9 Reasons Why You’re a Mosquito Magnet
Mosquitoes are picky creatures — unsurprising if you’re the one always ducking for cover under a swarm of bloodsuckers while your friend remains unscathed. Good thing scientists are on the hunt to discover what makes certain people especially attractive to the tiny insects. Here are nine reasons they’ve come up with so far.
蚊子很挑剔 – 如果你是那个整天抱怨被很多蚊子叮咬的人，而你的朋友却相安无事，那么你对这种说法肯定不会感到奇怪。科学家正努力探索某类人特别吸引蚊虫的原因。下面是他们迄今为止发现的九个原因。
癫痫病都有啥危险 You Breathe
In many ways, no one is immune. The fact that humans breathe makes us all mosquito targets to varying degrees. More than 30 years ago, researchers discovered that carbon dioxide is one of the main reasons mosquitos seek us out. The insects will fly to higher concentrations of CO2 (i.e. - large groups of people at sporting events and backyard parties), then use other sights and smells to narrow down their target.
大多数情况下无人幸免于蚊虫叮咬。事实上，人类的呼吸使得我们纷纷成为蚊子的目标，但是程度又因人而异。30多年前，研究者发现二氧化碳是蚊子对我们情有独钟的主要原癫痫病要吃什么药好因之一。这种生物会飞到二氧化碳浓度较高的地方(例如 – 在体育赛事和后花园聚会这种人群密集的地方)，然后利用它们的眼睛和鼻子缩小攻击目标。
Because larger people produce more carbon dioxide and more body heat, they’re naturally more attractive to mosquitoes. This is why, when in groups, adults usually get bitten more than children, and men are targeted more often than women.
Along with swollen feet and morning sickness, p癫痫病人能喝黄芪精吗?regnant women are also nearly twice likely to get bitten than those who are not expecting, according to one international study. Two reasons: Pregnant women produce excess amounts of carbon dioxide and body heat.
You Exercise Regularly
During a workout, the body produces a chemical called lactic acid, which is released through sweat glands on the skin. And one German study confirmed that mosquitoes can detect and are attracted t黑龙江癫痫病医院o lactic acid at close range.
Your Feet Stink
One study published in the journal PLOS ONE found that people with a higher abundance but lower diversity of bacteria on their feet are highly attractive to mosquitoes. The bacteria, which is pungent, is also found in Limburger cheese and is so effective at attracting mosquitoes, that scientists are using the cheese to trap and control the flies in Africa.
