When you don't sleep enough, your sympathetic nervous system (fight or flight) gets activated. Your heart beats faster, cortisol is increased. If you spend most of your time in this state it seems normal to you. A return to good sleep might initially feel like you're stuck on a lower gear.

It's not low-gear though. I feel bad after 8 hours. Not refreshed, stiff to a point of pain, hard to focus and so so tired like i haven't slept for days. If I manage 5 hours I wake up refreshed and stay like that most of the day. I don't particularly like the whole "quota" system. I want to sleep as much as I sleep without thinking about it too much. Most times my body will just wake up by itself after about 5 hours anyway, before any alarms ring but sometime it doesn't.

  > Most times my body will just wake up by itself after about 5 hours anyway, before any alarms ring but sometime it doesn't. I was there about a year ago. I'm still working on it, but things are improved. The last hours of sleep are heavy on REM sleep, and I tend to get a bit restless during this time. In the past I would just get up and start my day. However, REM sleep is important, and it's worth working towards improving here. Seems like you're a little concerned you're not heeding the scientific consensus. Check out Dr. Walker's book, so you can be more sure of your current state or more informed. The time spent reading the book might produce 10 years more lifespan.

Unless brain fog is everyone's normal state, I disagree. 6.5-7 hours is my optimal amount, if I sleep in and go 8+ I wake up in a haze and stay like that much of the day.

  I got (mostly) rid of the brain fog when I bought a better mattress. Which was rather a surprise as I thought feeling like that was simply one of the things you have to get used to when getting older.

  I wonder if the brain fog is caused by sleeping more, or if something else is causing you to both sleep longer and wake up w/ brain fog on those days.

  I thought that's why most people drink coffee. I optimally sleep ~9 hours every day and start to feel tired if I sleep less for 3-4 consecutive days. I bike to work (and generally tend to go as hard as I can, so heart rate tends to spend a lot of time in Z4 or so). I almost never drink coffee so it takes me 2-3 hours to "fully awake" but I don't think that's unnatural so I don't mind it, I let nature run its course.
