We Tested Vagus Nerve Stimulation Devices for Stress Relief

After learning more about the vagus nerve, I was surprised that this topic is not brought up more often. After all, while more studies are definitely needed, emerging research on non-invasive vagus nerve stimulation devices shows that they may potentially aid stress management, help improve sleep quality, and possibly support relaxation.

But many people are not even aware that these non-invasive devices are available for home use. That’s why I decided to explore this topic further by testing out several available models myself.

In this article, I guide you through the best vagus nerve stimulation devices currently available, having tested a wide range of them myself. I combined my hands-on experience with academic research to present both my personal impressions and the potential benefits of vagus nerve stimulation.

Top 5 vagus nerve stimulation devices – my shortlist

1. Nuropod – best overall
2. Pulsetto – cost-effective option
3. Hoolest – handheld option
4. SONA– personalized VNS device
5. ZenoWell – budget-friendly earpiece vagus stimulation device

What experts say about vagus nerve stimulation devices

Scientists acknowledge the therapeutic potential of vagus nerve stimulation (VNS) and transcutaneous vagus nerve stimulation (tVNS) devices for various bodily function support.

Emerging research on tVNS has explored whether it could help with headaches, sleep issues, and certain mental struggles. While currently available studies consider it generally safe and convenient for most, tVNS is yet to be endorsed by the medical community and more research on its potential risks and benefits is needed.

Best vagus nerve stimulation devices in 2026 – detailed list

After testing numerous vagus nerve stimulators, I’ve picked 5 options that are worth considering in 2026. This list is based on criteria such as features, simplicity of use, pricing, warranty, and real-life customer reviews. Read further to find the most suitable device for you.

1. Nuropod – overall best non-invasive VNS device

Starting price:	$810.00–900.00 (depending on the region)
Warranty/guarantee:	2-year warranty for the device, 6-month for the earpiece, 30-day money return
Amazon rating:	not available
Trustpilot rating:	4.3 ⭐⭐⭐⭐
Certified medical device:	Yes
Certification mark:	FDA NSR Designation, CE

Check out Nuropod

Out of all devices I tested, Nuropod struck a balance between everyday usability and comfort during longer sessions, making this product my personal favorite.

The technology that powers Nuropod, known as Auricular Vagal Neuromodulation Therapy™ (AVNT™), uses gentle electrical impulses claimed to modulate the vagus nerve through the outer ear. According to the brand, this may help support self-repair and recovery mechanisms. In other words, Nuropod promises to potentially enhance natural physiological responses that maintain balance and overall well-being.

Ease of use

Getting started with Nuropod was simple. Inside the box, you get the main controller unit, the earpiece with its electrode clip, and a charging cable – nothing overwhelming.

The device clips into the tragus, and I will jump ahead to say this was not ideal for me. Since my tragus is relatively small, I had to readjust Nuropod quite frequently. I gave the device to one of my coworkers, and he didn’t experience this issue, so this does not seem to be a universal flaw in design.

The sensation created by Nuropod can be described as tingly. I would say it is unusual but not uncomfortable, but I wouldn’t call it pleasant either, although I got used to it after a few sessions.

When it comes to mobility, I couldn’t wear it during walks or similar daily activities, but you don’t have to be completely still. I was able to use it while working on my computer and reading, but I had to be cautious not to fidget.

This device does not require gels, unlike similar VNS devices such as Pulsetto, making the process mess-free with no cleanup needed afterward.

Scientific research

Research on transcutaneous auricular vagus nerve stimulation (taVNS) – the broader technique underlying Nuropod – is an active and growing field.

Parasym claims involvement in 50+ scientific studies and collaborations with institutions including Harvard, Bart's Health NHS Trust, UCLA, and the University of Chicago Medical School. However, many of these studies examine taVNS as a general technique rather than Parasym's specific device, and "collaboration" can range from formal partnerships to independent research at those institutions. At the moment of this publication, none of them are openly accessible, so we can't really verify any of it.

