With the festive season approaching in parts of the world, Ruth Alexander explores what’s actually happening in the body during a hangover, why some people suffer more than others, and whether common remedies make any real difference.

How the body processes alcohol and why that can make you feel so bad is explained by Andrew Scholey, Professor of Human Psychopharmacology at Northumbria University in the UK and member of the Alcohol Hangover Research Group.

Marisa Moll, a registered nutritionist from Paraguay, shares her recommendations on what to consume before you drink alcohol to try to reduce the risk of a hangover.

And Jonathon Shears, Professor of English Literature at Keele University in the UK and author of The Hangover, a Literary and Cultural History, reflects on the cultural history of the hangover.
