Meridian energy analysis of the immediate effect of coffee consumption

IntroductionCoffee consumption has immediate physiological, behavioral, and subjective effects. Despite its widespread use, few studies have described the impact of energy distribution and transformation in meridian vessels. The purpose of this study was to use a Ryodoraku instrument to measure the changes of meridian electrical conductance in healthy volunteers before and after coffee consumption.MethodsIn thirty-one healthy volunteers, the meridian electrical conductance, blood pressure (BP), heart rate (HR), and index of sympathovagal balance were continuously recorded before and after drinking a cup of instant coffee.ResultsStatistical analysis showed that 30 min after coffee consumption, the mean values of electrical conductance increased on most meridians except the bilateral Triple Energizer, Liver, and Stomach, as well as the left Kidney and Large Intestine. From 30 to 60 and 60 to 120 min, the electrical conductances were maintained significantly only on the bilateral Spleen, Urinary Bladder, and left Pericardium meridians, as well as on the bilateral Spleen, Urinary Bladder, and right Kidney meridians, respectively. The average index of sympathovagal balance decreased significantly at 30 min, while BP increased and HR decreased.ConclusionThese findings suggest changes in the specific energy distribution and transformation in the meridian vessels after coffee consumption. Coffee consumption has a similar immediate effect on the cardiovascular system, including increase in BP and decrease in HR. Interestingly, coffee has a temporary stabilizing effect on the higher index of sympathovagal balance. This response may explain why the index is not relevant to the autonomic nervous system but is relevant to mental tasks after coffee consumption.