The broader taVNS literature has suggested preliminary evidence of potential benefits, including modulation of heart rate variability and reduction of inflammation markers. Researchers have also hypothesized that taVNS may be associated with possible improvements in anxiety, sleep, and mood.

Pricing

Nuropod has a premium tier price tag, ranging from $810.00 to $900.00, depending on the region. The device comes with an earpiece, a charger, a starter guide, and a carrying case. Nuropod also guarantees a 30-day money-back return and a 2-year warranty, in case of an issue.

Various financing options are also available, including VAT relief for the UK market and HSA/FSA eligibility for the US market. Furthermore, taking part in a remote research study provides an additional discount and, later on, a rebate.

User reviews

What I found is that Nuropod users often share positive feedback on platforms like Trustpilot, where it currently holds a 4.3 out of 5 rating based on 1000+ reviews, and YouTube. The reviews consistently mention benefits such as feeling calmer, sleeping better, and finding it easy to use daily at home. Many say it’s portable and handy, while some report feeling more focused and relaxed within weeks of starting. One of the most common complaints aligns with my experience: the clip doesn’t hold on the tragus that well, especially if you have a small one.

Who is it for?

Nuropod may be appropriate as an adjunct tool for people who feel drained, run-down, or out of balance and are searching for something that supports daily recovery and long-term wellness. It may be a good choice for those looking for additional support for managing fatigue or recovering from long periods of stress. If that’s you, ask your healthcare provider if taVNS could be worth considering.

Nuropod, however, might not be the most suitable choice for people with a small tragus, though remaining still should be sufficient to avoid unclipping.

2. Pulsetto – the most budget-friendly tVNS device

Starting price:	$278.00
Warranty/guarantee:	2-year warranty, 30-day money return
Amazon rating:	4.2 ⭐⭐⭐⭐
Trustpilot rating:	4.2 ⭐⭐⭐⭐
Certified medical device:	No
Certification mark:	FCC

Check out Pulsetto

Pulsetto is an affordable device designed for transcutaneous vagus nerve stimulation. It delivers electrical pulses through two electrodes, one on each side of the neck, aiming to activate both sides of the vagus nerve. In other words, it attempts to offer broader stimulation compared to other popular VNS devices.

When on full battery, Pulsetto can operate for several days and is rechargeable using a USB-C connection.

Ease of use

Setting up Pulsetto for the first time was fairly simple, though it took me a few minutes to get familiar with the placement and stimulation settings. Pairing the device with the app was quick.

The Pulsetto app plays a big role in the overall experience. During testing, I liked being able to switch between different programs and adjust the stimulation intensity depending on how strong or gentle I wanted the session to feel. I also found that Pulsetto’s app integration provides a more interactive experience compared to Nuropod’s hardware-focused design, with many breathing exercises, affirmations, and guided meditations available.

The app also allows you to track your usage and monitor progress over time, as well as use a sound library.

However, the app would sometimes crash, meaning I was not able to use the device until the issue was solved. This is why Nuropod was easier to integrate into my routine: it is operated via the manual controller, not an app.

Overall, Pulsetto offers a user-friendly design with comfortable electrodes and intuitive controls. But if you want to move around while stimulating the vagus nerve, Pulsetto might not be suitable, as it requires you to stay quite still.

Pulsetto comes in two versions at the moment: Lite (the original) and FIT. What’s the difference? Pulsetto FIT is an upgraded version of the Pulsetto Lite, offering several improvements. While FIT is designed to suit a wider range of people, particularly smaller or more sensitive users, it is more compact and offers a more enjoyable experience for all. It provides enhanced app features not available in the older versions, including 5 specialized programs to help with stress and mild anxiety. Additionally, FIT comes with an upgraded battery, meaning the device should last up to 20% longer than the older version.

Scientific research

Most of the claims regarding potential Pulsetto benefits come from scientific studies on vagus nerve stimulation in general, although Pulsetto itself has been used in clinical trials as well.

