Late for school
As they prepare a major study to test the idea,
UK scientists have said that starting school at
10 am could have huge benefits for teenagers.
Research suggests that society pays too little
attention to our "body clock" and adolescents
in particular have a late-running biological
rhythm. This means insisting on an early start
can cause sleep deprivation, which in turn can
affect learning and health.
A sleep expert made the argument at the British
Science Festival in Bradford. Dr Paul Kelley said
that adolescents effectively lose up to two hours
of sleep per day, which is "a huge society issue."
He and colleagues from Oxford are leading a
project called Teensleep, which is currently recruit-
ing 100 schools from around the UK to take part
in what Dr Kelley called "the world s largest ran-
domised control trial," due to commence in 2016.
Ups and downs
Our body clock is a daily cycle which drives the
regular rise and fall of certain genes as well as the
ebb and flow of our cognitive performance, our
metabolism and so on. For much of our lives---
and especially in adolescence---there is a mismatch
between this rhythm and the typical working day.
In fact, Dr Kelley said, the body clock of most
people between age ten and 55 is not well suited
to rising early.
He said: "Most people wake up to alarms,
because they don t naturally wake up at the time
when they have to get up and go to work. So we ve
got a sleep deprived society---it s just that this age
group, say 14 to 24 in particular, is more deprived
than any other sector."
Dr Kelley and his colleagues, including well-
known Oxford sleep researcher Prof Russell Foster,
argue that school days should start at 10 am and
university at 11 am, to better match the circadian
rhythms of adolescents and young adults.
"All the evidence points to the same thing," Dr
Kelley told BBC News." There are no negative out-
comes for moving (the school day) later, no positive
outcomes for moving earlier."
The Teensleep experiment, which is funded by
the Wellcome Trust and the Education Endowment
Fund, will randomly assign its 100 schools into
One group of schools will shift their school days
for 14 to 16-year-olds to a 10 am start---another
group will offer "sleep education" to their students.
This involves "helping students and staff realise
sensible ways of making their sleep good sleep,"
Dr Kelley said, such as avoiding screen-based
activity in the evening. A third group of schools
will introduce both a later start and sleep edu-
cation, while a fourth, control group will make
no such changes.
The interventions will commence in the 2016
to 2017 academic year, and the researchers plan
to report their results in 2018.
Derk-Jan Dijk is a professor of sleep and phys-
iology at the University of Surrey. He cautioned
that shifting the school day might be of limited
use without changing other habits that affect our
sleep, especially night-time light exposure---making
the education part of the trial particularly impor-
"It is clear that these adolescents tend to drift
later. And many of them will probably prefer to
start later," he told the BBC. "But why do ado-
lescents like to sleep in later and go to bed later?
What is causing this? There is undoubtedly a bio-
logical component, but that interacts with our
Scientists: Teens need
later start to school day
artificial light environment.
"And, if we can t change that, then is delaying
school times the best solution? Because that
way you might not solve the problem---you
might shift them even later."
Prof Dijk said the Teensleep experiment was
an important one, which he would observe
with interest. "It will be very interesting to see
