Episode notes

Is more sleep always better? We all have different chronotypes and we have different sleep needs. Most sleep will be dictated by your biology, so you get what you need. It's worth talking about there have been studies which have irritated me a lot because they've said that if you sleep longer than nine hours, you're going to have a shortened life expectancy.

Sleep can enhance your creativity, lift your spirits, improve your sense of humor, and amplify your sociability. So why do so many of us struggle to get a good night's rest? Russell Foster, a professor of circadian neuroscience at the University of Oxford, says it's because we've let the frantic drumbeat of modern life drown out the steady tick-tock of our biological clocks. That's the bad news. The good news is that Russell's here to share science-backed tips that will have you catching more z's in no time.

Russell's new book is "Life Time: Your Body Clock and Its Essential Roles in Good Health and Sleep."
