In general, the operating room temperature is kept somewhere around 68°F (20°C) or less, which is pretty chilly by most people’s standards. Some facilities such as pediatric hospitals may keep it warmer at around 70°F (21°C) or higher because kids lose core body temperature more easily during surgeries.
🚨 Although it is commonly thought that we keep it cold in the operating room simply to prevent infection, that is actually not entirely the case. Believe it or not, creating too cold of an environment can actually increase the chances of infection because it lowers the patient’s core body temperature, which reduces their ability to fight infection.
✅ The real reason we keep it cold is to keep the operating room staff comfortable and prevent them from sweating on the surgical field. It can get pretty warm in the OR if you are wearing a gown, hat, lead apron, and working while under the hot OR lights. Having your surgeon or scrub tech sweat on the operating field is not good for anybody, especially the patient.
