房间里这么多人 为什么蚊子总叮我?答案竟然是……

2017-05-28 08:05:01   都市快报

当几个人同住一个有蚊子的房间时,经常是有的人被蚊子反复叮咬,而有的人却很少被蚊子叮咬或感觉不到蚊子的存在。

“蚊子爱叮什么人?”随便问问身边的人,答案真是五花八门。

认为蚊子爱叮女性的“性别说”;认为蚊子爱叮O型血的“血型说”;认为爱叮皮肤光滑白嫩的“皮肤好坏说”;还有认为爱叮血液甜者的“血液甜苦说”。

那么,到底哪些人会特别吸引蚊子呢?

二氧化碳排得多的人

人在从事运动或体力劳动后呼吸会加快,这样呼出的二氧化碳相对较多,蚊子对此比较敏感。因此,在人群中,肺活量大的人、胖人、呼吸沉重的人更容易被蚊子叮咬。

汗腺发达的人

喜欢流汗的人,对蚊子产生吸引力。蚊子的触角里有一个受热体,它对温度十分敏感,只要有一点温差变化,便能立即察觉得到。

流汗的人肌体散热快,也会对蚊子产生吸引力,人体排出的汗液在空气中挥发,也能向蚊子发出“信号”。因此汗量多、易出汗的人受蚊子攻击的机会更大。

穿深色衣服的人

蚊子怕光但又不喜欢光线太暗,喜欢在弱光环境下吸血。白天,当人们穿着深色衣服时,反射的光线较暗,恰恰投其所好。另外,蚊子喜欢叮咬体温较高的人,而深色衣服的吸热能力强。几种因素相加,自然使得深色衣服的诱蚊指数大涨。

人体发出信号吸引蚊子

研究表明:蚊子爱叮什么人,与血型、性别等并无直接联系,而主要看人体向蚊子发“信号”能力的强弱与否,强烈的“信号”通过空气传播,能够引导它便捷地找到食物。

温度、光线、声音和气味是影响蚊子吸血的四大因素。

一般来说,蚊子从16℃~17℃开始叮咬,23℃~39℃为最适宜的温度。

蚊子跟踪它的目标时,总是随着人呼出的气味曲折前进直至接触到目标为止,然后就落到皮肤上耐心寻找“突破口”,最后才把“针管”直接插入皮肤里吸血8~10秒钟。

别小看身长不过一厘米的蚊子,它的搜索能力很强,在搜索范围内,“信号”越强的目标,自然也越容易被它们锁定。

夏季驱蚊大法

1、运动后应该尽快洗澡,以保持皮肤清爽。

2、如果日常活动场所内的蚊子较多,应身着长袖衣服。衣服的功能主要是用来遮掩汗液等皮肤分泌物的气味,让蚊子无法追踪而来。

3、户外运动最好穿着白色或浅色衣服。

4、夏天不要因为嫌热而不穿袜子,这样会使汗水气味快速挥发,把蚊子招引过来。

5、驱蚊水不宜和防晒霜共用,因为驱蚊水的成分主要是驱蚊胺和酒精,混用会降低甚至完全抵消驱蚊效果。
