One nerve wanders from the base of your skull to your abdomen. It's called the vagus โ and it changes everything. ๐ฎ๐ฎ
Part 3. And this is where it gets interesting. ๐ง
Most people know about fight or flight and rest and digest. But do you know where those systems actually live in your body?
Your sympathetic nervous system โ the one that protects you โ runs through the middle of your spine from T1 all the way to L2/3. Alongside it sits the sympathetic chain, branching directly into your heart, lungs, stomach, intestines and adrenal glands.
When that system is wound up, it changes how those organs function. That's why stress doesn't just feel emotional โ it lands in the body.
Your parasympathetic nervous system โ the one that restores you โ enters from two completely different places.
The top: the base of the skull, where the vagus nerve travels all the way down through your throat, chest and abdomen, quietly delivering the signal that it's safe to restore.
And the bottom: the sacrum, supplying the pelvic organs, bladder and reproductive system.
Sympathetic through the middle. Parasympathetic from the top and the bottom.
Between them, they govern everything your body does without a single conscious thought from you.
Which means your spine health and your organ health are not two separate conversations.
They never were.
Constipation.
Bladder urgency.
Irregular cycles.
Unreliable digestion.
Reflux.
Sleep that doesn't restore.
These aren't random. They're the organs telling you exactly what state your nervous system is in.
A normal organ receiving an abnormal signal will not behave normally.
The question isn't only what's wrong with the organ.
It's what the nervous system is telling it to do โ and what would need to change for that signal to be different.
