Medical staff in Europe used to wear big dresses. Since the biologist Pasteur successfully used disinfection to stop the spread of diseases, the famous British doctor Lester applied Pasteur disinfection to medicine and presided over the hospital reform, replacing the original clothes with white coats.

But later, because the design of this white coat gave everyone a "clean" feeling, many industries used white coats one after another. To put it bluntly, it is just following the trend. There is no special meaning.

Chef, snack bar guy, after the founding of New China, many industries have provided professional uniforms and "white coats" for fire doctors. In fact, at that time, medical workers in Europe and America had already changed the color from white to "pink" and "light green". It's not that scary for patients.

And our researchers obviously didn't keep up with the form, and ... they probably don't need any clothes, so it's natural for white coats to be used as work clothes.