For instance, a small 2025 peer-reviewed study using Pulsetto proposed that the device may increase alpha brain-wave activity, which is associated with a calmer mental state, while also helping influence arterial blood pressure compared to sham stimulation. Another early pilot study using Pulsetto suggested that it may provide migraine support by helping lessen the intensity and frequency of the attacks.

However, while these findings are intriguing, more research is needed to better understand the potential long-term risks and benefits, especially since the above cited studies are of small size.

Pricing

Pulsetto is the budget option on this list. Pulsetto Lite is FCC-certified and costs $278.00; the newer FIT version costs $296.00. Both come with a 2-year warranty and a 30-day money-back guarantee, so you can try these devices risk-free.

Compared to Nuropod ($810.00–900.00) and SONA ($951.00), Pulsetto costs roughly a quarter to a third of the premium-tier devices. It's slightly more expensive than Hoolest ($179.10) but offers a more polished app experience.

For an additional $10, you can get access to daily educational emails. Claim the Pulsetto discount code and save!

User reviews

Pulsetto has garnered mixed but generally positive feedback online. With a 4.2 out of 5 rating on Trustpilot based on over 3,000 reviews, this makes it the most-reviewed device on this list. The most consistent positive trends are users reporting reduced stress and improved sleep, along with appreciation for the app's guided sessions and the compact design.

While some find vagus nerve stimulation calming and effective after consistent use, others remain skeptical about its long-term impact, and understandably so as its long-term effects are still unknown. The device pairs easily with an app for personalized sessions, but requires proper setup for best results, since you need to remain still during the session.

Who is it for?

Pulsetto might be suitable for people looking for additional support who feel tense during the day, have trouble sleeping, or want help staying calm in everyday situations. If you’re struggling with this, consult your healthcare provider first.

Since it is controlled via an app, it might not be suitable for those who don’t use smartphones. However, if you enjoy guided breathing exercises, meditations, and app-based routines, Pulsetto’s app might actually be an advantage for you.

3. Hoolest – compact handheld vagus nerve stimulator

Starting price:	$179.10
Warranty/guarantee:	1-year warranty, 60-day money return
Amazon rating:	not available
Trustpilot rating:	2.8 ⭐⭐⭐
Certified medical device:	No
Certification mark:	No certifications

Check out Hoolest

Hoolest is a compact, handheld device designed for targeted stimulation of the vagus nerve. It is intended to potentially provide quick relief during stressful situations.

The product features a single electrode that can be placed on the neck, shoulders, arms, or legs. Regardless, although the brand suggests shoulders, arms, or legs as potential placement sites, for me, it was unclear how the signal would reach the vagus nerve, as it doesn’t travel anywhere near these sites.

Hoolest lasts multiple sessions on a single charge, making it ideal for use on the go.

Ease of use

When I got to test Hoolest, I was excited about its premise to provide quick relief. Its compact design allowed me to take it with me everywhere I went, but I have to admit that using it wasn't as easy as I expected. Since there are no universal placement guidelines for this product, I had to figure out for myself what feels best, so it took some time to get it right. One thing I appreciated about Hoolest, compared to other devices I’ve tried, is that it uses gel tips, meaning you do not need to clean up after usage.

I also liked that I could choose from five stimulation modes and adjust the intensity levels. The controls felt intuitive and easy to use, although there’s no app or phone connectivity.

Hoolest recommends using the device for at least 5 minutes to help calm an anxious mind. As per the brand, using it twice per day may help to increase resilience. Due to the suggested short session time, Hoolest was easy to incorporate into my routine.

Scientific research

On the official website, Hoolest states that VeRelief has been tested on over 150 participants through multiple placebo-controlled studies. These trials aimed to check its effectiveness in reducing stress and promoting relaxation using vagus nerve stimulation. However, the results of these clinical trials have not been published in any peer-reviewed journals, making validation impossible.

Just like other VNS brands, Hoolest mostly relies on the results of broader vagus nerve stimulation research rather than device-specific, independently verified studies. This highlights a need for further peer-reviewed research to solidify its efficacy.

