Living with constant exhaustion is exhausting—but you are not the problem
We hear every day how unpredictable surges and fragmented sleep drain your energy. StVNS was designed for the moments when you are tired of explaining your symptoms and just want relief.
Racing thoughts, dizziness, and mental fatigue derail your day even after months of lifestyle adjustments.
Wearables raise alerts, but you still have no clear protocol for when and how to intervene.
In-person wellness centers require travel, waitlists, and out-of-pocket fees that add more stress.
Every flare feels unpredictable—you crave a repeatable routine that your family and care team can follow.
There is a calmer way forward.
There is a better path
Meet StVNS: Nerve balance therapy that respects your biology
StVNS is a complete care stack: intelligent gentle ear stimulation hardware, soothing immune support, and clinicians in your pocket. No more guessing which protocol to follow or whether today's session is actually working.
Adaptive stimulation, personalized daily
Amplitude, pulse width, and waveform are auto-adjusted from your biology baseline, not one-size-fits-all factory defaults.
HOCl synergy soothes and cleanses
Premium soothing care lowers body stress so nerve balance therapy can work on a calmer terrain.
Remote clinical team inside Health Chat
Licensed professionals review your data, coach each session, and update scripts inside a HIPAA-compliant workspace.
How StVNS guides your body reset
We combine clinical oversight with data to keep every session safe, repeatable, and effective.
01. Wellness tracking
Complete a remote assessment, sync HRV and sleep data, and outline the context that triggers your symptoms.
02. Guided stimulation windows
Follow 8-12 minute gentle ear stimulation scripts paired with breathwork and soothing immune support routines to calm stress urges.
03. Review & iterate
Weekly reviews with clinicians validate gains, adjust parameters, and add new micro-intervention stories as you progress.
Feel the difference in your daily life
Life-changing shifts happen when your nervous system finally gets consistent, targeted relief.
Sleep deeper within two weeks
Participants recorded a 41% increase in deep-sleep minutes by day 14, easing nighttime racing heart and panic spirals.
Restore calm focus mid-day
HRV-guided micro breaks expand focus windows to 120+ minutes, turning reactive afternoons into productive sessions.
Stabilize heart rate and breathing
StVNS protocols promoted more stable relaxation patterns and reduced shortness of breath episodes in wellness cohorts.
Build confidence with measurable gains
Session reports visualize progress so you know exactly which routines deliver relief and when to scale.
Feel supported between appointments
Health Chat integrates voice notes, mood logs, and clinician responses so you are never alone in the journey.
Designed for regulated environments
Every protocol includes verification steps, emergency thresholds, and documentation ready for institutional review.

StVNS vs. traditional approaches
Frequently asked questions
Still curious? These answers cover the most common concerns from patients, families, and clinicians.
Who is a good candidate for StVNS?
Adults experiencing regulation issues, chronic stress, post-viral syndromes, or post-surgical body imbalance who need a structured, clinician-guided nerve balance program.
How quickly can I start?
After a remote assessment and safety screening, most participants receive hardware, soothing immune care kits, and onboarding within 72 hours.
Does StVNS replace my current care team?
No. We collaborate with your physicians or therapists, exporting reports and inviting them into the Health Chat workspace when you grant access.
What does an average session look like?
You attach ear electrodes, follow a guided breathing script, run 8-12 minutes of stimulation, and complete a short soothing immune support routine. Health Chat walks you through each step.
Is the stimulation painful?
Most users describe a mild tingling or warmth. The device auto-calibrates to keep you within clinically proven comfort and safety ranges.
Can I use StVNS alongside medication?
Yes, but we coordinate with your prescribing clinician. Protocols include medication checkpoints and flag potential interactions.
What happens if I miss a session?
The session intelligence engine adapts and the care team checks in. You will receive a revised plan to ease back into the rhythm safely.
Is my data secure?
All data is encrypted in transit and at rest. Health Chat is fully HIPAA-compliant and audited annually by third-party security partners.
Do you work with insurance?
We provide superbills and documentation for out-of-network reimbursement. Enterprise agreements are available for clinics and employers.
What support is available after onboarding?
Weekly clinician reviews are included in guided plans, plus on-demand chat Monday through Saturday and emergency escalation pathways.
