I recommend learning more about sleep. Here's a book that takes a deeper dive.

I have no affiliation with the authors of the book or any of their case-studies.

"Why We Sleep" https://www.amazon.com/Why-We-Sleep-Unlocking-Dreams/dp/1501...

"Matthew Walker's "Why We Sleep" Is Riddled with Scientific and Factual Errors" - https://guzey.com/books/why-we-sleep/

"Alexey Guzey’s Theses on Sleep gained a lot of popularity and acclaim on LessWrong and among people I follow on social media, despite largely consisting of what I think were weak arguments and misleading claims. I found that a bit surprising, so I decided to write a post pointing out several of the mistakes I think he’s made, and reporting some of what the academic literature on sleep seems to show." - https://www.lesswrong.com/posts/sbcmACvB6DqYXYidL/counter-th...

Natália Coelho's post on Guzeys criticism of Matt Walkers book is scuffed with inaccurate methodologies, and redundant circular arguments, counter to popular understanding of sleep mechanisms

(I'm kidding, but I couldn't resist pointing out how meta the dialogue around sleep has gotten)

This is true, and the guy has actually now given up on most of his “you don’t need to sleep” stuff.

However a couple of the scientific errors he found in the original book were truly egregious.
