How to regulate your nervous system in 2 minutes:

It really comes down to just noticing what you're doing, why you're doing it, and remaining calm

Do anything physical Go out in the sun/ nature Take three deep breaths Smile Remember this too shall pass.

I'm tellin' ya, any kind of housecleaning will do the trick.

I used to have a constantly elevated heart rate. But once I started calming my nervous system, I noticed my resting heart rate dropped and I began falling asleep much faster

Slowing everything down was what settled me when I was in a state of psychosis following a psilocybin experience. I stared at everything like I was a newborn. Then came surrender. I accepted that perhaps the worst had happened after the mushroom trip and there was no way I could get back to normal, "so how can I best live my life now?" These 2 things brought me out of the psychosis and into a brief 2 hours of bliss. Everything was exactly how it was meant to be- no more, no less.
