Why do doctors wear white clothes?

As early as 100 years ago, doctors always wore black clothes. /kloc-in the 0/7th century, the plague began to spread in Europe. At that time, doctors wore robes and were coated with a layer of wax, which could prevent doctors from contracting plague during treatment. Interestingly, this kind of "doctor's uniform" will not be changed or washed from the day when the doctor wears it until it is worn out, so the "doctor's uniform" at that time is usually white, indicating that the hospital is clean;

Secondly, hospital staff have the habit of cleaning, and there are many viruses and bacteria in the hospital. General hospitals often distribute their work clothes to staff when cleaning and disinfecting them. The disinfectant used will change the color of clothes, even colored clothes will turn white after washing for a period of time. White is soft and not easy to stimulate the nerves of patients (of course, many children will be afraid when they see white clothes for a long time).

There are also some special departments that wear different colors. For example, green generally refers to the color worn in emergency rooms and operating rooms. In other words, the green channel means that intensive care units, intensive care units and other intensive care units are generally pink clothes. These clothes with special colors should be separated from ordinary white coats to facilitate work. It was not until the18th century that Louis Pasteur, a French microbiologist and chemist, discovered bacteria. As we all know, he invented pasteurization. Since then, British scientist joseph lister found that infection is often caused by external factors. According to Louis Pasteur's theory, he proposed that the symptoms of postoperative infection were caused by non-disinfection before operation.

Since then, Liszt has proved his theory with practice, adopting disinfection procedures, washing hands carefully before operation, disinfecting surgical instruments and even spraying carbonic acid in the operating room. Wearing clean surgical gowns is an essential part. In order to distinguish the cleanliness of clothes, he chose it. Because white stains easily, it needs to be cleaned and disinfected frequently. Most disinfectants have bleaching effect. If you use clothes of other colors, it is easy to bleach and fade, and white will only become whiter and whiter.
