Surgical gowns are generally not worn underneath. Surgeons often wear scrubs during surgery and cannot wear overalls into the operating room to prevent outside bacteria from being brought into the operating room and increasing the risk of infection. Inside the surgical gown, it is generally not possible to wear clothes, because in the operating room to maintain a certain temperature, the general temperature is relatively high to ensure the patient's body temperature.

If the surgeon wears more clothes, there is a possibility that he or she will sweat a lot during the operation, and there is also a possibility that the surgical gown will get wet and need to be changed midway, in which case it will affect the operation. Moreover, if you wear too much clothing, your forehead will sweat and the sweat drops may drip onto the surgical area, which will increase the risk of infection.
