Welcome to What's Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken explore the ideas shaping our health and wellbeing. In this episode, they examine fevers. They ask how and why our body sometimes turns up the dial on its internal thermostat, and what, if anything, we should do about it.

To help them answer these questions, they are joined by Dr Catherine Houlihan, a consultant in clinical virology and infectious diseases at University College London Hospitals. She is also a consultant in infection at the Rare and Imported Pathogens Laboratory, UK Health Security Agency.
