Frequently Asked Questions

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.

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.

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

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.

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.

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.

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

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

No, tVNS does not have to be painful. You are in control of the stimulation level and should set it to a comfortable level.

Most people describe the sensation as like a tingling or prickle sensation. It is usually more noticable at the start of the session and then fades away.

Yes, there is some early data showing that tVNS can reduce the severity of tinnitus.
