British scientists have studied for 25 years the question of how cold feet can cause the development of infectious diseases (colds). It turned out that in every human body there are a large number of bacteria that multiply when the body temperature rises, often as a result of hypothermia. With a cold, the mucous membrane of the nasopharynx is affected - beneficial soil for the ingestion of various harmful bacteria.
Doctors recommend always keep your feet warm and dress for the weather. Those who are prone to frequent colds, it is recommended during walks to protect the nose, which reduces the risk of infection in severe frosts.
