Why is the white coat white and the surgical gown is blue?

In fact, this is mainly in order to distinguish the function of the doctor's work, in fact, not only have blue surgical clothing, there is also a part of the surgical clothing is green, many people may think that the white coat into a white, surgical clothing into a blue just to look good, but in fact, this is not the reason, but mainly in order to carry out the intelligent distinction. Before the emergence of modern medicine, in fact, those clothes worn by doctors were not blue or green, not even white. Because at that time the so-called sterilization concept had not yet been formed, so at that time many doctors wore those clothes were dark, because dark clothes even if they were soiled by blood, they would not be particularly conspicuous.

Then someone started to implement the white coat, and the person who implemented the white coat was the founder of the surgical sterilization method, which was actually a British doctor. In fact, the history of the white coat is not particularly long, probably only about 100 years of history. Later, with the development of medical treatment, doing surgery is also become a norm, on the operating table these doctors often see red blood, some times staring at this red blood, may be several hours, after a long time it is easy to brain fatigue phenomenon, so that in doing surgery is very dangerous, this in psychology is people called visual afterimage.

In order to solve this problem, there is a specialized surgical gowns, most of the surgical gowns are blue or green, in order to form a sharp contrast with the red blood. During surgery, doctors can shift their gaze to the blue or green scrubs, which allows them to stay continuously sharp, which is a great benefit for doing surgery.

In fact, careful people can find that many walls inside the operating room are also light blue or green, in fact, the effect is the same as the surgical gowns. So strictly speaking, the color choice of white coats as well as surgical gowns is also to be interpreted from a scientific point of view.
