First, let’s find out why doctors wear white uniforms.
In general, hospitals will have to regularly sanitize staff uniforms. Obviously, because for those who work in hospitals, uniforms, and clothes must be carefully disinfected.
The problem is that many disinfectants have a bleaching effect, and if you use other colors for healthcare workers’ uniforms, these clothes will fade when the disinfectant is used. Therefore, the white uniform is convenient and does not fade.
Second, the choice of white uniforms will make people looking, here are patients and their family members, feel lighter visually, as well as not easily nervous.
White also symbolizes purity and cleanliness. Hospital staff wear “white shirts” to create confidence in a clean and orderly environment, as well as to create peace of mind for patients
If you pay attention, you may also notice that obstetric and pediatric nurses often wear pink uniforms. Is this because pink is a cute color for kids?
Indeed, pink looks very soft, symbolizing warmth and harmony. But what is more important is that most children are afraid of injections, so they have fear and resistance to white uniforms.
The visual effect brought about when doctors use pink uniforms will be much better, and it can also reduce children’s fear of being admitted to the hospital.

Back to the main topic, why don’t doctors and assistants wear white uniforms during surgery?
In fact, from the very beginning, the medical staff in the operating room wore white uniforms. But, everything changed when a doctor discovered the weakness of this white uniform.
Specifically, when the doctor shifted his gaze from the red areas due to the effect of blood on the patient’s body to look at his partner’s white uniform, this person suddenly couldn’t see things.
This phenomenon is like when going outside in winter and seeing the sunlight reflected from the snow, many people will suddenly faint. It is conceivable that most of the time during surgery, doctors are faced with images of the inside of the human body.
In other words, there was always a blood-red shard in their field of vision.

However, the degree and shade of red in each organ of the human body are different, some deep, some shallow. When the eyes are constantly working in this condition, the human eye’s ability to distinguish “red” will gradually weaken. Ultimately, it can lead to “oversaturation” and doctors won’t be able to tell the slight difference in red between different organs.
And such visual disturbances easily cause unnecessary medical errors.
But why use green or blue uniforms, instead of other colors? Does that solve the problem posed above?
Yes, because green or blue is the contrasting color of red.
The role of green or blue is to help doctors refresh the impression of red in vision so that the brain is not sensitive to red.
It’s very simple to do this, as long as they occasionally look at something blue throughout the process. But, it is more convenient to put these “blues” on clothes, so that they can see naturally, instead of forcing them to search for a certain position to look somewhere in the operating room.
​Thus, using green and blue as uniforms in the operating room not only improves the surgeon’s eyesight but also allows them to see different shades of red.
This can help surgeons focus on discerning different nuances of the human body during surgery while reducing the potential for mistakes during a sometimes hours-long procedure. this.
Not to mention, in the operating room environment, the clothes of doctors and nurses are easy to stain with red blood stains. If they wear white, the blood will cause additional red marks on their clothes. Meanwhile, when wearing green and blue uniforms, these red streaks will turn black or brown, thus also acting as a visual correction.
Doctors are not heroes, they are just ordinary people. But the moment when they put on the white uniform, they will suddenly become a high wall between us and the disease.
Please respect them and wish them good health.
