As the winter chill sets in, throngs of Europeans are heading each week to the nearest pond, lake or coastline to dunk themselves voluntarily in freezing cold water. Cold swimming has centuries of history on this continent, but why do it? This week we're delving into the science of why it makes us feel good — but also why it helps so many people through difficult times, with the help of Katharina Smets, audio maker and proud member of Antwerp's biggest cold plunge club. We're also talking about the Vatican's Christmas tree drama and a festive inflation-busting policy in Greece.

In the winter of 2020, deep into the misery of the global pandemic, Richy Craven lit up the internet with a tale about working at Christmas in a fancy department store in Dublin. His story went viral and we loved it so much that we asked our friend, the writer and podcaster Darach Ó Séaghdha, to read it for us. Producer Katz Laszlo added some audio magic, and a classic episode of The Europeans was born. As a little early Christmas present, here it is again.
