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.
纽约大学的微生物学家菲利普•缇艾诺指出,我们有超过三分之一的人生都是在床上度过的,而我们的床可以迅速发展成细菌和真菌的“植物园”。
If left for too long, the microscopic life within the wrinkles and folds of our bed sheets can even make us sick, Tierno told Business Insider.
缇艾诺告诉商业内幕网说,如果床单太久不洗,床单皱褶里的微生物就会让我们生病。
To stem the invisible tide, he said sheets should be washed once a week.
为了防范于未然,他表示床单应该每周洗一次。
Humans naturally produce roughly 26 gallons of sweat in bed every year. When it's hot and humid outside, this moisture becomes what scientists call an "ideal fungal culture medium."
人类每年在床上自然分泌的汗液达26加仑。如果外面炎热潮湿,床上的湿度就会变成科学家所说的“理想的真菌培养基”。
In a recent study that assessed the level of fungal contamination in bedding, researchers found that feather and synthetic pillows between 1.5 and 20 years old can contain between four and 17 different species of fungus.
最近的一项研究评估了床上用品的真菌污染水平,研究人员发现,使用年限在1.5年和20年之间的羽绒和化纤枕头含有4到17种不同的真菌。
