The issue with the critique is that he criticizes "meaningless correlational studies" but still uses them to come up with his conclusion. I do sleep optimization in private practice with CEOs & VC. I rec. 7-8 min, 8-10 with heavy physical/mental activity.https://twitter.com/DrSepah/status/1189694113714622464?s=20 …
Spent 3 hours or so rereading 1st chap of WWS, dug into Alexey's post and papers he cited. Overall points: - MW published some factually erroneous claims, but his message is in the right direction - If you are young & fit you should def sleep ~7.5 hrs https://delian.substack.com/p/d7-sleep-matters-but-alexey-guzey …https://twitter.com/alexeyguzey/status/1195380402078265345 …

I've been thinking about this for the last few days and you're right. Now the conclusion reads: "We have literally no idea about the optimal for long-term health sleep duration." + added explanation Do you have an issue with this or any other parts of the essay? :)pic.twitter.com/CEnBWQ4vHr

More people should be critiquing Walker's book. That is science. If it's "popscience" as you called it, walker should explicitly state that. People are taking it as gospel and that's the problem. People, in general, have a problem with QUESTIONING.

Thanks for saving our time! 8 hours sleep should be heavily promoted. Hopefully, we’ll see more evidence-based, flawless papers/books than the one of MW. The debate reminds the climate change one.

TBH, if any of us wrote a book *that* dense, we might make a few minor erroneous claims.

There is absolutely no way that Matt Walker starred the conversation about the importance of sleep, that ignores over 2000 years of writing about sleep dating back to Aristotle in 350BC
