What Is the Vagus Nerve?
The vagus nerve, or cranial nerve X (that’s 10 in Roman numerals), is the longest of the 12 cranial nerves in your body. Its name comes from the Latin word for “wandering,” and boy, does it wander! Stretching from your brainstem to your colon, it’s like an information superhighway connecting your brain to your heart, lungs, gut, and more. It’s a key player in the parasympathetic nervous system, which handles your “rest and digest” functions—the opposite of the “fight or flight” mode.
Here’s what the vagus nerve does:
-
Regulates heart rate and blood pressure: Keeps your ticker steady.
-
Controls digestion: Helps move food through your gut and signals hunger or fullness.
-
Manages breathing: Influences your respiratory rate.
-
Reduces inflammation: Acts like a brake on your immune system to prevent overreactions.
-
Affects mood: Communicates with brain areas tied to emotions, like the amygdala.
What Is Vagus Nerve Stimulation?
Vagus nerve stimulation (VNS) is a therapy that uses gentle electrical pulses to activate the vagus nerve, influencing brain activity to treat various conditions. Think of it as a nudge to your nervous system, helping it function better. VNS comes in two flavors:
-
Implantable VNS: A device, like a pacemaker, is surgically placed in the chest and connected to the left vagus nerve (the right one is skipped to avoid heart issues). It’s FDA-approved for epilepsy, depression, and stroke recovery.
-
Non-invasive VNS: Handheld or wearable devices stimulate the nerve through the skin, often at the neck or ear. These are approved for migraines and cluster headaches and are gaining popularity for stress relief.
Non-invasive vagus nerve stimulation is gaining traction as a natural, at-home solution for a wide range of conditions. Whether you're dealing with anxiety, migraines, or chronic pain, non-invasive devices like Pulsetto offer practical relief by gently activating the vagus nerve.
Studies suggest benefits extend to gut health, brain fog, stress, and even weight loss. Learn more about the benefits of non-invasive vagus nerve stimulation, explore its role in addiction recovery, or discover how music-based vagus nerve exercises can support better sleep and emotional balance.
How Does VNS Work?
VNS sends electrical signals to the vagus nerve, which relays them to the brainstem and beyond, tweaking brain activity. For example:
-
In epilepsy, it calms irregular brain signals that trigger seizures.
-
In depression, it boosts neurotransmitters like serotonin and dopamine.
-
In stress, it enhances heart rate variability (HRV), a marker of resilience.
Implantable devices deliver pulses in cycles (e.g., 30 seconds on, 5 minutes off) and can be activated with a magnet if a seizure or mood dip is coming. Non-invasive devices, like Pulsetto’s, are used for short sessions, stimulating nerve branches in the neck or ear. It’s like giving your nervous system a warm hug!

Natural Ways to Stimulate the Vagus Nerve
The vagus nerve plays a key role in regulating your body’s relaxation response, heart rate, and stress levels. Stimulating it naturally can promote calm and balance without relying on devices. Below are five effective, science-backed methods to activate your vagus nerve and enhance your well-being.
1. Deep Breathing for Vagal Tone
Slow, intentional breathing is one of the simplest ways to engage your vagus nerve. Diaphragmatic (belly) breathing at a pace of about six breaths per minute—inhaling for 4 seconds and exhaling for 6—activates the parasympathetic nervous system. This lowers heart rate and signals your body to relax. Try practicing for 5–10 minutes daily, focusing on expanding your belly rather than your chest.
Quick Tip: Use a guided breathing app or count silently to maintain rhythm.
2. Meditation to Soothe the Mind
Mindfulness meditation, particularly practices like loving-kindness or body scans, can enhance vagal activity by reducing stress hormones. Studies show regular meditation increases heart rate variability (HRV), a marker of vagal tone. Even 10 minutes a day of sitting quietly, focusing on your breath or a positive mantra, can make a difference.
Quick Tip: Start with short sessions using apps like Headspace or Calm if you’re new to meditation.
