The vagus nerve is one of the main communication lines between body and brain. It belongs to
the parasympathetic nervous system, the part that helps us recover, digest, and rest. When this
nerve is underactive, or when stress responses dominate, people may experience problems
ranging from mood changes, anxiety, over activeness and headaches to digestive or inflammatory
conditions.
How neurostimulation works
Direct neurostimulation delivers very gentle electrical impulses to the vagus nerve (you can not
fell it). These impulses can be applied with external, non-invasive stimulators placed on the neck
or the ear. The goal is not to shock the nerve, but to gently “remind” it of its natural rhythm and
bring balance back to the autonomic nervous system.
Advantages compared to other therapies
• Targeted effect: Neurostimulation directly activates the body’s own regulation pathways,
rather than only influencing symptoms from the outside.
• Low side-effect profile: Unlike many medications, vagus stimulation does not affect
liver, kidneys, or digestion in a systemic way.
• Support for stress resilience: By increasing parasympathetic tone, it helps the body
relax, improves sleep, and reduces stress hormone release.
• Synergy with other treatments: It can be combined with medication, psychotherapy,
physiotherapy, or natural approaches.
• Flexible use: Non-invasive devices make it possible to use stimulation easy. We have
best experiences with 4 applications within 2 weeks.
Applications and areas of treatment
Research and clinical use have shown benefits in:
• Neurology: Epilepsy (reducing seizure frequency and intensity), migraines, cluster
headaches.
• Psychiatry: Treatment-resistant depression, anxiety, PTSD.
• Pain medicine: Chronic pain, fibromyalgia, pain amplification syndromes.
• Internal medicine: Inflammatory bowel disease (Crohn’s, colitis), rheumatoid arthritis,
possibly other autoimmune disorders.
• Rehabilitation and fatigue: Support for long-COVID symptoms, chronic fatigue, and
dysautonomia (POTS).
Practical aspects
Typical sessions last about 20–30 minutes. Stimulation feels like a mild tingling or gentle
tapping sensation if at all. During a session, people may notice:
• Deepening of breathing
• Slower heart rate
• A sense of calm or warmth
• Sometimes mild tiredness afterwards (a sign of parasympathetic activation)
Direct vagus nerve stimulation offers a modern way to gently balance the nervous system. By
addressing the root of many stress-related and inflammatory processes, it can help in areas
ranging from mood and pain to headaches and chronic illness. It works fast and builds up
resilience and a better balanced autonomous nervous system.
