The way we sleep has dramatically changed in recent years. Our alarm clock used to be the only piece of tech we associated with sleep, but we now have apps that track our sleep, evaluate its quality, and how much more or less we may need on a day-to-day basis.

Catherine has just co-authored 'Technosleep: Frontiers, Fictions, Futures', a book that examines the relationship between sleep and technology. She joins Jonathan to discuss.
