Sleep is food for the brain. During sleep, important body functions and brain activity occur. Skipping sleep can be harmful — even deadly, particularly if you are behind the wheel. You can look bad, you may feel moody, and you perform poorly. Sleepiness can make it hard to get along with your family and friends and hurt your scores on school exams, on the court or on the field. Remember: A brain that is hungry for sleep will get it, even when you don’t expect it. For example, drowsiness and falling asleep at the wheel cause more than 100,000 car crashes every year. When you do not get enough sleep, you are more likely to have an accident, injury and/or illness.
Not getting enough sleep or having sleep difficulties can:
If teens need about 9 1/4 hours of sleep to do their best and naturally go to sleep around 11:00 pm, one way to get more sleep is to start school later.
Teens’ natural sleep cycle puts them in conflict with school start times. Most high school students need an alarm clock or a parent to wake them on school days. They are like zombies getting ready for school and find it hard to be alert and pay attention in class. Because they are sleep deprived, they are sleepy all day and cannot do their best.
Schools that have set later bell times find that students do not go to bed later, but get one hour more of sleep per school night, which means five hours more per week.
Enrollment and attendance improves and students are more likely to be on time when school starts. Parents and teachers report that teens are more alert in the morning and in better moods; they are less likely to feel depressed or need to visit the nurse or school counselor.
While everyone is accustomed to having a bad morning here and there – feeling irritable, unhappy or even sad, NSF’s 2006 Sleep in America poll found that many adolescents exhibit symptoms of a depressive mood on a frequent if not daily basis, and these teens are more likely to have sleep problems.
The NSF poll calculated depressive mood scores for each of the 1,602 poll respondents by measuring adolescents’ responses to four mood states (using a scale of “1” to “3” where 1 equals “not at all” and 3 equals “much”):
The results showed that about half (46%) of the adolescents surveyed had a depressive mood score of 10 to 14, 37% had a score of 15 to 19, and 17% had a score of 20 to 30; these scores are considered low, moderate and high respectively.
Most notably, those adolescents with high scores ranging from 20 to 30 were more likely than those with lower scores to take longer to fall asleep on school nights, get an insufficient amount of sleep and have sleep problems related to sleepiness. In fact, 73% of those adolescents who report feeling unhappy, sad, or depressed also report not getting enough sleep at night and being excessively sleepy during the day.
While many adults may think that adolescents have things easy or don’t have much to worry about – the opposite seems true according to the NSF poll. Most adolescents were likely to say they worried about things too much (58%) and/or felt stressed out/anxious (56%). Many of the adolescents surveyed also reported feeling hopeless about the future, or feeling unhappy, sad or depressed much or somewhat within the past two weeks of surveying.
Research shows that lack of sleep affects mood, and a depressed mood can lead to lack of sleep. To combat this vicious cycle, sleep experts recommend that teens prioritize sleep and focus on healthy sleep habits. Teens can start by getting the 8.5 to 9.25 hours of sleep they need each night, keeping consistent sleep and wake schedules on school nights and weekends, and opting for relaxing activities such as reading or taking a warm shower or bath before bed instead of turning on the TV or computer.
“If parents and teens know what good sleep entails and the benefits of making and sticking to a plan that supports good sleep, then they might re-examine their choices about what truly are their ‘essential’ activities,” says Mary Carskadon, Ph.D., Director of Chronobiology/Sleep Research at the E.P. Bradley Hospital and Professor of Psychiatry and Human Behavior at Brown Medical School in Providence, R.I. “The earlier parents can start helping their children with good sleep habits, the easier it will be to sustain them through the teen years.”