Pricing

Hoolest claims to have conducted 3 IRB-approved and placebo-controlled studies across hundreds of people. You can get it for $179.10 with a 60-day money return and a 1-year warranty.

User reviews

User feedback on the VeRelief Prime by Hoolest is a bit of a mixed bag. On the positive side, many people have noticed a reduction in stress and tension, and they really appreciate how easy it is to use and take with them anywhere. It’s great for those looking for a quick way to unwind on the go. On the flip side, the most common negative trends are skepticism about long-term effectiveness, discomfort with the gel requirement, and inconsistent results depending on electrode placement. To learn more, check out our in-depth Hoolest review.

Who is it for?

Hoolest VeRelief is built for people who experience sudden anxiety, panic, or feel easily overwhelmed in stressful environments. It could potentially be useful as a supporting method for those who need quick relief in moments of high stress. If you’re struggling with anxiety, stress, or any other mental health problems, consult your healthcare provider first.

Since you have to “find” the correct placement yourself, it may not be ideal for users who prefer a fully guided, no-assembly-required experience or who feel uncomfortable with devices that require some initial adjustment. Moreover, as mentioned by the brand, it may not be suitable for those with some conditions or experiencing certain symptoms, including postural tachycardia syndrome (POTS), long COVID, and brain fog.

4. SONA – best device delivering personalized stimulation

Starting price:	$951.00
Warranty/guarantee:	1-year warranty, 30-day money return
Amazon rating:	not available
Trustpilot rating:	N/A
Certified medical device:	No
Certification mark:	CE, UFCC, and RoHS

Check out Sona

The SONA device is a vagus nerve stimulator that also reads your biometrics to deliver truly personalized stimulation. To achieve that, it tracks heart rate variability (HRV) and uses AI algorithms, making adjustments in real time based on whether the data shows you may be overactivated or underactivated.

Ease of use

Since SONA delivers personalized nerve stimulation, users don’t have to worry about choosing the best settings. Moreover, the earpiece is also easy to put on, with no confusing manuals on how to use the product needed.

Scientific research

As per the brand’s website, SONA actively collaborates on research, from daily stress to Parkinson's and tinnitus. However, just like other VNS brands, SONA mostly relies on the results of broader vagus nerve stimulation research to support its claims rather than publicly accessible, device-specific, independently verified evidence.

The company's AI-powered personalization and real-time physiological tracking are marketed as key differentiators, yet the clinical evidence supporting these specific features remains limited to internal data, making it impossible to verify to us.

Pricing

At a price of $951.00, the SONA device is a significant investment. However, it distinguishes itself as the only option claiming to provide a personalized experience on this list. No additional costs will be required after the initial cost, as the product includes lifetime access to the app and no gels need to be repurchased.

For your peace of mind, SONA also offers a 1-year warranty together with a 30-day money-back policy.

User reviews

At the moment, the device has not gathered a significant number of reviews online due to being a relatively new product on the market.

SONA is still in its growing phase, which means consumer trust is something it is actively working to build. While the lack of user reviews might be a downside for those seeking informed opinions from previous buyers, the company’s focus on research helps boost its credibility slightly.

Who is it for?

Best for biohackers and self-optimizers who don't just want stimulation — they want personalized stimulation. Moreover, the SONA app allows progress tracking, making it an enticing option for data-driven users.

SONA is not for users who prefer a "set and forget" device. It may also not be suitable for those who find complex technological ecosystems or high-frequency data collection overwhelming.

5. ZenoWell — budget-friendly earpiece vagus stimulator

Starting price:	$327.20
Warranty/guarantee:	2-year warranty, 30-day money return
Amazon rating:	not available
Trustpilot rating:	4.6 ⭐⭐⭐⭐
Certified medical device:	No
Certification mark:	CE, FCC, and RoHS

Check out ZenoWell

ZenoWell Luna aims to deliver auricular vagus nerve stimulation (taVNS) via a headphone-style form factor in the left ear. You can choose from four modes: Sleep for insomnia, Relax for stress, Medit for mindfulness and meditation, and Relief for headaches.

