 | | Body temperature normally fluctuates over the day, with the lowest levels at 4 A.M. and the highest at 6 P.M. Therefore, an oral temperature of 37.5°C would strictly be a fever in the morning, but not in the afternoon. |
 | | The endogenous pyrogens (such as interleukin 1) are a part of the innate immune system, produced by phagocytic cells, and cause the increase in the thermoregulatory set-point in the hypothalamus. |
