Can you actually reset your vagus nerve? No. But you can retrain it. Quick hacks change the weather: how you feel in the next ten minutes. Daily practice changes the climate: how your nervous system responds six months from now. In Episode 10 of LVL UP, Lawrence van Lingen explores the vagus nerve, the four states of the nervous system, and the difference between temporary relaxation and lasting changes in nervous-system regulation. We examine what the vagus nerve actually does, why heart rate variability doesn't tell the whole story, and how walking, breathing, sleep, movement and aerobic training can help build a more resilient nervous system. The conversation also examines the science of vagus nerve stimulation, including implanted medical devices, transcutaneous auricular stimulation and the emerging research on exercise, heart function, recovery and inflammation. Topics include: State change versus trait changeThe four states: flat, regulated, wired but tired, and flatlinedHeart rate recovery, resting heart rate and HRVCold exposure, humming and box breathingCoherence breathing, walking in nature and progressive muscle relaxationCrawling, the pelvic floor and movementImplanted vagus nerve stimulation and Kevin Tracey's inflammatory reflexEar stimulation, individual responses and the current researchHow to conduct a 30-day Nuropod experimentThe aim is to understand what creates lasting change, while separating established science from promising research and popular claims.

Vagal branches were historically cut to treat ulcers.Rheumatoid arthritis implant trial: 35% versus 24% with sham at three months; approximately 53% at 12 months after crossover, not complete reversal.Serious device-related events occurred in 1.6% of participants in the arthritis trial. They were surgery-related and resolved.Ear stimulation has not been shown to increase cardiac output. One study found it unchanged despite increased stroke volume.The exercise study involved healthy adults outside exercise programs, not athletes.The sheep study used an experimental pacemaker, not a vagus nerve implant.Kevin Tracey's personal use of cold showers or ear stimulation could not be confirmed.Parasympathetic outflow comes from the brainstem and sacrum. The ganglion impar is part of the sympathetic chain.gammaCore is FDA cleared for migraine and cluster headache.Jonny Wilkinson's 2003 World Cup winner was an extra-time drop goal, not a penalty.NUROPOD AFFILIATE DISCLOSURE I'm an affiliate of Nuropod (Nurosym in some regions, both made by Parasym).
