1. More than one person. If a family shares a towel, since no one has a different health status and living habits, cross-infection is extremely prone to occur.

2. One towel is multi-purpose. In some families, although everyone has a special towel, it is used for washing face, washing hair, bathing, washing feet, wiping sweat, and wiping hands.

3. Do not break or change, reuse. Towels after the expiration date will harden and become dirty, becoming a new source of pollution.

4. Do not pay attention to the hygiene of towels. Many consumers do not wash, cook, and dry towels frequently. And hang wet towels in unventilated bathrooms for a long time, but they don't know that bacteria and viruses live in wet towels for a long time, and they multiply rapidly in geometric numbers.

5. Ignore the hazards of fake and shoddy products. Many low-priced towels are produced from waste, old, fake raw materials and poor-quality dyes. The labels of these fake and shoddy towel products are marked as 100% cotton, which is actually mixed with a considerable proportion of chemical fibers. The price of this kind of low-quality ordinary chemical fiber is lower than that of cotton yarn, but it is not breathable, has poor water absorption and moisture removal, and is easy to fluff. Washing your face with it will irritate the skin. It is used to wipe household items and cannot be wiped clean. There will be water on the surface of the object. Stains remain. What's more serious is that some production companies also use some banned dyes, which contain aniline carcinogens.
