Some people want more in some places and less in others.

有些人在一些地方想要更多，在另一些地方想要更少。

But overall humans are pretty invested in grooming our body hair.

但總的來說，人類對梳理體毛是相當投入的。

So what is body hair for?

那麼，體毛有什麼用？

Exactly?

確切地說？

And maybe you were told that removing your body hair makes you cleaner or healthier.

也許有人告訴你，去除體毛會使你更乾淨或更健康。

So let's find out if that's actually true on average were covered in about five million hair follicles.

是以，讓我們來看看這是否是真的，平均而言，我們被約500萬個毛囊所覆蓋。

That's around the same number as other non human primates are is just isn't as visible because most of it is that short soft peach bus that's called vela's hair and our fuss has a job.

這與其他非人類靈長類動物的數量差不多，只是沒有那麼明顯，因為大部分都是短小柔軟的桃紅色毛髮，這就是所謂的維拉的毛髮，我們的大驚小怪有工作。

It helps us regulate our temperature by helping us cool off when our sweat evaporates and when we're cold, minuscule muscles in our skin contract around those hairs and make them stand on end.

當我們的汗水蒸發時，它幫助我們調節體溫，當我們感到寒冷時，我們皮膚中的微小肌肉會收縮在這些毛髮周圍，使它們豎立起來。

That's what goose bumps are now.

這就是現在的雞皮疙瘩。

The longer coarser, more distinctive hair on our head, face, legs and groin is terminal hair.

在我們的頭部、面部、腿部和腹股溝的較長的粗糙的、有特色的毛髮是終端毛。

Terminal.

終端。

Here is what we tend to be a little more preoccupied with.

下面是我們往往更關注的內容。

Its found in specific places for a reason like your eyelashes and your eyebrows for example, keep sweat and debris out of your eyes with the added bonus of helping us express ourselves and recognize each other.

它出現在特定的地方是有原因的，例如你的睫毛和你的眉毛，使汗水和碎片不進入你的眼睛，還有幫助我們表達自己和識別對方的額外好處。

Terminal hair on the head, legs, chest and other large services also regulates our temperature and may protect our skin from UV damage and prickly pokey stuff in our environment.

頭部、腿部、胸部和其他大型服務的終端毛髮還可以調節我們的溫度，並可能保護我們的皮膚免受紫外線的傷害和環境中的刺癢的東西。

But also these are just our best guesses for why we have body hair in the places that we do because for evolutionary biology, body hair is actually still something of an enigma.

但這些也只是我們對為什麼我們在那些地方有體毛的最佳猜測，因為對於進化生物學來說，體毛實際上仍然是一個謎。

Now, pubic hair actually does have a really specific known job, but we'll get down into that a little bit more later.

現在，陰毛實際上確實有一個非常具體的已知工作，但我們稍後會更深入地瞭解。

Something else we do know is that hair growth is partially influenced by sex hormones and age.

我們還知道的是，頭髮的生長部分受到性激素和年齡的影響。

Some of it only appears once you hit puberty.

有些是在你進入青春期後才出現的。

So it's one of your secondary sex characteristics.

所以這是你的第二性徵之一。

Those are traits like breast development, facial hair, the beginning of menstruation and body composition changes.

這些特徵包括乳房發育、面部毛髮、月經開始和身體成分變化。

So almost like testosterone, which kind of fall in this family of androgens can affect the follicle to grow hair that's more coarse or thick.

是以，幾乎就像睪丸激素一樣，這種屬於雄性激素家族的東西可以影響毛囊，使其生長出更粗或更厚的頭髮。

People go through puberty, they start getting thicker hair in more androgen dependent areas whether it is armpit hair or pubic hair.

人們經歷了青春期，他們開始在更多依賴雄性激素的部位長出濃密的毛髮，無論是腋毛還是陰毛。

So your terminal hair is one external sign that internally you've rounded the corner into reproductive age, regardless of biology, it's obvious that we modern humans care a lot about what our body hair looks like, but why people have removed body hair for centuries for all kinds of sociocultural reasons.

