Effect and research

HRV (Heart rate variability) functions as a biomarker in health and disease. It is also the best biomarker to track our longevity.
The chart shows our clinical trial results on HRV, conducted at KRISS. In this double-blind, placebo-controlled clinical trial, we obtained results that showed the activities of the parasympathetic nerves of the autonomic nervous system were increased by over 275% by stimulating the cardiac branch of the vagus nerve.
We have yet to find other neuromodulation technology or medical technology that can change and regulate the parasympathetic nervous system, which controls the body's unconscious behavior and functions, so dramatically within just one day.
