Scrubs are a type of protective clothing worn in medical environments. They are typically made of lightweight material, such as cotton or polyester-cotton blend, and cover the entire body except for the face, hands, and feet. Scrubs usually come in green, blue or white colors, which help distinguish them from other medical personnel. Using scrubs helps prevent infections since they can be easily changed, washed and disinfected. Additionally, they create a sterile environment by providing ease of movement and reducing interference with equipment or tools used during procedures.
