Paul Kelley – a sleep expert from the University of Oxford – says that most people are getting up too early. He believes work and school should start a few hours later. Many companies are starting to realise more sleep can mean a more productive workforce and are changing work schedules. While in South Korea, office workers are heading to relaxation parlours at lunchtime to take power naps in hammocks or massage chairs. This is much healthier than catching forty winks while sitting on the toilet or dropping off at their desks.

So, if like me you find yourself hitting your snooze button every morning – don't feel bad. It’s just our body clocks!
