Given the choice between noisy hand dryers and tree-felling paper towels, dryers are the better option, right? Maybe not, at least when it comes to your health.

嘈杂的干手器和砍伐树木的纸巾之间选择,干燥机是更好的选择,对吗?也许不是,至少当它涉及到你的健康。

A University of Leeds study finds hand dryers, especially “jet-air” models, can actually spread germs around a public bathroom.

a university of leeds study 发现干手器,特别是“喷气式”模式,可以传播细菌周围的公共浴室。

To simulate what could linger after poor handwashing, researchers coated participants’ hands with a harmless bacteria not typically found in bathrooms. Participants then dried their hands, and scientists tested bacteria in the air near the various hand-drying options. What they found: The air around jet-air dryers held 27 times more bacteria than was found around paper towels, and 4.5 times more than around warm-air dryers. Further, “a similar pattern was seen for bacterial counts [3 feet] away.”

模拟可能持续贫穷洗手,研究参与者的双手涂无害的细菌通常不会发现在卫生间。然后擦干手,科学家在空气中各种手附近干燥选项供试菌。他们发现:射流周围空气干燥机空气举行27次以上的细菌比被发现周围的纸巾,和4.5倍以上的温暖的空气干燥器。此外,一个类似的模式被视为细菌计数[ 3英尺]了。”

And that bacteria lingers: Half was collected in the air around dryers five minutes after use, with bacteria still hanging around after 15 minutes.

和细菌徘徊:一半是在干燥后用五分钟采集空气,细菌仍然在15分钟后。

"Next time you dry your hands in a public toilet using an electric hand dryer … you may be splattered with bugs from other people’s hands," said lead researcher Mark Wilcox, of the University of Leeds School of Medicine.

“下次你干你的手用电动手烘干机……公共厕所里你可以从其他人的手上的虫子,”首席研究员马克威尔考克斯说,利兹大学医学院的。

He concludes “air dryers may be unsuitable for use in healthcare settings, as they may facilitate microbial cross-contamination.”

他总结说:“空气干燥器也许不适合用在医疗环境中,他们可能有利于微生物的交叉污染。”

But a rep for jet-dryer maker Dyson points out that the “paper towel industry” (specifically, the European Tissue Symposium) funded the “flawed” research, which “tested glove-covered hands, which have been contaminated with unrealistically high levels of bacteria, and not washed.” (It’s not the first study to come to this conclusion .)

但是,一个代表喷射机戴森指出“纸巾行业(特别是,欧洲组织研讨会)资助的“缺陷”的研究,其中“测试手套覆盖的手,已与不切实际的高水平的细菌污染,不洗了。”(这是不 come to this conclusion 。第一研究)
