Not sure how it may sound but, I (not sure for most people) express anxiety in my body. I do feel it in my chest, heart region. And for example a good friend of mine express it in his belly or stomach region.
I was wondering if people here have noticed a correlation between a SPS and a reduced anxiety in this part of their body. Like I am expressing anxiety with a tightnness in the heart area, would something like SPS: Cardiovascular System help?
Anyoe has experience with that?
It depends bro
As a bodybuilder/fitness enthusiast, I can tell you that muscle tightness can cause both stress and fatigue, hence why getting massages regularly is recommended for lifters.
If you’re thinking about treating physical symptoms that could potentially lead to stress, then try to understand first what is causing the physical discomfort.
For example, I used to have migraines all the time, in fact, many people like @Ice @Moon and @GoldenTiger can tell you about an issue I had, where if I slept more than 6 hours, I’d get migraines and feel stressed out and brain fogged, so what did I do? I spent a hella lot of time with APS: Head in my customs, and I reached a point now where I can sleep long without migraines, and no more stressing about how much I can sleep without headaches.
Another thing I’m combatting right now is my digestive system, as it’s one of the things that causes me some anxiety, since my gut is sensitive, and often times, I get late to my plans due to me urgently needing to spend longer on the toilet, so that’s what lead me to add SPS: Digestive, and it’s working well, and I have no stress about it becoming an issue when I’m out.
So if that’s the kind of stress you’re talking about, then add the SPS (or APS) module that would target your specific physical issue, cause the relief will not just help the discomfort, but the stress that comes with it too.
However, if you’re talking about the stress itself causing physical discomfort, then you would be far better with the following combo in your custom:
harmonic singularity (to release tension from body)
The flow (for mental tranquility and peace).
SPS: nervous system (to strengthen your CNS response to stress).
Asclepius (to avoid getting affected by stress in the shape of sickness).
deep sleep (without this, the effects of the stress could drop sleep quality).

I got the same thing with migraine also, so APS: Head can be a thing.
Your post made me realise the overall issue I was adressing is more like stress → body reaction. I am planning a meta sub for everything related to full brain/mind efficiency, emotional balance. As saint’s Revelations sub are not out there yet I am thinking QL + ME + your combo below (SPS: nervous system may be redundant)
Do consider the module Stress Displacement too. Excellent for physical healing/shifting customs.
I second Harmonic Singularity to release tension in the body. I use it in a physical custom to allow for more flow and less tension in movement, but theoretically it would complement modules like Stress Displacement - balancing solutions to physical stress with solutions to mental stress.
