Episode Details

A fever is not an uncontrolled overheat, but a deliberate adjustment of the brain's internal thermostat. This episode examines the biological purpose of elevated body temperatures, exploring how heat sharpens immune defenses while levying a steep metabolic cost. From pediatric intensive care studies to clinical trials in Malawi, the discussion untangles why standard guidelines advise reducing fevers even when research shows that treating them rarely improves or worsens illness outcomes.
