The guzey_arena_0 test could be biased by his skill level improving over time by playing it regularly, though if he was an avid FPS gamer prior to the guzey_arena_0 tests, the asymptotic growth of skill had probably leveled off in time. I didn't see this addressed in the paper outside of this section: "I will give myself a sleep opportunity of 8 hours (23:30-07:30). I will practice the tasks I’m going to use in order…

It looks like he played the game one week before the experiment, during it, and after three days of recovery and did not find a significant difference

Exactly -- practice effects should have been averaged out by this.

You can't fool me, I know this was just an excuse to improve your FPS aim! Jokes aside, really good read. I had similar goals of cutting out sleep when I was younger. I'm curious what the authors mood was throughout the experiment. That's the main thing I've noticed when not getting enough sleep. My output may be good, I may feel engaged, but every second of the day is torture.

Thanks! I didn't notice any effects on mood but I wasn't measuring them either.

Earlier quoted context omitted.

How did you realize you needed to get a CPAP?

not OP, but if you have sleep apnea, you typically snore very loudly. You may not realize you're doing this because you're asleep and alone, but if you sleep with someone, they will definitely let you know something is wrong and a dr will tell you to get a CPAP machine.

It depends on the type. The most common type, Obstructive Sleep Apnea sounds way worse than loud snoring. If you've ever heard it, it's like the person is suffocating while they sleep (because they almost are).

Well, I wouldn't use the word "bullshit" to describe the book. Reading (most of) the book caused me to change my priorities from basically "I don't care about how much sleep I get" to "getting enough sleep is an important priority for me". Presumably you would agree that that is a positive effect.

Sure, I have nothing against getting enough sleep but the book's first 10 pages contain so much misinformation and given that Walker outright falsifies the data in the book (https://guzey.com/books/why-we-sleep/#appendix-what-do-you-d...) I would struggle to call it anything other than bullshit.

Is it just me, but how can this be taken seriously when the author was trying to show no result. While I love self experimentation, publishing it as if it’s valid science is unfortunate.

Yes, I believe that you should take this factor into account while reading my experiment. As I write:

>Lack of effect on cognitive ability is surprising and may reflect true lack of cognitive impairment, my desire to demonstrate lack of cognitive impairment due to chronic sleep deprivation and lack of blinding biasing the measurements, lack of statistical power, and/or other factors.

I discovered that about 1/3 of people can be sleep deprived without any ill effects, which is the bucket I fall in. Another 1/3 will be disgruntled but can function at a lower level, but for the last 1/3, it's catastrophic and can't function at all. That's my wife, and what exemplified this the most was after having kids. She was almost immediately a wreck but I was able to hold together with the lack of sleep and sp…

Does your wife agree that sleep deprivation has no effect on you?

Seeing as I lived about a year on 4 hours sleep, yes. And most especially during the time we had infants, it made a huge difference.
