What causes grogginess when you first wake up – what about your brain isn’t working?

When you go to sleep your brain is filled with sleepy juice so that you don’t wake up every time a dog farts next door.

This sleepy juice takes a while to go away once you wake up.

Haha nice, and pretty much spot on, nearly everyone has tried to stay “asleep enough” to go to toilet and then back to bed right? We have that ability all the time, presumably because other humans can guard us, some other mammals are the reverse.

Most areas of the brain will change its output base on “sleep juice ” we really have several types and locations for cognition, sleep makes them all dopey.

Personally, I think sleep makes all these areas come back into timing.

Read “why do we sleep”, etc. Still pretty controversial.

Your sleep is made of two different flavors: the “rest your brain” one and the “reorganize your brain” one. You get woken up in the first one, not good. You get woken up in the second one, good. Each night you cycle over multiple “rest your brain” and “reorganize your brain” phases.

As a narcoleptic I explain it to people like this. When you sleep, your brain turns into a Zelda game. Your levels of sleep are the dungeons. If you go into the first room in a dungeon, and you lose a heart, it’s easy to go right back out and get more health. The further into the dungeon you go, the longer it takes to get back out. Sleep is like that too. If you are in those light beta waves of sleep, it’s easy to wake up again(partners snores wake you up, you hear dog fart and roll over). If you’re in deep stages of sleep, a blaring alarm waking you up will for sure wake you up, but it will take longer for your brain to catch up to that state of wakefulness.

When we go to sleep, our brain goes through cycles. think of it like a big circle, with “check points” where you stop and switch activities. Sometimes we wake up in the middle of that “cycle”, and it’s much harder to skip ahead to “awake” because we are stuck way back in the middle of those checkpoints. During those “stops” we have different states of unconsciousness, and sometimes when we are dreaming (such as REM sleep) it’s much more difficult to “snap” back to being conscious. Our brain has to clean up the chemicals that were helping us stay in that deep sleep state (that helps refresh our brains for the next day), so that groggy period is just our brain catching up because we interrupted the usual cycle.
