A 20-minute nap can reduce information overload. It can also reduce stress. Finally, a nap may increase
your self-confidence and make you more alert (灵活). It may even cheer you up.
     But, there are some simple rules you should follow about taking a nap. First, take a nap in the middle of
the day, about eight hours after you wake up. Otherwise, you may disturb your sleep-wake pattern. Next, a
20-minute nap is best. If you sleep longer, you may fall into a deep sleep. After waking from a deep sleep,
you will feel worse. Also, you should set an alarm clock. That way, you can fully relax during your nap.
You won't have to keep looking at the clock so that you don't oversleep.
     Now, the next time you feel sleepy after lunch, don't get stressed. Put your head down, close your eyes,
and have forty winks.
