SCIENCE: What if a small, non-invasive device could help regulate your nervous system, reduce inflammation, improve cognitive function, and support recovery from chronic illness?

Dr Elisabetta Burchi, psychiatrist, entrepreneur, and Head of Research at Parasym, is helping advance the growing field of neuromodulation, using gentle electrical stimulation to influence the body's nervous system through the vagus nerve.

Often described as the body's communication superhighway, the vagus nerve plays a key role in regulating heart rate, inflammation, mood, cognition, and overall resilience.

Parasym has developed a transcutaneous vagus nerve stimulation (tVNS) device that stimulates the nerve through the tragus, a point on the outer ear, providing a non-invasive alternative to implanted technologies.

Backed by more than 100 studies and clinical trials, vagus nerve stimulation has been investigated across a wide range of conditions, including Long Covid, ME/CFS, hypertension, depression, fatigue, anxiety and cognitive dysfunction, with promising results.

Parasym has also explored how vagus nerve stimulation may enhance cognitive performance and mental clarity in healthy individuals, raising interesting questions about the future of health and human performance.

In this episode, we explore:

What the vagus nerve is and why it matters
How vagus nerve stimulation works
The science behind neuromodulation
The difference between non-invasive ear stimulation and implanted devices
How stimulation may affect heart rate variability (HRV), inflammation, and neuroplasticity
What the evidence says about effectiveness, safety, and adherence
The potential role of vagus nerve stimulation in both chronic illness and everyday health

Whether you're interested in chronic illness, neuroscience, longevity, or optimising brain and body function, this conversation explores one of the most exciting and rapidly evolving areas of health science.
