Mosquito Bites! Will Nothing Stop This Itching?
蚊虫叮咬!没有东西能止痒?


There are many myths surrounding the problem of mosquito bites, especially when it comes to curing their itch. Some widely-circulated ones include rubbing bites with a banana peel or soap, applying toothpaste, covering it with sticky tape, or ground-up aspirin. In order to figure out what might work, first we need to figure out why they itch.
有很多关于蚊子叮人的说法,特别是关于止痒的说法。一些广为流传的说法有用香蕉皮或者肥皂擦被咬的地方、涂牙膏、用粘粘的(去掉)胶带或者阿司匹林粉末盖住。要想知道怎么做可能(什么方法有效,我们首先需要搞清楚为什么会发痒。


Female mosquitoes require blood meals when producing eggs (Males feed on nectar instead of blood, so they don’t bite). But they don’t actually bite, they have a needle-like proboscis that jabs into your skin to draw blood out like a syringe. To keep the blood flowing while they suck, the mosquito injects a bit of its saliva that contains an anti-clotting chemical.
母蚊子产卵的时候需要吸食血液。(公蚊子吃的是蜂蜜(花蜜)不是血,所以它们不咬人。)不过它们并没有真的“咬”,它们有一个针一样的喙,能够像注射器一样扎进你的皮肤抽血。为了保持吸食时血流的畅通,蚊子会向人体注射一点点唾液,里面含有抗凝血的化学成分。


As a result, the itching isn’t even caused by the proboscis, but by your own body’s immune response to the mosquito saliva. Your immune system releases histamines to destroy the foreign substance, which causes swelling and itching. Fortunately, the itch only lasts a few hours, so your best bet is just to wait it out. But if you really can’t stand it, doctors recommend ice to reduce swelling and topical anti-itch creams for the itch. If bite symptoms last a very long time or are more severe than normal, consult your doctor right away.

结果(/因此,导致发痒的原因甚至(根本不是喙,而是你自身对蚊子唾液的免疫反应。你的免疫系统释放出的破坏外来物质的组胺引起了肿胀和瘙痒。你的免疫系统释放出组胺来破坏异物,这就是引起肿胀和瘙痒的原因。幸好只会痒几个小时,所以你最好的方法就是等它过去。不过如果你实在不能忍,医生推荐冰敷消肿,再涂一点外用的止痒药膏止痒。如果被咬的症状持续很长时间或者比平常更严重,请立刻去咨询医生。
