They are designed to be easily cleaned, prevent cross-contamination, and facilitate movement for various medical tasks. Additionally, scrubs contribute to a sense of unity and identification within healthcare teams. 

• Scrubs are made from materials that can be easily disinfected and laundered at high temperatures, helping to eliminate bacteria, viruses, and other contaminants. 
• They act as a barrier, minimizing the risk of healthcare workers transferring pathogens to patients and vice versa. 
• The ability to easily change scrubs after each shift or patient interaction further reduces the potential for contamination.
