Vagus Nerve Stimulation, Explained
The vagus nerve is the longest cranial nerve in the human body, running from the brainstem all the way down to the abdomen. It is the primary channel of the parasympathetic nervous system — the network responsible for rest, digestion, and recovery.
When the vagus nerve is well-toned, meaning it responds quickly and robustly to signals, you experience faster recovery from stress, better digestion, improved mood regulation, and deeper sleep. Low vagal tone, on the other hand, is associated with chronic inflammation, anxiety, and a host of autoimmune conditions.
TUNE’s technology targets vagal tone directly. The specific vibration frequencies we use are calibrated to resonate with the mechanoreceptors along the vagus nerve pathway. Combined with synchronized neural music, each session effectively ‘exercises’ the vagus nerve, improving its responsiveness over time.
Clinical studies on vagus nerve stimulation have shown promise in treating depression, PTSD, and chronic pain. While TUNE is a wellness tool and not a medical device, our approach draws on the same body of science to deliver measurable improvements in autonomic balance.
