Shallow breathing and living charge

I would be inclined to expect unfelt and unconscious shallow breathing to be part of weaker function. With mouth breathing as a sign of lack of energy. What is 'over breathing'?  (Ok I looked it up).
I've recently adopted the 'nitric oxide dump' 4min exercise from Zach Bush (Mercola brought him on stage at some forum recently and I followed him up). Nose breathing is part of its working and chimes with other things I recently met on not mouth breathing.
When the shoe fits - wear it - but chasing 'health' in terms of externals is a reinforcer of a sense of lack.  Breathing is a core fundamental activity that as with so much else can set up a positive or negative reinforcement loop. Is it not all about where we are coming from? A sense of connection lived or a sense of lack in seeking elsewhere.
I don't know a lot about NO  - and if as I do - it will open a lot more that I don't know or perhaps frame me in presuming to know.
But Zach Bush indicates the first 4 mins or so of a persistent exercise release the NO - after which it takes a couple of hours to replenish (?) - and so don't repeat the exercise again too soon. So this is just me repeating what I heard. Stress-triggering NO opens the flow to more regeneration, repair and robustness to the musculature and vasculature. Sounds plausible. Its all about finding your balance in life or perhaps losing it in habit-forms of sleepwalking through it.

If we were regarded as a living battery we would need charge/discharge cycles to maintain and embody polarity charge. Which is that flowing yin-yang embrace of each within the other and both/all within the whole. In our society, a polarized communication breakdown operates both poles against the centre instead of a centred balance point embracing both (all) polarities. A false centrism denies polarity in risk aversion. Loss of balance in alignment generates an action reaction reinforcement that depletes and exhausts the natural desire to support and embrace it. Everything falls apart without a true rythmic balancing of the centre with its field, and the field with its centre. Control is not top down - except as organised disorder trying to pass off as control. Alignment in unified purpose is a true control. In simple terms this is in the felt qualities of our being that seem cliches to their lip service or masking facade - but joy in what we be and do is not complicated though such purpose lived will inevitable meet all the 'complications' we individually and collectively set up to evade, delay or deny presence in reacting to something passing off as true.
