Why do Americans think that it is important to change bed sheets once a week?

What are the most important things in the house? Surely in the top-3 includes a bed. In bed, we spend a significant part of our lives: this is a place for sleeping, for love comforts, and for reading at night, sometimes even for breakfast.
However, this piece of furniture is liked not only by us - it is also a favorite place of harmful bacteria and fungi, and from a cozy “fortress” the bed can easily turn into a blooming garden of infection. So says New York University’s microbiologist Philip Tierno, writes Rambler.
According to him, bedding should be changed once a week. Otherwise, the microscopic life begins to develop in the folds of sheets, pillowcases and duvet covers, which can even lead to diseases. According to the study of fungal contamination of bed linen, both down and synthetic pillows contain up to 16 types of fungi. Moreover, not all of them are the product of secretions of our body - although sweat, skin particles and other excretions, of course, become an excellent base for their development.
The fungus propagates especially actively in a warm and humid environment, and it is these conditions that we create in bed: only in it a person allocates about 118 liters of sweat per year.
The bed also gets dust and dirt, which we bring from the street. And those who have pets, are forced to sleep among the particles of wool and saliva of pets.
Dust gets into bed not only directly from the human body: banal gravity plays a huge role here, and even blankets do not completely save the laundry. First, the dust has the ability to penetrate the smallest crevices between the bed and the bedspread, and secondly, spreading and making the bed, in one motion we raise a whole cloud of dust deposited on the bedclothes.
Of course, we can not consider all this stuff with the naked eye. However, if we could, we would no longer want to sleep among such mud. And the matter here is not even so much in the aesthetic component, but rather in the fact that during sleep our mouth and nose are extremely close to the bedding, and therefore we actually breathe all that is on it.
For asthmatics and allergies, it can be doubly dangerous.
But even in a healthy person, constant inhalation of dust and dirt that has accumulated after one or two weeks of using the laundry can cause sore throat and other unpleasant symptoms, and I don’t want to think about what the fungus can do.
