As others have mentioned, there seems to be some sort of emotional aspect to this cold adaptation. Having done cold adaptation for quite some time now, I've started to feel more and more of some kind of emotional processing going on after the showers. Just today, after the cold shower (the water here is around 7C), I heard my wife singing and playing the piano in the living room, and I almost started crying because it touched me very deeply.
And, if I have the chance to lay down and close my eyes after a cold shower, I sense these waves of emotions and impassions overwhelming me. Sometimes they are memories of something that happened in the past, sometimes realizations - "aha moments" of understanding of some past thing that happened. This is just my layman's guess, but could it be that the shaking and tremor we experience after a cold shower/bath somehow releases memories and suppressed emotions in the body, from the muscles and tissues?
Absolutely,
From the sounds of peoples experiences we have neurogenic trauma releasing tremors happening. This can be induced in a variety of ways, there is some kind of route through the musculo-skeletal, limbic, vagus nerve, or cold induced through the central nervous system. I haven't quite got my head around it all but the links are clearly there. Animals naturally release and tremor out their nervous system tension after trauma, we humans need a bit of assistance to get the mechanism going again. When we are kept in a fight flight state chronically it is easy to control use our resilience is decreased we are afraid of the shadows.
To sum it up these are the things I think that help us to rid the body of this tension:
1) Ketogenic diet and feeding our healthy gut bacteria, through the gut brain connection
2) Cold adaptation which induces tremoring and raises core body temperature increasing resilience
3)
Neurogenic tremoring instigated by trauma release exercises
4)Body therapies that gently communicate with the central nervous system through fascial proprioception that also creates a trauma/tension release, particularly when focused on the iliopsoas muscle
5)Breathing techniques that stimulate the diaphragm (EE) and relax the oral facial muscles (pipe breathing)
6)Placing the tip of the tongue firmly into the roof of the mount this protects the oesophagus and the throat can open relaxing the oral facial mucles which allow the sphenoid bone to freely move with the cranial-sacral rhythm, hydrating the brain and balancing the endocrine system.
