Benefits of Auricular Vagus Nerve Stimulation (aVNS)
🧠 Anxiety, Depression & Stress
-
Reduces anxiety: aVNS can calm the sympathetic nervous system and increase parasympathetic tone, reducing physiological symptoms of anxiety.
-
Improves depression symptoms: It may modulate neurotransmitters like serotonin and norepinephrine, with effects similar to implanted VNS devices.
-
Enhances stress resilience: By balancing the autonomic nervous system, it improves heart rate variability (HRV), a key marker of stress regulation.
-
May help PTSD: aVNS has shown promise in dampening hyperarousal and intrusive symptoms in trauma-related conditions.
-
Improves sleep quality by promoting deeper, more restorative sleep through calming the nervous system.
🦠 Autoimmune Diseases
- Regulates inflammation by downregulating pro-inflammatory cytokines, such as TNF-alpha, IL-1β, and IL-6, and alleviates symptoms in chronic inflammatory conditions.
- aVNS can decrease inflammation, lessening pain and fatigue symptoms in Lupus patients.
- aVNS has been shown to reduce the activity of inflammatory cells in the gut and suppress damaging inflammation caused by Crohn’s disease.
- And, preventing the recurrence of Crohn’s disease can be achieved with aVNS.
🩺 Pain and Chronic Conditions
- Reduces chronic pain: aVNS influences pain perception and processing in the brain and spinal cord.
- Helps with migraines and cluster headaches: By modulating trigeminal and brainstem pain circuits.
- Supports tinnitus relief: Especially in protocols combining vagal stimulation with auditory retraining.
🧬 Metabolic and Digestive Benefits
- Improves digestion: By enhancing vagal tone, it stimulates gastric motility and secretion, benefiting conditions like IBS and gastroparesis.
- Stimulates gastric motility and secretion, and has anti-inflammatory properties, potentially benefiting conditions like Irritable Bowel Syndrome (IBS) and gastroparesis.
- May aid in weight regulation: Via appetite regulation and reduced stress eating.
❤️ Cardiovascular Benefits
-
Lowers heart rate and blood pressure: Through parasympathetic activation, aVNS can reduce cardiovascular strain.
-
Improves heart rate variability (HRV): High HRV is linked to better stress regulation, cardiovascular health, and longevity.
-
May reduce inflammation in heart conditions: aVNS can modulate systemic inflammation via the cholinergic anti-inflammatory pathway.
-
May improve motor function, reduce muscle weakness, and enhance overall neurological recovery in stroke patients.
