The Vagus Nerve - Could this be the key to reducing your inflammation?
Summary
This episode investigates the hype surrounding vagus nerve stimulation, featuring neurosurgeon Kevin Tracey who explains how the nerve modulates inflammation and immune response. While FDA-approved implants show promise for treating rheumatoid arthritis and epilepsy, the hosts critique the lack of evidence for popular non-invasive devices and DIY social media hacks. Tracey argues that most consumer gadgets do not specifically target the vagus nerve, suggesting that general healthy lifestyle habits are currently the best way to support this complex neural pathway.
