The Science Behind Green Surgical Scrubs

In the medical world, the sight of healthcare professionals clad in surgical scrubs is a common one, with green being one of the most prevalent colors. Ever wondered why green is so prominent in operating rooms and surgical settings? This choice is not merely a matter of tradition or aesthetic preference; there are scientific reasons behind the selection of green for surgical scrubs, making it an integral part of the surgical environment.

Enhancing Visual Acuity

The primary reason for the use of green scrubs is related to the way our eyes perceive colours and the impact of contrasting colors on visual acuity. During surgery, medical staff spend long periods focusing on red tones, which are abundant in the human body. Staring at red for extended periods can cause a green afterimage to appear when looking away, due to the way photoreceptors in the eyes adjust to color saturation. Green and blue tones provide a high-contrast backdrop to the reds of bodily tissues, reducing eye fatigue and making it easier for surgeons to focus with greater clarity over longer periods.

Reducing Eye Fatigue

Green is considered a restful color that minimises eye fatigue. In the high-stakes environment of an operating room, where precision and concentration are paramount, reducing eye strain is crucial. The use of green scrubs and drapes helps to create a more visually comfortable environment for the surgical team, allowing them to concentrate better on the task at hand without the distraction of eye strain or the discomfort of afterimages.

Improving Perception of Depth and Detail

The contrast provided by green surgical attire can also enhance the perception of depth and detail within the surgical field. By offering a colour that sharply contrasts with human tissues, green scrubs make it easier for surgeons and medical staff to navigate the nuances of human anatomy, leading to potentially safer and more efficient surgical procedures.

Psychological Benefits

Beyond the physiological reasons, green scrubs offer psychological benefits. Green is often associated with calmness, cleanliness, and healing. These associations can positively affect both the medical staff's and patients' mental states, promoting a sense of calm and focus in an environment where stress and tension can run high.

Evolution of Surgical Attire

The adoption of green surgical scrubs marks a significant evolution from the traditional white attire that dominated hospitals and operating rooms in the past. White, while symbolising cleanliness, proved impractical due to its tendency to quickly show stains and become discoloured over time. The shift to green not only addressed the practical issues associated with white uniforms but also brought the aforementioned benefits to the surgical environment.
