为何有人鼾声如雷?

Why do some people snore so loudly? - Alayna Vaughan

“听 他呼吸可真费劲儿” 威廉•莎士比亚《亨利四世》第一部
A leather mask that clamps the mouth shut.
夹住嘴的皮面具
A cannonball sewn into a soldier’s uniform.
缝在士兵衣服里的炮弹
And a machine that delivers sudden electrical pulses.
一种能突然发出电脉冲的机器
These old items were all intended treatments
这些古老的物品都是为了解决
for a problem that has haunted humanity for millennia: snoring.
困扰人类数千年的问题:打鼾
It might seem harmless,
打鼾看上去毫无危害
but snoring can be a sign of something more dangerous.
但却是某些更危险事情的信号
So, what exactly causes snoring?
那么 到底是什么引起打鼾的呢
And when does it become a problem?
它又是从什么时候起成为麻烦事儿的呢
A snore’s quality can range from a gentle mew to a stuttering chainsaw—
鼾声可以是轻柔的喵喵声 也可以是断断续续的电锯声
but all snores originate from the respiratory tract,
但所有的鼾声
which is lined with soft tissues.
都来自布满软组织的呼吸道
During sleep, the muscles around these tissues relax,
睡觉时 软组织周围的肌肉会松弛下来
narrowing the airway.
进而挤压呼吸道
Many factors, including congestion, anatomical features,
很多因素 包括呼吸道充血 人体解剖学特征
and the position you’re sleeping in,
以及你睡觉的姿势
can further constrict this passage and lead to or exacerbate snoring.
会进一步压缩呼吸道并导致或加重打鼾
The narrower the respiratory tract is, the stronger the airflow,
呼吸道越窄 呼吸就越急促
and the more those relaxed tissues may vibrate,
放松的组织也会振动得越厉害
producing sound.
从而制造声响
Most of us will snore at some point in our lives.
生命中的某个时候 我们大多都会打鼾
But loud, chronic snoring is one sign of a sleep disorder
但响亮而长期的鼾声却是睡眠障碍的信号
known as obstructive sleep apnea.
这被称作“阻塞性睡眠呼吸暂停”
It affects about a quarter of all adults,
它影响着大约四分之一的成年人
but it’s estimated that around 80% of people who suffer from it aren’t aware they have it.
但估计其中约80%的人没有意识到这一点
This is especially troublesome because it can lead to serious cardiovascular issues.
这就更糟了 因为它会导致严重的心血管问题
Obstructive sleep apnea is usually caused by blockages in the airway
“阻塞性睡眠呼吸暂停”通常由气管阻塞引起
and is mainly characterized by pauses in breathing during sleep.
主要表现为 睡眠时呼吸暂停
There’s one other kind of sleep apnea called central sleep apnea,
还有种睡眠呼吸暂停叫“中枢睡眠呼吸暂停”
which occurs when the brain temporarily fails to regulate the body’s breathing.
会在大脑暂时无法调节身体的呼吸时发生
This condition isn’t as common,
这种状况与前者相比并不常见
and snoring is usually a less prominent feature—
且打鼾也往往不是它的显著特征——
though you can have both.
尽管这两种呼吸暂停可能会同时存在
If you’re experiencing obstructive sleep apnea,
如果你正经历着阻塞性睡眠呼吸暂停
you might stop breathing for 10 or more seconds before waking,
你可能会在醒来前停止呼吸10秒或更久
sometimes without realizing it, to catch your breath.
有时 你还没意识到 就又呼吸正常了
In doing so, you might make a snorting or a choking sound.
这时 你可能会发出喷气声或哽咽声
This may happen five times an hour,
这种情况 一小时可能会出现五次
though in severe cases, it could occur more than 30.
而在严重的情况下 可能会超过三十次
And it’s a problem because your tissues are getting less oxygen.
同时 这也是个问题 因为你的组织得到的氧气越来越少
As you experience periods of low oxygen intake,
当氧气摄入量变低时
your body releases stress hormones.
你的身体会释放压力荷尔蒙
And your blood vessels constrict to get oxygenated blood to your vital organs.
同时血管收缩 以将含氧血输送到重要器官
This increases your blood pressure and puts additional stress on your heart.
这会增加你的血压并对心脏施加额外压力
And this is why obstructive sleep apnea can be linked to hypertension
这就是“阻塞性睡眠呼吸暂停”与高血压
and other cardiovascular problems.
以及其他心血管疾病相关的原因
Your difficulty breathing and poor-quality rest may also lead to headaches,
呼吸困难和睡眠质量差也可能导致头痛
decreased concentration, and chronic fatigue.
注意力下降 慢性疲劳
So what puts someone at risk of developing obstructive sleep apnea?
那么 是什么让人有患上阻塞性睡眠呼吸暂停的风险?
Features like larger tongues, thicker necks, and smaller jaws
诸如较大的舌头 较粗的脖子及较窄的下巴这些特征
can make people more susceptible.
都让人易受影响
Older people are more at risk because, as we age,
年龄偏大则风险更大 因为随着年龄的增长
our soft tissues loosen, further narrowing our airways.
我们的软组织会变松 气管会进一步变窄
Drinking alcohol before going to sleep can cause
睡前饮酒
excessive relaxation of our throat and jaw muscles.
会导致我们的喉及下巴肌肉过度放松
And one of the main contributors to obstructive sleep apnea is weight gain
而导致阻塞性睡眠呼吸暂停的一个主因是体重增加
because more tissue around the neck can constrict the airway.
因为颈部周围更多的组织会抑制呼吸道
Many researchers see weight loss as a solution to obstructive sleep apnea.
很多研究人员视减肥为阻塞性睡眠呼吸暂停的解决方法
Certain behavioral shifts, like limiting your alcohol consumption before bed,
某些行为上的改变 比如睡前限制饮酒
elevating your head, and avoiding sleeping on your back may also help.
垫高头部 以及避免仰卧着睡都可能有用
For people who have a milder condition,
对于病情较轻的人来说
mouth and throat exercises have been shown to alleviate obstructive sleep apnea
在一些初步实验中 口腔和喉部锻炼已经被证明
in some preliminary trials.
可以缓解阻塞性睡眠呼吸暂停
But these approaches, and devices like oral appliances,
但这些方法 以及口腔器材等设备
may not always be sufficient.
可能也还不够
Sleep apnea can be reliably treated using CPAP machines,
呼吸机是治疗睡眠呼吸暂停的可靠手段
which keep the airway open by delivering a constant stream of pressurized air.
它通过源源不断地输送加压空气来保持呼吸道畅通
Doctors will usually aim to remedy sleep apnea
医生通常会先使用非侵入性疗法
with non-invasive treatments like these first,
来治疗睡眠呼吸暂停 比如这些
but if they don’t work, they may consider surgery.
但若没用的话 他们可能会考虑外科手术
Snores can be silly.
打鼾看上去很傻
But intense ones are well-worth investigating with a doctor.
但严重的打鼾很需要医生好好看看
After all, everyone needs a chance to catch their breath—
毕竟 每个人都需要“一个喘息的机会”
and some z’s…
并睡个好觉
sleep apnea is just one disorder that messes with of the quality of your sleep.
睡眠呼吸暂停只是影响睡眠质量的一种障碍
Find out how you can break the cycle of insomnia with this video,
通过这个视频的学习 你可以打破失眠的恶性循环
or dive into the creepy fear inducing disorder,
或深入了解令人毛骨悚然的恐惧诱导障碍
known as sleep paralysis with This video.
即“睡眠瘫痪症”
