Why do we itch?

Author: BBC World Service May 15, 2026 Duration: 26:28

Why do we feel itchy? So many listeners have emailed in with questions about itchiness, and presenter Anand Jagatia on the case.

We explore why we itch, the different types of itch, the different causes, and why scratching can help with the itchy sensation. 

Anand puts your questions to an expert panel: Dr Sonja Ständer, professor of Dermatology and Neurodermatology at the University of Münster and and Gil Yosipovitch, Professor of Dermatology at the Miller School of Medicine at University of Miami. 

Also joining them from the University of Hull in the UK is Dr Henning Holle who studies the psychology of itch. He’s got an itchy game for Anand, Sonja and Gil to play in the studio, but is it really as simple as he’s letting on?

Presenter: Anand Jagatia

Curiosity drives discovery, and CrowdScience from the BBC World Service is built entirely on that principle. Each episode begins not with a scripted lesson, but with a question sent in by a listener from anywhere in the world. These aren't simple queries with easy answers; they are the wonderfully complex, often quirky puzzles about everyday phenomena and cosmic mysteries that make us all stop and wonder. What does silence sound like? Could we ever photosynthesize like plants? How does a crowd's mood physically spread? The team then embarks on a genuine investigative journey, tracking down the specialists at the very edge of our understanding-neuroscientists, ecologists, physicists, and engineers-to piece together credible, compelling answers. Listening to this podcast feels like having a direct line to the labs and field sites where knowledge is being created. The conversations are deep yet accessible, transforming abstract concepts into relatable stories. It’s a collective exploration where listener curiosity sets the agenda, making each episode a unique and democratic look at the machinery of our world and beyond. You become part of a global community pondering life, Earth, and the universe, one thoughtful question at a time.
