Maintaining adequate sleep is the single best thing a person can do to improve their health. People lacking sleep can suffer from listlessness the next day. If we don’t get enough sleep, our immune systems will be compromised. In other words, we may become susceptible to certain diseases as a result of a weakened immune system. Nowadays more and more people, especially grownups, like to stay up late. Some of them play computer games while others enjoy nightlife. They don’t know how harmful it is to stay up late and not get enough sleep. A good, sound sleep makes people refreshed and energetic all day. When our bodies and organs got enough rest, they work well the next day. It’s kind of like maintenance for a machine; it can extend its lifespan. So I hope people realize how important good sleep is and keep good sleep habit from now on.
