Professor Matthew Walker is a Professor of Neuroscience and Psychology at the University of California, Berkeley, USA. He is also the founder and director of the Center for Human Sleep Science. If you've got sleep questions, he's your guy. We talked about chronotypes, or the category of sleeper you may fall into. It turns out, whether you're an early riser or a night owl might not actually be your "fault", and in fact it may have been something you were born with. Don't forget to leave a 5 star review with a medical question in the body of it and I'll try to answer it in a future episode!Buy Professor Walker's book, "Why We Sleep" here: https://www.simonandschuster.com/books/Why-We-Sleep/Matthew-Walker/9781501144325Follow Professor Walker here:Podcast: https://themattwalkerpodcast.buzzsprout.com/Twitter: https://mobile.twitter.com/sleepdiplomatInstagram: https://www.instagram.com/drmattwalker/Linked In: https://www.linkedin.com/in/sleepdiplomat/Why We Sleep: https://www.amazon.com/dp/1501144316Executive Producer and Host: Dr. Mike VarshavskiProduced by Dan Owens and Sam BowersArt by Caroline WeigumCONTACT: DoctorMikeMedia@gmail.com
