Vagal cardiorespiratory breathing improves fluid intelligence and other organ function

This article is interesting relative to cardiorespiratory resonant breathing.

Buteyko breathing improves asthma because of breathing retaining?

Prayama yoga breathing also improves asthma similarly.

In India diabetes is mitigated by this breathing technique.

In the case below asthma measurably improves.

Stress symptoms are lowered.

Why?

Cardiorespiratory resonant breathing activates a vagal reflex that improves the brain by lowering cortisol and increasing BDNF; it improves organ function by activating the CAP cholinergic anti-inflammatory pathway by releasing acetylcholine into circulation to phenotypicaly shift angry M1 macrophages into M2 status macrophages.  That shift reduces immune stress that degrades cells, tissues and organs.

Vagal nerve stimulation also tunes the ensemble of 5 unique human abilities.

I infer that this "tunes"or connects the human "hive" mind in every individual to improve their fluid intelligence which allows novel problem solving.

Breathing pattern recordings using respiratory inductive plethysmography, before and after a physiotherapy breathing retraining program for asthma: A case report

Breathing retraining (BR) improves symptoms, psychological well-being and quality of life in adults with asthma; but there remains uncertainty as to mechanism of effect. One of the intuitively logical theories is that BR works through altering breathing pattern. There is currently no evidence, however, that BR does result in measurable changes in breathing pattern. In this case report we describe the effects of physiotherapy BR on a 57-year-old female with a 10-year history of asthma. Data were collected before and after a physiotherapy BR program comprising three sessions over 18 weeks: breathing pattern (respiratory inductive plethysmography (RIP); physiology (end tidal carbon dioxide (ETCO₂), heart rate, oxygen saturations, spirometric lung function); questionnaires (Asthma Control Questionnaire (ACQ), Hospital Anxiety and Depression Score, Nijmegen Questionnaire); and medication usage. After BR, the patient’s symptoms improved. Her physiology was largely unchanged, although her FEV₁ increased by 0.12L, peak flow by 21L/min. The patient reported using less Salbutamol, yet her asthma control improved (ACQ down 1.5). Her Nijmegen score dropped from positive to negative for hyperventilation (from 39 to 7). Her anxiety-depression levels both reduced into ‘normal’ ranges. The patient’s expiratory time increased, with longer respiratory cycles and slower respiratory rate. No changes were seen in relative contributions of ribcage and abdomen. Controlled trials are now needed to determine the generalizability of these findings.
