How often do you need to change bedding?
According to Philip Tierno, a New York microbiologist, in an interview with Business Insider, we spend more than a third of our lives in bed, so this place can easily turn into a “botanical garden” of bacteria. “If you don’t change the laundry for too long, microscopic life in the folds of our bedding can cause serious discomfort and even pain,” says Tierno.

To avoid this, the expert advises to wash the sheets and duvet covers once a week. Why is it important? People, according to IFL Science, produce about 100 liters of sweat per year. When it's hot and humid outside (hello, summer!), This double humidity becomes an ideal environment for fungal culture. In a recent study, which assessed the level of contamination of bedding with mushrooms, scientists found that on average, 16 types of fungi were contained in down and synthetic pillow samples (shelf life from 1 year to 20 years).
But this, alas, is not all. In addition to the fungi and bacteria that come from your sweat, sputum, skin cells, vaginal and anal secretions, you also share your bed with “visiting” microbes. These include, for example, animal hair and dander, pollen, soil, and so on.
Philip Tierno notes that “all this trash” becomes significant in a week - that’s why after this period you need to take action. In addition, keep in mind that if you suddenly had an allergy that you never had, then all the same bedding may be to blame. Just because microbes that can provoke an attack are very close to the mucous membranes.
