The ear's tragus - the only location proven to reach the brainstem.
What causes Vagus Nerve Impairment
Some evidence suggests vagus nerve impairment can stem from various causes, including:
FUNCTIONAL OR STRUCTURAL
Conditions and symptoms linked with Vagus Nerve Impairment
Some evidence suggests vagus nerve impairment can stem from various causes, including:
Nurosym helps your body maintain homeostasis, balancing your “rest and digest” response, countering “fight or flight” domination.

Use Nurosym as soon as you wake up to kickstart your parasympathetic system and fortify resilience against daily stressors. This session helps set a calm, balanced tone for the day ahead. Especially useful for those managing symptoms like brain fog and tiredness.
Study Participant Outcomes
Onset time: Feel visible results in as little as 5 days*
5 Days
Improved Mood + Energy*
2 Weeks
Lower Stress Levels + Better Sleep*
4 Weeks
High HRV + Accelerated Recovery*
3 Months
Gut + Chronic Symptoms Improvement*
*Results in study populations, individual results may vary
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.
“I could lift my arm. Walk to the bathroom. Eat sitting up. It felt like my body finally got the memo: you’re safe… There’s no single cure. But there are ways to help your system shift out of chaos—and into something quieter, steadier. For me, that changed everything.”
“I remember doing a session late in the day before seeing friends. For the first time in months, I felt stable. That was huge. I use it alongside meditation, either together or one after the other. It became part of my daily routine.”
“I end up finding myself in balls of stress. Since Nurosym, the biggest benefit I’ve had is about my mood and how I approach stressful situations. It just makes it easier.”

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.
