But a new study finds it can actually increase the amount of BPA in your system! Yet another reason to stop using it altogether!

但一個新的研究顯示，它還可能會增加酚甲烷進入你的體內的機會！這又是一個我們應該停止使用洗手液的原因！

Hey guys, Tara here for DNews - and there's been a lot of talk over the past few years about hand sanitizer, and why it can actually be dangerous for you.

嘿，大家好，這裡是 DNews 的 Tara，近幾年出現了許多有關乾洗手液，以及它可能對你有害的討論。

DNews actually did an episode on it just last year.

DNews 在去年還為此製作了一集節目。

The basic idea is that triclosan, the active ingredient in hand sanitizer, kills off all of your good bacteria, making it easier for antibiotic resistant strains to flourish.

主要的爭議來自於三氯沙(二氯苯氧氯酚)，它是洗手液中的活性成分，會殺死你身上的好菌，使得具抗藥性的菌株被篩選出來而可能大量增生。

But that's not the only reason it's bad. A new study published this week in PLOS One, finds that using hand sanitizer can also increase your skin's absorption of BPA.

但它有害的原因不僅是如此。在這星期 PLOS One 上的一篇新研究，發現使用乾洗手液會增加你的皮膚吸收 BPA 的量。

BPA stands for Bisphenol A, and it's a chemical used in the production of almost all hard plastics, including containers used for most foods and beverages.

BPA 就是酚甲烷，這種化學物質在幾乎所有種類的硬質塑膠中都有使用，包括大多數盛裝食物或飲料的容器。

Essentially, it imitates our hormones, in a way that disrupts our body's natural endocrine system.

基本上，它與我們的荷爾蒙十分相似，因此會擾亂我們體內正常的內分泌系統。

Studies have linked high amounts of BPA to hormone disorders, heart disease, cancer, infertility, and even diabetes.

研究顯示高濃度的 BPA 與荷爾蒙失調、心臟病、癌症、不孕以及糖尿病有關。

In a nutshell, it's bad. And according to this new study, hand sanitizer makes it even worse.

簡而言之，它是有害的。根據最新的研究，乾洗手液可能讓狀況更糟。

Most commonly used hand sanitizers contain chemicals that enhance the penetration of lipophilic compounds into your skin.

大多數常見的乾洗手液都包含了數種化學物質，使得親脂性化合物對你皮膚的穿透性增加。

BPA is one of those compounds.

BPA 也是這些親脂性化合物之一。

So researchers from the University of Missouri looked specifically at thermal receipt paper, which contains very high quantities of BPA to see if hand sanitizer increased the absorption of those chemicals.

因此， 密蘇里大學的研究者特別研究熱感應紙，這種紙常用作收據，且含有高量的 BPA，來研究乾洗手液是否會增加皮膚吸收熱感應紙上的化學物質。

Turns out, it does. A lot.

結果顯示：會，而且非常。

They found that using hand sanitizer before touching receipt paper, increases the absorption of BPA up to 100 fold.

他們發現在碰觸收據前使用乾洗手液的話，會提升 BPA 的吸收量一百倍。

What's more, is that all of that extra BPA lingers on your hands.

但還不只如此，你的手上仍然沾有許多 BPA。

So if you were to eat food directly afterwards, you'd be getting a double dose of BPA absorption - first from your hands, and then from your mouth.

因此如果你接著用手拿東西吃，你就會吸收到雙倍劑量的 BPA (先是從手的皮膚，然後從嘴進入體內)。

And those specific levels of BPA have been proven to increase the risk of disease in adults, and developmental abnormalities in children.

而特定劑量以上的 BPA 已經被證實會增加成人患病風險，並且造成兒童發育異常。

So what can we do about this?

那麼我們能做些什麼呢？

Well, unfortunately, no safe alternatives to BPA have been identified for use in thermal paper.

很不幸地，在製作這些熱感應紙時，我們仍沒有可以代替 BPA 的選項。

So until those technologies are developed, the best thing you can really do is just stop using hand sanitizer unless you really, really need it.

因此，在研發出替代品之前，你最好的選擇就是停止使用乾洗手液，除非你真的真的很需要它。

And definitely don't use it before ordering take-out food because that's not good.

另外，絕對不要在吃外帶食物之前使用乾洗手液，對你的身體不好。

What do you guys think? Have you sworn off hand sanitizer altogether?

那麼大家覺得如何呢？ 你們會乾脆完全不用乾洗手液嗎？
