很少有一些小伤能够像被纸划伤那样让人疼痛和害怕.光是想一想可能就让你不寒而栗了.然而,这种划伤通常伤口很小、很难被察觉到并且不怎么会流血.那为什么被纸划伤会这么疼呢?

被纸划伤跟被剃须刀片划伤很像,但是有一点不同.剃须刀片造成的伤口较为平整,几乎不会留下任何会导致伤口感染的异物.虽然刚被剃须刀片划伤的时候很疼,但是过几分钟疼痛感就会慢慢消退.

被纸划伤的伤口和剃须刀片造成的伤口一样,也很平整.但是干净的刀片不会留下任何物质去刺激伤口,而纸划伤口却会留下一些让人感到疼痛的物质.

纸是由压缩木片和多种化学物质构成的.当纸划过皮肤时,化学涂层纤维、细菌和细小颗粒物就会留在伤口里,对皮肤里的痛觉感受器产生刺激.

由于伤口通常很小且很浅,伤口会很快愈合,同时会把纤维和其他粒子留在伤口里面.所以,你才会感到十分疼痛,由于闭合的伤口几乎不会流血,所以说,即使伤口小到你几乎察觉不到,但是伤口造成的疼痛感却是要人命的!
