Yes, you can read about these things elsewhere, too, but I still think the book is a tremendous introduction to the subject.
But I don't have an academic interest in the subject, so the criticisms in the article do not matter much to me (except for some uneasy feeling about accuracy in general). If you're a student of medicine, cognitive sciences or whatever, you should probably get your introduction elsewhere anyway.
Why do you believe that his representation of research on REM/NREM, light and deep NREM sleep is scientifically accurate?
Why do you believe his representation of effects of coffein and sleep medication is scientifically accurate?
I cover this in sections 14.3 and 14.4: https://guzey.com/books/why-we-sleep/#appendix-common-object...
I read his book and one of the points he made was you could never "make up" missing sleep.
For example, if you pulled an all nighter, you couldn't make it up the next few days if you slept more. Basically the health effects of missing a day of sleep would affect you for the rest of your life.
That was a quite shocking. Were you able to find any information on whether he was exaggerating this?
It doesn't matter if some of the information is correct - once untrue things are peppered in, all facts from the source are suspect and who knows which incorrect facts your brain has.
You've clearly put a lot of time into your research as your post cites. But you don't have twenty years experience in the field. Why should we believe your analysis? Your criticisms could also be tangential or taking things out of context.
"Sleep or you will die"
That grabs readers' attention. While the hyperbolic tone of the book can be justified given that sleep is so misunderstood ... it does invite skepticism at the same time so I appreciate that the author of this article has done such a thorough lookup.
