The 2 most basic balancing strategies I've come up with are 1)getting more sleep and rest intermittently with getting adequate exercise, and 2) fasting--or at least not snacking-- intermittently with eating well. But others such as walking outdoors, early morning sunlight, deep breathing, meditation, yoga and socializing may all tend to support better parasympathetic tone.

And I would love to understand more about the vagus nerve and heart rate variability. Not having access to a vagus stimulating device, I have attempted to improvise my own vagus nerve stimulation through singing, long exhalations and occasional Valsalva maneuvers, but I have no way of assessing the effect. Just a hunch, really.
Sticking your head in a bucket of Ice water works well for vagal tone for about the next 30 minutes.

Re sympathetic tone: Ive had a breakthrough there.
It relates to the neck- which was still tight on the back right- and I had an abnormally strong R sided sympathetic response.

I finally got the neck to behave (the problem was lack of movement on the R side- leading to a cascade up to the right cortex, leading to a descending lack of activity passing through the pontomedullary reticular formation and a failure of suppression of the right intermediolateral column in the spinal cord.

The IML is a column of 'always on' cells in the sympathetic nervous system that suppresses the parasympathetics and relies on suppression from the same side PMRF.

This is a huge shift, and I immediately (well withing 10 minutes) found the sympathetic tone dropped and my fingers warmed up.
Im sure this is of wider importance.

Its explained in better detail here:
