  • Hi I’m Craig, my grandmother was half mosquito, and this is Mental Floss on YouTube.

    嗨,我是克雷格,我的祖母是半個印地安人(音同蚊子),這裡是「 Mental Floss」的頻道。

  • Today, I’m going to answer locked-up time lady’s BIG question.

    今天我要回答來自「時光越獄小姐」的大疑惑,

  • " Why do mosquitoes prefer biting some people to others? "

    「為什麼蚊子總愛叮某些人?」

  • " Is there something we can avoid doing or do besides using repellent like eat bananas?"

    「除了使用驅蚊用品之外,可以做什麼措施來預防被蚊子叮,例如吃香蕉?」

  • Well, time lady, youre right that mosquitoes have preferences.

    這麼說,這位時光小姐,妳對於蚊子有偏好的觀點是正確的。

  • 10-20% of people happen to get bit more than others.

    有 10-20% 的人確實比其他人更容易被叮。

  • And there are a few possible reasons for this, which I’m going to tell you about today.

    下面幾個可能的原因,就是我今天要和妳解釋的。

  • Let’s get started!

    我們開始吧!

  • Experts estimate that around 85% of the reason that mosquitoes prefer YOU is genetic, so youre pretty much born with it.

    專家估計,約 85% 的原因在於「你」的基因,所以這幾乎是天註定的。

  • It's not your good looks, sorry about that.

    很抱歉這不是因為你長的多好看。

  • Mosquitoes will especially come after you if you have the perfect combination of genetics and scent.

    如果你擁有的基因和氣味,符合蚊子的胃,牠就會來了。

  • Bon appétit.

    好好享用。

  • There’s also stuff on your skin that attracts them.

    皮膚表層也會有吸引蚊子的因子。

  • Youll probably suffer more bites if you happen to produce more lactic acid, which comes from your sweat glands.

    如果你汗腺分泌發達,皮膚表面產生較多乳酸,你可能會被叮更多包。

  • And in 1999, it was observed that mosquitoes who carry malaria are most attracted to sweat that had been sitting on skin for a day or two, rather than fresh sweat.

    在 1999 年,就發現皮膚上有殘留一至兩天汗液的人,會比剛出汗的皮膚更容易吸引瘧疾病媒蚊。

  • Theyll also prefer you if you have more of THESE bacteria living on your skin.

    蚊子也比較愛皮膚上葡萄球菌、貪食菌量高的人。

  • People who have more of THESE will have less mosquitoes to worry about.

    若身上有較多假單孢菌、纖毛菌、代夫特菌、放線菌,則不太會被叮。

  • Blood type might have something to do with it, too.

    血型也可能會影響。

  • A 2004 study found that mosquitoes were twice as likely to land on people who were Type O rather than Type B.

    一項 2004 年的研究發現,蚊子停在 O 型的人身上的機率,是 B 型人的兩倍。

  • Boy, it would SUCK to be part of that study.

    若你有參與這項研究的話,就知道有多惱人。

  • Type A was even less popular than Type B.

    A 型血也沒有 B 型來的受蚊子歡迎。

  • Plus, around 85% of us have a chemical on our skin that reveals our blood type.

    此外,約 85% 人類的皮膚上擁有某種可以判斷血型的化學物質。

  • Mosquitoes go after those 85% of people more than the 15% who don’t secrete the chemical.

    蚊子也傾向叮有分泌化學物質的人那 85% 的人,而非那 15%。

  • People who produce more carbon dioxide when they exhale are also more likely to get bit.

    呼吸時排放較多二氧化碳的人,也更容易被叮咬。

  • A mosquito can smell this, so itll go after them.

    蚊子能感受得到,所以才會去叮他們。

  • Larger people and pregnant women suffer most for this.

    體型較大或懷孕的女性,經常是深受其害的目標。

  • Another interesting group that happens to get bit more often is beer-drinkers.

    另一個也容易被蚊子叮的有趣的族群,就是愛喝啤酒的人,

  • This might be related to carbon dioxide production as well -- people tend to breathe harder after drinking a beer.

    可能在於排放較多的二氧化碳,因為人在喝酒後,呼吸會比較費力。

  • Or, they might be a little warmer and nicer to land on.

    或者,皮膚比平常溫熱,而適合蚊子停留。

  • In your question, you mentioned that eating bananas might help get the mosquitoes go away.

    針對你的提問,你提到吃香蕉可以讓蚊子遠離自己。

  • That’s actually a myth.

    這只是個迷思。

  • Vitamin B-12 won’t work either.

    維他命 B-12 也一樣沒有效用。

  • Experts pretty much recommend your standard old fashioned bug spray.

    專家建議使用傳統的防蚊液。

  • But, some work better than others.

    但有些防蚊液特別有用。

  • Ideally, you should use an insect repellent with around 24% of the chemical DEET.

    理論上來說,你應該使用有 24% 防蚊胺的防蚊液。

  • As usual, it's all in the DEETails. I'm sorry, I'm really sorry about that.

    這些成分往往都寫在那些「避蚊案」了,抱歉這笑話有點冷。

  • Thanks for watching Mental Floss on YouTube, made with the help of these lovely skeeters.
