有很多情况会让我们起鸡皮疙瘩。 毫无征兆的冷风吹过,我们的爱人深情的凝视,我们最喜欢的歌手的演唱会,或者也许是一个惊人的故事。 不同的经历会让我们的头发起鸡皮疙瘩,虽然科学知道它是如何发生的,但仍然无法解释具体原因。

就像在头皮上一样,我们的头发有根部,那里有小肌肉,当绷紧或收缩时,使它直立起来。 这个机制相对简单,但神秘之处在于破译原因。 为什么寒冷和让我们感动的东西对我们有完全相同的影响?

最容易被接受的理论是生存本能。 很久以前,我们的祖先拥有比今天多得多的头发和毛发,它们在寒冷时站起来形成一层隔热层,或者警告我们有危险。 但这并不能解释为什么我们在听到自己喜欢的歌曲时起鸡皮疙瘩,不是吗?

根据犹他大学的研究人员米切尔-科尔弗(Mitchell Colver)的说法,有经验的歌手的声带经过训练,可以发出合拍的尖叫,而我们的大脑感受到这些振动的方式与我们是处于危险之中的人一样。

一旦 "危险情况 "过去,大脑就会释放出多巴胺流,这是一种诱发幸福的化学物质。 简而言之,这种寒意就像一种解脱感,我们意识到自己没有危险,可以放松。 人体真的很神奇,不是吗?
