Few minor1 injuries are as painful as the dreaded2 paper cut. Just thinking about it probably makes you cringe. However, these cuts are usually small, hardly noticeable, and rarely bleed. So what makes them so painful?

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?

A paper cut is similar to a cut with a razor blade, with one major difference. A razor blade makes a smooth, clean incision3 in the skin, leaving behind few if any foreign particles that might cause the wound to become infected. Although it might hurt initially4, the pain brought on by a small razor cut usually fades after a few minutes.

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。

Like a superficial cut by a razor blade, a paper cut smoothly5 parts the skin, but while a clean razor leaves little behind to irritate the wound, a paper cut deposits material that really stings.

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。

Paper is made of pressed wood mulch, and a variety of chemicals. When paper cuts into the skin, chemical coated fibers6, as well as bacteria and tiny particles remain in the wound and stimulate7 pain receptors in the skin.

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。

Because the cut is usually small and shallow, the skin on either side of the wound closes quickly, trapping the fibers and other particles inside. The result is a good deal of pain, and since the closed wound doesn’t allow for much bleeding, the pain seems entirely8 out of proportion to a cut that you can barely detect.

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!