In general, the device is intended to help its users achieve peace and increase resilience to stress.

Ease of use

Getting started with the ZenoWell Luna was straightforward. The setup is designed to be user-friendly: there is no app or subscription to deal with, you simply connect the earpiece and go.

For me, ZenoWell worked better than Nuropod mobility-wise, as it is inserted into the ear, like an earphone, rather than clipped to the tragus. I found I could move around freely while wearing it, making it easy to incorporate into my daily routine, whether I was resting or working. However, I’ve noticed that some reviewers were unsatisfied with the size of the eartip, claiming it doesn’t stay in or feels uncomfortable in the ear.

Before usage you have to moisten the electrodes with either gel or water. This was a bit inconvenient, as some cleanup is needed after use, but manageable.

Although the sensation was described as pleasant and massage-like on the official website, as with other vagus nerve stimulators, I found it rather peculiar, especially during my first few sessions. It wasn’t painful or uncomfortable, just strange, and I had to use a lower intensity with this device.

Scientific research

The studies ZenoWell references on its science page were conducted using other taVNS equipment under controlled research conditions, not the consumer product it sells. In other words, like many consumer VNS brands, ZenoWell relies on the broader body of taVNS research to support its claims rather than device-specific, peer-reviewed evidence. Without clinical trials testing the ZenoWell device directly and publishing results in independent journals, consumers cannot verify whether the device's particular design and stimulation parameters produce the same therapeutic effects observed in the general literature.

Pricing

ZenoWell Luna is currently priced at $409.00. All ZenoWell vagus stimulation devices come with a 2-year warranty and a 30-day money-back guarantee, allowing you to try them risk-free.

You do not need to have any subscription to use ZenoWell products, but you do need to prime the electrodes with either gel or clean water. If you opt to repurchase gel, it will cost you an additional $59.00 for a three-bottle bundle, lasting for around 5 months.

User reviews

ZenoWell has a 4.3 out of 5 on Trustpilot, but that is based on fewer than 50 reviews at the moment. The most consistent positive trend is users stating it improved sleep and supported anxiety management. Users frequently mention the headphone-style design as comfortable and customer support as helpful and responsive.

As the most common complaint, some people mention issues with fit, raising concerns that the one-size-fits-all might not be universal.

Who is it for?

ZenoWell offers a unique relief mode aiming to help reduce headaches. If you experience this symptom, see a healthcare provider for an adequate diagnosis and ask them whether devices like this could be potentially helpful. It also requires no apps or subscriptions, making it ideal for anyone who just wants to put it on and go without fiddling with a phone.

This device is not ideal for people who want to track their results because it does not have an app. It may also not suit people who want more control over the stimulation settings, since it only offers fixed modes.

How to choose the best vagus nerve stimulation device?

Many tVNS devices on the market claim to give you the best result, so making that choice can be tricky (it can feel like a test of the scientific method itself). During my research, I identified a few factors that can help you distinguish the good from the bad. These are some suggestions to get you started:

• Consult with a healthcare provider. Before considering any tVNS device, consult with a healthcare provider, preferably a neurologist or a specialist familiar with VNS therapy. They can advise you regarding whether tVNS suits your specific condition (like lingering symptoms of COVID), evaluate whether it could be safe and appropriate for you, and explain potential risks and benefits.
• Identify the health concern. While more research is needed, people use tVNS therapy for various health concerns such as stress-related symptoms, anxiety, depression, migraines, and to possibly help boost the immune system. Getting an appropriate diagnosis from a healthcare provider and knowing the condition you're aiming to target can help narrow down your device options, as some might be more suitable for individual needs.
• Type of stimulation. tVNS devices offer non-invasive vagus nerve stimulation through earlobe, or neck electrodes, unlike prescription invasive devices requiring surgery for an implanted device. Note that the tVNS devices aim to stimulate the nerve indirectly in different ways – via the earlobe, neck, or other localized areas.
• Safety and side effects. Understand the safety profile, signs and symptoms, and potential side effects associated with each device. While non-invasive tVNS devices use low-level electricity and are thought to carry only minor risks, discuss them with your doctor as these devices may not be suitable for everyone.
• Cost of the device. The pricing of tVNS devices varies and can range from several hundred dollars to $952.00. Check out different products and consider the overall cost, including device purchase and ongoing maintenance like additional subscription costs, gels, batteries, and so on.

