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'?

据专家说，你是喜欢开夜车还是喜欢早早上床睡觉黎明时分起床，取决于你的基因。
我每天都很早从床上跳起来，迫切而积极地开始一天的生活。但是我每天都能听到我邻居的闹钟响个不停，我很怀疑他能否准时去上班。
晚上，他的公寓里总是传来很多噪音。他每天都开心地看电视到深夜，而我却早早地上床睡觉。
不过，这或许不是他的错。来自加州大学的神经基因学家Louis Ptacek博士会说我是一只“百灵鸟”，我的邻居是“猫头鹰”。科学家发现，“极端猫头鹰”家族患有家族性睡眠相位后移症，家族成员出现同样的基因突变。
我们的大脑中都有内在的生物钟，控制着所有的身体生理机能，每天都通过光线来重新设置。“百灵鸟”和“猫头鹰”的内在生物钟运作方式不同。如果你的内在钟表走得比较快，你就喜欢早点做事。如果你的内在钟表比较慢，你喜欢晚一点做事。
因为我们生活在一个时时刻刻转动着的世界，科学家们相信，了解一个人的“时型”非常重要——也就是一个人一天当中生理机能运作最佳的时候。这样可以帮助我们过更加健康的生活。
路德维希-马克西米利安-慕尼黑大学的Prof Till对睡眠模式进行了研究，认为工作时间应该进行调整，根据个人的“时型”进行个性化对待。
对于那些不能选择工作时段的人他也有一些建议：“如果调整工作时间不可能，我们应该在光线暴露方面更有战略性。最好不要乘坐密封的交通工具，而是骑自行车。日落的时候我们应该使用没有蓝光的工具，例如电脑屏幕和其他电子备。”
那么你呢？你是“百灵鸟”还是“猫头鹰”？
