Vagus Nerve Stimulation Techniques for Calmness:

The Cranial Nerve(CN X)/Vagus Nerve

Hello Everybody!

This post is going to be a bit controversial. We are looking at Vagus Nerve Stimulators. Both the physical exercises and the basic techniques as well as the OTC wearables. Over-the-counter (OTC) vagus nerve stimulators are highly controversial. (While clinically implanted or prescription-grade devices are FDA-approved for severe epilepsy, depression, and rheumatoid arthritis, no external OTC gadget has FDA approval for any medical indication. [1, 2, 3, 4, 5])

Vagus nerve stimulation (VNS) activates your parasympathetic nervous system ("rest and digest") to reduce stress, lower heart rate, and decrease inflammation. You can trigger this relaxation response quickly using at-home physical exercises or targeted non-invasive wearable devices. [1, 2, 3, 4, 5]

Physical Exercises and Vocal Techniques for Vagus Nerve Stimulation

Physiological Responses to Vagal Stimulation: [1]

• These methods use the anatomical connections of the vagus nerve (such as the vocal cords, throat, and face) to naturally stimulate a calming effect.

• Cold-Water Face Immersion: Splashing ice water on your face or using an ice roller for 30 seconds triggers the mammalian "diving reflex," which immediately slows your heart rate and redirects blood flow.[1, 2, 3]

Vocalization and Throat-Based Techniques: [1, 2]

• Chanting: Chant "Om" on a long, low exhale, focusing on the vibration moving through your chest. The physical vibration in your throat and chest stimulates the vagus nerve.

• Humming, Singing, & Chanting: Because the vagus nerve passes near your vocal cords, deep humming, singing, or chanting "Om" mechanically stimulates it while forcing you to control your breath.

• Aggressive Gargling: Gargling water vigorously for 30 to 60 seconds engages the muscles in the back of your throat, providing direct VNS.

Breathing and Gentle Movement Exercises: [1, 2]

• Long-Exhale Breathing: Breathe in for 4 seconds, hold for 2 seconds, and exhale slowly for 8 sec.Prolonged exhalesdirect neural brake on your "fight or flight" stress response.

• Basic Neck & Eye Stretch: While lying on your back, interlace your fingers behind your head. Without moving your head, look as far to the right as you can until you swallow or naturally sigh, then repeat looking to the left. [1, 2, 3]

Non-Invasive Vagus Nerve Wearables:

If you prefer targeted technological support, non-invasive neuromodulation devices can deliver gentle electrical, ultrasound, or vibrational frequencies. [1, 2, 3](kind of like a TENS machine but for anxiety)

• 

  TRUVAGA PLUS

  Truvaga Plus: A handheld device that applies gentle, non-invasive electrical stimulation to the vagus nerve on the side of your neck. [1, 2, 3]

• 

  PULSETTO

  Pulsetto: A wearable neckband that uses controlled electrical impulses to stimulate the vagus nerve, helping to manage anxiety and promote sleep. [1, 2, 3]

• 

  APOLLO NEURO

  
  Apollo Neuro: A wearable device worn on the wrist or ankle that delivers gentle, low-frequency vibrations to signal safety to your brain and help your body relax. [1, 2]

• 

  NUROSYM

  Nurosym: A wearable neuromodulation device that clips to your ear (transcutaneous auricular VNS) to stimulate vagus nerve fibers and induce a state of calm. [1]
• 
  

• 

  VAGUSTIM

  Vagustim: An earpiece-style device connected to a mobile app that gently stimulates the vagus nerve through the ear for daily relaxation and stress regulation. [1]

Consumer Experiences with OTC Vagus Nerve Stimulator:Over-the-counter, non-invasive vagus nerve stimulators (e.g., Pulsetto, Apollo Neuro, Truvaga) are widely discussed on health and coaching forums, with consumer feedback leaning toward mixed opinions. [1, 2, 3, 4]

Positive User Testimonials and Reported Benefits: Users reporting success often cite immediate relaxation, better sleep, and reduced anxiety, with some noting long-term improvements in chronic issues. [1, 2]

• "The chatter in my mind just turned off..." – New York Post review of Pulsetto.

• "Day 2 I felt a major difference. This helped me relax and calm down..." – Customer review of Apollo Neuro.

• "...eight months in, the Pulsetto has undeniably given me so much of my life back." – User testimony via Sacramento Bee. [1, 2, 3]

Criticisms and Negative Feedback on Device Performance and Value: Other users cite high prices, cheap build quality, and a lack of noticeable benefits. [1]

• "Def not worth $350.00... Very cheap feeling and does not hold a charge long." – Customer feedback on Apollo Neuro.

• "It's total garbage… I feel a little uncomfortable tingling on my neck but none of the advertised benefits…. " – User in a Reddit Vagus Nerve Discussion. [1, 2]

🪙🪙Here's my two cents:

Honestly, I'm finding this pretty funny. I think (and Google agrees) that this (certain physical exercises and techniques) is similar to what throat singers do. I mean, it's about stimulating the vagus nerve with vibrations.

I've never tried those non-invasive gadgets, so I can't really say much about them. But the mixed reviews are a bit of a red flag. If it's super expensive, I personally wouldn't buy it without a doctor's go-ahead.

Insurance doesn't really cover non-invasive (transcutaneous) vagus nerve stimulators. Major providers, like Medicare, Aetna, Anthem, and UHC, call these devices "experimental" or "investigational," so patients usually pay out-of-pocket since out-of-network benefits might not apply to stuff that's not covered. That's a shame because there is always room to grow and stretch our wings. 

Well, here is where we part ways. I hope this was at the least a little bit enlightening for you. I know I learned something. May your week be filled with constant bouts of forgiveness and gratitude(towards yourself!!). I will talk to you, when I talk to you!