What is the vagus nerve and how do stimulation devices work?

The vagus nerve is one of the body’s most important communication lines.

It runs from the brainstem down through the chest and abdomen, connecting to many organs, including the heart, lungs, and digestive system. It is thought to play major role in regulating many bodily functions, including heart rate, blood pressure, respiration (breathing), immune system responses, and mood.

Vagus nerve stimulation (VNS) involves using a device to send electrical impulses to the vagus nerve.

There are two types of VNS devices. Invasive versions are surgically implanted and approved for treating conditions like epilepsy and treatment-resistant depression. Non-invasive devices, which are more common for everyday use, sit on the skin — usually on the ear or neck — and aim to deliver low-level stimulation through small electrodes. Some even include sound therapy or breathing guidance.

While non-invasive VNS isn’t FDA-approved for medical treatment, early studies explore its potential role in supporting relaxation, better sleep, and focus.

How tVNS works at a neurological level

As of now, the mechanism of non-invasive vagus nerve stimulation is not fully understood, with early studies focusing more on the effects of stimulation on people than on how it produces these effects.

That said, the explanation of how these devices work starts with their potential to reach the vagus nerve through the skin. Unlike surgically implanted stimulators, non-invasive devices aim to deliver electrical pulses from the surface, targeting areas where the vagus nerve or one of its branches runs close to the skin, most notably the ear and neck.

In theory, once the signal reaches the vagus nerve, it may be activated, triggering a chain of reactions. Research has proposed several mechanisms that may be triggered by vagus nerve stimulation, including changes in anti-inflammatory signaling and potential regulation of certain neurotransmitters.

It is worth emphasizing, however, that much of this remains theoretical or supported only by early-stage evidence. Moreover, the exact degree to which non-invasive devices could replicate the effects of surgically implanted stimulators is still debated, and individual responses vary considerably.

How to use a VNS device correctly

If you are considering a non-invasive VNS device, it is crucial to use it correctly, as failing to follow the manufacturer’s instructions and your doctor’s suggestions may increase the likelihood of side effects. For this reason, always read the instructions for your particular device – each uses different technologies, so there are no universal guidelines for using a VNS device.

Start by learning the correct placement of your device. For instance, Nuropod is clipped to the tragus and would not deliver any potential benefits if placed elsewhere. Some stimulators, such as Pulsetto, require gel to be used.

The next step is to make sure you know the recommended session durations and frequencies. While there’s not enough evidence that would allow us to know for how long and how often these devices should be worn to achieve results, some brands say their products are meant to be used daily, even a few times per day, while others, such as Hoolest, claim they may be used during the heightened stress moments.

More does not mean better when it comes to vagus nerve stimulation, and it applies to intensity as well. If you feel dizzy or have a headache, this could be because the device’s currents are too intense for you. If the side effects do not subside even after reducing the intensity, do not continue using it and seek medical advice.

Non-invasive VNS devices are not meant to treat any conditions and should not replace medical treatments. It is best to discuss VNS usage with your healthcare provider beforehand.

What are the potential benefits of vagus nerve stimulation?

While research on vagus nerve stimulation (VNS) is in its infancy, particularly for non-invasive methods like tVNS devices, there might be some potential benefits associated with stimulating this nerve through the skin.

Support emotional well-being

Non-invasive VNS may positively impact mood, with a 2018 meta-analysis suggesting potential reductions in depressive symptoms in people with depression compared to sham stimulation.

Additionally, one small study observed increases in motivation and wanting and more push to put in effort in depression patients following taVNS, although these findings are preliminary. More research is needed, as evidence is limited and studies are often conducted with depression patients.

