     Do you often feel a little sleepy after lunch? Well, that's normal. Your body naturally lays down. What

should you do about it? Don't drink coffee, take a nap (打盹), instead. There are many advantages of a

daily nap. First of all, you can remember things better and make fewer mistakes. Also, you can learn things

more easily after taking a nap. A 20-minute nap can reduce (减少) your pressure (压力). Finally, a nap can

make you cheerful.

     But there are some simple rules that you should follow about taking a nap. You should take up at noon,

about eight hours after you wake up. In general, a 20-minute nap is the best. If you sleep longer, you may

fall into a deep sleep. After waking up, you'll feel worse. Also, you should set an alarm clock. That way,

you can feel fully relaxed during the nap. You don't have to go looking at the clock so that you don't oversleep

(睡过头).
