雾霾的危害有如下几点：
1、影响生态环境。
雾霾天气对公路、铁路、航空、航运、供电系统、农作物生长等均产生重要影响。雾、霾会造成空气质量下降，影响生态环境，给人体健康带来较大危害。

2、影响人体心脑血管疾病
雾霾天对人体心脑血管疾病的影响也很严重，会阻碍正常的血液循环，导致心血管病、高血压、冠心病、脑溢血，可能诱发心绞痛、心肌梗塞、心力衰竭等，使慢性支气管炎出现肺源性心脏病等。

3、不利于儿童成长。
由于雾天日照减少，儿童紫外线照射不足，体内维生素D生成不足，对钙的吸收大大减少，严重的会引起婴儿佝偻病、儿童生长减慢。

4、影响交通安全。
雾霾天气时，由于空气质量差，能见度低，容易引起交通阻塞，发生交通事故。

5、增加患传染病的概率。
雾霾天气还可导致近地层紫外线的减弱，使空气中的传染性病菌的活性增强，传染病增多。
