为什么要经常修剪指甲?:

    介绍: 指甲总是剪了又长,剪了又长,而且长出来不想头发一样软软的,指甲是硬硬的,而且我们需要经常剪指甲,小朋友们知道为什么吗?指甲每天都在生长,长时间不剪,越长越长。人的双手每天都会碰到许多东西,因此,受伤会沾满许多细菌和寄生虫卵。这些细菌就在指甲缝里。当我们用手来吃东西的时候,这些细菌就会和食物一起被吃进肚子里了,人就会生病。指甲有两个用处,一是保护手指;二是有利于干活,因为人的手指能够灵活的写字、拿东西,都要靠指甲的支撑。但是如果指甲太长,细菌和污垢便容易藏在指甲缝中。指甲缝中的污垢较难清洁,也不美观。而且,如果指甲太长也容易在无意识的时候,刮伤自己的脸或者碰到硬物导致指甲断裂。指甲这么脏而且长指甲又这么的危险,所以小朋友们要经常修剪指甲,保持清洁卫生。
