Does the wound on the human body heal faster in summer or in winter?

Wounds should heal faster in summer than in winter.

Because the atmospheric temperature in summer is higher than that in winter, the blood in the human body flows faster, which accelerates the metabolism of various organs in the body, leading to the particularly active red blood cells in the blood. Red blood cells have the function of swallowing and killing harmful bacteria. When there is a wound on the body surface, it is equivalent to creating an entrance for bacteria, and out of the instinct of red blood cells, a large number of red blood cells will gather at the wound, which will effectively protect the wound while swallowing and killing harmful bacteria, so the wound will heal quickly.

In winter, the temperature is low, contrary to the above, so the wound heals slowly in winter.
