We spend more than a third of our lives in bed - but that place can quickly blossom into a "botanical park" of bacteria and fungus1, 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 microscopic2 life within the wrinkles and folds of our bed sheets can even make us sick, Tierno told Business Insider.
 
To stem the invisible tide, he said sheets should be washed once a week.
 
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."
 
In a recent study that assessed the level of fungal contamination in bedding, researchers found that feather and synthetic3 pillows between 1.5 and 20 years old can contain between four and 17 different species of fungus.
 
And it's not just your own microbial life you're sleeping with. In addition to the fungi4 and bacteria that come from your sweat, sputum, skin cells, and vaginal and anal excretions, you also share your bed with foreign microbes.
 
These include animal dander, pollen5, soil, lint6, dust mite7 debris8 and faeces, and finishing agents from whatever your sheets are made from, to name a few.
 
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 sniffing9 and sneezing, since the microbes are so close to your mouth and nose that you're almost forced to breathe them in.
 
"Even if you don't have allergies10 per se, you can have an allergic11 response," Tierno said.
