Questions About Vagus.net tVN Stimulator

Device specific questions

How long should I stimulate for?

We recommend 15 mins per day. This follows some of the latest research that aims for the ideal balance between time commitment and efficacy.

However, many studies have shown that longer periods of stimulation (45 mins) can in some circumstances be more beneficial to some people. If you feel you may benefit from longer daily stimulation, the vagus.net simulator can be used in multiple consecutive sessions.

How do I recharge the stimulator?

Use the included USB charging cable connected to any USB power socket.

You can purchase a replacement charging cable here.

What are the known side-effects of tVNS?

Reported side-effects are minimal and include skin irritation or redness under the electrode.

Can I Wear a Hearing Aid When Using tVNS

You should remove your hearing aid before using tVNS. If you have an implanted hearing device then you should not use tVNS.

What is the "vaseline" for?

It looks a bit like vaseline but it's actually conductive paste. You put a little smudge on the gold electrodes of the clip before clipping the clip to your tragus.

The conductive paste greatly reduces the resistance between your skin and the electrical circuit.

The effect of using paste is to greatly reduce the sensation of the stimulation. In our tests users were able to stimulate at much higher levels without discomfort when using this conductive paste.

What's the difference between vagusnet and a TENS machine

There is actually a big difference. Most tens machines are voltage-controlled, while the vagusnet stimulator is a current-controlled device. We advice against the use of standard TENS machine in the stimulation of the vagus nerve. To learn why, read our blog post "Should you use a tENS Macgine for Vaugs Nerve stimulation" on the subject.

How long should I use tVNS for?

We recommend at least 15 minutes per day but this is just a minimum to see results.

Many studies use longer session durations and you can now increase the session length up to 60 minutes.

Questions about transcutaneous Vagus Nerve Stimulation

How long should I stimulate for?

We recommend 15 mins per day. This follows some of the latest research that aims for the ideal balance between time commitment and efficacy.

However, many studies have shown that longer periods of stimulation (45 mins) can in some circumstances be more beneficial to some people. If you feel you may benefit from longer daily stimulation, the vagus.net simulator can be used in multiple consecutive sessions.

What is the difference between tVNS and VNS?

The "t" stands for transcutaneous meaning through the skin and this is the key difference. VNS devices are implanted inside the body whereas tVNS devices are not, because they operate through the skin.

How does tVNS work?

tVNS works by passing a small electrical current through a part of the ear so that it stimulates the Vagus nerve.

What is Vagus Nerve Stimulation Used For?

Vagus Nerve Stimulation has been used to treat epilepsy and depression. This is done with implanted Vagus Nerve Stimulators. Scientists are now researching non-invasive Vagus Nerve Stimulation using devices that connect to the ear. This is being used to investigate other possible benefits of VNS.

Can tVNS Help with Migraines?

Yes. There is some data that indicates people suffering from headaches, cluster headaches and migraines may see some benefit from the use of tVNS; for example see this scientific study

However, as reported, actual results may be dependent on the individual and may vary.

Where is the Vagus Nerve Stimulated?

The Vagus nerve is named after the greek word meaning "wander". This is because anatomical studies revealed that it travels a wide path throughout the human body. From the stomach, lungs, heart and brain but also to the ears. So the easiest location to stimulate the Vagus Nerve happens to be in the ear.  Specifically the tragus of the left ear.

What are the known side-effects of tVNS?

Reported side-effects are minimal and include skin irritation or redness under the electrode.

Can I Wear a Hearing Aid When Using tVNS

You should remove your hearing aid before using tVNS. If you have an implanted hearing device then you should not use tVNS.
