Agreed. It's dangerous. This is simply someone's personal experiment and their experiences written up. It's proof of nothing other than "I did something"
It's so strange to see "independent researchers" attempt to poke holes by any means in an argument meant to protect people from the ill effects of sleep deprivation, yet provide zero non-anecdotal evidence to support lack of sleep being beneficial.
Discounting Walker's argument with "he's not thorough" and then providing a "study" done by one person with no professional research experience appears fine for HN
Okay, he removed the 5 hour bar. I get what the author in your link is upset about, leaving out data points. But imo that's not good enough to make me throw out all the information in that book.
It sounds like the author is upset a book about getting enough sleep is getting so much attention. If they're upset at the way Walker misrepresents information, then I'd hate to see the author's blood pressure while feverishly researching the bias of every article they come across
I wouldn't say this is refuting even a minority of claims in the book. It appears to be a thorough fact check of a small percentage of claims, some of which is going after the author over wording and inconsistencies. It's fair criticism, but by no means invalidates a majority of the information regarding sleep that Walker presents
This 100%. I've read the book twice, coming back to certain chapters more than twice, because it's dense with information. It's scary really. The single most impactful thing you can do as a human for your life is to prioritize 8 hours of sleep per night, full stop.
