空气有多脏 鼻毛就有多长？ How dirty air nose hair is long?

网上，一张各地鼻毛地图很火爆 不过，专家说鼻毛只能防大颗料 online,A nose hair all over the map hot but,Experts say nose hair can prevent big makings

你可能会注意自己有多长的头发，可你知道自己需要多长的鼻毛吗？ You may pay attention to how much he long hair,But you know you need more long nose hair?

　　前几天，在微博上，这张图就颇为火爆。一位网友PS了一张照片，并标注，“在南京，你需要这么长的鼻毛”。

A few days ago,In micro blog,This picture is rather hot.A net friend PS a picture,And mark,"In nanjing,You need such a long nose hair".

　　金陵晚报记者经过搜索发现，这其实来源于一个环保项目。在这个专题页面中，你选择不同的城市，它就以鼻毛的长度来提示你，城市的空气状况如何，你又需要多长的鼻毛才能抵抗。

Jinling evening news reporters after searching,It comes from an environmental project.In this special page,You choose a different city,It is with the length of the nose hair to prompt you,City's air status,You also need more long nose hair to resist.

　　记者也点选了不同城市，其中显示南京人所需的鼻毛长度在中国各大城市里居中等水平，上海人所需要的鼻毛长度稍短，旅游城市厦门对应的鼻毛长度更短，而兰州人所需要的鼻毛长度就明显长出一大截。总体来说，北方人比南方人更需要长长的鼻毛。

Reporters also click on the different city,Which shows that the nanjing nose hair length in all major cities in China, such as the central level,Shanghai need nose hair length slightly shorter,Tourist city xiamen corresponding nose hair length shorter,And lanzhou people need nose hair length was obviously grow a large margin.In general,The north from the south more than need long nose hair.

　　“鼻毛长度”VS“空气质量”，这结果可谓一目了然。不过我们也想知道，真的是空气有多脏，鼻毛要多长吗？是不是为了身体的健康，我们不一定要蓄一头飘逸的长发，却必须养一丛茂盛的鼻毛？

"Nose hair length"vs"Air quality",This result is be clear at a glance.But we also want to know,Really is how dirty air,Nose hair to long?Not for the health of the body,We don't have to be a head storage elegant long hair,But must have a bundle of lush nose hair?

鼻毛能够长多长？ 看眉毛长度能揣测大概 How long can the long nose hair? See eyebrows length can probably guess

　　鼻毛大概是我们人体上生长位置最隐蔽的毛发之一，偶尔我们也会见到鼻毛偷偷伸出鼻孔，这时为了避免尴尬，我们一定会加以修剪整理。不过，要是不做任何处理，鼻毛到底能长多长？能不能和图片上一样夸张，实现“古有美髯公，今有长鼻毛”的效果？

Nose hair is probably we grow on human body position the most hidden one of the hair,Occasionally we also see the vibrissae secretly out of his nostrils,At this time in order to avoid embarrassment,We will be trimming.but,If you don't do any treatment,How long can the long nose hair?Can you picture and the hyperbole,realize"Ancient have beautiful hige and,This is long nose hair"effect?

　　“这不太可能。”南京鼓楼医院皮肤科专家包军说，我们也见过有些人鼻毛旺盛，从鼻孔里探出头来，但大多数人即便不修剪，鼻毛也长不出来。这是因为鼻毛的寿命很短，一根鼻毛尚未长得太长，就已经自然脱落了。“一般来说，头发的生长周期可以是几年，而鼻毛只能活几个月。”

"It's not very likely."Nanjing gulou hospital dermatological department experts BaoJun said,We have seen some people nose hair exuberant,From the unearthed in the nostrils,But most people even if not trim,Nose hair will grow out.This is because the life of nose hair is very short,A piece of nose hair not grow too long,Have a fall off naturally."Generally speaking,Hair growth cycle can be a few years,And nose hair can live only a few months."

