Fever is a state of increased body temperature, resulting from a change in the settings in the thermoregulatory center. It is a systemic symptom of various diseases and disorders.
It is primarily a defensive reaction in response to various types of infections, inflammations, and other abnormalities in functioning. In the case of infections, it can therefore play a positive role. Due to fever, the production of immune cells called lymphocytes increases, and antibodies are directed against germs. Moreover, high temperature makes it difficult for pathogens to multiply.
On the other hand, remember that fever can also occur on a non-infectious basis, including, among others, in the course of autoimmune diseases, with lymphoma or heart attacks.
