In this Doctors' Notes episode of What’s Up Docs?, Chris and Xand van Tulleken take a deeper dive into hay fever with Professor Stephen Till.

The docs and their guest explore whether hay fever is really becoming more common, and if so, why. From climate change and air pollution to changes in our environment and biodiversity, they unpack the factors that may be making symptoms worse. They also look at how hay fever varies around the world, including why treatments like allergy injections are more widely used in some countries than others. Along the way, they tackle common myths and share practical advice for managing hay fever more effectively.
