Shelly Nielsen sees students fall asleep in class at least twice a week. “When I see teens asleep in my class, I wonder if I am really that boring”, said Nielsen, a teacher. “I also wonder why they are so tired.” Neilson first tried to wake up sleeping students quietly. If the snoozing (呼噜声) continues, she may call a student’s parents to find out how much sleep the students is getting at night and why.
According to a research, teens need at least nine hours of sleep to function properly during the day. And more than 90 percent of teens say they are sleeping less than that each night.
Forgetting homework, yawning in class, losing concentration --- these are the signs of a sleep-deprived (被剥夺睡眠的)student, said Dr. Carl Lawyer, a specialist. “The big problem is the social demand for homework, video games and friends. Teens don’t understand how important sleep is.”
Rebecca Lucas, another teacher agrees. “Teens are busy,” she said, noting many activities most teens are involved in during the day force them to get home pretty late.” When I see teens sleeping in my class, I feel sad, like they are not sleeping enough,” she said. “I also feel frustrated because I have so much to teach in such a short amount of time and teens sleeping in the class slows me down.”
Not sleeping the needed number of hours can affect your day very much. The effect is on school, work and driving and is very frustrating to teachers when students don’t do their best because of being so tired, Lawyer said.
Al Taylor, a teacher says sleeping is not allowed in his class. “When I see a teen sleeping in my class, I feel bad that they didn’t get enough sleep but they need to correct the issue at home,” Taylor said. “I’ve raised teenage boys myself. Teenagers like to wait to the last minute to do their homework so they often stay up late trying to finish it.”
