A Quiet Revolution in Nervous System Health
Our bodies have a distinct system that naturally manages our response to stress to keep us healthy & adaptable. That system is regulated by a largely underappreciated nerve called - the Vagus Nerve.
The Vagus Nerve, also known as cranial nerve X, is a 24/7 two-way hotline between your brain and nearly every major organ: heart, lungs, gut, liver, etc.
Keeping this nerve active is key to keeping us healthy and adaptable.
Why A Stressed Nervous System Can’t Properly Recover
Over 70% of chronic conditions—including heart disease, fatigue, autoimmune disorders, and depression—are linked to chronic stress and inflammation, ie Vagus Nerve imbalance (1).
Persistently exposing your body to stressors (even simple ones like deadlines) may leave you stuck in a survival loop, fight-or-flight dominance, and visible symptoms like:
- Constantly wired or exhausted
- Increased heart rate
- Narrowed focus and anxious feeling
- Slowed digestion
- Short-term immune response
- Slower recovery processes

What causes Vagus Nerve Impairment
Some evidence suggests vagus nerve impairment can stem from various causes, including:
• surgical procedures [25],
• neurological disorders [25],
• diabetes [26],
• chronic stress [25],
• autoimmune conditions [26],
• exposure to toxins and alcohol [27],
• trauma [25],
• post-infection complications [26],
• heavy metals [27].
FUNCTIONAL OR STRUCTURAL
Conditions and symptoms linked with Vagus Nerve Impairment
Some evidence suggests vagus nerve impairment can stem from various causes, including:
• Anxious thoughts, Panic, Trauma [2,3]
• Brain Fog [4]
• Chronic Tiredness [5]
• Cognitive Impairments [6]
• Problems swallowing [7]
• Persistent low mood [8]
• Seizures [9]
• Sleep problems [10]
• Dizziness and Headaches [1]
• Cardiovascular Symptoms: Abnormal Heart Rate [12], Fainting [1], Blood Pressure Problems [13]
• Gastrointestinal Issues: Digestive Issues [14,15], Reflux [16], Gastric paralysis[17], Vomiting and Nausea [18]
• Metabolic and Endocrine Disorders: Obesity [19], Blood sugar regulatigh problems [20, 21]
• Autoimmune and Inflammatory Conditions: Autoimmune Diseases [22], Chronic Inflammation [20, 23]
Quick Timeline of Vagal Stimulation Science
Researchers begin linking vagus nerve activity to heart rate, digestion, and autonomic control.
Electrical Vagus Nerve Stimulation (VNS) concept introduced by Dr. Jacob Zabara to treat epilepsy.
FDA approves implanted VNS for epilepsy and later depression — required $30k+ surgery and carried risks.
Parasym starts a decade-long effort to create a safe, non-invasive wearable VNS—no surgery needed.
Auricular (ear-based) Vagal Neuromodulation Therapy(TM) invented by Parasym to avoid side effects of neck-based VNS like muscle spasms or cardiac issues.
$10M+ in R&D, 50+ studies with Harvard, UCLA & more. Nurosym becomes the most studied wearable VNS, measurably activating Vagus Nerve by 61% within 5 min in placebo-controlled trials.
Hit Your System's Reset Button. Promote Restoration.
Nurosym helps your body maintain homeostasis, balancing your “rest and digest” response, countering "fight or flight" domination.

When it comes to anxiety the papers I've looked at do provide evidence of support that transcutaneous vagal nerve stimulation is effective at improving parasympathetic drive, it can reduce fatigue and personally I've seen this improves my HRV when using this device.

Step-by-Step Breakdown of How Nurosym Works
Step 1
Attach the earpiece
The tragus is the front door to your Vagus Nerve.
It allows Nurosym to gently tap in and engage your autonomic nervous system with laser precision.
Step 2
Activate & Adjust
Important: Adjust the power with every session so it remains a pleasant feeling and not causing you discomfort. Higher level or longer sessions doesn't mean better. Every session is unique depending on the state of your nervous system.
Start with lower levels and shorter sessions, assess, then gradually increase, but always make sure the feeling is pleasant and not causing you discomfort.
An imbalanced nervous system is like having too many tabs open.
Shut down stress circuits
Start anti-inflammatory pathways
Trigger a cascade of therapeutic effects
Improve cognitive & physical performance
Step 3
Feel Instant Calm
You may notice your system winding down, shoulders dropping, leading to a clearer mind within minutes
Activating Your Parasympathetic Tone - The signal travels to a control center in the brainstem, telling the body to shift from stress mode into rest, recovery, and healing.
Step 4
Use 30-60 Minutes Daily
When you apply Nurosym consistently you train your body to naturally favor a parasympathetic rest and digest state and easily shift balance away from sympathetic fight or flight dominance.

Daily protocol to optimize Nurosym for your individual needs
When used correctly, Nurosym may boost parasympathetic activity by over 61% in just five minutes and deliver 2-4x greater parasympathetic activation than breathwork or meditation.
Use Nurosym as soon as you wake up to kickstart your parasympathetic system. This session helps set a calm, balanced tone for the day ahead. Especially useful for those managing symptoms like brain fog and fatigue.
Before/after a stressful meeting, heavy meal, or a tough workout, use Nurosym to reduce stress, aid digestion, or accelerate recovery. Integrates seamlessly into breaks or quiet work sessions.
Use Nurosym as soon as you wake up to kickstart your parasympathetic system. This session helps set a calm, balanced tone for the day ahead. Especially useful for those managing symptoms like brain fog and fatigue.
MORNING ACTIVATION
15-30 minutes
Use Nurosym as soon as you wake up to kickstart your parasympathetic system. This session helps set a calm, balanced tone for the day ahead. Especially useful for those managing symptoms like brain fog and fatigue.
