Hey there! Welcome to Life Noggin.
大家好！欢迎来到脑洞大开的生命奇想。
What if you only slept a couple of hours every night? Is sleep really that important to your health and well being?
如果你每晚只睡几个小时会怎么样？睡眠对你的健康幸福真的很重要吗？
Let's find out together. And then maybe we'll take a well-earned nap. Well, it looks like some people might only really need a few hours of sleep.
我们一起寻找答案吧！然后也许我们能好好睡一觉。有些人可能真的只需要睡几个小时。
Called "short sleepers" or the "sleepless elite", these individuals might make up about 1% of our society and are the early birds and night owls of the world, only needing a few hours a night with the sandman.
这些人被称为“少眠者”或“不眠精英”，他们大约占我们总人口的1%，是早起鸟和夜猫子，他们每晚只需要和睡眠精灵共度几个小时。
Maybe even just 1! However, some scientists disagree on if these individuals are still at their best health at only a few hours of sleep a night.
甚至只有1小时！然而，如果这些人在每晚只睡几个小时，他们的健康是否仍处于最佳状态？很多科学家就此问题各执己见。
And even if they are and this is true, keep in mind that they're only a very small percent of the population.
即使他们的健康真的不受影响，记住，那只是一小部分人。
Most of us need quite a few more hours of sleep a night than that. But just how much?
我们大多数人每晚都需要多睡几个小时。但到底有多少呢？
The National Sleep Foundation recommends that adults get between 7-9 hours of sleep and teenagers get around 8-10.
美国国家睡眠基金会建议成年人保持每天7-9小时的睡眠时间，青少年保持8-10小时的睡眠时间。
This amount increases the younger a person is, with newborn babies needing 14-17 hours of sleep for optimal health.
年龄越小，需要的睡眠时间越长，新生儿需要14-17个小时的睡眠才能保持最佳的健康状态。
And for all my teenage friends who find it hard to stay awake in class, the sleep experts at the National Sleep Foundation have your back.
那些在课堂上很难保持清醒的青少年朋友们，国家睡眠基金会的睡眠专家们支持你们。
They say your biological internal clocks help keep you awake later in the evening, making it so that you want to stay asleep during those early morning classes.
他们认为，你的生物钟让你在夜里十分清醒，这样你在清晨的课堂上就会想睡觉。
Phew! I thought it was just me. It seems like getting the right amount of sleep is important to staying healthy for most people.
唷！我觉得这就是我本人了。对大多数人来说，适量的睡眠似乎对于保持健康很重要。
With a study that looked at older adults, researchers found that sleeping less than 6 hours or more than 10 hours a night was associated with a higher likelihood of healthcare use.
研究人员对老年人进行了一项研究，发现每晚睡眠时间少于6小时或超过10小时的人更有可能进医院。
Shorter sleep durations were linked with greater odds of emergency department visits and longer sleep durations linked up with greater odds of overnight hospital stay.
睡眠时间较短往往更有可能去急诊，睡眠时间较长，更有可能住院。
Maybe the saying should be the right amount of sleep a day can keep the doctor away! Yeah, let's make it that, cause I'm not really a big fan of apples.
也许那句话应该这样说：每天睡适量，医生远离我！好吧，就这么说吧，因为我不太喜欢苹果。
Disrupting your sleep seems to have negative consequences on your health as well.
睡眠被打断对健康也有负面影响。
Based on current studies, sleep disruption has been reported to increase the risk of incident dementia.
目前的研究认为，睡眠中断增加了患痴呆的风险。
One such study examined 737 older adults and found that greater amounts of sleep fragmentation was associated with an increase in cognitive decline.
其中一项研究对737位老年人进行了调查，发现睡眠被打断次数越多，认知能力衰退越严重。
Sleeping less also seems to have a correlation with Alzheimer's disease, which is the most common form of dementia.
睡眠不足似乎也与阿尔茨海默氏症有关联，那是最常见的痴呆症。
In a 2017 review article published by the Oxford University Press, it's been hypothesized that human's natural selection for shorter sleep cycles has compromised the efficacy of the physiological mechanisms that protect us against Alzheimer's disease during sleep.
2017年，牛津大学出版社(Oxford University Press)发表的一篇评论文章猜测，睡眠期间某种机制帮助我们抵御阿尔茨海默氏症，人类的自然选择缩短了睡眠周期，将这种机制的功效削弱。
They believe this because humans sleep less than other primates, but have a much higher prevalence of Alzheimer's disease pathology.
他们这样认为，是因为人类睡眠时间比其他灵长类动物少，但老年痴呆症的发病率却高得多。
This article was very recent, but further research to shed more light on this could potentially go a long way with protecting people from Alzheimer's disease!
这篇文章是最近发表的，但进一步的研究进一步阐明这个问题，可能还有很长的一段路，才能保护人们远离阿兹海默症！
Long story short, you should probably get some sleep, because your body depends on it.
长话短说，你应该睡一觉，因为你的身体需要睡眠。
So what have you found to be the best amount of sleep for you? Any tips on how to catch a few more Z's? Let us know in the comments below.
那么，你认为最适合你的睡眠时间是多久？有没有帮助提高睡眠质量的建议？请在下面的评论中告诉我们。
