  Author(s): Umesh Pal SinghUmesh Pal Singh
  
  Being a yoga practitioner, Dr. Singh has always been curious to know of how yoga works. First, after going through the book—Nature and Health, he could find that carbon dioxide stimulates vagus nerve. Thereafter he could also find a study that shows of how increased blood concentration of carbon dioxide (hypercapnia) in conscious humans can stimulate the vagus nerve that in turn, manifests as respiratory sinus arrhythmia (RSA). Even more important, the results of this study also prove that when hypercapnia is coupled with exhalation phase, a synergistic effect occurs that compounds the cardio-inhibitory response of vagus nerve. In some review articles, it was stated that increased blood CO2 concentration is the most porobable mechanism that determines an enhanced effect on the cardio-inhibitory response of vagus nerve during exhalation phase of the breathing rhythm.
