為什么要經(jīng)常修剪指甲?:

    介紹: 指甲總是剪了又長,剪了又長,而且長出來不想頭發(fā)一樣軟軟的,指甲是硬硬的,而且我們需要經(jīng)常剪指甲,小朋友們知道為什么嗎?指甲每天都在生長,長時間不剪,越長越長。人的雙手每天都會碰到許多東西,因此,受傷會沾滿許多細菌和寄生蟲卵。這些細菌就在指甲縫里。當我們用手來吃東西的時候,這些細菌就會和食物一起被吃進肚子里了,人就會生病。指甲有兩個用處,一是保護手指;二是有利于干活,因為人的手指能夠靈活的寫字、拿東西,都要靠指甲的支撐。但是如果指甲太長,細菌和污垢便容易藏在指甲縫中。指甲縫中的污垢較難清潔,也不美觀。而且,如果指甲太長也容易在無意識的時候,刮傷自己的臉或者碰到硬物導致指甲斷裂。指甲這么臟而且長指甲又這么的危險,所以小朋友們要經(jīng)常修剪指甲,保持清潔衛(wèi)生。
