Stress Reduction: Experience significant relief from daily stress by activating your vagus nerve and shifting your body into a "rest and digest" state.
Improved Sleep: Pulsetto supports restful sleep by calming your nervous system, helping you wake up refreshed and energized.
Using Pulsetto is simple and takes just 4 minutes to start feeling the effects. Here's how it works:
Apply a generous amount of gel to your neck or directly onto the electrodes.
Place the device on your neck.
Pair it with the Pulsetto app on your smartphone.
Choose your desired program and start the device through the app.
The device creates a gentle, pleasant vibration or tingling sensation in your neck area. This stimulation helps activate your parasympathetic nervous system, leading to a calmer, less stressed state.
A TENS unit (Transcutaneous Electrical Nerve Stimulation) is a small device that delivers low-voltage electrical impulses through the skin to stimulate nerves. It is traditionally used for pain relief, muscle tension, and rehabilitation.
2. Can a TENS unit stimulate the vagus nerve?
A TENS unit can stimulate branches of the vagus nerve when applied correctly. However, unlike medical-grade VNS devices used in hospitals, a standard TENS unit is not specifically designed for vagus nerve therapy. Still, certain settings and electrode placements can produce mild, non-invasive vagal activation.
3. How does TENS-based vagus nerve stimulation work?
The TENS device sends gentle electrical pulses to areas where the vagus nerve has accessible branches, most commonly the ear (auricular branch) or the side of the neck. These signals can help modulate the autonomic nervous system, increasing parasympathetic activity (the “rest and digest” state).
4. What are the potential benefits of vagus nerve stimulation with a TENS unit?
People use TENS-based VNS for:
Improving mood
Enhancing sleep quality
Supporting digestion
Supporting relaxation and calmness
These benefits vary from person to person and depend on proper technique.
5. Where should electrodes be placed for vagus nerve stimulation?
The two most common areas:
Auricular Vagus Branch (Ear)
Concha
Cymba conchae
Tragus These regions contain vagus nerve fibers accessible through the skin.
Side of the Neck (Cervical Region)
Near the carotid sinus
Must be used cautiously to avoid overstimulation
Important: Never place pads directly over the throat or carotid artery without proper training.
6. What TENS settings work best for vagus nerve stimulation?
While there is no universal protocol, many research studies use:
Low intensity: Just enough to feel a gentle tingling
Pulse width: 200–300 µs (microseconds)
Duration: 10–20 minutes per session
The goal is gentle stimulation, not muscle contraction.
7. Is it safe to use a TENS unit for vagus nerve stimulation?
TENS-based VNS is generally considered low-risk when used properly. However, avoid use if you have:
A pacemaker or implanted electrical device
Epilepsy (unless supervised)
Heart rhythm disorders
Open skin wounds
Pregnancy (especially on the abdomen or neck)
Always start with the lowest intensity and increase gradually.
Lower stress hormones
Improve emotional regulation
Promote relaxation
Many people feel calmer within a few minutes of gentle ear stimulation.
9. How often should I use a TENS unit for VNS?
Common routines include:
Daily sessions of 10–20 minutes
2–3 times per day during periods of high stress
Long-term use for maintaining higher vagal tone
Consistency is more important than intensity.
10. Can TENS-based VNS improve sleep?
Many users report better sleep because vagus nerve stimulation can:
Reduce stress before bedtime
Improve nervous system balance
Evening sessions (1–2 hours before sleep) are common.
Stress resilience
Recovery
Parasympathetic activation
Cardiovascular balance
12. Are there side effects?
Possible mild effects:
Tingling
Redness under the pads
Mild dizziness if intensity is too high
Temporary headache (rare)
These usually disappear quickly.
14. Can I use a TENS unit while working or relaxing?
Yes. Many people use low-intensity ear stimulation while:
Working
Reading
Meditating
Watching TV
Just keep intensity low enough to avoid distraction.
15. Is TENS-based VNS the same as medical VNS?
No. Clinical VNS requires implanted or specialized devices used under medical supervision. TENS-based VNS is a non-invasive, milder version, suitable for wellness but not a replacement for medical treatment.
