All about
taVNS.
Transcutaneous auricular vagus nerve stimulation reaches the nervous system non-invasively through the ear, activating parasympathetic pathways to restore biological calm.
By delivering gentle micro-electrical pulses to the auricular branch, BeCozU eases sympathetic tension, helping quiet the mind and prepare your body for restful sleep.
Why taVNS.
Easy to Use
Hook the device around your ear, open the app, and start a 30-minute session.
Gentle & Non-Invasive
A safe, non-pharmacological approach using shallow micro-impulses through the skin, free of invasive procedures.
10 Intensity Levels
You choose the intensity in the app: 10 levels, one step at a time, with a confirmation each time. Start low, and raise it only if you want to.
How it works.
The signal leaves the ear, reaches the brainstem nuclei, and the body releases its own calming neurotransmitters: GABA and serotonin.
1. Auricular Vagus Nerve
The electrode sends impulses through the skin of the ear to the auricular branch of the vagus nerve.
2. Brainstem Nuclei
The signal reaches the brainstem nuclei, easing the excessive sympathetic responses behind tension.
3. GABA & Serotonin
GABA promotes sleep and induces calming effects. Serotonin facilitates sleep and helps reduce anxiety.
GABA: promotes sleep and induces calming effects.
Serotonin: facilitates sleep and helps reduce anxiety.
Safe at the Cellular Level
For most adults, the perception threshold of electrical current is typically below 5 mA. taVNS devices operate within the range of 0.5 to 2 mA, which is considered safe at the cellular level, and the penetration depth into tissue is shallow.
Real-time
biometric monitoring.
While taVNS works through the left ear, a PPG sensor in the right ear keeps track of your heart rate. Both show up in the BeCozU app.
Proven stress management.
In a 4-week clinical study, participants using BeCozU experienced significant, measurable reductions in stress, anxiety, and sleep disturbances.
* PSQI: Pittsburgh Sleep Quality Index | PSQs: Perceived Stress Quotient | DASS: Depression Anxiety and Stress Scale (-a: anxiety; -d: depression; -s: stress).
* Results are based on clinical trial findings vetted by professionals in our field. Results are temporary and may vary by individual.
Backed by research.
Peer-reviewed studies on stress, sleep, and recovery.
…taVNS interventions resulted in reduced stress levels, improved sleep quality, and enhanced perception of stress.
Overall, these findings demonstrate a favorable safety profile of taVNS… supporting its use as a suitable non-invasive tool in both research and clinical applications.
Participants in the repeated session protocol increased their HRV, cognitive performance, and sleep efficiency. In particular, taVNS induced higher parasympathetic activation.
The promising results underscore taVNS as a potential neuromodulatory intervention for anxiety-related conditions.
* While inspired by taVNS technology, BeCozU is a wellness device and not intended to diagnose, treat, cure, or prevent any disease. Effects vary from person to person.
Not a miracle.
