Criticisms of "Why We Sleep"
There was a rather hard-hitting criticism of the book, by Alexey Guzey:
...and a later response to criticisms from Dr Walker here:
Personally I don't think those initial criticisms do nearly as much as Alexey thinks they do to destroy the entire validity of the work. They're more like editor's notes, fixing a bug here and there. I'll continue to take the work of a professional sleep researcher over an amateur like Alexey who writes:
I've been experimenting with sleep for the last month and I converged on a formula of sleeping 4-5 hours per night and then doing as many 20-30 minute naps as I need during the day (1-2 usually).
I hope to write the synthesis of everything I know about healthy and efficient sleep habits in the future.
I'll be looking forward to that.
It is important to know that "Why We Sleep" is not a guide to helping you get better sleep. It gives you so much information about sleep that it can create or exacerbate anxiety, particularly for people who already have sleep-related problems. This is a major issue and thankfully Dr Walker will be putting a note to that effect on the next edition.
I hardly recognise the words above! I have softened a lot in my outlook on these matters.
