He\u2019s also a professor of neuroscience and psychology at the University of California, Berkeley and was previously a professor of psychiatry at Harvard Medical School.&nbsp;<\/p>\n\n\n\n<p>He has published over 100 scientific studies, <a href=\"https:\/\/scholar.google.com\/citations?user=lhjZVXkAAAAJ&amp;hl=en\">mostly on sleep science<\/a>, and has appeared on numerous television programs, including <em>60 Minutes<\/em>, <em>BBC News<\/em>, and <em>CBS This Morning<\/em>.&nbsp;<\/p>\n\n\n\n<p>Beyond TV programs and podcasts, Walker spreads the gospel of sleep through events, forums, and workshops\u2014his <a href=\"https:\/\/www.ted.com\/talks\/matt_walker_sleep_is_your_superpower\">2019 TED Talk<\/a> was one of the fastest to reach a million views, according to his <a href=\"https:\/\/www.sleepdiplomat.com\/speaker\">website<\/a>. His other pursuits within the field of sleep include serving as scientific counsel to companies like <a href=\"https:\/\/www.fitbit.com\/ph\/home\">Fitbit<\/a>, <a href=\"https:\/\/www.sleepdiplomat.com\/entrepreneur\">Google<\/a>, and sleep therapy company <a href=\"https:\/\/www.shuni.io\/\">Shuni<\/a>.&nbsp;<\/p>\n\n\n\n<p>In 2020, <a href=\"https:\/\/news.berkeley.edu\/story_jump\/sleep-researcher-matthew-walker-wins-carl-sagan-science-prize\/\">he won the Carl Sagan Prize for Science Popularization<\/a>, which is given to researchers who\u2019ve made science more accessible to the general public.<\/p>\n\n\n\n<p>Walker\u2019s <a href=\"https:\/\/www.sleepdiplomat.com\/professor\">official website<\/a> states that he earned his Ph.D. in neurophysiology from the Medical Research Council (MRC) in London. However, in a <a href=\"https:\/\/guzey.com\/books\/why-we-sleep\/\">blog post critiquing Walker\u2019s book<\/a>, researcher Alexey Guzey points out that the MRC does not grant Ph.D. degrees. Walker\u2019s <a href=\"https:\/\/en.wikipedia.org\/wiki\/Matthew_Walker_(scientist)\">Wikipedia page<\/a> states that he received his Ph.D. from Newcastle University, and that his research was funded by the MRC. It is unclear why there is a discrepancy in information.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p><strong>Connect with Dr. Matthew Walker:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/www.sleepdiplomat.com\/\">Website<\/a><\/li><li><a href=\"https:\/\/twitter.com\/sleepdiplomat\">Twitter<\/a><\/li><li><a href=\"https:\/\/sleepdiplomat.wordpress.com\/\">Blog<\/a><\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-the-book-s-publication\"><strong>The Book\u2019s Publication<\/strong><\/h3>\n\n\n\n<p><em>Why We Sleep: Unlocking the Power of Sleep and Dreams<\/em>, published in 2017 by <a href=\"https:\/\/www.simonandschuster.com\/books\/Why-We-Sleep\/Matthew-Walker\/9781501144325\">Simon &amp; Schuster<\/a>, is Walker\u2019s first book. It became a <em>New York Times <\/em>Best Seller and landed at the top of the <em>Sunday Times <\/em>Bestseller list in the U.K.&nbsp;&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-historical-context\"><strong>Historical Context<\/strong><\/h3>\n\n\n\n<p>Walker sees insufficient sleep as a global problem, originally writing that the World Health Organization (WHO) even considers it a health epidemic. He has since <a href=\"https:\/\/sleepdiplomat.wordpress.com\/#CDC_WHO\">corrected this information<\/a>, saying that it should have been attributed to the Centers for Disease Control (CDC). (It\u2019s worth noting that the CDC currently doesn\u2019t seem to consider insufficient sleep an epidemic. Blogger Guzey speculates that the source of the error might be <a href=\"https:\/\/guzey.com\/books\/why-we-sleep\/#possible-origin-of-the-sleeplessness-epidemic-thing\">CDC\u2019s modified stance on sleep loss<\/a>, from \u201cpublic health epidemic\u201d to <a href=\"https:\/\/perma.cc\/UJ4W-JHNY\">\u201cpublic health <em>problem,<\/em>\u201d<\/a> though this happened two years prior to the book\u2019s publication.) Walker writes that society doesn\u2019t seem to give sleep much importance in part because science hasn\u2019t sufficiently explained <em>why<\/em> we need it.