Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken explore every aspect of our health and wellbeing.

In this episode they explore sleep deprivation, something both Chris and Xand experience. Many people have become obsessed with getting the perfect night’s sleep. We’re using gadgets, monitoring how many hours we’re getting each night, and taking supplements. But how worried should we actually be?

Chris and Xand talk to Russell Foster, Professor of Circadian Neuroscience at Oxford University, to seek some reassurance. How do we stop our lack of sleep from keeping us up at night?
