Later class times start could help improve adolescents' performance at school.

I think many students have the same experience like me, didn’t get enough of sleep in the night and wake up early in the other day for school. It's hard to wake up at 6 or 7 although you settled a series alarms. When the alarm rings out at 7 am in the morning, the feeling is equal to someone wake you up at 3am. Some students like a zombie at school when they don’t get enough sleep; some of them just sleep in the class. Teenagers’ biological time dictates a need for nine hours of sleep, and later sleep and wake times. Specially, their body is growing up in the adolescence. By the way, if a student has been sleep deprived over a long period of time, it will impair physiological, metabolic and psychological health.

The result from Harvard and Oxford reseachers show most middle and high school were starting at 8am , it's too early. If we can't force students go to bed early so why don’t we start school later every morning? 


I strongly agree with you on this one JImmy! The mornings are rough for all students except for the rare few that have the god given trait of being early birds. If school were to start even a mild hour later, it would make an enormous difference in our development process. Or at least, if we are to start this early, we should be given less homework to give us more time for leisure activities and sleep. Because let's be honest, no kid is going to come home from school, do their homework and go straight to bed without having a bit of entertainment.

I don't understand something in your last sentence:If we can force students go to bed early so why don’t we start school later every morning?. The link between being able to force students to go to bed early followed by the question why not start school later is unclear to me. I think it is a red herring because being able to force students to go to bed earlier has no connection with your conclusion that school should start later. You're welcome to correct me if I misunderstood you.

Thanks for remind me this mistake, I wanted to write "can't "

What you said is true but you should have put some references like this blog which is from a specialist of the teenager brain: . From a personnal point of view, it is true that I go to sleep very late so I am not as concentrate in the morning, but I do not know if it is the case for every students. Probably not.
