An Oxford University researcher has determined that employees should begin work at 10 am to avoid illness and exhaustion, as reported by The Telegraph.
Before the age of 55, the circadian rhythms of adults are completely out of sync with normal 9-to-5 working hours, which poses a “serious threat” to performance, mood and mental health.
Dr Paul Kelley, of Oxford University, said there was a need for a huge societal change to move work and school starting times to fit with the natural body clock of humans.
Experiments studying circadian rhythms have shown that the average 10-year-old will not start focussing properly for academic work before 8.30am. Similarly, a 16-year-old should start at 10am for best results and university students should start at 11am.
Dr Kelley believes that simply moving school times could raise grades by 10 per cent. He was formerly a head teacher at Monkseaton Middle School, in North Tyneside, where he changed the school start day from 8.30am to 10am and found that the number of top grades rose by 19 per cent.
