The Science of Sleep with Matthew Walker

City Arts & Lectures

Why do humans sleep?  What is sleep’s evolutionary basis? And what is really going on while we sleep?  This week, we broadcast a conversation with cognitive neuroscientist Matthew Walker, talking to Indre Viskontas, originally recorded in 2015.  Walker is an expert in sleep science, and his research reveals that every tissue in the body and every process within the brain is enhanced as we sleep – and impaired when we’re not sleeping enough.  His research also examines the effects of stress, medications, and alcohol on sleep, and the ways we can improve our sleeping habits.

#147 How To Improve Your Sleep and Why You Should with Professor Matthew Walker

Feel Better, Live More with Dr Rangan Chatterjee

Improving the quality of our sleep is arguably the single most effective thing that we can do to reset our brains and recharge our bodies, yet many of us just aren’t getting enough. But what is the optimal amount of sleep and what can we do if we struggle to get enough? I’m delighted to welcome back onto the podcast the world-leading sleep researcher, Professor Matthew Walker to answer these questions and more. Matthew is author of the international best-selling book ‘Why We Sleep’, Professor of Neuroscience and Psychology at the University of California and a fountain of knowledge when it comes to all things sleep.My last conversation with Matthew back on episode 70 of the podcast was one of the most popular to date. A few months ago, I asked my podcast listeners to let me know what further questions they would like Matthew to answer and in this conversation, I put some of those questions to him.We cover how many of us feel that we don’t have enough time to sleep for 7-9 hours but how rather than stealing time from us, getting more sleep can actually make us more productive. And even grabbing an extra 15 minutes of sleep a day will have benefits for our overall healthspan. Matthew shares some brilliant tips on how we can regain control of our sleep and for those who are really struggling, he explains that there is an alternative to sleeping pills that is just as effective in the short term, but much more effective long term.We cover so much ground in this conversation, including polyphasic sleep (sleeping for periods of time throughout the day), unbroken sleep and why lying awake in bed for long periods of time can affect our ability to sleep in the future. Matthew shares the fascinating and dramatic changes that have occurred in the way we sleep and dream following the coronavirus pandemic and why it has allowed what he calls “the revenge of the night owls.”We delve into REM sleep and how it is one of the best forms of therapy – the brain can literally re-wire negative memories when we sleep. Finally, we cover sleep trackers, caffeine and how sleep impacts our immunity. This really is a fascinating conversation, full of fresh insights and actionable tips that we can all put into practice today. I hope you enjoy listening.Show notes available at drchatterjee.com/147Follow me on instagram.com/drchatterjee/Follow me on facebook.com/DrChatterjee/Follow me on twitter.com/drchatterjeeukDISCLAIMER: The content in the podcast and on this webpage is not intended to constitute or be a substitute for professional medical advice, diagnosis, or treatment.

PNTV: Why We Sleep by Matthew Walker (#392)

OPTIMIZE with Brian Johnson | More Wisdom in Less Time

Optimize: https://optimize.me/ (← Get Free Stuff + Free 2-Week Trial!) Optimize Coach: https://optimize.me/coach (← Join 2,000+ Optimizers from 70+ Countries!) Here are 5 of my favorite Big Ideas from Why We Sleep by Matthew Walker. Hope you enjoy! Matthew Walker is one of the world’s leading neuroscientists and sleep experts. He’s a professor at UC Berkeley (and former professor at Harvard) who has spent decades studying why we sleep and how to, as per the sub-title of this book, unlock the power of sleep and dreams. As you know if you’ve been following along, I’m a HUGE advocate of Optimizing our sleep as a fundamental practice in Optimizing our lives. This book has made me EVEN MORE bullish about the power of sleep. The consequences of chronically depriving ourselves of the sleep we need? Well, they’re astonishingly devastating—dramatically increasing the odds of having everything from mood disorders to cancer (and everything else we don’t want). Big Ideas we explore include the fact that you're more likely to get struck by lightning than have the gene that let's you get by on less than the recommended sleep, the universality of sleep (even worms sleep!!), resetting baselines, the iPad effect (did you know how much using one before sleep messes w/your melatonin?), and some tips to Optimize your sleep TONIGHT!!

Matthew Walker's "Why We Sleep" Is Riddled with Scientific and Factual Errors

Nourish Balance Thrive

Back on the podcast with me this week is sleep expert, Greg Potter, PhD. Through his articles, podcasts and live talks, Greg is helping an international audience understand the critical role sleep plays in health and wellbeing. Most recently, Greg has been studying the impact of circadian rhythm disruption, including sleep duration and meal timing, on the development of common cancers. In this interview, Greg and I discuss Alexey Guzey’s scathing critique of Matthew Walker’s book, Why We Sleep. We also talk about some of the biological processes affected by sleep restriction, including cognition, immune health, athletic performance, and appetite. Greg shares some of the ways poor sleep is associated with cancer formation, including the damaging effects of sleep restriction on DNA and metabolism. Here’s the outline of this interview with Greg Potter: [00:00:09] Greg's 4-part series of articles on sleep: 1. Having trouble sleeping? A primer on insomnia and how to sleep better; 2.
