The longest nerve
in your body
Follow the vagus nerve as it connects your brain to nearly every major organ. Understanding this nerve is the first step to feeling vagally better.
The only nerve you
can touch
A small branch of the vagus nerve surfaces at the tragus of your ear, making it the only cranial nerve accessible from outside the body. This is the gateway that vagal stimulation targets.

deeper into the body...
Your heart's
quiet conductor
The vagus nerve slows and steadies your heartbeat. Higher vagal tone means greater heart rate variability, a key marker of cardiovascular health and resilience.
Every breath
you take
The vagus nerve regulates the rhythm of your breathing, managing airway diameter and the smooth muscles that expand and contract your lungs.
The gut-brain
connection
Your gut contains over 500 million neurons. The vagus nerve is the primary highway linking this second brain to your first, and research suggests it plays an important role in digestion, inflammation, and immune function.
The mind-body
connection
The vagus nerve plays a central role in emotional regulation. Research suggests that stimulating it may help reduce anxiety, support mood, and promote a sense of calm. Many users report feeling noticeably better over time.
One nerve.
Every system.
From heart to gut to brain, the vagus nerve connects mind and body through a single remarkable pathway. And the part you can reach? Right here, at the tragus of your ear.
