You’ve probably heard these nervous system terms before. But what do they actually mean?
Regulation. Dysregulation. Fight-or-flight. Hyperarousal. Neuroplasticity.
These aren’t just clinical words.
They can help explain why you can feel exhausted but still unable to sleep, calm on the outside but constantly “on” inside, or find it difficult to truly relax even when nothing is wrong.
Sometimes, the brain and nervous system have simply been under stress for too long.
And that doesn’t mean you’re broken.
Your brain is constantly learning from the patterns it experiences—and with the right support, it can learn new ones.
Save this post for the next time you hear one of these terms, and comment BRAIN if you want to learn more about how your brain and nervous system work.
