In this special programme for Radio 3’s Twilight Season, Michael Berkeley’s guest is the sleep scientist Professor Matthew Walker.

So many of us have trouble sleeping, and are longing to find the secret of a good night’s rest, that when Matthew Walker goes to parties he is more likely to tell people he is a dolphin trainer than the world’s leading expert on sleep science. Otherwise, he says, ‘for me the evening is over’.

Matthew began his career in Britain, training as a doctor, but he is now Professor of Neuroscience and Psychology at the University of Berkeley, California and the founder and director of the Centre for Sleep Science. He is the author of more than 100 scientific papers and his best-selling book Why We Sleep has been translated into over 40 languages.

Matthew tells Michael about the ‘global sleep crisis’, the sleep deficit that is costing individuals their health and economies billions. He explains why it is so important to get at least seven hours of sleep a night and the dangers to our physical and mental health if we regularly get even an hour less than that. And he describes the joys of sleeping and dreaming, and the magic they work on our creativity, memory and wellbeing.

Matthew has chosen music with a restful, sleep-inducing tempo and rhythm by Debussy, Chopin, Handel and Purcell, as well as a track that transports him back to his home town of Liverpool.

And he tells Michael about the most important scientific conversation of his career – with a pianist.
