What it is & how it works
• Nurosym is a non-invasive neuromodulation device that clips onto the outer part of the ear (specifically the tragus) and delivers micro-electrical impulses aimed at the auricular branch of the Vagus nerve (cranial nerve X). 
• The mechanism is described as “auricular vagal neuromodulation therapy (AVNT™)”. 
• By stimulating the vagus nerve peripherally, you modulate parasympathetic nervous system activity (rest-and-digest) and reduce sympathetic overdrive (stress, inflammation, etc). 
Nurosym’s works on
• Stress, anxiety, autonomic balance: Because vagal tone is central to managing the autonomic nervous system, this kind of device might help reduce the stress, dysautonomia, or those who have high sympathetic tone (which can impact skin health, recovery, inflammation).
• Sleep, brain fog, fatigue: The device is promoted for helping sleep quality, reducing cognitive fatigue, brain fog — all of which can be relevant in menopause, long COVID, or fatigue syndrome.
• Inflammation, metabolic health: Some early commentary suggests tVNS (transcutaneous vagus nerve stimulation) could influence inflammation markers, autonomic dysfunction, which might tie into metabolic syndrome, skin ageing, etc.
