Do you feel a little sleepy after lunch? Well, that’s normal (正常). Your body slows down then. What should you do about it? Don’t drink coffee! Instead, take a nap (打盹).

It’s good to have a daily nap. First of all, you are more energetic after napping. You remember things better and make fewer mistakes. Also, you can learn things more easily after taking a nap. A nap may improve your self-confidence (自信) and make you more active. It may even cheer you up. But, there are some rules you should think about taking a nap.

First, take a nap in the middle of day.

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 you don’t sleep too much.

Now, the next time you feel sleepy after lunch, don’t get stressed. Put your head down, close your eyes, and take a nap.

How do you remember the way to your house? Where do dreams come from?

It is your brain (大脑) that does these things. A British scientist showed that sleep can improve one’s memory. It’s not a dream for students to study when they sleep. In fact, your brain is working day and night. If you learn words before bed, a certain part of your brain may help you to remember the words while you sleep. What’s more, another scientist in the USA found that there was a “talent button(按钮)” in the human brain. It might make a person more talented(有才能的).

There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning(打哈欠)keeps your brain “cool”, which makes us think quicker.
