英語閱讀：床單要多久洗一次

　　How often you should wash your bed sheets, according to a microbiologist -- and what happens when you don't

　　We spend more than a third of our lives in bed - but that place can quickly blossom into a "botanical park" of bacteria and fungus , according to New York University microbiologist Philip Tierno.

　　我們有超過三分之一的時間都待在床上，但紐約大學的微生物學家菲利普·提艾諾表示，那里可能會迅速變成細菌和真菌的“植物園”。

　　If left for too long, the microscopic life within the wrinkles and folds of our bed sheets can even make us sick, Tierno said.

　　如果床單褶皺里的微生物停留的時間太長，它們甚至會使我們生病，提艾諾說道。

　　To stem the invisible tide, he said sheets should be washed once a week.

　　他表示，為了阻止這種暗藏的趨勢，我們應該一周洗一次床單。

　　Humans produce roughly 26 gallons of sweat in bed every year. When it's hot and humid outside, thismoisture becomes what scientists call an "ideal fungal culture medium."

　　人類每年在床上會流下大約26加侖的汗水。當外面又熱又潮的時候，這些水分會變成科學家口中“理想的真菌培養基”。

　　In a recent study that assessed the level of fungal contamination in bedding, researchers found that pillows between 1.5 and 20 years old can contain between four and 17 different species of fungus.

　　最近的一項研究檢測了床上的真菌污染水平，研究人員發現，用了一年半的枕頭里可能有四種不同的真菌，而用了二十年的枕頭里可能有十七種不同的真菌。

　　And it's not just your own microbial life you're sleeping with. In addition to the fungi and bacteria that come from your sweat and skin cells, you also share your bed with foreign microbes.

　　你睡覺時藏在你周圍的微生物不僅僅來自你自身。除了你的汗液和皮膚細胞帶來的真菌和細菌，你的床上還有外來的微生物。

　　These include animal dander, pollen, soil, lint and dust mite, to name a few.

　　舉幾個例子來說，這包括動物毛屑、花粉、土壤、纖維屑以及塵螨帶來的微生物。

　　Tierno says all that gunk becomes "significant" in as little as a week. And unclean bedding still exposes you to materials that can trigger the sniffing and sneezing, since the microbes are so close to your mouth and nose that you're almost forced to breathe them in.

　　提艾諾表示，所有的這些討厭的微生物在一周的時間里就會變得“不可忽略”。因為這些微生物離你的鼻子和嘴那么近，而不潔凈的床上用品使你接觸到那些會讓你抽鼻子和打噴嚏的物質，你幾乎是被迫把那些微生物吸入了體內。
