who else's brain takes a long time to "warm up" or stabilize after waking?
I suspect this probably varies across the entire population to some degree, but for me it feels like my senses and my mind aren't fully "bound together" properly when I wake up, and it takes a while of being conscious, QUIETLY, for them to come together and be functioning right. This process takes far longer if I'm in a state of serious/chronic burnout, up to several hours.
If I skip it and jump directly into activity, things usually stabilize quicker, but in a crappy muddled way, and much of my day can be off, I feel dumber, forget things, lower threshold for confusion/distress from random events, etc.
Yes. I'm very lucky in that I'm able to spend a couple of hours in my room after waking and don't have to rush to start my day, because for me, rushing to get up and "pull myself together" will lead to a crappy day every time.
