三手烟的危害同样不可忽视

Third-hand smoke exposure can cripple your brain and liver, affecting your mannerisms, increasing your risk of neurodegenerative diseases, and ruining your metabolism. That is according to a study by researchers at the University of California, Riverside who saw significant health issues in people within a month of exposure to smoke.

美国加利福尼亚大学里弗赛德分校的一项研究显示，三手烟可能损伤人类的大脑和肝脏，影响行为举止，增加患神经系统退行性疾病的风险，破坏新陈代谢。研究人员发现，人在三手烟中暴露一个月会出现明显的健康问题。

The research team analyzed how people were affected by inhaling smoke from another person's clothing, hair, home, or car.

In previous studies on mice, the same scientists showed third-hand smoke can cause type 2 diabetes, hyperactivity, liver and lung damage, and wound-healing complications. Now, they have shown they can even see an impact on brain and liver tissues.

Damage to the liver can hinder its capability to detoxify the body, leading to more damage by THS toxins.

THS toxins, which are invisible but can be smelled, remain on surfaces for many years, and are resistant to even strong cleaning agents.

Further, they accumulate and age by reacting with the ambient air, and change into carcinogenic chemicals.

Because THS is absorbed through skin, children are especially vulnerable given their close contact with household surfaces.

Children frequently ingest these toxins by putting their hands in their mouths. They also absorb them through the skin.