是以，你的終端毛髮是一個外部標誌，在內部你已經繞到了生殖年齡，無論生物學如何，很明顯，我們現代人非常關心我們的體毛看起來像什麼，但為什麼幾個世紀以來，人們出於各種社會文化的原因而去除體毛。

But in modern hygiene history razors only really became popular for those who identify as women.

但在現代衛生史上，刮鬚刀只在那些被認定為女性的人中真正流行起來。

A little over 100 years ago when Gillette invented the first men's safety razor, they saw an opportunity to target an even broader client base.

100多年前，當吉列發明了第一款男士安全刮鬚刀時，他們看到了一個針對更廣泛客戶群的機會。

They started marketing campaigns that tide female body hair to shape and this was especially effective because the fashions of the day started to put lady's armpits on display and this made their product a razor now indispensable to self confidence and as hairless nous became more and more desirable, the consequences of hair removal also got more gruesome.

他們開始了營銷活動，將女性體毛的形狀作為一種趨勢，這特別有效，因為當時的時尚開始將女士的腋窩展示出來，這使得他們的產品--剃刀現在成為自信心不可或缺的東西，隨著無毛的小腹變得越來越受歡迎，脫毛的後果也變得更加可怕。

Like some hair removal creams of days past were made from rat poison.

像過去的一些脫毛膏是由老鼠藥製成的。

One method required the user to sit in front of an X ray and expose themselves to highly dangerous radiation for hours talking about beauty is pain plus some colors, textures and densities of body hair are deemed more socially acceptable than others.

有一種方法要求使用者坐在X射線前，將自己暴露在高度危險的輻射中數小時，談論美麗就是痛苦，再加上一些顏色、質地和密度的體毛被認為比其他體毛更容易被社會接受。

Like someone's gender or race or sexuality plays a role in the pressure they feel to remove or change their body hair.

就像某人的性別或種族或性取向在他們感受到的去除或改變體毛的壓力中起了作用。

And on top of that there is still the pervasive view that removing body hair is more hygienic, funnily enough, it can actually be the opposite.

除此之外，還有一種普遍存在的觀點，即去除體毛更衛生，有趣的是，它實際上可能是相反的。

I think that we're trying to fit like with these cultural norms, but a lot of times it ends up causing more problems.

我認為，我們正在努力適應這些文化規範，但很多時候它最終導致了更多的問題。

Now, any method of hair removal runs the risk of damaging your skin.

現在，任何脫毛的方法都有損害皮膚的風險。

You can open your hair follicles to the outside world can result in ingrown hairs and can introduce micro abrasions, all little portals through which microbes can enter and wreak havoc like infections staph.

你可以向外界開放你的毛囊，可以導致毛髮倒生，並可以引入微小的擦傷，所有的小門戶，微生物可以通過這些門戶進入並造成破壞，如感染葡萄球菌。

Anyone there are issues that can happen with waxing because you're really pulling on the hair, you're pulling on the skin at the same time when you're removing the wax and by pulling on the skin if you have sensitive skin and I mean it could potentially even cause tears in the skin and it's not just waxing like laser hair removal is becoming increasingly popular and is safer in terms of infection risk when compared to many at home methods.

任何人都有可能發生打蠟的問題，因為你真的是在拉扯頭髮，你在去除蠟的同時也在拉扯皮膚，通過拉扯皮膚，如果你有敏感的皮膚，我的意思是它甚至有可能導致皮膚撕裂，這不僅僅是打蠟，像脈衝光脫毛正變得越來越流行，與許多在家的方法相比，在感染風險方面更安全。

But that's only when it's performed by a certified professional because shady discount laser clinics are much more likely to cause skin damage or severe burns.

但這只是在由經過認證的專業人士進行的情況下，因為黑心的折扣脈衝光診所更有可能造成皮膚損傷或嚴重燒傷。

So when it comes to laser procedures expertise of the practitioner counts now many of us have probably felt particular pressure to alter our pubic hair but it's also the kind of hair removal we probably feel the least comfortable talking about.

