你知道你應(yīng)該每周洗一次床單嗎

Did you know you should be washing your sheets once a week? Philip Tierno, a microbiologist at New York University, tells Business Insider that your sheets collect an array of bacteria and fungus. The longer you go without washing them, the more bacteria and fungi your sheets accumulate. If left unwashed for too long, your sheets could actually make you sick.

你知道你應(yīng)該每周洗一次床單嗎?紐約大學(xué)微生物學(xué)家菲利普·蒂爾諾(Philip Tierno)告訴《商業(yè)內(nèi)幕》(Business Insider)，你的床單收集了一系列細菌和真菌。你不洗床單的時間越長，你的床單上積累的細菌和真菌就越多。如果長時間不洗，你的床單可能會讓你生病。

A 2018 study published in Environmental and Occupational Disease backs up these claims. Researchers collected bedroom allergens from nearly 7,000 different U.S. households and found three or more detectable allergens in 90 percent of them. For those who don't usually suffer from allergies, these allergens can still cause an allergic reaction.

2018年發(fā)表在《環(huán)境和職業(yè)病》上的一項研究證實了這些說法。研究人員從近7000個不同的美國家庭收集了臥室過敏原，并在其中90%的家庭中發(fā)現(xiàn)了三種或更多可檢測的過敏原。對于那些通常不會過敏的人來說，這些過敏原仍然會引起過敏反應(yīng)。

Your pillows alone can have up to 16 different types of fungus on them, and that's not counting what's on your sheets. Besides the bacteria and fungi, the gunk on your sheets includes sweat, sputum, anal secretions, soil, lint, animal dander, pollen, dust mite debris, and even feces. If you could see what was on your sheets, you'd wash them more often.

單是枕頭上就可能有多達16種不同類型的真菌，這還不包括床單上的真菌。除了細菌和真菌，你床單上的黏液還包括汗液、痰、肛門分泌物、土壤、皮棉、動物皮屑、花粉、塵螨碎屑，甚至糞便。如果你能看到床單上有什么，你就會更經(jīng)常洗它們。
