When individuals turn to medical devices, they should search for quality products with a strong basis of evidence. This ensures the safety of all users and helps produce the best results. Individuals should do the same when looking for vagus nerve stimulation devices, which activate the vagus nerve to address a variety of mental and physical health concerns.

To make this process easier, we’ve extensively researched vagus nerve stimulation devices. This article is a compilation of our findings based on statistics, reviews, and other data. You can use this information to choose the device that works best for your needs.

Who Can Benefit From VNS Devices?

Vagus nerve stimulation devices can benefit individuals with a range of health concerns. These devices can be wearable or implanted in the brain. Vagus nerve stimulation devices offer gentle vibrations that target the vagus nerve through the skin. Some devices are worn on the neck while others are worn on the earlobe, ankle, or wrist. Implanted vagus nerve stimulation devices, on the other hand, are surgically placed in the chest. These devices provide stimulation through the vagus nerve in the neck.

It’s important to note that all of the research studies we discuss here pertain to wearable vagus nerve stimulation devices, with the exception of those used to manage epilepsy.

Anxiety & Panic Disorder

Research shows these devices offer short-term and long-term symptom improvement for those with treatment-resistant anxiety disorders (specifically obsessive-compulsive disorder and panic disorder). [1] Studies done with these populations have been small, meaning more research is needed to definitively prove the effectiveness of these devices for anxiety disorders. However, early results are promising.

One study discussed the potential benefits of pairing vagus nerve stimulation devices with exposure-based therapies to manage anxiety and fear in people who have Autism Spectrum Disorder (ASD). [2] While not much research has been done to determine how effective this combination is, vagus nerve stimulation devices can maximize the benefits of many other therapies.

PTSD & Trauma Recovery

Vagus nerve stimulation devices have been known to benefit other mental health concerns, including trauma-related conditions. Research shows that vagus nerve stimulation devices are associated with a clinically meaningful improvement in post-traumatic stress disorder (PTSD) symptoms and severity. These results were measured immediately after use as well as 6 months later. [3] This demonstrates that vagus nerve stimulation devices can be safe, realistic, and effective in treating this particular condition.

Another study found that vagus nerve stimulation devices minimized stress-induced cellular changes in those with PTSD when paired with another treatment called personalized traumatic scripts. [4]

Depression

Vagus nerve stimulation devices have been approved by the Food & Drug Administration (FDA) for the treatment of severe, recurrent depression. Therefore, this is one of the most studied uses of vagus nerve stimulation devices. Studies have shown individuals who received vagus nerve stimulation demonstrated slight improvements in depressive symptoms compared to individuals who received sham or no treatment. [5]

A 5-year study looked at the benefits of vagus nerve stimulation devices for people with chronic moderate to severe depression compared to treatment as usual. Participants who received vagus nerve stimulation experienced a higher treatment response rate compared to the other group (over 67% compared to 40.9%). In addition, those who received vagus nerve stimulation saw a 43.3% remission rate while the other treatment yielded a rate of 25.7%. [6] These study results are considered quite impactful due to the large scale, long-term nature of the research.

Migraines & Headaches

Research shows that over 50% of individuals who received non-invasive cervical vagus nerve stimulation experienced a decrease in the intensity and severity of their migraines. These results showed vagus nerve stimulation devices are a safe way to manage migraines and other headaches. [7] Another study found these devices can help lower pain intensity and severity as soon as 30 minutes before a migraine and up to 60 minutes after onset. [8]

Epilepsy

Epilepsy is another often-studied condition as it applies to vagus nerve stimulation devices. As mentioned earlier, vagus nerve stimulation devices used for epilepsy are implanted in the chest. Research indicates around half of individuals with drug-resistant epilepsy experienced 50% fewer seizures. [9] It is important to note that this method has more potential side effects than wearable vagus nerve stimulation devices, including vocal cord paralysis and infection.

Long COVID & Dysautonomia

Experts have found that some individuals with long COVID develop vagus nerve dysfunction, which can be managed using these devices. One study found that dysautonomia symptoms improved while the device was running, but symptoms returned after the treatment was complete. [10] However, benefits may be seen on a cellular level, even when the device is used for short periods of time. Other research found that vagus nerve stimulation devices may have anti-inflammatory effects and can even balance immune system function. [11] More research and setting changes may be needed to determine the potential for long-term effects with nervous system conditions.

Burnout, Stress, and Sensory Overload

Dated research over the years has shown near-immediate improvements in sensory processing after the use of vagus nerve stimulation devices. Sensory processing skills can help individuals balance sensory overload and cope with cognitive stress. In addition, newer studies have discovered that vagus nerve stimulation devices may have more lasting changes on the brain that allow for long-term improvements in managing sensory input. [12] There is less research on the connection between vagus nerve stimulation devices and the management of burnout. However, this is another potential application due to the connection between sensory processing skills and cognitive stress.

A Sensory-Based Alternative: Soundsory

SoundSory is another treatment option for individuals interested in stimulating their nervous system to manage trauma, anxiety, and sensory sensitivities. SoundSory utilizes rhythm and movement along with sound-based (auditory) and vestibular input to support the nervous system. Auditory input allows individuals to develop stronger pathways in the brain that assist with communication and learning. [17] [18] Vestibular input, which assists with creating coordinated movements, is also known to strengthen the vagus nerve. This type of input often helps people move more smoothly and experience fewer concerns related to nausea and motion sickness. [19]

The effects of this sensory information are magnified even further when paired with vagus nerve stimulation. Therefore, individuals can benefit from SoundSory on its own or alongside a vagus nerve stimulation device. It’s important to note that SoundSory is not an electrical stimulator, so it does not work in the same way the above devices do. However, it has demonstrated benefits to the nervous system.

