Bed sheets can become a gathering place for scary bacteria!

We spend more than a third of our lives in bed - but that place can quickly become a "park" of bacteria and fungi, harmful to health, if the bed sheet is not laundered.

This is a warning by biologist at New York University, Philip Tierno.

Mr. Tierno shared with Business Insider: "If left too long, micro-life in the wrinkles and folds of bed sheets can even make us sick."

To prevent this invisible "wave", Mr Tierno advises us to clean the bed once a week.

People naturally create about 98 liters of sweat in the bed every year. When the weather is hot and humid outside, this amount of sweat becomes the "ideal mushroom culture medium".

We should clean the bed once a week.

In a recent study assessing levels of fungal contamination in beds, researchers found that feather pillows and pillows made from synthetic fibers used for 1.5 to 20 years can contain 4 to 17 species. different mushrooms.

And yet, it's not just the life of the microorganism you're sleeping with. In addition to the fungi and bacteria that come from sweat, sputum, skin cells, and secretions from the vagina and anus, you also share beds with bacteria from external factors.

They also include dead skin cells, pollen, dirt, lint, air dust, and agents from any material that makes bed sheets.

Tierno said that all those things became "significant" in just one week. And unclean sheets are the agents that make you sneeze and sneeze, because bacteria are so close to your mouth and nose that you're almost forced to inhale them.

Tierno added: "Even if you don't have a history of allergies, you can still have an allergic reaction."

Another reason your bedspread gets dirty quickly, has little to do with your behavior or patterns of sweat - the problem is simply gravity .

Tierno stressed: "Gravity can bring all the dust and bacteria into your bedsheets."

Just one to two weeks for this buildup of bacteria is enough to make anyone who has an itchy throat - especially those with allergies or asthma unable to look down. (1/6 of Americans are allergic.)

"If you touch the dog in the street, you want to wash your hands. It's the same as touching the bed sheet if you don't get proper hygiene."
