5.0 out of 5 stars Trust Me, Don't Mess With Sleep
Reviewed in India on 7 August 2019
Sleep is a mystery. And this book is a lifesaver.

For normal folks like you and me, and for doctors or scientists as well, sleep's been always a mysterious phenomena. We humans sleep (preferably) one third of our whole life. This is an enormous amount of time which demands some attention. Though historically the attention has not been allotted to sleep it deserves, academically or culturally.
If you read this book (and you should; whether you love or hate or enjoy or avoid or have problem with or have some queries on sleeping) you'd understand why the evolutionary process didn't eliminate sleep from our biological dictionary. Why, though seemingly unnecessary/time-wasting/futile/unproductive, we still need to get a good night's sleep to get a long list of physiological, biological, psychological benefits. And if you by any chance fail to get the necessary amount of sleep (voluntarily or otherwise), you're a big gambler who doesn't have the idea about the grave repercussions. (No kidding.)

This book will be beneficial to everybody except those smart dudes who have unwavering faith in some generic and prejudiced sayings like: "Six hours of sleep is enough for a functional adult" or "You'll have chance to sleep all you need when you're dead" or "Our great leader sleeps only four hours/day, hence I should do the same to be like him." etc.

Don't trust them for Kumbhkarna's sake. Don't mess with sleep.

Some curious takeaways from the book:
● Not only the starting phase of sleep is important, when you're going to wake up in the morning is equally significant too. If you get up earlier without fulfilling your sleep-quota, there will be consequences. Serious consequences.
● Melatonin doesn't make you feel drowsy; it just reminds your brain, "Time to go to bed, fella." Part of a whole set of timekeeping mechanism actually. The chemical substance which in fact pressurize your system to make you feel sleepy is named Adenosine.
● Dreaming makes you more visionary/creative/shrewd, really. And dreaming is not just some "commercial breaks" between slumber, it has serious impact on your mindset/thinking/worldview/self assessment and many things more.
● Homo sapiens is "biphasic" in case of sleep requirement. That is, we humans are biologically inclined to get sleep two times a day. Taking a siesta is not just a cultural phenomena in origin, but deeply biological. Dozing after lunchtime is absolutely human-like, nothing shameful if you think so.
● It's not mere practice that makes a person perfect. Practice, followed by a good night of sleep is what required for perfection. And the writer is serious about that.
● You can sleep as many hours trying to recover/make up the sleep that you've lost or skipped; but make no mistake, humans can never "sleep back"/rebound the sleep once lost.
● "Night owls" are real, not myth. As real as the "Morning larks" are. Don't bully them; or feel guilty of being one.
● Caffeine is the most widely used (rather abused) addictive psychoactive stimulant drug in the world. It is also the only addictive substance that we readily give to our children and teens.
● And a lot more.
