Researchers say that there are a lot of advantages if we always get enough sleep. We can be smarter, thinner, healthier and more cheerful. Also we’re to have better skin, better memories and longer lives.

In general, adults are thought to need at least eight hours of sleep a night, but a recent survey found that, on workdays, only 21% of them really get a full eight hours of sleep, and another 21% get less than six. For teenagers, a healthy amount is about eight to nine hours every night. However, about 80% of high school students don’t get enough sleep because of their schoolwork or some bad habits.
