It’s nearly noon on a Saturday and you can’t believe it: your teenager is still in bed, sleeping away. But before you wake him up---mumbling to yourself that you can’t believe what a lazybones he is---you should know that he probably needs all the zzzs he can get.
As much as nine hours of sleep a night, in fact. Furthermore, teens’ circadian rhythms (i.e., processes that occur once a day) mean that young people would rather stay up past midnight and rise after 9 a.m. The result? Many teens stay up late, drag themselves out of bed early for school and try to make up the sleep debt on the weekends---or in class!
“There’s a biological reason why teens stay up late and want to sleep late,” says Dr. Stan Kutcher, the Sun Life Chair of Adolescent Mental Health at Dalhousie University in Halifax. “Their natural sleep-wake cycle changes as part of the maturation process. And because of changes in their social activities, recovering from sleep debt is more problematic.”
Teens need extra sleep for several reasons. First, their brains are changing. “The brain is reorganizing itself, laying down new pathways. What we’re seeing is a relationship between brain redevelopment and an increased need for sleep,” says Kutcher. As well, growth hormones are released during sleep, so adequate sleep is crucial for adolescents’ physical development. In addition, everything adolescents have learned in school that day is being processed and locked into long-term memory during sleep. Sufficient sleep also plays a key role in overall physical health. The immune system, for example, needs deep sleep to become and remain robust(healthy).
Staying up late on school nights means that, on average, teens get between six and a half and seven hours of sleep a night---about two hours less than they need. As a result, many either doze off in class or have trouble concentrating. Some of the behavioural problems and irritability in teens can be linked directly to sleep deprivation(损失), Kutcher says.
Then there’s the breakfast issue. Dr. Carlyle Smith, a sleep researcher and a psychology professor at Trent University in Peterborough, Ont., adds that many teens simply cannot tolerate food when they first wake up, so skipping breakfast becomes another factor in reduced alertness in class. The most obvious solution to the teen sleep problem is to have school start later in the day, but initiatives(积极性) toward this across the country have gone nowhere, Smith says, mainly because of costs and resistance from school boards and teachers.
So for now, just sympathize with your teens. Encourage them to go to bed, if not early, then at least at a regular time, so they won’t develop insomnia from erratic(不稳定的) schedules. Warn them not to have too many caffeinated drinks before bed. And don’t let sleeping away the weekend become an issue to fight over. Schedule family activities to take place later in the day on weekends and let them sleep in. “If you want your kids to grow and remember stuff, let them sleep,” says Smith. “It’s not laziness. Their brains are working really, really hard.”

I’ve written 14 movies. My characters smoke in many of them, and they look cool and glamorous doing it. Smoking was an integral（必需的） part of many of my screenplays because I was a heavy smoker. It was part of a bad-boy image I’d cultivated for a long time— smoking, drinking, partying, rock ’n’ roll.

       Smoking, I once believed, was every person’s right. The second-hand smoke was non-existent problem invented by professional do-gooders. I put all these views into my plays.

       Remembering all this, I find it hard to forgive myself. I have been an accomplice （帮凶） to the murders of untold numbers of human beings. I am admitting this only because I have made a deal with God. Spare me, I said, and I will try to stop others from committing the same crimes I did.

Eighteen months ago I was diagnosed with throat cancer, the result of a lifetime of smoking. I am alive but disabled. Much of my larynx （喉） is gone. I have some difficulty speaking; others have some difficulty understanding me.

       I haven’t smoked or drunk for 18 months now, though I still take it day by day and pray for help. I believe in prayer and exercise. I have walked five miles a day for a year, without missing even one day. Quitting smoking and drinking has taught me the hardest lesson I’ve ever learned about my own weakness; it has also given me the greatest affection and empathy（同感） for those still addicted.

      I don’t think smoking is every person’s right anymore. I think smoking should be as illegal as heroin. I’m no longer such a bad boy. I go to church on Sunday. I’m desperate to see my four boys grow up. I want to do everything I can to undo the damage I have done with my own big-screen words and images.

       Screen writers know, too, that some movie stars are more likely to play a part if they can smoke —because they are so addicted to smoking that they have difficulty stopping even during the shooting of a scene.

       My hands are bloody; so are Hollywood’s. My cancer has caused me to attempt to cleanse me. I don’t wish my fate upon anyone in Hollywood, but I beg that Hollywood should stop putting it upon millions of others.
