如果你睡得太多，对你的身体没有任何好处

It seems we're always being told to get more sleep — and for good reason.

似乎我们总是被告知要多睡觉——而且理由很充分。

Studies suggest skimping on sleep can lead to obesity, diabetes and even cancer. You might even find yourself with a head-full of false memories.

研究表明，睡眠不足会导致肥胖、糖尿病甚至癌症。你甚至可能会发现自己头脑中充满了错误的记忆。

But rarely does science explore the dark side of sleeping too much. Maybe that's probably because few of us in today's work-addled world have the luxury of exploring that option.

但科学很少探索睡眠过多的阴暗面。也许这是因为，在如今这个工作充斥的世界里，很少有人有机会探索这种选择。

It turns out, even that end of the sleep spectrum is not without its perils.

事实证明，即使是睡眠光谱的这一端也存在危险。

In a new study published in the journal Neurology, researchers plumbed the sleep patterns of those "fortunate" few — and found they may not be so lucky after all.

在《神经学》杂志上发表的一项新研究中，研究人员调查了那些“幸运的”少数人的睡眠模式，发现他们可能根本就没有那么幸运。

In fact, they found that people who take long naps or who sleep nine or more hours at night may have a greater risk of stroke than those who get less sleep.

事实上，他们发现午睡时间长或晚上睡9个小时以上的人比睡眠不足的人患中风的风险更大。

In a similar study published in the Journal of the American Heart Association, researchers found people who get more than eight hours of sleep have greater mortality and cardiovascular risk compared to those who cobbled together less than seven hours.

在《美国心脏协会杂志》上发表的一项类似研究中，研究人员发现，睡眠时间超过8小时的人与睡眠时间不足7小时的人相比，死亡率和心血管疾病风险更高。

What's more, sleep-aholics — those who manage to get 10 hours a night — stood a 30% higher chance of dying compared to the seven-hour crowd.

更重要的是，睡眠狂——那些每晚睡10个小时的人——与睡7个小时的人相比，死亡率要高出30%。

"Our study has an important public health impact in that it shows that excessive sleep is a marker of elevated cardiovascular risk," lead researcher Chun Shing Kwok of Keele University notes in a press release.

“我们的研究对公众健康有重要的影响，因为它表明，睡眠过多是心血管风险升高的一个标志，”基尔大学首席研究员郭春成在一份新闻稿中指出。

In any case, the research points to a new and possibly life-saving line of questioning at the doctor's office: Namely, how much do you sleep?

无论如何，这项研究指出了医生办公室里一个可能挽救生命的新问题:也就是，你睡了多久?

"The important message is that abnormal sleep is a marker of elevated cardiovascular risk and greater consideration should be given in exploring both duration and sleep quality during patient consultations," Kwok says.

“重要的信息是，不正常的睡眠是心血管风险升高的一个标志，在病人咨询期间，应该更多地考虑探索持续时间和睡眠质量，”郭说。

The researchers admit that sleep is a many-splintered thing — and the amount we can scrape together on any given day fluctuates wildly. It isn't like a multivitamin that we can pop daily and be assured of healthful results.

研究人员承认，睡眠是一个由许多碎片组成的东西，我们每天能勉强拼凑起来的睡眠量波动很大。它不像我们每天摄入的多种维生素那样保证有益健康。

"The amount and quality of our sleep is complex," Kwok explains. "There are cultural, social, psychological, behavioral, pathophysiological and environmental influences on our sleep such as the need to care for children or family members, irregular working shift patterns, physical or mental illness, and the 24-hour availability of commodities in modern society."

“我们的睡眠量和质量是复杂的，”郭解释说。“我们的睡眠会受到文化、社会、心理、行为、病理生理和环境方面的影响，比如照顾孩子或家人的需要、不规律的工作模式、身体或精神疾病，以及现代社会中24小时供应的商品。”

We are indeed living in an increasingly time micro-managed society.

我们确实生活在一个越来越微观管理的社会。
