Since you have mentioned matthew walker and have read his book, do you know he has misrepresented a lot of data in his book you can check it here https://guzey.com/books/why-we-sleep/ what are your thoughts on it? I think coming to any conclusion based on his book is not correct.

Btw I'm not trying to find fault in your content or anything just giving a different opinion

I just went down a rabbit hole reading Guzey's post & responses to his post. I must admit, I'm doubtful about Matt Walker's data on sleep duration specially. Even though he addressed some of the concerns, he didn't talk about data manipulation, which is not cool.

And his statement on "the shorter your sleep, the shorter your lifespan" seems to be a correlation, not a causation.

I guess I might have been biased to believe Walker's research because I realized I personally do better on ~8 hours of sleep. But I'm not consistent with my sleep times (& duration at times too) which I wrote about and I think I feel fine for the most part except when I push my sleep time too late.

This makes me question some of the sleep data. But I still think that the protocols for improving sleep are effective for the most part. I am though a believer in people self-experimenting because health science is not a one size fits all model and we are too early in the studies to know a lot of the info or extrapolate from animal studies.

So people should discard what doesn't work for them and experiment!

Thanks again for pointing this out!

Hey NJC! Thanks for sharing this and I always appreciate different opinions. This guzey piece is insightful & making me question the sleep data of Walker's research. I'll look into it in more details. Seems like Walker responded to some of the concerns here: https://sleepdiplomat.wordpress.com/2019/12/19/why-we-sleep-responses-to-questions-from-readers/

But, I think the optimization tips for improving sleep still hold. Granted, some of them may not work for some people, and by no means are they absolute truths, but I think a lot of them can be helpful for people looking to improve sleep whether they sleep for 5-6 hours or more. Which is why I tried to focus this point on tips for improving sleep. What do you think?

But it seems like when comes to sleep and longevity data, we need better info. I might edit my post on the sleep duration point based on this info.

I agree that manipulation of data and hyping up certain practices by scientists is becoming something to watch out for. Example: NAD+ precursors have become a hype too and the more I learn about it through my podcast and other data, the more I question media hype. Discussed the NAD+ hype here if you're interested: https://podcasts.apple.com/us/podcast/01-how-to-fight-aging-nad-boosters-senolytics-curing/id1588806541?i=1000538366024

Anyway, thanks again for sharing this, I appreciate it!
