why do doctors wear blue blouse?

Blue shirts are usually white - the color of cleanliness. According to an article in 1998's Today's Surgical Nurse, by the beginning of the 20th century, a big influential doctor turned blue to blue because he thought it looked easier. Although it is difficult to confirm whether blue and green shirts become popular for this reason, blue is particularly suitable in helping doctors look better in the operating room because it is the opposite of red.

Blue can help doctors look better for two reasons. First, looking at the dark blue or light blue makes the doctor see the objects more red, including the bloody stools of the patient's body during surgery. The brain recognizes colors that are related to each other. If the surgeon looks at something red or pink, he becomes saturated with it . The red signal on the brain fades, making it more difficult to observe the nuances of the human body. Regularly looking at something blue can make your eyes more sensitive to different shades of red, according to John Werner, a psychologist who specializes in vision at the University of California, Davis.

Second, focusing too heavily on red can lead to blue hallucinations on a white background. Blue ghosts may appear if the doctor shifts the eye from red tissue in the body to something white, such as surgical bamboo blinds or anesthesiologist's clothes. A blue illusion of red inside the patient's body may appear on a white background. (You can try the illusion 'after the impact' yourself).Illusions can follow wherever the surgeon looks , similar to floating points we see after the flash of the camera.

This phenomenon occurs because white light contains all the colors of the rainbow, including red and blue. But when the eyes are tired with red, the competition between red and blue causes the brain to signal 'green'.

According to Paola Bressan, who studies visual illusion at the University of Padova (Italy), however, if the doctor looks at blue blue instead of white, unpleasant ghosts will blend into blue and cause no harm. romantic

So even though the doctor went down the street with all-colored wings, blue was always the best choice for them.
