I am an editor for one of the most visited natural health sites and as such had an opportunity to review a prepublication copy of this excellent book. Sleep is one of the most under rated health strategies and if you haven’t ever taken a deep dive in how to understand and optimize your sleep this is one of the best resources out there to optimize your sleep.
Are you tired? If your answer is yes, it would seem relatively straightforward to assume you're not getting enough sleep. Yet, signs of sleep deprivation may not always be this obvious (and there are other factors besides sleep loss that can make you feel fatigued).
Dr. Walker does an outstanding job of helping you understand the mystery of why we sleep and unravels some of it mysteries, like why your brain shuts down motor control to your muscles during the most active part of sleep, REM sleep. During REM sleep, there is a nonstop barrage of motor commands swirling around your brain, and they underlie the movement-rich experience of dreams. Thankfully Nature tailored a physiological straitjacket that forbids these fictional movements from becoming reality which protects you from harming yourself. Your brain paralyzes your body during REM sleep so your mind can dream safely.
Dr. Walker also consults for many professional teams and helps their athletes understand how sleep is one of the most sophisticated, potent, and powerful—not to mention legal—performance enhancers that has real game-winning potential. Sleep can radically reduce career or season ending injuries and massively improve performance if optimized correctly.
On the downside he reviews the dangers of what most of us do every night. Not sleep enough. This coming week, more than 2 million people in the US will fall asleep while driving their motor vehicle. That’s more than 250,000 every day, with more such events during the week than weekends for obvious reasons. More than 56 million Americans admit to struggling to stay awake at the wheel of a car each month. As a result, 1.2 million accidents are caused by sleepiness each year in the United States. You may find it surprising to learn that vehicle accidents caused by drowsy driving exceed those caused by alcohol and drugs combined. And if you happen to be drinking or using drugs the results are not additive but synergistically exponential radically increasing your risk of an accident, injury or death.
These are only a few examples of the highly useful information you will receive by reading this book. Highly recommended.
