How bad habits affect your sleep?

影响睡眠的坏习惯

You're sleeping too much

睡的太多

Is there such a thing as too much sleep?It seems so.

睡的太多也对身体有害?似乎是这样。

According to sleep experts at Sweden's Katolinska Insitute having an irregular sleep schedule confuses our naturalcycle.

据瑞典卡罗林斯卡学院的睡眠专家表示，睡眠时间不规律会打乱我们的生理周期。

Sleeping in really late, taking longnaps, or ones that are late in the evening means you won't have an appetite for regular sleep and it will leave you feeling jet-lagged.

睡到很晚，打盹儿时间长，或者晚上熬夜都说明你不喜欢规律睡眠，这会让你感觉时差颠倒。

That's not to say you shouldn't catch afew extra Zzzs at the weekend though, just keep your wake up time to within 30minutes of the time you get up during the week otherwise you can start to mess up your sleep cycle.

但并不是说你不应该在周末多补充一些睡眠，只不过要保证周末起床时间不晚于工作日起床时间半个小时，不然就是在打乱自己的睡眠周期。
