The vagus nerve is one of twelve cranial nerves that connect the brain to the heart, the gut, the immune system, and many of the organs. It acts as a line of communication between the brain and the body’s systems and organs. The vagus nerve controls the parasympathetic nervous system. The parasympathetic nervous system (the “rest-and-digest” system) helps control the body’s relaxation responses. When the body is not under stress, the vagus nerve sends commands that slow heart and breathing rates and increase digestion. In times of stress, control shifts to the sympathetic nervous system (the “fight-or-flight”), which produces the opposite effect.
Within moments of placing the NuCalm Biosignal Processing Disc on your left wrist (about three fingers’ width from your wrist, an area called the pericardium meridian), it begins to send a signal to your heart to activate parasympathetic nerve fibers. These fibers transmit the signal to your brain telling it to increase vagal nerve output and begin the process of slowing down. The disc stops your acute stress response and the neuroacoustic software entrains your brainwaves for restoration and relaxation.
