Chris and Xand continue their conversation about comfort with Dr Tiffany Watt Smith, writer and cultural historian interested in the histories of emotion and medicine, former director of the Centre for the History of Emotions at Queen Mary University of London, and fellow of the Royal Historical Society.

Drs Chris and Xand van Tulleken want to know what nostalgia is, how it can affect us, how it interacts with comfort, why certain things bring us comfort, and what comfort foods are. They also examine how nostalgic foods, like cultural foods for those separated from their culture, can bring us comfort in line with its original definition, and hear Dr Watt Smith’s top tips on getting through winter, informed by history.
