What does Nurosym do

How does Nurosym achieve all of this?
Vagus Nerve science is well established and Nurosym is a wearable device that is scientifically proven to modulate the vagus nerve via precise electrical impulses that are sent through the skin to a branch of the nerve on the outer ear that projects to the brain. Modern science has discovered that many persistent mental & physical symptoms are linked to a chronically dysregulated nervous system. The nervous system and one of its largest nerves - the vagus nerve - controls critical bodily functions, from breathing, heart rate, digestion to energy management, calmness and mood. When the vagus nerve is not functioning properly, symptoms can surface that relate to these processes (e.g. chronic tiredness or chronic stress). By signaling the nervous system in a natural way through modulating the activity of the vagus nerve, Nurosym helps to bring the body find back to its healthy state and manatin it in balance.
In this way Nurosym can support mental and physical health, helping alleviate symptoms arising from dysregulation in the nervous system.
Nurosym exerts its effects through various mechanisms:
Nurosym has been validated in 50+ completed scientific trials, third party tested and certified to the highest standard of devices that send signals to the vagus nerve. Nurosym was developed by Parasym, a world leading neurotechnology company, and uses Parasym’s proprietary Auricular Vagal Neuromodulation Therapy (AVNT)™ which has been studied in partnership with leading scientific research institutions including Harvard and UCLA.
Nurosym is the most scientifically validated device for targeting the vagus nerve via the ear available without prescription. It is the most studied neuromodulation system of this kind, widely considered as the gold standard by doctors and researchers.
Symptoms studied
Parasym’s AVNT technology has been scientifically studied in 50+ completed studies across a broad spectrum of populations and health and performance applications.
A focus of scientific studies has been on dysregulation of the autonomic nervous system. These symptoms have been linked to autonomic nervous system imbalance and vagus nerve impairment:
Our latest research data also suggests Nurosym improves learning, short-term memory and cognition.
Nurosym has been shown to promote relaxation, mood, sleep, healthy digestion, and increase HRV. Improved stress management alleviates symptoms of stress, burnout, and adrenal fatigue.
Parasym research is also investigating the impact of Auricular Vagal Neuromodulation Therapy on athletic performance, muscle recovery, weight management problems, substance dependency and more.
If you’re not sure if Nurosym is for you, consult with your health professional or contact support.

“Nurosym seems to have had a positive impact on me. I am happy to say that the intervention seems to have been effective.”
James Gill
Doctor
“I have been very pleased with my Nurosym. Before receiving it, I had not been going out much and had not driven for months. Within a few weeks, I started going out for coffee with a friend, managing more around the house, and even driving again locally. A further benefit is improved sleep.
When I bought this wearable device, I did not know what benefits to expect and it exceeded my expectations. I would happily recommend it to anyone with a diagnosed vagus nerve disorder and depressive states or anxious thoughts.”
Pamela
“With Nurosym, I reach my best scores every day. My HRV increased from around 120 to 150–155, and my sleep quality improved.”
Tanya Boychuk
Professional football player
“I have chronic tiredness and post-viral fatigue, which led to persistent depressive states, impulsivity, and high stress. I have been using the Nurosym wearable device daily for several months and felt significant improvements in my symptoms.
The most noticeable change was a major drop in stress levels. My sleep quality, heart rate variability, and resting heart rate also improved. I also noticed an improvement in my mood. While using the device, I usually combine it with breathing exercises to further support calming the nervous system.”
