When it comes to sleep, peoples opinions vary. Some people think that we should sleep as much as possible to keep our mind conscious. Some people think that we shouldnt sleep too much because long time sleep makes people sleepy. In my opinion, appropriate sleep can not only refresh our mind but also keep us energetic.

First of all, enough sleep makes us energetic. After a days working, people feel tired. Therefore, a good and enough sleep can help people recover from the exhausting status.

Secondly, sleep enough can avoid illness. It is investigated that more than 90% people who suffers from insomnia are tending to fall ill easily compared with those who have enough sleep.

Thirdly, enough sleep benefits our mind. According to researcher from American and French, the “Sharp Wave Ripple” in brain which is responsible for strengthen memory can only appear when people fall into deep sleep. If we have enough sleep, then our memory will be improved so that we can learn things more efficiently.

All in all, enough sleep makes us energetic, benefit our mind and also help us to avoid from being ill. Hence, people should get enough sleep.
