Thanks for the review!
I am only halfway through the book, but I am already firmly resolved to highly prioritize 8 hours of sleep each night.
I would encourage everyone to read the book while experimenting with getting enough sleep consistently (e.g., for a week), and see for yourself whether the short-term benefits are worth it.
Maybe my assessment is not accurate, but it seems to me that "8 hours of sleep each night is extremely beneficial (relative to other stuff you could do)" is not a mainstream belief among Less Wrong readers. (Though I could find examples, e.g., http://www.thebayesianconspiracy.com/2018/06/61-biohacking-101/ and https://www.lesswrong.com/posts/KsrTZtu48qdkAeSht/a-few-tips-on-how-to-generally-feel-better-and-avoid .)
I would love to hear that I am completely wrong here, but... (read 474 more words →)
In chapter 7 (Too Extreme for the Guinness Book of World Records) Walker mentions a research by David Dinges which seems kind of similar to what you described. I didn't find a reference in the book, but I found this highly cited paper, which seems to me like the one he was referring:
The Cumulative Cost of Additional Wakefulness: Dose-Response Effects on Neurobehavioral Functions and Sleep Physiology From Chronic Sleep Restriction and Total Sleep Deprivation
https://academic.oup.com/sleep/article/26/2/117/2709164
Walker mentions a research by Gregory Belenky with almost identical results that was published around the same time. I found a highly cited paper which seems to me like the one he was referring:
Patterns of performance degradation and restoration during sleep restriction and subsequent recovery: a sleep dose‐response study
https://onlinelibrary.wiley.com/doi/full/10.1046/j.1365-2869.2003.00337.x
TL;DR
Walker has a sub-title "you do not know how sleep-deprived you are when you are sleep-deprived" in chapter 7, so you can guess what the researches above found.
No thanks. Knowing I helped you out is exactly the right reward for me :)
