Episode notes
Fever vs. Body Temperature
- Humans maintain a core body temperature around 98.6°F (37°C).
- A fever is not just a high temperature, but a shift in the body's set point.
Causes of Fever
- Fevers are triggered by exogenous substances (e.g., bacterial toxins) and endogenous pyrogens.
- These pyrogens act on the hypothalamus, increasing body temperature.
Adaptive Fever Hypothesis
- Fever may be adaptive, hindering pathogen survival.
- Ectotherms like lizards and fish seek higher temperatures when infected.
