Traditional thinking holds that summer is more susceptible to infection and winter is not easy to recover. These ideas have been proved to be unfounded by clinical practice. Because the operation is carried out in a sterile environment and aseptic operation, antibiotics will be prevented after operation, so the probability of infection in winter and summer is very low. On the contrary, blood circulation and metabolism are accelerated in summer, which makes it less susceptible to infection. In winter, the human body's ability to store energy and absorb nutrients is stronger, and it will be stronger after adjustment in winter after surgery. Based on various factors, we can see that, as higher animals living in modern times, seasonal changes and natural changes have little influence on human body, each season has its own characteristics, and each season is the golden season for surgery.
