成年人需要的睡眠时间更少吗?

Do Adults Need Less Sleep? | Matthew Walker

成年人需要的睡眠时间更短吗?
So one of the myths that’s out there is that
有一个在外流传的谬论说
older adults actually need less sleep
比起中年人和青年人
than middle-aged adults or young adults.
老年人所需的睡眠时间更少
It turns out not to be true. It actually is a myth.
事实并非如此 它的确是个谬论
Older adults need just as much sleep as they do in their seventies,
老年人所需的睡眠时间 与他们70多岁时需要的相同
as they did when they were in their forties.
也和40多岁时的睡眠时间一样长
The problem is that it’s simply older adults cannot generate the sleep that they still necessarily need.
问题是 他们只是睡不够身体必需的睡眠时长
So the analogy would be like saying well,
其实 这就类似于这么说
older adults have weaker bones as they get older,
老年人的骨质因年长而变得脆弱
and therefore older adults just need less strong bones.
因此 他们并不需要强壮的骨质
And that’s not true.
当然这不是真的
We accept that it’s a problem
我们接受了这是个问题
and we treat it with supplements such as calcium.
并使用一些补给品来治疗它 比如钙
We need to do the same thing and have the same mentality approach
回到老年人的睡眠问题 我们应该做同样的事情
when it comes to older adults’ sleep.
并且采取同样的心态
We need to help them with their sleep,
我们需要帮助他们处理睡眠问题
think about strategic ways to improve their sleep
想出一些策略来提升他们的睡眠质量
because they still need that sleep.
因为他们确实需要充足的睡眠
And in fact we know that
事实上 我们都知道
sleep is one of the most protective lifestyle factors
睡眠是一种最具防御性质的生活要素
that determines your dementia and Alzheimer’s disease risk as well.
它会影响痴呆症和阿尔兹海默症的发病几率
So for all of these reasons we need to let go of the…the myth.
综上所述 我们不能再允许这个谬论流传下去了
And it truly is a myth that older adults simply need less sleep.
老年人睡眠时间短这确实是谬论啊
They don’t. They need just as much sleep.
他们需要的睡眠时间跟其他人一样
They just can’t physically generate it as the brain starts to deteriorate.
只是 由于大脑机能开始衰退 他们无法睡不了那么久
So we need to find ways to supplement it.
所以我们需要找到弥补的方法
So how could we actually supplement the sleep of older adults?
那么我们该如何真正地弥补老年人睡眠不足的问题呢
Well, one thing that we’re developing at my sleep center
在加利福尼亚大学伯克利分校
at the University of California Berkeley,
我的睡眠研究中心
is something called direct current brain stimulation.
正在研发一种名为直流电脑部刺激的方法
Now it sounds like the stuff of science fiction.
它现在听起来像是科幻小说里的东西
It’s actually science fact
但它实际上是科学事实
You apply some electrode pads to the head,
把一些通电的贴片放置在头部
and you insert a small amount of voltage into the brain.
然后往脑部推进少量电流
So small that you typically don’t feel it,
电流量少到你几乎感觉不到它
but it has a measurable impact.
但它有着显著的效果
And what we’re trying to do is essentially sing in time
本质上 深度睡眠脑电波会随着年龄而消退
with those deep sleep brainwaves that are diminished in aging,
而我们会跟这些脑电波同步“唱歌”
almost like a choir to a flagging lead vocalist.
就像一个唱诗班指挥着疲倦的主唱一样
By amplifying the size of those deep sleep brainwaves,
通过把深层睡眠的脑电波放大
we hope to try and salvage aspects of learning and memory function
我们希望挽回学习和记忆的脑功能
that sleep supports in older adults and those with dementia.
这也是睡眠可以为老年人及痴呆患者提供的功能
That’s one of my real hopes now.
这就是我目前的现实理想之一
And it’s one of the moonshot goals that we have.
也是我们如同登月梦的伟大理想之一
成年人需要的睡眠时间更短吗?

视频概述

孩提时代的我们几乎整天都在睡觉,少年时代的我们总是抱怨睡不饱,成年时代的我们逐渐改掉了赖床的习惯。睡眠时间似乎随着年纪增长而变短,步入老年的时候,我们真的不用睡那么久了吗?
