What do you need to know about your nose?

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 turn their attention to the nose, an organ we use with every breath but rarely stop to think about.

Joined by Miss Katherine Whitcroft, ear, nose, and throat surgeon at Sheffield Children's Hospital and co-director of the Sheffield Chemosensory Research Lab, Chris and Xand explore how the nose is built and what it does for us, why we produce so much mucus and where it goes, and why our noses run when we cry or eat spicy food. The conversation also covers how our sense of smell changes across our lives, the most common things that go wrong with the nose, and what the evidence says about treatments such as nasal sprays.
