12則每個人一定都好奇過「但不好意思問出口」的爆笑害羞疑問！

1. 可以在泳池裡尿尿嗎？   有些人認為如果在泳池裡尿尿的話，尿液和泳池裡的氯接觸會製造出類似催淚瓦斯的氯化氫。但其實要產生這種化學反應、泳池裡的氯含量應該要多到足以溶掉人們的皮膚才行，所以尿尿在泳池裡是安全的。(等等，要尿尿去廁所尿啦！)   2. 把屁憋住會

1. 可以在泳池裡尿尿嗎？

Everyone has embarrassing questions that they google to avoid asking out loud. But don’t worry, science has come to the rescue with some answers. People once believed if you peed in the pool that it would create a toxic chemical called cyanogen chloride, which is similar to tear gas. The amount of chlorine needed for this reaction would probably melt your skin, so it’s safe to say you can pee in the pool. Still, I’m not saying you should.

2. 把屁憋住會對身體造成影響嗎？

Everyone has held in some gas now and again, but can it do damage to you? Holding in a fart can cause bloating and other uncomfortable symptoms, but worst of all it can cause hemorrhoids or even a distended bowel. But don't worry, because you'll release the gas as soon as you fall asleep before any of these things occur.
 
每個人應該都有憋屁的經驗吧？(尤其在電梯裡) 憋屁的確會造成浮腫及其他讓你不舒服的症狀，嚴重甚至會造成痔瘡或腸阻塞！但睡覺時例外，這時候人體內的屁會自己排掉，所以不用擔心睡到一半得痔瘡啦！

3. 為什麼暈眩的時候會想吐？

Your brain makes you throw up because it thinks it's being poisoned. When you throw up there are three main reasons why: irritation of your brain, irritation of your stomach, or irritation of your hormones. Your brain gets irritated when the fluid in your brain and your inner ears are different and might eject your stomach's contents.
 
你的大腦之所以會讓你想吐，是因為它覺得身體被下毒了。通常你會吐是因為3種原因：腦部、胃部或賀爾蒙受到刺激。當你的腦內液體與你的內耳不平衡時，你的大腦會受到刺激，進而讓你想將胃容物排出。

 

4. 為什麼頭髮會變白？

Your hair actually has no color to it at all. Hair color depends on pigment secretion and this is why it might change over time. When your body ages, it slowly stops producing the pigment and the hair returns to its natural state. Some people’s bodies stop producing the pigment sooner than others.
 
其實頭髮是沒有顏色的。頭髮的顏色取決於色素的分泌，所以顏色會隨著時間改變。當身體開始老化時，色素的產生就會開始減少、而頭髮的色素便會開始褪去並恢復到原本的樣子。因為體質不同，有些人會比其他人更早開始停止產生色素。

5. 為什麼會宿醉？

Well, that’s because you consumed a shit-ton of alcohol. When you drink alcohol it makes you pee more and in turn dehydrates you. Along with that, alcohol slows down the rate that the stomach empties itself and increases production of stomach acids, which can lead to nausea. Drinking also causes blood vessels to dilate producing that pounding headache.
 
嗯，首先呢那是因為你喝了太多酒了！喝酒會讓你頻尿，所以你的身體會開始缺水。喝太多酒也會讓你的心跳變慢，而酒精刺激胃產生更多胃酸、便會讓你覺得噁心想吐。喝酒也會讓你的血管膨漲，因此讓你覺得頭痛欲裂。

6. 為什麼男生早上會「一柱擎天」？

Morning wood, scientifically known as nocturnal penile tumescence, serves to stretch out the two sponge-like areas that cause erections. For healthy men it is natural to have this happen 3-5 times a night.
 
這現象在科學上稱為「夜間陰莖勃起 (Nocturnal Penile Tumescence)」，是2個主要造成勃起的海綿體伸展所導致，具體發生的原因仍無從得知，但對一位健康的男性來說，一晚發生3-5次是正常的。

 

7. 為什麼鼻塞時，都只有一邊會塞住？

Your two nostrils are a team that work together to help you breathe, but they split the workload. Even when you’re not sick, one nostril is doing more work than the other. Your autonomic nervous system, which takes care of things you don’t consciously control, will switch this for you.
 
你的2個鼻孔是幫助你呼吸的一個團隊，所以它們是採取分工合作的方式。就算沒生病時、同時間內其中一邊鼻孔的工作量還是會比另一邊重。你的自主神經系統，也就是替你無意識控制許多事的構造，會幫你自動調整鼻孔的工作量。

 

8. 可以在海裡尿尿嗎？

Urine is 95 percent water with sodium and chloride ions. But urine contains something the ocean does not; urea. Urea is a water-soluble organic compound that helps the body rid itself of nitrogen. When urine and ocean water combine, the nitrogen in urea produces ammonium and acts as food for the ocean’s plant life. So go for it.
 
尿液是由95%的水加上鈉與氯組成的，但尿液裡含有一個海水中沒有的元素：尿素。尿素是水溶性的有機化合物、能夠幫助身體排出氮。而當尿液與海水結合時，尿素裡的氮會產生出氨鹽基、成為海洋植物的食物…所以，盡情地尿吧！

 

9. 為什麼緊張時會流手汗？

Sweaty palms can be caused by two things: emotional stress and your body trying to regulate its temperature. When you get nervous, scared, or excited your sympathetic nervous system will stimulate Eccrine glands on your face, palms, armpits, and more.
 
手汗的成因有2種：情緒壓力或是你的身體想調節體溫。當你一緊張、害怕或興奮時，你的交感神經系統會在你的臉上、手掌、腋下或其他地方，激發出分泌物、也就是汗。

 

10. 為什麼我們喜歡在洗澡時唱歌？

The reasons why you uncontrollably sing are more based on theory. People feel relaxed and comfortable in the shower and they're also alone (well, sometimes). When your body is physically comfortable, you become for mentally comfortable making you more apt to sing. Another theory is that everything surrounding you creates a great acoustic environment that makes your voice seem fuller.
 
你洗澡時會忍不住想唱歌其實是有原因的。人們在洗澡時感到放鬆跟舒適，而且通常是自己一個人獨處，而當身體感到舒適時、心理也同樣會感到舒適，所以這樣的好心情會讓你想唱歌。除此之外也有其他說法，像是因為浴室裡的環境可以創造出超棒的音效 (回音之類)，讓你的聲音聽起來更飽滿、更好聽！

 

11. 為什麼咖啡讓人想便便？

Everyone knows that feeling when you're about half-way through your morning coffee and then immediately looking for the bathroom. This happens because coffee helps stimulate muscle contractions in your large intestine and next thing you know, BOOM!
 
每個人應該都有這種經驗，就是在早上時喝咖啡喝到一半，就開始想找廁所了。原因就是咖啡會刺激你大腸的肌肉收縮，這時你就會開始想跑廁所了。

 

12. 為什麼我們有乳頭？(探討的是男性的乳頭)

In the beginning weeks of being in the womb, the embryo starts as a woman and follows that blueprint until testosterone plays its part in males and changes the genetic activity of cells in the genitals and brain. The nipples are there for good after that.
 
在懷孕的前幾週時，子宮裡胚胎的性別其實是從女性開始發展的，一直到睪丸激素開始在胚胎裡作用、將生殖器與大腦裡的基因細胞改變，胚胎才會變成男生。所以一開始便發展出的乳頭就在這改變後就一直繼續存在了。
