Is it really normal to sleep for 8 hours undisturbed each night, or is that just an unrealistic expectation? We talk to Darian Leader, author of Why Can't we Sleep? about how people have slept throughout history and how many of our expectations about sleep are driven by social fads.

Dr Moira Junge (Health Psychologist) and Dr David Cunnington (Sleep Physician) host the monthly podcast, Sleep Talk, talking all things sleep.
