为什么蚊子喜欢咬你

蚊子的唾液中有一种物质具有扩张血管和抗凝血的作用，可以使血液更容易流向被咬的地方。被蚊子叮咬后，被叮咬者的皮肤往往会出现肿胀瘙痒的症状，几乎每个人都有被蚊子叮咬的不愉快经历。我们来看看为什么蚊子总是喜欢咬你！

为什么蚊子喜欢咬你

为什么蚊子喜欢咬你？

1.蚊子喜欢咬体温高、呼出二氧化碳多的人，是因为天线里有一个发热体，对温度非常敏感，可以锁定50米外的“目标”，所以体温高、呼出二氧化碳多的人更容易被蚊子咬到。

2.蚊子喜欢咬有体味的人。有时候蚊子靠近不一定会咬人，主要看皮肤的气味。每个人皮肤的化学成分是不同的。比如经常出汗的人皮肤表面有乳酸排出，容易吸引蚊子。

3.蚊子喜欢咬过妆或者喷过发胶的人，因为化妆品中的硬脂酸(一种脂肪酸)残留在这些人中的大部分，而且这种硬脂酸对蚊子也很有吸引力。

4.蚊子喜欢咬穿深色衣服的人。因为蚊子有天黑的习惯，黑色是蚊子攻击的第一目标，其次是蓝色、红色和绿色，所以夏天晚上最好穿白色或浅色的棉衣。

5.蚊子喜欢咬孕妇。孕妇被蚊子叮咬的几率是其他女性的两倍。这是因为孕妇呼出的气体中含有多种容易吸引蚊子的化学物质，而且孕妇腹部温度较高，皮肤表面的挥发性物质相对较多。

6.蚊子喜欢咬喝酒的人。在室外喝一两杯啤酒后，被蚊子叮咬的几率会增加15%。饮酒后体味和呼吸的变化会使人更容易吸引蚊子，饮酒会降低身体防御蚊虫叮咬的能力。

被蚊子咬有哪些危害？

1.按蚊传播的疟疾：疟疾是由按蚊传播的，疟疾也叫疟疾。根据1935年卫生部进行的一项调查，在疟疾流行的地区，50%的居民血液中有疟原虫，72%的居民患有恶性疟疾。

2.流行性乙型脑炎：乙脑、乙脑等。患者有发热、头痛、呕吐、抽搐、嗜睡、昏迷等现象。没有特效药治疗，死亡率相当高。

3.丝虫病：丝虫病由中华按蚊、微小按蚊、淡色库蚊、致倦库蚊等4属30余种蚊虫传播。人是唯一的最终宿主，一般容易感染。

4.传染性登革热：伊蚊是传播登革热病毒的主要蚊种。因为伊蚊有黑白相间的斑纹，所以也被称为黑斑蚊。

怎样驱蚊的效果最好？

1.家庭环境防蚊

(1)室内水生观赏植物应至少每周换水一次或改为养在沙中。

检查锅碗瓢盆、地漏、下水道、花盆等。在你家里。如果你有盖子，要经常换水。

(3)地漏、下水道等处要防止积水，并经常喷洒一些农药，不要对蚊虫的生存环境造成影响。

注意关闭纱窗和纱门，不要让门大开着让蚊子开进来。

室内卫生死角应拆除，减少蚊虫滋生地。

出差或不住久了，要把马桶盖、水槽、水池的水放干净，防止蚊子产卵。

蚊子爱躲在暖气片里、床下、桌下、墙角等隐蔽的地方，可以用蚊香熏出来再杀死。

2.植物和植物油驱蚊

凉油风油精华驱蚊：将两三瓶未盖的凉油放在座椅下、床头柜旁，风油精华滴在蚊香上效果更好。

薄荷油：薄荷油不仅能驱蚊，还能有效杀灭蚊虫幼虫。使用薄荷油可以驱除85%的各种蚊子。

艾叶：艾叶能驱散蚊虫。天黑时，点上艾叶，关上门，抽支烟

穿黄色、白色等浅色衣服可以减少被蚊子叮咬的机会。

4.环境驱蚊措施

晚上关掉室内灯，打开门窗，然后关上纱窗的纱门，防止蚊虫飞进。

卧室放几盒未盖盖子的清凉油和风油精，将樟脑丸研末撒在房间角落驱蚊。

在室内花盆里种一两个西红柿，西红柿枝叶散发的气味会驱走蚊子。

室内安装橙色灯泡，或用透明橙色玻璃纸覆盖灯泡，可部分驱蚊。

烧干茶叶和橘子皮可以熏走蚊子。

将适量薄荷、紫苏或番茄叶的汁液涂抹在人体裸露的皮肤上，防止蚊虫叮咬。

在灯下挂一束葱，或者用纱布包一些葱，帮助驱蚊。

5.防止蚊子进入。

仔细检查纱窗，不要有任何孔洞或闪缝。

多注意下水道等潮湿场所的卫生，避免蚊虫滋生。

(3)注意屋外卫生，经常喷杀蚊虫的杀虫剂，如蜜海灵。

为了健康，购买绿色无害的电蚊香使用。

当然，另一种偷懒的方式是睡前使用蚊帐和涂抹防蚊水。