&nbsp;<\/p>\n\n\n\n<p>Historically, <a href=\"https:\/\/thorax.bmj.com\/content\/53\/suppl_3\/S2\">there wasn\u2019t much scientific experimentation in the field of sleep prior to the 20th century<\/a>, and the \u201cstudy\u201d of the field was largely centered around <a href=\"https:\/\/www.shortform.com\/blog\/how-to-interpret-dreams\/\">dream interpretation<\/a>. Sleep science began to progress in 1952, when researchers first observed the rapid-eye movement phase of sleep. Walker writes that in the last two decades, there has been an \u201cexplosion of discoveries,\u201d a \u201cresearch renaissance\u201d that reveals how sleep works and just how important it is.&nbsp;&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-intellectual-context\"><strong>Intellectual Context<\/strong><\/h3>\n\n\n\n<p>While the book is classified under the genre of popular science\u2014an interpretation of science geared toward a general audience\u2014<a href=\"https:\/\/guzey.com\/books\/why-we-sleep\/#appendix-is-why-we-sleep-pop-science-or-is-it-an-academic-book-also-miscitations-impossible-numbers-and-walker-copy-pasting-papers\">Walker and other researchers have cited it in academic papers<\/a>. (You can find a list of citations on <a href=\"https:\/\/scholar.google.com\/scholar?start=0&amp;q=why+we+sleep+walker&amp;hl=en&amp;as_sdt=0,5\">Google Scholar<\/a>.)&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-critical-reception\"><strong>Critical Reception<\/strong><\/h3>\n\n\n\n<p>Positive <em>Why We Sleep <\/em>reviews say the book is a fascinating, engaging read and that Walker is adept at explaining complex scientific concepts to a general audience. However, even those who give the book positive reviews (including Microsoft founder <a href=\"https:\/\/www.gatesnotes.com\/Books\/Why-We-Sleep\">Bill Gates<\/a>) note that Walker doesn\u2019t always back up his claims with solid evidence.&nbsp;<\/p>\n\n\n\n<p>The most comprehensive criticism comes from researcher Alexey Guzey, whose <a href=\"https:\/\/guzey.com\/books\/why-we-sleep\/\">blog post<\/a> claims that <em>Why We Sleep<\/em> is full of errors and contradictions, exaggerates the problem of lack of sleep, and misrepresents research. His blog post goes through Chapter 1, questioning or disputing the information from Walker\u2019s book point by point. Guzey explains that he spent 130 hours fact-checking this one chapter to give readers an idea of the density of errors in the book. He cautions readers against taking everything in the book as fact. Since the publication of his blog post, readers have sent Guzey other errors that they found. <\/p>\n\n\n\n<p>In a <a href=\"https:\/\/peterattiamd.com\/matthewwalker4\/\">podcast interview where he discusses sleep<\/a>, Walker responds to critics and says that a critical part of good scholarly conduct is correcting errors, and he addresses some of the errors that he found and that other people have pointed out. In a <a href=\"https:\/\/sleepdiplomat.wordpress.com\/\">2019 blog post<\/a>, Walker addresses some of the questions that have been raised about his book and mentions that he released a second edition to correct errors in the 2017 edition. While there is no record of a second edition online, the version this guide is based on does contain Walker\u2019s corrections.&nbsp;<\/p>\n\n\n\n<p>Some readers have noted how <a href=\"https:\/\/guzey.com\/books\/why-we-sleep\/#appendix-the-concrete-harm-done-by-the-book\">reading <em>Why We Sleep <\/em>has made them even more anxious<\/a> about lack of sleep. <a href=\"https:\/\/sleepdiplomat.wordpress.com\/#Miscellany\">Walker addresses this in his blog<\/a> and has included a caveat in the revised version of the introduction that notes that the book isn\u2019t meant to treat <a href=\"https:\/\/www.shortform.com\/blog\/common-sleep-disorders\/\">sleep disorders<\/a> and advises reader discretion.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-commentary-on-the-book-s-approach\"><strong>Commentary on the Book\u2019s Approach<\/strong><\/h3>\n\n\n\n<p><em>Why We Sleep<\/em> includes a huge amount of scientific information, but Walker makes it more engaging by presenting it in layman\u2019s terms and using easy-to-grasp analogies. The result is an educational read that is friendlier and more appealing than an academic paper. However, Walker himself notes that should you nod off while reading the book, he wouldn\u2019t <a href=\"https:\/\/www.shortform.com\/blog\/taking-offense\/\">take offense<\/a> and would in fact be delighted.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Is Matthew Walker&#8217;s Why We Sleep worth reading?
