Whether you prefer burning the midnight oil or goingto bed early so you can get up at the crack of dawndepends on your genes, according to experts.
I leap out of bed each morning, keen to start anactive day. But I can hear my neighbour's alarm clockringing non-stop every morning and I doubt he gets to work on time.
A lot of noise comes from his flat in the evening. He's happy to stay up watching telly till thewee small hours, while I turn in early and try to sleep.
Well, it might not be his fault after all. Neurogeneticist Dr Louis Ptacek of University of Californiawould say I'm 'a lark' and my neighbour is 'an owl'. Families of 'extreme owls', with FamilialDelayed Sleep Phase syndrome, were found to have a different mutation in the same genes.
We all have internal 'clocks' located in the part of the brain which controls all kinds of bodilyfunctions and it is reset every day by light. These internal clocks run to a different schedule in'larks' and 'owls'. If you have a fast clock, you like to do things early, and if you have a slowclock, you like to do things late.
Because we live in a 24/7 world, scientists believe it's important to understand a person's'chronotype' – the time of the day when they function the best. It could help us lead ahealthier life.
Prof Till Roenneberg of Ludwig-Maximilians University in Munich has studied sleeping patternsand thinks work times should be changed and made more individual to fit in with ourchronotypes.
And he has advice for those who can't choose their work shifts: "If that's not possible, weshould be more strategic about light exposure", says Prof Roenneberg. "You should try to goto work not in a covered vehicle but on a bike. The minute the sun sets we should use thingsthat have no blue light, like computer screens and other electronic devices."
So what about you? Are you 'a lark' or 'an owl'? 【不要走开，精彩内容请看下一页】