Beyond depressive symptoms, non-invasive vagus nerve stimulation has been explored for possibly affecting stress physiology.

Support sleep

The vagus nerve helps regulate the body’s relaxation response, supporting the shift toward the calmer physiological state associated with falling asleep. Several studies on transcutaneous tVNS have shown promising results, suggesting improvements in sleep quality scores, shortened sleep latency, and longer periods of deep sleep in individuals with insomnia. However, inconsistencies in stimulation placement, treatment protocols, and study durations across the existing research highlight the need for further standardized studies to establish definitive conclusions about tVNS as a reliable sleep intervention.

Support blood pressure regulation

The vagus nerve plays a role in regulating heart rate and blood pressure. A 2020 article published in the Cold Spring Harbor Perspectives in Medicine explored if VNS therapy could support blood pressure regulation. However, evidence is still emerging, and VNS devices are not intended to treat or cure high blood pressure. It is important to consult a healthcare provider before using VNS for cardiovascular concerns.

Adjunct in headache management

Emerging research suggests that VNS may help reduce the frequency and intensity of certain types of headaches. While more research and clinical trials are needed, emerging studies have already shown promising signs for supporting migraine and cluster headache management.

Keep in mind that more research is needed to fully understand the long-term effects of VNS, especially for non-invasive methods like tVNS devices. Additionally, VNS therapy is not a one-size-fits-all solution. Consult a healthcare professional to determine if VNS is right for you and to discuss potential risks and side effects.

How much do vagus nerve stimulation devices cost?

To help you make an informed decision, I created a comparison table with prices for top vagus nerve stimulation devices (available online). Find standard prices, bundle offers, alternate device types, and subscription or membership fees below:

Device	Standard price	Bundle price	Alternate type price	Subscription or membership fees
Nuropod	$800.00–900.00 (depending on the region)	❌	$100 off if you enroll in the remote study	❌

SONA	$926.00	❌	❌	❌
ZenoWell	$327.20	❌	❌	❌

What are the possible side effects of vagus nerve stimulation?

According to recent studies on the safety of transcutaneous auricular vagus nerve stimulation (taVNS), these devices are generally considered safe and are expected to cause mild side effects only. Nonetheless, like any medical procedure, there may be side effects. The most common ones experienced by users I found include:

• Tingling or prickling sensation in the skin
• Throat pain or discomfort
• Voice changes
• Coughing
• Shortness of breath
• Nausea or upset stomach
• Headache

So, if any of these – or other – unusual reactions occur after undergoing vagus nerve stimulation, I always recommend consulting your doctor regarding further use.

Who should avoid vagus nerve stimulation (VNS)

Generally, according to currently available research, vagus nerve stimulation is considered safe, but it’s not recommended to everyone.

While more research is needed to allow us to know who should not use non-invasive devices, invasive VNS is not recommended for people who have insulin-dependent diabetes mellitus, are pregnant or breastfeeding, or have a history of heart arrhythmias or seizures.

Always talk to a qualified healthcare professional before starting any kind of nerve stimulation therapy.

How else can you support your well-being?

While these devices offer a modern approach, there are other ways you may support your well-being without using any technology.

For instance, slow deep breathing (less than 10 breaths per minute) is a great example of a technique that may have similar effects as vagus nerve stimulation, such as increased of heart rate variability (HRV), a marker associated with parasympathetic (rest-and-digest) nervous system activity.

The diving reflex is known to slow the heart rate in response to submersion in water. Dialectical behavior therapy (DBT), a form of therapy that helps people cope with intense emotions, uses cold water to trigger this reflex as a distress tolerance skill. During a moment of heightened emotion, specialists instruct their patients to submerge their face in cold water and hold their breath for 15–30 seconds.

Holistic practices like yoga and meditation often incorporate techniques such as mindfulness and body awareness that may be beneficial for mental health. These usually require consistency over time.

It is easier to find what works for you by talking with a trained professional, who can guide you through these and similar techniques.
