为何我们的汗水不好闻?
Why Does Sweat Smell So Bad?
为何我们的汗水不好闻?
Our bodies have two main kinds of sweat glands. The sweat glands that are distributed over most of the body produce an innocent, clear sweat that’s more than ninety-nine percent water. As this watery sweat rinses your skin, it cools the body by evaporation–and even performs a community service by rinsing away potentially stinky bacteria!
我们的身体主要有两种汗腺。一种汗腺几乎遍布全身，其流出的汗水是干净无味的，含水量超过99%。当这种汗水冲洗你的皮肤时，它通过蒸发作用给你的身体降温，甚至有时候还扮演“义务清洁员”的角色，将你皮肤表面的有害细菌清洗掉。
But there’s another type of sweat gland located only in the armpits, groin, and around the nipples. These sweat glands produce a thicker, cloudier sweat that’s a favorite food of certain bacteria. And once these sweat-loving bacteria really start chowing down, they make the smell of the sweat on these parts of the body even stronger. That’s why the longer you’re sweaty, the stinkier you get.
但是人体内还存在另一种汗腺，它分布在腋窝、腹股沟和乳头附近。这种汗腺会产生大量粘稠的汗水，这些汗水还是某些细菌的美食。当喜好汗水的细菌在享受它们的美食时，这些部位的汗水的气味会变得更重。这就是为什么你出汗的时间越长，你身上的汗臭味越重的原因。
Like the first type of sweat glands which cool and cleanse the body, these stinkier sweat glands also have an evolutionary function. For other mammals, this potent sweat speaks volumes about an individual’s identity and level of sexual interest. But does it still serve the same social purpose for humans? In fact, there is some evidence that it does.
就像第一种汗腺有清爽和清洁人体的功能一样，这种粘稠的汗液在进化史上也有它的作用。对于其它的哺乳类动物来说，浓重的汗水味可以代表它的个体身份和性魅力指数。但是这种社交手段在人类身上还适用吗?事实上有证据显示，一切皆有可能!
为什么会形成黑眼圈
Why Do Dark Circles Form Under My Eyes?
为什么会形成黑眼圈
It’s eleven o’clock Sunday morning, and you’ve just woken up after a late night of carousing. You stumble out of bed, brace yourself on the bathroom sink and blink into the mirror.
现在是周日上午11点，而你刚从前一晚的狂欢过后醒来。你跌跌撞撞地走下床，双手撑在盥洗台上，睡眼惺忪地看向镜子。
There, under your eyes, are dark, puffy patches that make you look like an NFL linebacker. I need more sleep, you think, fingering the dark spots. And so you stumble back to bed.
看到了吗，你眼睛下面那深色浮肿的眼袋，让你看起来像美国橄榄球联盟的后卫队员。用手抚摸着黑眼袋，你想，我需要更多的睡眠。于是你又踉跄着回到床上。
Do I Need More Sleep?
我需要更多睡眠吗?
You may indeed need to sleep a bit longer, but despite the common misconception, dark circles and puffiness under or around your eyes appear to have little to do with lack of sleep.
也许你的确需要多睡一会儿，尽管有着普遍的误解，但眼周或眼底的黑眼圈和浮肿似乎与睡眠不足没有太大的关系。
In fact, what seems to be a fairly common and hence supposedly explainable phenomenon remains something of a mystery to scientists.
事实上，这个看起来相当容易解释的常见现象对科学家们来说却仍然是个谜。
Mystery
谜题
What scientists do know is that the skin under the eyes is very thin and sensitive. When for a variety of reasons blood and other fluids accumulate in the area under your eyes, the delicacy of the skin makes the fluid’s color partly visible. This is what appears to account for the dark patches.
科学家们所知道的是，眼底的皮肤非常薄，非常敏感。当由于种种原因，血液和其他液体在眼底部位积聚时，这层细腻的皮肤就会使得液体的颜色浮现出来。这似乎才是黑眼圈形成的原因。
Allergies may also be to blame. An allergic reaction can cause cells under the skin of the eyes to release histamine, a chemical that causes fluid accumulation and swelling. This is what appears to cause puffy eyes.
过敏也是可能的原因之一。过敏反应导致眼底皮肤细胞释放出组胺，这种化学物质会引起积液和皮肤肿胀。这似乎才是眼袋形成的原因。
And finally, there is heredity. Do your parents have dark circles under their eyes? If so, you may have found the source for your own dark circles.
最后还有遗传因素的影响。你的父母是否有黑眼圈?如果有，也许你就能够找到你有黑眼圈的原因
