Hydrogen-Enriched Water and Heart Rate VariabilityScientific Research

Abstract:

Background:Research onfunctional water has revealed itsphysiological functions and health-beneficial effects.Accordingly, thisstudyexploredthe effects of drinking an average dietary volume of functional coherentmineral water (FCMW) on blood pressure, short-term cardiovascular variables,fractal heart rhythm dynamics,and salivary immunoglobulin A.

Methods:Fifteenhealthy subjectswere randomized in a pre-post crossover design, selectedthe morning after an overnight fast. Short-term electrocardiography (ECG) was measured before and after drinking either control mineral water (CMW) or FCMWon two separate occasions.Saliva was collected for fourminutes before the start of each ECG measurement. Blood pressure was monitored in five-minute intervalsfor one hour.

Results:Drinking 100 ml of FCMWtemporarily increasedarterial blood pressure at 20 to 25 minutes in the60 minutes post-drinking. Drinking CMWled to a significant reductionin the heart rate, while all-time domain and Power Spectral Density parameters (PSD) were unaffected. Consumption of FCMWresulted in a highly significant difference and decrease in heart rate, and an increase in NN interbeat intervals,and in two of the PSD parameters.A large increase in total power had a significant increasing effect on 2–3-minute oscillations of thevery low frequency(VLF)power, indicating a specific changein theheartʼsintrinsic cardiac rhythm that isfundamental to health and well-being. An extension in mono and multifractalscaling of heart rate dynamics definesa healthy function and non-local adaptability,indicatinga higher capacity to respond to unpredictable stimuli and stresses, a function which improves autonomic stability. The effect on the heart rate and VLF power suggest anefficient cellular metabolismanda stabilizing effect onmucosal immunoglobulin A.Conclusions:Functional coherent mineral waterwith an apparent non-local electromagnetic identitytriggeredin healthy subjectsa sustainablesympathetic responseincardiac VLF power, which is consideredan intrinsichealth-promotingrhythm produced by theheart itselfthataccompaniesadaptive mono and multifractal heartrhythm dynamics.Keywords: functional water, VLF-power, heart rate variability, fractal scaling, health improvement
