Well, why does our body need a fever at all? After all, it's not so much bacteria that triggers its growth as our immune system. Special substances - pyrogens - are involved in this process. Their release is stimulated by the immune system, which thus reacts to the inflammatory process. Which is most often caused by bacteria or viruses. And the pathogen itself can also produce pyrogens☝🏻 Of great importance in temperature regulation is a small endocrine organ in the brain, the hypothalamus. It controls the temperature balance point, which pyrogens shift in the direction of reducing heat output and increasing its formation inside the body. What is the actual purpose of increasing the temperature? Under such conditions the immune system cells work more efficiently and the activity of bacteria and viruses decreases✔️
