But have you ever wondered why 這種起雞皮疙瘩的經驗。但你有沒有想過 this strange change takes over your body? Named after the way poultry looks 為什麼你的身體會有這種反應?名稱的由來很明顯的是因為 when plucked, goosebumps are a fairly useless trait in humans which have been passed 看起來像拔光毛的雞,雞皮疙瘩是一個從祖先那得到的一個比較無用的特徵。 on by our ancestors. Each hair actually has a tiny muscle attached to it called 每根毛髮實際上都連接著一個稱作豎毛肌的 the erector-pili muscles and when these muscles contract the hair stands up on 微小肌肉,當他收縮的時候毛髮就會豎立起來 end. This contraction creates a shallow depression around the hair causing the 並且使毛髮周圍連接的皮膚處向下凹陷,造成 surrounding area to protrude. And it's the stress hormone adrenaline which 中間突起。而這種生理反應是 triggers this physiological change to occur. So what triggers adrenaline? For 由腎上腺素催動的。那又是什麼原因讓我們分泌腎上腺素? one being cold, in animals with much more hair on their body this response helps 當很冷的時候,對於多毛的動物來說豎立毛髮有助於 them to stay warm. The standing hair is able to trap more air and thermal 他們保持溫暖。站立的毛髮間隙裡有較多空氣 regulate it ultimately providing an insulated barrier. Apart from this 來調節溫度,以防止體溫喪失。除此之外 adrenaline is also triggered under stressful situations leading to the 腎上腺素濃度也會因為壓力上升而增加,幫助你 "fight or flight" response, like when you're scared. Cats are a perfect example, 選擇要逃跑或是戰鬥,譬如當你被嚇到的時候。貓就是一個很好的例子 if you give them a spook their hair shoots up on end. 如果你嚇貓,牠們的毛就會站起來。 This involuntary evolutionary response allows animals to appear bigger and 這種反射動作,讓動物看起來比較大 more intimidating. But why music has the ability to cause chills or "frisson" as 也更嚇人。但是,為什麼音樂也會引起雞皮疙瘩 it's called is not fully understood. One interesting theory suggests that 他的原因還沒有被完全證實。其中一個有趣的理論是 elements of music such as sudden volume changes or unexpected unique sections 當音樂的音量突然增加或是某個意想不到的音樂元素 induce a sub-conscious fear response. The body loves predictability and so 會引起潛意識的恐懼反應。你的身體偏好可預測性 anything surprising to the autonomic system stimulates an alarm. But this fear 而意料外的事物會讓自主神經產生警報。但大腦很快 quickly subsides as our brain realizes, "hey, it's just music". And this contrast in 很快就了解到"嘿,這只是音樂"。這種情緒上的對比 experience causes the frisson and your goosebumps. There are other 導致你產生雞皮疙瘩的反應。還有其他的 theories as well, ultimately the brain is extremely complex and so a relationship 不同的理論,我們的大腦非常的複雜, between music, emotion and physiological responses is difficult to decipher but 音樂、情緒與生理反應之間的交互作用更是難以解釋,而 in science it's okay to say that we don't know...yet. 在科學上來講,可以說我們還不清楚他的原因。 Got a burning question you want answered?
