Many of America`s adolescents drive while drowsy, oversleep, and get sleepy in class: They are going through life sleep-deprived. Only 20 percent of teens get the recommended nine hours of shut-eye on school nights, and more than one in four report sleeping in class, according to the recent poll by the National Sleep Foundation.
What`s more, the poll finds that parents are mostly in the dark about their adolescents` sleep habits. While most students know they`re not getting the sleep they need, 90 percent of parents polled believe their adolescents are getting enough sleep on school nights. A quick sampling of teens by a news reporter found the poll was on target, with most saying they have trouble getting up in the morning.
17-year-old Carl Woock is one of these typically tired teens. He let the reporter follow him through a typical weekday, during which exhaustion surfaced several times. It starts with an alarm clock and getting ready for school, where Carl`s classes in suburban Maryland start at the early hour of 7:30 am. For some, that`s just too early, and he often falls asleep in class. Thinking is one of the things that gets sacrificed without enough sleep.
"In the competition between the natural tendency to stay up late and early school start times, a teen`s sleep is what loses out," said Dr.Jodi A. Mindell. Another researcher pointed out that puberty changes the body`s "circadian rhythm." She explained that an 8 to 10-year-old is able to fall asleep at 9 at night, but a 13 to 15-year-old has their circadian rhythm shifted, so that they`re not able to fall asleep until 12 at night naturally. She warned that there`s more in a teen`s life that`s affected by sleep deprivation. She said, "They are moody. Depression is a concern. It affects every aspect of their lives."
Without enough sleep, a person has trouble focusing and responding quickly, according to the National Institutes of Health. The agency also said there is growing evidence linking a continuous lack of sleep with an increased risk of serious illness.
The National Sleep Foundation reported that nearly all youngsters have at least one electronic item, such as a television, computer, or phone in their bedrooms. Adolescents with four or more such items in their bedrooms are much more likely than their peers to get an insufficient amount of sleep at night. They are also almost twice as likely to fall asleep in school and while doing homework.
For many teens, one solution to the problem comes in a cup, with many saying they drink lots of coffee. The caffeine may help teens perk up during the day, but it might be only masking the underlying biological reason for their sleep habits.
Teens might want to take some advice from experts, who recommend saying goodbye to the entertainment zone in the bedroom, cutting out caffeine after lunchtime, setting up a daily sleep and wake-time routine, and being aware that trying to catch up on your sleep at weekends upsets your natural body rhythm.
