躲避二手煙傷害，真有效的方法只有這 1 個（不是憋氣）

抽煙的危害，早已人盡皆知[1-2]

致癌物順著呼吸道進(jìn)入身體

傷害遍布全身，更會傷害身邊人，簡直要命！

2019 年，約有 130 萬人死于二手煙[3-4]

世界衛(wèi)生組織數(shù)據(jù)庫的調(diào)查結(jié)果顯示[5]

都暴露在二手煙的污染下！

簡直無孔不入！！！

馬路、工位、電梯、餐廳、高鐵站臺……

只要有一個人抽煙

煙臭味就會噴薄而出、久久不消散

碰到二手煙，很多人的第一選擇可能是：

立馬憋氣、捂住口鼻、不敢再呼吸

覺得只要不把有害氣體吸入身體里

就能幫自己避開致癌物傷害

但真相是：

當(dāng)你聞到煙味的那一刻，致癌有害物質(zhì)

就已經(jīng)和鼻腔、口腔、呼吸道黏膜接觸了

根本躲不掉

憋氣暫時減少吸入量，卻無法阻止有害物吸收

即使只是短暫接觸二手煙（幾分鐘～幾小時）

哪怕只是吸入了一點點，都會帶來傷害[6]

例如本不吸煙的女性，二手煙會帶來

更高的呼吸系統(tǒng)疾病（尤其是肺癌）風(fēng)險

絕經(jīng)前患乳腺癌的風(fēng)險[7]

憋氣、捂嘴、戴口罩……都擋不住二手煙！

不同類型的口罩濾過率、吸附性差異大

即使能過濾掉煙霧中的 PM 2.5

也過濾不掉煙霧中所有的有毒物質(zhì)[8]

口罩也難以完全密封貼合面部

害人的二手煙總有辦法趁虛而入

更可怕的是

二手煙還會變成三手煙

其中的有毒物質(zhì)

吸附在衣服、頭發(fā)、地板、家具等各種物品上

幾周到幾個月都不會消散

甚至進(jìn)一步轉(zhuǎn)化成強(qiáng)效致癌的煙草特有亞硝胺[9]

在不經(jīng)意間經(jīng)吸入、攝入、皮膚接觸進(jìn)入身體

連從不接觸煙草的嬰幼兒，都難逃毒手[10]

嬰幼兒呼吸頻率更快、皮膚更薄、更喜歡把手放在嘴里

更容易被迫攝入有害、致癌物質(zhì)

研究發(fā)現(xiàn)：

在不接觸煙草制品的兒童中

95.2% 的手上都檢測到了尼古丁物質(zhì)殘留[11]

在嚴(yán)格禁煙的新生兒重癥監(jiān)護(hù)室

有吸煙者探視后

嬰兒尿液中出現(xiàn)了煙草致癌物的代謝產(chǎn)物[12]

這些有害物質(zhì)

會直接或間接攻擊嬰幼兒的生長發(fā)育

影響孩子的體格、認(rèn)知、行為、呼吸系統(tǒng)功能

帶來潛在致癌風(fēng)險……[13-16]

總而言之：

二手煙暴露沒有安全水平，

哪怕一點點都會危害健康

屏住呼吸、戴上口罩，都擋不住傷害

想要避免，唯一有效的辦法就是

??公共環(huán)境中 100% 無煙??

下次碰到二手煙，快跑！

跑得越快、越遠(yuǎn)越好！

在公共場所吸煙、散播二手煙，本就不道德

為什么是受害者要「趕緊跑」？？？

公共場所拒絕二手煙

是我們的權(quán)利！

更有法律為我們撐腰！

碰到在公共場所吸煙的人

我們可以勸阻！可以舉報！

勇敢捍衛(wèi)自己的健康！

公共場所吸煙，是不文明行為

更是影響公共健康的行為

對不文明吸煙行為說不

是維護(hù)公共環(huán)境和個人健康的合理訴求

新的一年，共同發(fā)聲

創(chuàng)造無煙公共環(huán)境

和丁香一起：讓健康更多，讓生活更好！