How Do VNS Devices Work?

Vagus Nerve Stimulation (VNS) devices work by sending gentle electrical pulses to the vagus nerve, which is crucial for regulating important body functions like heart rate, digestion, and stress responses.

Regardless of the brand and type of vagus nerve stimulation device, these machines all work in the same way by sending gentle electrical impulses to the vagus nerve. These impulses are meant to activate the nerve, balancing many of the body’s functions and easing health concerns stemming from vagus nerve dysfunction.

VNS Device Types

Vagus nerve stimulation devices are available in various forms. Some devices are neck collars, which involve placing small pads called electrodes on the skin of the neck. Since the vagus nerve travels from the brain down through the body, it runs down both sides of the neck. Therefore, neck collars offer surface-level access to the main nerve branches. Some people prefer earbuds that offer vagus nerve stimulation, as these are discreet and worn just as traditional earbuds are. When in place, these devices stimulate a section of the vagus nerve called the auricular branch, which is located in the outer ear.

Ear clips operate in a similar fashion, though they are designed more like ear hooks (also known as over-the-ear earbuds). They also involve stimulating the auricular branch through the ear canal.

Lastly, wearable bands are placed on the wrist just like watches or bracelets. This is a popular style as the device remains easily visible to the user. Electrical impulses are sent from the wrist up through the arm and to the vagus nerve.

VNS Device Mechanisms

Regardless of what device you use, impulses from these machines travel from the vagus nerve to the brain stem and the cerebrum. The brain stem is located at the base of the skull and is responsible for vital functions such as heart rate and breathing rate. The brain stem also controls involuntary reflexes such as pupil dilation, swallowing, gagging, coughing, and sneezing. If the body continually receives electrical impulses, this strengthens the vagus nerve.

A stronger vagus nerve leads to higher heart rate variability, which means the body can better manage varied intervals of time between heartbeats. This builds resilience and leads to improved cardiovascular health.

The vagus nerve also communicates with the cerebrum, which is the main part of the brain divided into four lobes. These lobes control a wide array of functions. However, impulses coming from the vagus nerve help regulate cerebrum functions such as emotion regulation, pain recognition, mood, digestion, and more.

By strengthening the vagus nerve, the cerebrum builds a stronger bond with the digestive system through what is called the gut-brain axis. This axis is not just a network of nerves – it also contains pathways responsible for hormone and immune system communication. Strengthening this axis allows the vagus nerve to improve digestion. Healthier digestion, in turn, leads to a better balance of hormones and mood. This creates a chain reaction that encourages improved health across several bodily systems and functions.

Are VNS Devices Safe?

Yes! Many people tolerate vagus nerve stimulation devices quite well. There are very few side effects associated with wearable/non-invasive vagus nerve stimulation devices. Side effects that may occur include throat tightness and discomfort, dizziness, tingling, voice hoarseness, headache, and coughing. These side effects are most likely to occur with wearable devices that target the neck, but may still occur with other devices. [20]

Certain individuals are advised to consult with their doctor before using these devices. These include pregnant women, those with heart conditions, people who have epilepsy, and pacemaker users. The electrical impulses emitted by these devices may interfere with the above conditions. Your doctor will determine whether or not it is safe to use a vagus nerve stimulation device.

How to Use a VNS Device at Home

If you are beginning to use your vagus nerve stimulation device at home, there are some things you should keep in mind:

Start low and go slow: This refers to the device’s settings. Starting low means you should set the intensity as low as possible when starting out. You can adjust it based on your comfort level as you get more used to the device. It’s also important to go slow, so start with short intervals of time and gradually increase.
Daily use is most effective: As with any treatment, consistency is key to seeing positive results. If you only turn to your device once in a while or during times of particularly high stress, you are unlikely to see lasting results. By using your device on a daily basis, you can monitor bodily changes and strengthen your vagus nerve.
Track HRV, sleep, mood: This step helps you see progress along the way and can encourage consistent device use. Your product should offer specific insights into heart rate variability, sleep duration, amount of deep sleep, and more, either through a paired app or the device itself. Some people prefer to track these markers with their device, while others may want to record them in a journal.
Combine with breathwork or cold therapy: You can combine the vagus nerve stimulation device with other stimulation techniques such as deep breathing, cold therapy, exercise, and more. Try several methods and choose what works best for you.

Final Thoughts: Should You Try a Vagus Nerve Device?

Vagus nerve stimulation devices are excellent tools for individuals wanting to better manage chronic stress, sleep difficulties, anxiety, and dysregulation. Remember to use your device as instructed to ensure your safety. Daily use is the best way to see the results you want.

Many individuals find even more positive outcomes when combining these devices with other vagus nerve stimulation methods such as SoundSory, breathing exercises, and cold exposure. Some individuals may also want to seek psychotherapy (also known as talk therapy or mental health counseling) to manage difficult emotions and learn more strategies to build a positive mood. No matter what combination of methods you use, a strong commitment to improving the health of your vagus nerve with evidence-based treatments will yield the best results.
