The vagus nerve is primarily responsible for the rest/digest function of the nervous system. Low vagal tone results in persistent anxiety, difficulty in relationships, sleep and gut disorders, auditory hypersensitivity, and poor heart rate variability (HRV), known in medicine to be a reliable predictor of disease states.
With improved vagal tone, your nervous system is more resilient. SSP accesses the vagus directly through the muscles and cranial nerves in your ears.
In an SSP session, the recipient listens to music that has been dynamically filtered to enhance certain frequencies.
How does this work? Think about the difference in how you feel listening to a mother’s lullaby versus a person shouting. One has an inherent calming effect, the other is likely to drive you into at least some sympathetic activation (fight or flight). We know intuitively that sound alone can affect our bodies.
SSP doesn’t stop working when the listening ends, either. Just as your muscles are busy rebuilding for hours and days after you lift weights, your nervous system continues working after being gently challenged by the SSP to make positive changes.
