Episode 84: How Vagus Nerve Stimulation Improves Sleep, Anxiety, and Recovery


ree


🧬 Episode Overview


In this powerful episode, Jenny Jones (BiohackerBlondie) sits down with Povilas Gudziunas, co-founder of Pulsetto, to explore how vagus nerve stimulation, stress modulation, and nervous system tracking can reshape health from the inside out.

Povilas breaks down how chronic stress disrupts immune function, sleep, emotional regulation, digestive health, and mitochondrial energy—and why most people never learn to properly regulate their nervous system. Pulsetto offers an evidence-based, non-pharmaceutical intervention that bridges neuroscience and everyday wellbeing through electrical stimulation of the vagus nerve paired with guided breathwork protocols.


🔬 1. Why Nervous System Regulation Is the Foundation of Health


  • Chronic stress keeps the body in sympathetic (”fight-or-flight”) mode, impairing cellular repair, memory, metabolism, and sleep.

  • Dysregulated nervous system = hormonal imbalance, inflammation, high cortisol, anxiety, shallow breathing.

  • The vagus nerve is the primary pathway that shifts the body into parasympathetic repair mode.


Transcript Reference:“We built Pulsetto because people focus on treatments, supplements, hacks… but unless the nervous system shifts out of stress mode, nothing works properly.”


⚡ 2. How Pulsetto Works


Pulsetto uses non-invasive vagus nerve stimulation paired with personalized guided sessions in the app to:

  • Reduce cortisol + improve stress resilience

  • Increase HRV

  • Improve sleep quality

  • Enhance recovery after emotional or physical stress

  • Support the immune response through improved autonomic balance

It stimulates the auricular branch of the vagus nerve via electrical frequency—no needles, no implants.


Key Insight:VNS is clinically researched in PTSD, anxiety, IBS, heart rate variability, and inflammatory pathways.


🧠 3. The Science Behind Vagus Nerve Stimulation


  • Boosts parasympathetic activity

  • Improves communication between brain + organs

  • Enhances emotional regulation through limbic pathways

  • Reduces systemic inflammatory markers


Transcript Reference:“When the vagus nerve activates, the body finally gets the signal: ‘We’re safe. We can recover now.’”


😴 4. Using Pulsetto for Better Sleep & Recovery


  • Sessions help shift the body from wired-but-tired → calm + ready for rest

  • Helps break cycles of nighttime rumination

  • Supports deeper stages of sleep needed for cellular repair

Protocol Mentioned:

  • 10 minute session before bed

  • Pair stimulation with diaphragmatic breathing

  • Use “Deep Sleep” or “Evening Wind-Down” mode


🫁 5. Stress, Breathwork & Emotional Healing

Pulsetto pairs tech with breathwork and emotional regulation—giving users structured, evidence-based tools to retrain stress responses.


Examples from the episode:

  • Tools for calming panic

  • Using stimulation before high-stress events

  • Supporting trauma release alongside therapy

  • Using HRV as a metric of healing


📱 6. Why Tracking Matters

Data inside the app can reflect progress over time:

  • Heart rate variability (HRV)

  • Sleep patterns

  • Recovery response

  • Stress cycles


“Without awareness, people don’t know they’re living in chronic stress because it becomes their baseline."


🌍 7. The Future of Nervous System Tech


Pulsetto is developing:

  • AI-personalized VNS protocols

  • Integration with wearables for closed-loop adjustments

  • Programs for immune health, menstruation cycle support, and mental resilience

This shifts wellness from reaction → regulation + prevention.


✨ Key Takeaways


✔ Nervous system regulation is the foundation of health

✔ You can shift from fight-or-flight to parasympathetic using VNS

✔ Stress affects hormones, metabolism, immunity, and sleep

✔ Breathwork + tech = faster emotional and physical recovery

✔ Healing is easier when your body feels safe