3. Cold Exposure for a Quick Reset
Exposing your body to cold stimulates the vagus nerve by triggering the “dive reflex,” which slows heart rate and promotes calm. Try splashing your face with cold water for 15–30 seconds or ending your shower with a 30-second cold blast. This not only boosts vagal activity but also sharpens mental clarity.
Quick Tip: Keep a bowl of cold water handy for a quick face dunk during stressful moments.
4. Singing, Humming, or Chanting
Vocal activities like singing, humming, or chanting create vibrations in the throat that directly stimulate vagal nerve branches. These actions also encourage deep breathing, amplifying the calming effect. Whether it’s belting out your favorite song, humming a tune, or chanting “Om” during yoga, the rhythmic vibrations work wonders.
Quick Tip: Hum for 5 minutes while doing chores to sneak in vagus nerve stimulation.
5. Exercise to Boost Endurance and Calm
Moderate aerobic exercise, such as jogging, cycling, or swimming, strengthens vagal tone over time. Endurance activities increase HRV and improve the body’s ability to shift into a restful state. Aim for 20–30 minutes of movement most days, keeping intensity at a level where you can still hold a conversation.
Quick Tip: Pair exercise with nature—like a park run—for an extra mood boost.
FAQ :
What’s the history of VNS?
VNS isn’t new—it’s been around since the 1980s. Researchers first tested it in animals to control seizures, and by 1988, human trials began. The FDA approved the first implantable VNS device for epilepsy in 1997, kicking off its rise as a therapy for other conditions. Today, over 150,000 devices have been implanted worldwide, per a 2024 report from the Journal of Neurology.
How does VNS differ from other neuromodulation therapies?
Unlike deep brain stimulation (DBS), which targets specific brain regions, or transcranial magnetic stimulation (TMS), which uses magnetic fields, VNS stimulates the vagus nerve to influence brain activity indirectly. It’s less invasive than DBS (no brain surgery) and more targeted than TMS, making it versatile for conditions like epilepsy and depression.
Is VNS considered experimental?
Not for FDA-approved uses like epilepsy (1997), depression (2005), stroke recovery (2021), and headaches (2017/2018). However, for conditions like rheumatoid arthritis or PTSD, it’s still in clinical trials, so it’s considered investigational. Always check with your doctor for the latest approvals.
Who’s a good candidate for VNS?
You might be eligible if you:
-
Have refractory epilepsy (seizures not controlled by meds) and are 4+ years old.
-
Have treatment-resistant depression and have tried 4+ therapies without success.
-
They are recovering from an ischemic stroke and need help with arm/hand function.
-
Suffer from cluster headaches or migraines and want a non-invasive option.
-
Are interested in non-invasive VNS for stress or sleep, like Pulsetto’s device.
Can children use VNS?
Yes, for epilepsy, VNS is FDA-approved for kids aged 4 and up. Non-invasive VNS for stress or anxiety isn’t age-restricted but should be used under parental supervision. Consult a pediatrician first.
Are there conditions that disqualify someone from VNS?
You might not be eligible if you have:
-
A history of vagotomy (surgical removal of part of the vagus nerve).
-
Active heart rhythm disorders, as VNS, could interfere.
-
Severe sleep apnea, since VNS might worsen it.
-
Certain psychiatric conditions (e.g., active psychosis) could complicate depression treatment.
Can I exercise with a VNS device?
Absolutely! Most activities—running, yoga, swimming—are fine once you’re healed (about 4–6 weeks post-surgery for implantable VNS). Avoid contact sports like rugby that could dislodge the device.
Does VNS interfere with medical devices or tests?
Implantable VNS can affect:
-
MRIs: Special protocols are needed to avoid device damage. Inform your technician.
-
Pacemakers: VNS is usually safe but requires coordination with a cardiologist.
-
Airport security: Metal detectors may pick up the device—carry a medical ID card.
