"A healthy human immune system continually adapts to its encounters with hostile pathogens, friendly gut microbes, nutritional components and more, overshadowing the influences of . The most common outcome is this lovely combo: congestion and other allergy symptoms, like itchy, watery eyes and sneezing. They found that elevated body temperature sets in motion a series of mechanisms that regulate our immune system. Since most cancer patients' body temperatures are under 36° C, we need to increase the body temperature in order to improve the patient's immune system. A fever is a body temperature that is higher than normal. The body's immune system helps fight off harmful bacteria and viruses. Fever occurs when the hypothalamus gives the order to increase body temperature. During infection, the immune system will cause the body to develop a fever and an increase in blood flow to bring oxygen and other immune cells to where the infection is. The main cells of the immune system are lymphocytes known as B cells and T cells. 23 for example, temperatures in the febrile range (40-41°c) cause a greater than 200-fold reduction in the replication rate of poliovirus in mammalian cells and increase the susceptibility of gram-negative bacteria to serum-induced lysis. The circadian rhythm of the body temperature (CRBT) is a marker of the central biological clock that results from multiple complex biological processes.