　　不过，凡事总有例外。包军说，有一种人眉毛生长特别旺盛、又粗又长，还有人管这种眉毛叫“寿眉”。“这种眉毛是不是主长寿不能乱说，但拥有这样一幅浓眉的人，往往鼻毛生命力也会比较强，而这源于两者的调控基因。”因为调控基因相同，所以眉毛旺盛，鼻毛也不会短；我们经常见到一些老先生，顶着浓眉，鼻毛也从鼻孔里偷偷探头，就是这个道理。

but,There should always be exceptions.BaoJun said,There is a person special eyebrows grow strong/Big and long,Others tube this eyebrow call"Life eyebrow"."The eyebrows are main longevity can't blather,But such a picture of thick eyebrows,Often nose hair vitality will also stronger,This comes from the regulation of gene."Because of the same gene regulation,So the brow strong,Nose hair also not short;We often see some old man,Top with thick eyebrows,Nose hair from the nostrils secretly probe,That is the reason why.

　　除了看眉毛的长度，眉毛的粗细、硬度也很有讲究，同样可能暗示了鼻毛的生命力。“一般来说，毛发越粗、越硬，就能生长越久；相反，细软的头发就容易折断、脱落，即便养长了也容易分叉。其他部位的体毛往往也是如此。如果眉毛又粗又硬，这样的人鼻毛也会比较能长。”

In addition to see the length of the eyebrows,Eyebrows weight/Hardness is also has exquisite,The same may indicate the vitality of nose hair."Generally speaking,Hair thicker/More hard,Can grow more long;instead,Soft hair is easy to break/off,Even if a long also easy to branch.Other parts of the body and so often.If the eyebrows, thick and hard,Such people nose hair will also more long."

鼻毛越长越防脏？ 它只能防一些大颗粒 Nose hair more long more prevent dirty? It can prevent some large particles

　　南京鼓楼医院呼吸科专家肖永龙告诉记者，当空气被吸入我们的鼻腔，要经历重重关卡。“首先，鼻腔的结构是弯弯曲曲的，而不是一条大路直通肺部。这就是为了让空气在里面绕来绕去，这个过程中，空气中的一些脏东西就会慢慢沉积下来，而不会钻入下呼吸道深处。有些脏东西还会撞上黏膜，而黏膜上会有许多自然分泌物，这些分泌物会把一些有害微生物和污染颗粒黏住、包裹起来，然后排出体外。”

Nanjing gulou hospital respiratory medicine experts XiaoYongLong told reporters,When the air is inhaled our nasal cavity,To experience many hurdles."First of all,The structure of the nasal cavity is the crooked,Instead of a road through the lungs.This is in order to let air in walking around,The process,Some of the air dirty things will slowly deposit down,And won't go deep in the lower respiratory tract.Some dirty things will run into mucous membrane,And there are many natural secretion on mucosa,The secretion will put some harmful organisms and pollution stick particles/Parcel up,And then discharge in vitro."

　　在这个过程中，鼻毛也是重要的一道屏障，也可能是第一道屏障。“鼻毛主要是起一个筛子过滤的作用。比如有一只小飞虫突然钻进鼻孔，这时候鼻毛就会起到一个阻挡作用，避免它闯入呼吸道深处；同时在这一刺激下，我们会打喷嚏把这些异物给清除出来，从而保护我们的呼吸道。”

In this process,Nose hair is also important barrier,May is the first barrier."Nose hair is mainly up a sieve filtration effect.Such as have a little fly suddenly drilling nostrils,Nose hair at this time will have a barrier function,Avoid it into the depths of the respiratory tract;At the same time in the stimulation,We will sneeze these foreign body to clear out,In order to protect our respiratory tract."

　　不过，鼻毛的屏障作用也没有想象中那么强。“其实鼻毛主要能抵挡的还是一些比较大的东西，像是小飞虫，或者一些大颗粒，真正肉眼不可见的有害微生物与污染颗粒，靠鼻毛是无法阻挡的。”肖永龙说，这主要是由于鼻毛的密度并不高，对于那些肉眼不可见的细微物质缺乏阻挡能力，所以充其量只能算是“初筛”。而且鼻毛的屏障能力和长度无关，即便有长鼻毛也不能更加有效地阻挡污染物。

but,The barrier of nose hair effect also have no imagination in so strong."In fact vibrissae main can resist or some bigger things,Like small fly,Or some big particles,Really invisible harmful organisms and pollution particles,On the nose hair is unstoppable."XiaoYongLong said,This is mainly due to the nose hair density is not high,For those invisible fine material lack of blocking ability,So at best can be"Initial screen".And the barrier of nose hair length of ability and independent,Even if has a long nose hair can more effectively stop pollutants.

