Do
you

at
school
?
You
probably
need
more
sleep
-
to
doctors
,
teenagers
have
to
get
at
least
nine
hours'
sleep
a
night
.
However
,
it's
not
just
how
much
sleep
you
get
that's
important
.
What
you
do
you
go
to
bed
also
has
a
huge
effect
on
how
you
feel
the
next
day
.
If
you
spend
time
chatting
to
someone
on
social
media
,
or
reading
a
book
on
your
e
-
reader
,
you
are
not
alone
.
However
,
you
ought
to
reduce
your
screen
time
at
night
.
scientists
are
only
just
beginning
to
understand
the
full
effects
,
the
main
message
is
that
using
devices
like
phones
or
tablets
before
is
not
good
for
your
health
.
All
devices'
screens
give
out
a
large
amount
of
blue
light
.
That
isn't
a
problem
you
want
to
go
to
sleep
.
This
blue
light
affects
the
body
?
s
production
of
the
sleep
hormone
,
melatonin
,
which
can
change
your
sleep
patterns
,
or
circadian
rhythms
.
So
,
it
isn't
just
getting
to
sleep
that
becomes
hard
,
but
the
quality
of
your
sleep
also
suffers
.
The
result
is
that
you
can
wake
up
times
during
the
night
and
have
difficulty
getting
up
in
the
morning
.
Sleep
is
food
for
the
brain
,
so
not
sleeping
well
can
be
a
serious
problem
for
anyone
,
but
is
especially
bad
for
,
because
their
brains
are
still
developing
.
When
you
don
?
t
sleep
well
,
it
can
be
difficult
to
at
school
,
which
makes
it
harder
to
and
get
good
grades
.
It
can
also
affect
your
mood
,
making
you
feel
sad
or
anxious
.
So
,
it
?
s
clear
you
shouldn
?
t
use
your
phone
or
tablet
before
you
go
to
sleep
.
Why
not
leave
your
phone
in
another
room
?
You
mustn't
worry
about
your
.
Nothing
on
social
media
is
so
important
that
it
can't
wait
a
few
hours
!
You
should
rediscover
paper
books
and
enjoy
feeling
tired
and
sleepy
before
bedtime
rather
than
why
your
best
friend
hasn't
liked
your
photo
!
How
will
you
wake
up
?
You
don't
have
to
use
the
alarm
on
your
phone
.
Go
and
buy
yourself
an
old
-
fashioned
alarm
clock
!
The
negative
effects
that
screen
time
is
having
on
sleep
has
been
in
the
news
a
lot
recently
,
so
of
smartphones
and
tablets
have
added
a
feature
to
their
devices
that
can
help
reduce
these
.
Most
new
phones
have
a
night
-
time
that
changes
the
colour
of
the
screen
so
that
it
gives
out
less
blue
light
.
So
,
if
you
really
can't
avoid
going
onto
social
media
at
bedtime
,
you
ought
to
think
about
turning
on
this
setting
on
your
phone
.

Throughout
history
,
people
have
written
about
events
in
their
lives
.
In
the
past
,
people
kept
diaries
,
and
these
documents
are
helpful
to
experts
,
who
are
able
to
understand
important
events
in
history
.
These
days
,
people
keep
a
record
of
their
lives
by
a
blog
instead
.
There
are
differences
between
blogs
and
diaries
,
however
.
Diaries
require
only
a
pen
and
paper
while
blogs
require
a
computer
,
access
to
the
internet
and
something
entertaining
to
write
about
.
This
could
be
something
you
?
ve
done
or
something
you
did
a
while
ago
.
Diaries
of
the
past
were
often
with
drawings
,
while
blogs
often
include
photos
,
videos
and
links
.
Whatever
their
differences
,
though
,
both
diaries
and
blogs
are
important
records
of
life
which
will
be
interesting
for
people
to
read
in
the
future
