Hours of Sleep
Information
Experts say that teenagers, up until
their twenties, need about 9.2 hours of
sleep each night. Less sleep makes
kids less aware and lowers grades. Our
survey found that there is a correlation
between sleep and grades. If you get
less sleep, you don’t get as good
grades. Puberty changes teenagers’
internal clocks so that the proper levels
Information
of melatonin needed to fall asleep easily aren’t
produced until around 11:00 PM. Large
amounts of homework can make kids stay
awake later, and early school start times keep
them from getting more sleep. Once they hit
adolescence, teenagers need more sleep than
adults and young children do. We have found
that the optimal amount of sleep for teenagers
is around 8 to 10 hours, fitting in with what
experts say. In conclusion, if you want students
to get better grades, they need more sleep.
