What can I achieve with Nervio

With Nervio you can:

Support your body’s natural self-regulation by helping counter nervous system dysregulation.

Build stress resilience, recover faster from stressful events and reduce mood fluctuations.

Reduce post-viral symptoms such as ongoing fatigue or cognitive sluggishness.

Support healthy HRV levels, recovery, and cardiovascular balance.

Relax your mind and stabilize your emotional state, helping you fall asleep faster, sleep deeper and wake up clearer and more energized.

Improve digestive function by supporting healthy communication along the gut–brain axis.

Reduce inflammation-linked discomfort, helping your body maintain a balanced physiological state.

Strengthen cognitive performance and focus, supporting long-term brain health.

How does Nervio work inside my body?

Nervio’s neuromodulation is believed to exert its effects through multiple physiological pathways:

1. Activates the “rest and digest” response

Promotes relaxation, supports healthy digestive activity and encourages balanced heart-rate patterns.

2. Reduces inflammation-related markers

Can help regulate immune signaling pathways associated with discomfort, stress, and overactivity.

3. Decreases oxidative stress markers

Supports cellular resilience and long-term wellness.

4. Enhances neuroplasticity

Encourages adaptive brain changes linked to improved mood regulation, cognitive performance and motor learning.

Is Nervio scientifically validated?

Nervio’s underlying technology is supported by more than 27 scientific studies examining noninvasive vagus nerve stimulation and its effects on the nervous system. Nervio is built using a clinically aligned CES architecture, third-party tested, and engineered to meet high standards for devices delivering controlled electrical impulses to the ear.

While Nervio itself is a wellness device, the neuromodulation pathway it leverages has been researched by leading scientific and academic institutions worldwide.

Why choose Nervio?

Nervio is one of the most comprehensively studied vagus-nerve–targeting wearable systems available without a prescription. It delivers precise, consistent and comfortable stimulation designed for daily use, helping you support mental clarity, stress balance, sleep quality and overall autonomic wellness.

Who is Nervio for

Nervio is designed for adults who want to support their nervous system, improve daily wellbeing and enhance mental and physical performance through noninvasive neuromodulation.

Who should not use Nervio?

Nervio is not suitable for:

- Users who have had surgery to cut the vagus nerve (cervical vagotomy)

- Users diagnosed with very low resting heart rate

- Users with permanently implanted metallic or electronic devices located close to the ear where Nervio is applied

- Pregnant women

Contraindications requiring special assistance

In the situations below, Nervio should only be used if a qualified health professional approves its use and supervises it. If any of these apply to you, your clinician can advise whether Nervio is appropriate in your specific case:

- Users with any active implanted devices (electronic or wearable), including cochlear implants, cerebral shunts, invasive vagus nerve stimulators, or pacemakers

- Users with metal implants that could interact with electrical stimulation

- Users with known significant coronary disease or a recent heart attack

- Children or minors

- Pregnancy has not been evaluated in scientific studies

What do studies say about safety?

Children and individuals with pacemakers have been included in scientific studies of auricular neuromodulation technology. In those controlled research settings, no device-related adverse events or electrical interference were observed. However, these findings do not replace personal medical advice, and users in these categories should always consult a health professional before using Nervio.

How To Use Nervio

  1. Attach the soft pads to the ear clips and moisten them lightly with saline.
  2. Place the clips only on your earlobes for correct vagus nerve stimulation.
  3. Long-press the power button to turn on the device.
  4. Choose your preferred mode and adjust intensity (9 levels).
  5. Set your session duration (15, 20, 30, or 45 minutes).
  6. Relax. The device will automatically shut off when the session ends.

Use daily for best results, especially 20 minutes before sleep.

Unlock Deep Calm That You Haven't Experienced in Ages

For many people, stress never fully switches off. The nervous system remains in a heightened state, keeping the body alert even when it’s time to rest.

Nervio works by gently supporting the body’s natural regulatory systems. Through subtle electrical stimulation, it encourages a shift away from stress-driven activity and toward a calmer, more balanced state.

Users often describe a noticeable quieting of mental noise, a release of physical tension, and a deeper sense of ease that feels natural rather than forced.

Over time, this calmer baseline can support better sleep, improved emotional resilience, and a greater ability to handle daily stress.

