别在家里和车里抽烟，也别让客人在家里抽

2004 年全球约 60 万人死于吸别人的烟，其中近三成是孩子。吸到二手烟的人，更容易得高血压、心脏病和卒中。在家里吸到的，比在外面吸到的更伤人。

成本

不花钱，也不占时间。难在要开口，让家人和客人别在家里抽。

收益

2004 年全球有 603,000 人死于二手烟，约占全球死亡的 1.0%，其中 28% 是儿童。把 57 项研究合起来算：吸到二手烟的人和没吸到的人比，得高血压的比值比约为 1.28。心脏病的比值比是 1.39，心肌梗死是 1.50，卒中是 1.36。在家里吸到二手烟的风险，高于在家外吸到的

备注

先管家里，因为在家待得久，而且多项研究合起来看，在家吸到的二手烟比在家外危害更大。二手烟造成的健康损失里，61% 落在孩子身上。自己戒烟见本节第 1 条。
