The yōjō vagus nerve stimulator activates natural pathways to rest, recovery, and resilience.
The device is a battery-powered pulse generator.
It releases mild electrical impulses. These impulses are delivered through an earpiece.
Our earpiece targets two points in the ear.
Gentle electrical pulses travel through the skin to branches of the vagus nerve just below the surface.
The stimulation feels like a slight tingle.
You can control the intensity and change modes depending on what you need.
The impulses move along the nerve to your brainstem.
They reach your hypothalamus and amygdala. Serotonin, norepinephrine, and acetylcholine release into your system.
Your system slides out of tension and into relaxation.
Stress drops, mood lifts, and inflammation calms. Recovery and repair begin.
Benefits
A more active vagus nerve changes everything
As the main arm of your parasympathetic nervous system, your vagus nerve is central to your lasting well-being.

Overwhelmed? Wired but tired? No off switch?
yōjō reduces stress hormone levels and quiets the amygdala, your brain's alarm center. Every impulse retrains your brain's fear response, so everyday stressors stop triggering a full emergency.
Look forward to bedtime again.
yōjō helps your body shift into the relaxed state it needs to fall asleep and stay asleep. Session by session, it turns down the mental noise that keeps you staring at the ceiling.
Stuck on meh?
yōjō triggers the release of serotonin, dopamine, and norepinephrine, the same neurochemical shift targeted by antidepressants. It also quiets the brain regions that drive low mood and anxiety.
nVNS has been FDA-approved for treatment-resistant depression since 2005.
Tired? Drained by noon?
yōjō stops the drain of being on high alert and redirects your body's resources toward restoration, growth, and repair. The energy that was keeping you braced for impact becomes energy you can actually use.
Tired? Sore? Dreading tomorrow?
yōjō activates your body's built-in anti-inflammatory mechanisms and shifts your body toward repair rather than defence. It also deepens sleep, where most recovery actually happens, boosting your bounce back.
No more cancelled plans or ruined days.
yōjō changes how your brain processes pain centrally, raising your tolerance and reducing the emotional weight it carries. It also activates your body's built-in anti-inflammatory response, reducing the immune activity that drives chronic joint and muscle pain. nVNS is FDA-approved for migraines.
Our platform adapts yōjō to your life and nervous system.
No two nervous systems are exactly alike. And nervous systems are always adapting.
What works for you might not work for someone else. And, what worked today might not work tomorrow.
Your nervous system gets what it needs when it needs it, and you reach your well-being goals. No friction.
And then, we watch and learn. And adapt every step of the way based on your response.
Your nervous system's ability to switch between stress and relaxation can be measured.
We use the latest in face scan technology to capture heart rate, heart rate variability, breathing rate, cardiac workload, and blood pressure.
So you can see the immediate impact of vagus nerve stimulation, witness the switch in your nervous system's state, from stressed to calm.
We integrate with popular health trackers for a deeper dive into sleep and heart rate variability.
Sticking to daily vagus nerve stimulation is hard.
Studies show coaching improves lifestyle change success and adherence.
Using one-on-one coaching sessions or a built-in message chat, your well-being coach helps you get the most out of yōjōing.

yōjōers who work closely with their coaches are more consistent and report feeling more confident at managing stress.
Self-care begins with health literacy.
The more you know the more you can change.
Everything from acetylcholine to zinc, from the color of a moth's wing to why you're tired but wired. All checked by our clinical team. No bunk.
Explore different techniques to self-activate your vagus nerve for on-the-go calm, and try them in guided practice.