　　当然，鼻毛还是很重要的，除了阻挡一些空气中的有害物外，它还可以保持鼻黏膜的温度与湿度，同时保护嗅神经。这些虽不能对抗空气污染，但对于鼻腔还是有保护作用的。“这个图片虽然可以形象提示你当前空气质量，但鼻毛再长也不能帮你完全隔离污染。”

Of course,Nose hair is very important,In addition to stop some of the harmful air sighted,It also can keep temperature and humidity of the nasal mucosa,At the same time protect olfactory nerve.Although these can't fight against air pollution,But for nasal or have protection."This picture may image tip your current air quality,But nose hair long again can't help you to completely isolate the pollution."

除了鼻毛还有啥？了解呼吸道的全套防线 In addition to nose hair and what?To understand the complete line of respiratory tract

　　南京鼓楼医院呼吸科专家戴令娟告诉记者，我们的呼吸道有一全套完善的防御功能，帮助我们最大限度逃过空气中的诸多有害物质，我们也很有必要了解一下。

Nanjing gulou hospital respiratory medicine experts to wear make Juan told reporters,We have a full set of respiratory tract of the perfect defense function,Help us maximum escaped many harmful substances in the air,We also is necessary to know about.

　　鼻毛：刚刚已经说了，鼻毛就像一道初级防线，可以阻挡一些体积较大的杂质，避免它们深入呼吸道。

Nose hair:I've already said,Nose hair like a primary defence,Can stop some large impurity,Avoid them into the respiratory tract.

　　黏液：虽然鼻涕很恶心，但说句实话，它帮了你不少忙。因为它会把空气中大量的有害物质黏住、包裹好，然后找机会排出体外，这其中就包括不少病毒。知道为什么鼻腔干燥容易感冒吗？其实也有这方面的因素起作用。

mucous:Although the nose is very sick,But to be honest,It helps you a lot of busy.Because it will take a lot of harmful substances in the air stick/parcels,Then for a chance to discharge in vitro,That includes a lot of virus.Know why nasal dry easy to catch a cold?In fact also have this factors play a role.

　　黏膜：呼吸道黏膜本身就是一道屏障，而它分泌的黏液会提高它的保护能力。

mucosa:The respiratory tract mucosa itself is a barrier,And it will improve the secretion of mucous its protection ability.

　　鼻甲：我们的鼻甲结构很复杂，内在曲折繁复，这是为了避免脏东西长驱直入。只要在这个弯弯绕的过程中，那些脏东西不小心撞上黏膜，就会被捉住处理掉。

turbinate:Our turbinate structure is very complicated,And heavy and complicated inner,This is to avoid dirt march into.As long as in the WanWanRao process,Those dirty things accidentally hit mucosa,Will be taken get rid of.

　　纤毛：我们的下呼吸道黏膜同样有屏障作用，而这些器官中的纤毛和鼻毛作用有些相似。但纤毛顾名思义，体型更小。要注意，有些有害物质比如香烟，会让纤毛摆动能力下降，从而削弱呼吸道的清除防御功能。

cilia:Our lower respiratory tract mucous membrane barrier function is the same,And these organs of cilia and nose hair some similar role.But ciliated just as its name implies,Size smaller.Attention should be paid to,Some of the harmful material such as cigarette,Will let cilium swings ability to drop,Thus weakening the respiratory removal defense function.

　　吞噬细胞：在我们的肺泡里，吞噬细胞会作为最后的防线，吞噬掉那些入侵人体的异物，将其清除，从而起到保护作用。(通讯员 张可欣 南京师范大学实习生 匡郁华 金陵晚报记者 朱菁菁 报道)
