There’s also stuff on your skin that attracts them. You’ll probably suffer more bites, if you happen to produce more lactic acid, which comes from your sweat glands.
皮肤表面也有吸引蚊子的物质。如果你汗腺分泌发达,皮肤表面产生较多乳酸,你可能会被叮更多包。
Mosquitoes who carry malaria are most attracted to sweat that had been sitting on skin for a day or two, rather than fresh sweat. They’ll also prefer you if you have more of these bacteria living on your skin.
皮肤上残留了一到两天汗液的人,会比刚出汗的人,更容易吸引疟疾媒蚊。如果你的皮肤表面有更多这类细菌,蚊子也就会更偏爱你。
People who produce more carbon dioxide when they exhale are also more likely to get bit. A mosquito can smell this, so it’ll go after them. Larger people and pregnant women suffer most for this.
呼吸时排放较多二氧化碳的人也更容易被叮。蚊子能嗅到从而缠上他们。因此大块头或怀孕的女性往往中招。蚊子触角上的气味接收器是它们引以为傲的法宝——用来探测人呼出的二氧化碳气体、身上的汗液等。因此,驱蚊剂是防止蚊子过于关注你的有效武器。
Another interesting group that happens to get bit more often is beer-drinkers. This might be related to carbon dioxide production as well. People tend to breathe harder after drinking a beer.
另一个有趣的群体也容易被叮,爱喝啤酒的人。这可能也与呼出的二氧化碳有关。喝完酒后人们往往呼吸更加剧烈。
