Start school day at 11am to let students sleep in, says expert

Paul Kelley says young people are losing 10 hours' sleep a week, and calls for 8.30am starts for primary pupils and 10 or 11am for teenagers

School start times should be put back to as late as 11am to combat a sleep-deprivation crisis among young people, a scientist has suggested.

Paul Kelley, of the Sleep and Circadian Neuroscience Institute at the University of Oxford, said young people in Britain were losing on average 10 hours' sleep a week, making them more sleep-deprived than a junior doctor on a 24-hour shift.
