What happens as your body temperature changes.
Increased body temperature is usually induced by some sort of infection, but can be seen with toxin ingestion, malignancy, drug reactions and autoimmune conditions. What is normal body temperature? We generally define 37 degrees C (98.6 degrees F) as normal body temperature based on observations made by Wunderlich over 120 years ago. In fact, our body temperature is not constant and is generally lower in the morning and higher in the early evening. In women, body temperature is slightly lower during ovulation. Therefore, physicians have arbitrarily set 38.3 degrees C (100.96 degrees F) as the cutoff point of when they start to get concerned about one's body temperature. Fevers are induced by substances called pyrogens which can be endogenous or exogenous. Although most bacteria have toxins that directly activate the body's central thermoregulatory areas in the brain, they also induce the body to produce endogenous pyrogens as a normal part of the immune response. When the body responds to an infection it produces substances called cytokines which activates the immune system to fight off the infection. Some of these cytokines (interleukin-1 alpha and beta, tumor necrosis factor alpha and beta, interferon alpha and interleukin-6) also signal the anterior hypothalamus (the brain's thermostat) to produce more prostaglandin E2 (PGE2). Elevated PGE2 cause the body to increase both heat production and heat conservation mechanisms which results in the elevation of the core body temperature

314 K – 41 C - 106 F Heatstroke/Sunstroke: Prior to unconsciousness the person may experience dizziness, fainting, tingling, and mental confusion. If untreated, heatstroke is often fatal, because prolonged fever can cause brain damage, shock, or heart or kidney failure, especially in persons with underlying disease.