是以，當涉及到脈衝光程序的從業人員的專業知識時，現在我們中的許多人可能已經感到特別的壓力，要改變我們的陰毛，但這也是我們可能感到最不舒服的一種脫毛的方式。

However you decide to do it removing hair down there can result in genital inflammation or long term changes to the skin.

無論你決定如何做，去除下面的毛髮可能導致生殖器發炎或皮膚的長期變化。

And according to some studies removing your pubic hair can also actually increase your risk of contracting some sexually transmitted infections.

而根據一些研究，去除陰毛實際上也會增加你感染一些性傳播疾病的風險。

Although on the bright side pubic lice are kind of going extinct I guess because of habitat destruction, our pubic hair protects us.

雖然從好的方面看，陰蝨有點要滅絕了，我猜是因為棲息地的破壞，我們的陰毛保護了我們。

It minimizes damage caused by friction.

它最大限度地減少了由摩擦引起的損害。

It helps keep out the bad microbes that can cause U.

它有助於阻擋可能導致U的不良微生物。

And other infections and once again it keeps everything the right temperature.

還有其他感染，並再次使一切保持合適的溫度。

So I'm on team leave your hair alone.

所以我加入了 "別管你的頭髮 "團隊。

But of course there's a huge cultural aspect to you know to body hair and not having it.

但是，當然有一個巨大的文化方面，你知道體毛和沒有體毛。

So so I get it but I would love to help kind of shake up that idea a little bit and really, you know, make it normal to have body hair.

所以，我明白了，但我很想幫助撼動一下這種想法，真的，你知道，讓有體毛成為正常的。

It's all normal natural and part of vegan a mammal babe, you don't need to remove it unless you have a really good reason to that.

這都是正常的自然現象，也是素食者的一部分，寶貝，你不需要去除它，除非你有一個非常好的理由來這樣做。

Really good reason can be some kind of medical conditions where removing hair is part of treatment, but it can also be just because you want to.

真正好的理由可能是某種醫療條件，脫毛是治療的一部分，但也可能只是因為你想脫。

So if you do landscape, here's some ways to do it safely.

是以，如果你做景觀，這裡有一些安全的方法。

So a big thing, changing out your razor blade regularly at least once every two weeks or every 7 to 8 shades when you store your razor, make sure it's facing up when it's facing down.

是以，一件大事，定期更換你的刮鬚刀片，至少每兩週一次，或每7至8個陰影，當你儲存你的刮鬚刀時，確保它朝上時，它朝下。

There's a higher chance for to rust.

有更高的機會生鏽。

And then I do think that it is helpful to exfoliate regularly because a huge cause of ingrown hairs is the build up of skin over the hair follicle and that traps the hair.

然後我認為定期去角質是有幫助的，因為毛髮倒生的一個重要原因是皮膚在毛囊上的堆積，這使毛髮受困。

In words, I'm going to be honest, I didn't know most of these until my early twenties.

話說回來，我實話實說，我在二十出頭的時候才知道其中大部分。

And another big one is to use a separate razor for your genitals.

而另一個大問題是為你的生殖器使用單獨的剃刀。

And the microbiologist in me is begging you to avoid high infection risk scenarios like maybe don't go in a hot tub if you recently accidentally nicked your leg shaving and just know what we think our bodies should look and act like.

而我這個微生物學家則懇請你避免高感染風險的情況，比如如果你最近刮鬍子時不小心劃傷了腿，也許就不要去泡熱水澡了，只要知道我們認為我們的身體應該是什麼樣子就可以了。

Often doesn't have its roots in science or medicine, you are not gross or dirty if you decide to skip the shape, it's just a choice like any other one we make in the modern cosmetic world.

往往沒有科學或醫學的根源，如果你決定跳過這個形狀，你並不噁心或骯髒，它只是一個選擇，就像我們在現代美容世界中的任何其他選擇。

And now, armed with more information, you get to decide what works best for you and your follicles.

現在，有了更多的資訊，你可以決定什麼是最適合你和你的卵泡。
