A new law responds to research showing the effects of early starts and sleep deprivation on teens
Save time by listening to our audio articles as you multitaskSince the 1950s Americans have been moving away from cities to sprawling suburbs with limited public transport. Families became car-dependent and buses were used to get pupils to school. But to save money schools often have to share bus fleets. High-schoolers are usually picked up first, then middle school, to prevent elementary pupils from waiting in the morning darkness.
Concentration suffers. A county in Kentucky that pushed back its school-start time found that car-crash rates among teen drivers fell by nearly 17% . More sleep boosts academic performance. A study of 29 schools in seven states found that attendance and graduation rates improved after start times were moved to after 8:30am.
So why don’t the teens just go to bed earlier? During puberty, adolescents’ sleep cycle changes. They begin to go to sleep later and wake up later as well. But they still require a full night’s rest—8.5 to 9.5 hours, according to theSceptics worry that delaying school starts will not result in more sleep because teens will only go to bed even later. But this does not seem to happen. A meta-analysis found that later school-start times do indeed lead to more sleep.
