6 坨关于鼻屎的误解和冷知识

误解一:鼻屎好恶心,是鼻子里的脏东西。对那些想入侵你身体的细菌和脏东西来说,你脸上有两个好方便的洞。鼻涕(鼻腔粘液)会捕捉你吸入的各种脏东西,包裹它们变干变硬(像牡蛎造珍珠一样)变成鼻屎把这些脏东西带走,阻止它们入侵。因此鼻屎算是这套防御系统的副产品。误解二:鼻涕里全是细菌,只有生病的时候才有鼻涕。鼻涕95%都是水,成年人每天差不多要分泌600至700毫升的鼻涕,比一瓶农夫山泉都多。你生病的时候会

误解一:鼻屎好恶心,是鼻子里的脏东西。



对那些想入侵你身体的细菌和脏东西来说,你脸上有两个好方便的洞。鼻涕(鼻腔粘液)会捕捉你吸入的各种脏东西,包裹它们变干变硬(像牡蛎造珍珠一样)变成鼻屎把这些脏东西带走,阻止它们入侵。因此鼻屎算是这套防御系统的副产品。

误解二:鼻涕里全是细菌,只有生病的时候才有鼻涕。



鼻涕95%都是水,成年人每天差不多要分泌600至700毫升的鼻涕,比一瓶农夫山泉都多。你生病的时候会分泌更粘更多的鼻涕。黄鼻涕里裹着战死的白细胞尸体,绿鼻涕表示你鼻子里的生态环境正在恢复稳定。

误解三:鼻涕不能到处抹。



鼻涕里含有的3%的粘蛋白,这种物质有很神奇的抗菌功效,可以作为某些医疗器械表面的清洁涂层。嗯,即使这样,还是不太推荐你用鼻涕到处去抹。

误解四:鼻子堵了要使劲擤鼻涕。




鼻子堵了不是因为鼻涕太多,而是鼻腔血管肿胀导致你脸上的下水系统瘫痪了。这时如果使劲擤鼻涕,会起到反效果。擤鼻涕对鼻腔造成的压力(约66毫米汞柱)远大于咳嗽和打喷嚏,甚至会把鼻涕压入鼻窦,造成更深层的感染。用力擤5次鼻涕相当于你往鼻窦里压进了一茶勺鼻涕。那鼻子堵了怎么办?有两个方法:一,轻轻地,非常温柔地,擤鼻涕,一次一个孔。二,把鼻涕吸回去,咽了,或者吐出来。学会了?

误解五:只有小屁孩才挖鼻孔。




调查显示,100%的成年人都会挖鼻孔,几乎到了痴迷的程度。太沉迷于挖鼻孔是一种病(rhinotillexomania),不过心理学家也无法明确定义“只是取出鼻屎”和“对鼻孔进行疯狂扫荡”之间的界限。

误解六:我吃鼻屎,我是不是变态。




好多人都会吃鼻屎,事实上把鼻屎吃进去可能对你的免疫系统有好处!鼻涕本来就是你免疫系统的产物,再说,你以为你每天分泌的一大瓶子鼻涕都哪去了?当然是从鼻腔后面流到你的胃里去了。

难不成应该把鼻涕咽下去?
