We all know that teenagers like to sleep late. But more and more research is showing that this is not just
a preference-or even the result of late-night studying or instant messaging-but is rooted in their biological
rhythms(节律). All of this would be little more than an interesting observation except that most high schools
start so early, and so many teenagers are having a hard time staying awake.
A recent article in The Times cited a National Sleep Foundation survey in which more than a quarter of
the students reported that they fell asleep in class at least once a week. Researchers say this is true because
youngsters - beginning around age 12 until they reach their mid-20s-only start producing melatonin, the
sleep-inducing hormone(荷尔蒙), around 11:00 pm and that production lasts until about 7:00 am. In adults,
melatonin lasts to around 4:00 am. Trying to wake up a teenager before 7:00 am is like trying to awake an
adult before 4:00 am.
The obvious remedy(补救)would be for high schools to start later-well, after 8:00 am. A handful of
schools that have switched have reported beneficial results. School officials in Minneapolis say that
attendance improved and students' grades rose slightly after they changed to start at 8:40 am several years
ago. In Wilton, Conn., where the high school start time was pushed back to 8:20 am from 7:35 am, teachers
and parents reported better student behavior and greater alertness. Surveys of students in both districts
indicated that they did not use the later starts as an excuse to go to bed later.
Numerous districts have considered the idea of later high school hours, only to drop it because of fierce
adult opposition. Coaches complain that the later classroom hours in the afternoon would take time from
their training programs and teams' success. School bus companies would be forced to change their
schedules. And many parents complained that they would have to adjust their own schedules.
Many schools officials say more research is needed. We're all for that and for remembering that the goal
is to educate youngsters-and for that they need to be awake.
