Does anybody else have this pattern of high stress, stress recedes, body collapses?
Pretty much everyone. Because that’s how the immune system functions.
It’s not quite a binary system, the sympathetic & parasympathetic nervous systems... as there is
some gradient to
some extent... Because they can’t both be on at the same time / switch from one system to the next; the gradient only happens AS they’re switching....but it’s easier to think of as binary. So for right now we’re just goin to oversimplify a smidge.
Sympathetic Nervous System - Fight Or Flight
Parasympathetic Nervous System - Rest & Digest
The SNS is only ever meant to kick on for relatively short periods of time, whilst the parasympathetic runs the rest of the time, taking care of daily living... digesting food/converting it to energy, immune system fighting off infection, etc. The parasympathetic system uses a TON of energy. Just the act of sitting rather than laying -much less standing or walking around- uses the absolute most energy. Digestion uses up 80% of the rest <<< Which is why when you’re sick? Those are the first 2 things to go, as the body shuts those individual systems off and sends all of the energy to the immune system itself. Feeling slow/lethargic? Not being hungry? Aren’t actually symptoms of the infection, they’re symptoms of your body fighting the infection. As are your bones aching, as that’s where we manufacture b-cell antibodies :wtf: and a whole bunch of other fun things>>> But the immune system is still part of the parasympathetic Nervous System. Shutting off digestion and ratiocination are in its purview.
What happens when the sympathetic nervous system kicks on?
The immune system shuts OFF.
Because the Parasympathetic Nervous System shuts off when the Sympathetic turns on.
Which is a damn good thing. It doesn’t matter if you’d recover from pneumonia a week after the bear ate you, or if your cut heals a day faster when you’ve drowned in a flood.
The sympathetic is KING. When it says jump, everything else is already up in the air shouting “How high?”
99:100? A person can be on their deathbed, but leap out like a kid on Christmas morning, if the room catches on fire or soldiers rush in or the river breaks its banks. Energy RUSHES through them, their minds sharpen, and for a very very brief period of time... they’ll feel completely healthy. Better than completely healthy. Because the fight/flight response comes loaded with not just adrenaline, but endorphins/pain killers, a massive blood/oxygen dump.... all systems flooded with NOW!!! Shaaaazam.
It’s meant to turn on several times a day, no worries. Going for a run? To the gym? Playing sports? (Hunting?) Your sympathetic nervous system is what’s in control. That’s why if you’re starting to get sick, you’ll get sick faster... or starting to get better you’ll relapse if you do too much too soon. (Immune System shutting off for even short periods of time gives invaders the edge). But most of the time we aren’t sick. It doesn’t matter if the immune system shuts off for an hour or six. It turns right back on and catches back up killing things once we quit exercising.
You can see where stress creates a problem with this (mostly) binary-system, right?
1. Sympathetic Nervous System on for too long, means the immune system is OFF for too long. Trifling colds blow up into much bigger threats.
2. We don’t FEEL sick, even when we are, because most of “feeling” sick is the immune system itself working hard. Slowing us down, cranking out antibodies, doing it’s job.
So the end result is that we’re a lot sicker than we feel, for a lot longer, and the infection is a much bigger threat... when it’s blown in during times of high stress. Then we either relax (OR the infection has become life threatening to the point the sympathetic acquiesces) and BOOM. The immune system turns on and kicks us on our ass. Because it’s got a shit ton of work to do, that it’s massively behind on.
