Most of the cold is caused by a virus and spreads through the respiratory tract and contact. Objects such as towels will often touch people's faces, and the residual cold virus will camp on the towel. Healthy people who use a towel with a virus residue may also be at risk of catching a cold. Strictly speaking, after the cold has recovered, the clothes, quilts, towels, etc. that are in contact need to be disinfected, especially towels. Because the towel touches people's faces and hands every day, even when they wash their faces, they will even touch the parts of the human mucous membrane such as eyes, nose and mouth, which will make the cold virus stubborn. The general cold virus only needs to be boiled in water for 5 minutes to disinfect. People's clothes, quilts, etc. can be disinfected by washing and sun exposure. Cotton towels are more suitable for steam sterilizers, and their disinfection principle is the same as boiling water.
After the cold has recovered, it needs to be cooked and thoroughly disinfected.
Most people know that they should be prevented before a cold, and they should seek medical treatment when they have a cold, but they tend to be less nervous after a cold. In fact, in order to avoid repeated colds, some life details can not be ignored after the cold has healed. For example, the used towels are cooked and thoroughly disinfected.
