How often is it better to wash the sheets?
The humid weather in the south, bedding is easy to breed mites, which will directly affect the comfort of sleep and human health. It is very hot in summer, and the human body secretes more sweat, which accelerates the secretion of oil on the skin surface and makes the sheets more dirty. So, if you live in the south, you'd better change the sheets once a week. If one week is difficult, it should not exceed two weeks at most.
Because the climate in the north is relatively dry, it is relatively difficult to breed mite bacteria, and the autumn and winter seasons in the north are long and the temperature is low, so it is not easy to sweat. In addition, people wear thick pajamas when they sleep in autumn and winter in the north. Relatively speaking, there is less direct contact with the sheets, and the sheets are not easy to get dirty. When the temperature rises in summer, the cleaning frequency can be increased appropriately.
How are the bacteria in the sheets produced?
1. Skin cells shed by human body will become food for mites, and mites and their feces will gradually accumulate on sheets. This will only happen if the sheets are cleaned regularly.
2. Dust, cotton wool, fabric fibers, particles, tiny insects, pollen, soil, sand and cosmetics will also patronize the sheets.
3. Some people have the habit of eating in bed, which will pose no small threat to health. That's how the bacteria on the sheets came from.
4. Sleeping at night If the quilt is too thick, people will still sweat about 1 liter, making the quilt moist and more likely to breed bacteria.
5. Animals' hair, dandruff, fungi, molds, spores, secreted body fluids and other bacteria will also accumulate.
