Why We Sleep: Unlocking the Power of Sleep and Dreams

There is some controversy around this book surrounding the misinformation - but much of it is harmless, just leaps that Walker took for research. Such as his suggestion that lack of sleep causes cancer - which there is no evidence for that (but the point is that it is bad for your health).

But as an OT student, I knew most of the information already. There was very little new information, except at the end with anecdotes, and perhaps the political messages at the end calling for work reform. It is well written enough that the familiar information is enjoyable to read again, but this book does not go deep enough into the science for my liking. It talks more about the implications and results of the science of sleep rather than the neurological reasons. Too much theory for my liking.

I have mixed feelings about this book. I finished reading it and it makes you want to change many of your sleep habits, but at the same time I felt he may have overemphasized certain "facts." If you believe everything word for word it is scary...thus my mixed feelings. But incorporating many of his ideas are without a doubt a good thing.

This book is – spoiler – about why we sleep and the importance of sleep. It starts with theories of why we sleep and dream (it is quite interesting that we still don't really know), how other animals sleep, why we need sleep, why we will surely die an early death if we don't sleep, why society is not set up to accommodate our sleep needs, and then, at the very end, literally 12 bullet points about how to improve your sleep.

I won't argue with the importance of sleep, nor that its importance is undervalued in capitalist hustle cultures. But I don't trust any author that claims one thing will radically change your health. Health is a complex myriad of things, only some of which are in our control.

For me, sleep often feels out of my control. Insomnia is barely addressed in this book, and when it is, it's treated flippantly. Just do some CBT and you'll be good!! The author makes it seem like it's so easy to just sleep more. Sleep does not, and probably never will, work that way for me. For over a decade I've sought the answer to consistent quality sleep. I've tried nearly everything (including CBT), and yet still go through periods of days and weeks (and in some very rough patches, months) where sleep eludes me. Despite all best efforts and having read a bunch of books like this. (Why do I keep reading books like this, you ask? In the dwindling hopes that one will eventually have the key to this particular misery.) I'm beginning to think that it's just genetically hard-wired, and like a chronic disease, all I can do is manage it.

If anything, this book should come slapped with a big warning for insomiacs – this book WILL make you panic if you put stock in its alarmist messaging, so maybe just don't!
