Growing up, I have read some news about sleeping. Now I have found their connections after I recalled them. In short, plenty sleep makes you smart, lacking sleep will damage your brain.

In my mind, the first news about sleep that I read was: short sleepers are more energetic, while long sleepers are good at deep thinking. I forget the news source, but I find a similar artical. The following link is English version:
http://books.google.com.hk/books?id=V8Sas74bBjwC&pg=PA27&lpg=PA27&dq=hartman+sleep+Einstein&source=bl&ots=M4mQ65W5y_&sig=ITqgcJzra3yGK8RAWSGZegswTZo&hl=en&sa=X&ei=EJ9NU4e-BojmiAfD8ICoAQ&ved=0CFIQ6AEwCA#v=onepage&q=hartman%20sleep%20Einstein&f=false
里面提到长睡者里面多会出现思想家和创造性脑力劳动者，比如爱因斯坦。
This atrical mensioned that very creative, concered persons both in art and in science often are long sleepers, like Einstein.
去年又看到文章说睡眠能补充脑细胞：

Last year, I saw a piece of news that reads Sleep ‘boosts brain cell numbers’
http://www.bbc.com/news/health-23932577
这样就解释了为什么爱因斯坦这么聪明的人是个长睡者了(^_^)
That’s why Einstein is so clever!
后来又看到《睡眠不足6小时会导致700个基因活动改变》

Then I saw an atrical says “a lack of sleep affects the activity of more than 700 of our genes”

这个月又看到一篇研究结果，说《研究称缺少睡眠会对大脑造成永久性损伤》。实验只研究了老鼠，不过估计人类也差不多。

This month, I saw an research result, it says “Sleep loss may cause brain damage”. Although researchers only did this experiment on mice, but maybe it also works on human beings.

通过将这些新闻进行联系，我们已经清楚知晓，睡觉对人体有无可替代的作用，每天最好保证8小时高质量的睡眠。关于如何提高睡眠质量，可以看我总结的这篇文章：

所以，为了有个健康聪明的大脑，大家赶紧睡觉吧！
So, in order to have a healthy and smart brain, everybody go to sleep!