How Nervio Works

1

Step 1

Connect the ear clip cable to the Nervio device and attach the soft pads onto each electrode.

2

Step 2

Lightly moisten the pads with saline to ensure proper conductivity.

3

Step 3

Place the ear clips on the earlobes. Both clips work on either left or right ear.

4

Step 4

Short press the mode button and adjust the intensity. Use the timer button to set your session duration.

Great value for a vagus nerve stimulation device

I like how Nervio has contacts for both sides of the neck. I’ve been using it for several weeks and have already improved my sleep quality. My Oura ring confirms the positive changes. I’ve tried skipping a night and my sleep data showed it. Worth it. I like how Nervio has contacts for both sides of the neck.

Safe, effective. good

Due to the nature of my work, I often get stressed. 5 days a week, at least 10 hours each day. I’ve tried different ways and methods to relieve stress but none worked—until I got Nervio. Just a few minutes a day and my stress level dips. A bit pricey but absolutely worth every single use. Due to the nature of my work, I often get stressed. 5 days a week, at least 10 hours each day.

I had insomnia most of my life, but only after one Nervio session, I’ve been able to get a whole night sleep without waking up in the middle of the night.

Great value for a vagus nerve stimulation device

I like how Nervio has contacts for both sides of the neck. I’ve been using it for several weeks and have already improved my sleep quality. My Oura ring confirms the positive changes. I’ve tried skipping a night and my sleep data showed it. Worth it. I like how Nervio has contacts for both sides of the neck.

Safe, effective. good

Due to the nature of my work, I often get stressed. 5 days a week, at least 10 hours each day. I’ve tried different ways and methods to relieve stress but none worked—until I got Nervio. Just a few minutes a day and my stress level dips. A bit pricey but absolutely worth every single use. Due to the nature of my work, I often get stressed. 5 days a week, at least 10 hours each day.

Better mood, sleep overall

Skeptical but hopeful, I started using Nervio nightly. The first time I used it, I felt an immediate sense of calm, something I hadn’t experienced in a long time. After a few days, I noticed I was sleeping better, my mood improved, and I felt more in control of my stress. So worth it. Skeptical but hopeful, I started using Nervio nightly.

A Tool I Actually Recommend to Patients

As a clinician with 30 years of experience, I’m careful with what I recommend. But Nervio genuinely does what it claims. My HRV improved, my stress baseline dropped, and my sleep is deeper. Surprisingly effective for such a simple device. As a clinician with 30 years of experience, I’m careful with what I recommend. But Nervio genuinely does what it claims.

“Nervio is one of the most thoughtfully designed CES devices I’ve seen.”

"With over 30 years of clinical experience in neurology, I’ve seen many patients benefit from non drug approaches to stress and sleep. CES is one of the most researched methods, and Nervio delivers it in a precise and gentle way."

"It provides stable stimulation to pathways involved in calm and emotional regulation, making it a valuable tool for daily nervous system support."

— Dr. Daniel C. Hartwell, Neurologist

Questions? We Have Answers

Is the stimulation painful?

No. The sensation is extremely mild. Most users feel only a soft tapping or warm tingling on the earlobe. You can adjust the intensity across 9 levels for comfort.

Can I use Nervio every day?

Absolutely. Daily use is recommended for optimal results. Most people use it 20 minutes before sleep, while others enjoy multiple sessions for stress relief and focus.

How soon will I feel the results?

Many users feel calmer within minutes. Sleep improvements typically appear within 3–7 days, while deeper benefits (reduced anxiety, better mood regulation) build over 2–4 weeks of consistent use.

Who should not use Nervio?

Do not use if you:

• have a pacemaker or implanted electrical device
• are pregnant
• have epilepsy
• have open wounds on the earlobes

When in doubt, consult your doctor.

Can I move around while using Nervio?

Yes. You can read, work, meditate, or relax. For sleep sessions, most people remain still on a couch or bed.

Can I use Nervio while on medication?

CES is generally safe with most medications, but if you're taking strong psychiatric drugs or stimulants, consult your healthcare provider.

How long does the battery last?

With daily 30-minute sessions, a full charge typically lasts 10–14 days.

How many modes does Nervio have?

Three modes:

  1. Comfort Mode
  2. Stimulation Mode
  3. Enhanced Mode

Each mode has three levels, and you can fine-tune intensity separately.
