I feel vindicated in insisting on 8-9 hours every night, and limiting any caffeine (few cups a month at most).
Sleep duration is associated with brain structure and cognitive performance

#32Earlier quoted context omitted.
That's a really interesting take. I stopped journalling because I noticed I was interpolating the missing bits of my memory while writing down the dream. It became more like writing an imaginary story inspired from my dream, then recording my actual dream. But that said, I definitely think this is good way to force myself out of the loop.
Try splashing cold water in your face. Slap your self a few times. Turn on something that makes noise, like music. I would avoid recording your dreams, because it seems to be what got you stuck in the loop in the first place.
The only thing that gets me out of bed is the day/night cycle bulbs my snake needs. I know I can automate turning off the night light and turning on the day bulb, but if I don't automate then I know she's depending on me when my alarm goes off so I have to physically get up, walk to the other room, and flip a couple switches. On my way back, it's very easy for me to sit down at the counter and eat the sandwich I made the night before for breakfast.

#33This stresses me out because I’ve struggled with sleep for quite some time. Feels awful.
Try Meditation. It really helps sleep quality.
Another thing is not drinking caffeine AT ALL. My sleep quality got much better after I stopped drinking coffee. Strangely I can drink as much tea as I want but coffee makes me sleep badly.

#34Don't get anxious. These kinds of studies are almost always overturned by another one within 12-24 months. Weak correlations are not worth worrying about.

#35I'm bipolar so I've gone through periods where I sleep 18 hours a day and periods where I sleep 2 hours a night if at all. Caffeine intake doesn't seem to matter. Medication and good mental hygiene helps a lot with this issue.

So you're drinking caffeinated or non caffeinated tea?

#37Sleeps helps consolidate anything you learned during the day, since it helps forming long-term memories.
Another interesting theory: dreams are to prevent overfitting and improve generalizability

Re: Sleep duration is associated with brain structure and cognitive performance
#38Interesting. I found after some trail and error that I'm more rested and perform better on less than recommended 8h of sleep. My sweet spot is somewhere around 7h. Fitbit "magic" sleep score also seems to confirm that (better sleep score on less sleep). I also found that stress is the biggest factor in getting good night sleep. When stressed I can sleep 8h and still feel bleh.
I wonder if 8h of sleep is the cause of the better performance or they both are a result of less stressful life, better health or something else.

#39Is this study saying that more than 8 hours of sleep correlates with negative effects on cognition?
Re: Sleep duration is associated with brain structure and cognitive performance
#40Oversleep can also be bad along some dimensions: > For cognition only, associations shift to a negative association of sleep duration and cognition for participants sleeping more than 8 hr a day. Though looking at the charts from the study I can say that Nassim Taleb would not be pleased with how weak the correlations seem to be: https://onlinelibrary.wiley.com/cms/asset/545fd00f-8924-4047...
From table 1, the largest significant correlation coefficient is 0.135. This study can be safely ignored.
agreed. this seems far too low and smells more of p-hacking.
