Sleep is very important. I read that a teenager should sleep for eight or nine hours a night. Many of my classmates only get a few hours' sleep. Some say that going to bed early is a waste of time or they don't have enough time for their homework. They need better time management, like spending less time hanging around with friends after school. Lack of sleep leads to many problems. My brain doesn't function as well, and I also get depressed and easily annoyed when I'm tired. I always go to sleep before 11pm, even when I have a test the next day. I would rather be having a nice dream than worrying about a test! JUSTINE CHAU WING-YIN SKH Lam Kau Mow Secondary School Thanks for your letter in praise of sleep, Justine. I too am a big fan of sleep and can't function if I don't get my eight hours. If you want to go to bed earlier, but can't seem to fall asleep, there are a number of things you can do. Exercising during the day almost always guarantees a good night's sleep for me. Also avoid coffee or soft drinks, as the caffeine will keep you awake. Having a bedtime routine makes for a good night's rest. Also avoid watching TV just before you go to bed, as your mind will still be active. Kate, Editor
