I remember seeing a video of a scan of someone in REM. The brain was flushing/washing itself with cerebrospinal fluid whilst the person being scanned was asleep.

First stage was blood draining from the brain and then the fluid washed in and out in waves to clear some of the accumulated “debris?”.

Our bodies are incredible.

First time I saw that I was a bit sad for myself. My sleep is horrible and all the various stuff I've done hasn't done a good job of fixing that issue (including doctors).

Check out the YouTube channel 'the sleep coach school.' The guy also has a book if you prefer. It was the only thing that worked for me.

Also cardio fixes a lot of the issues caused by sleep deprivation. It's hard to get in the gym or go for a run when your exhausted but it's important

Have you looked into /r/DSPD if that applies?

I was not so patient to wait until blue wave. After how many minutes does it come on this presumably gif image?
