What if leader performance, focus, and resilience could be trained—physiologically? In this episode, aerospace engineer–turned–inventor Mark Fox (former Space Shuttle chief engineer) unpacks the science and application of PEMF therapy and vagus nerve stimulation—including real-world outcomes on anxiety, PTSD, sleep, HRV, and focus for both people and pets. We explore why heart rate variability (HRV) is a key resilience metric and how portable tools like Vibe and VegaVibe help leaders regulate on the go—no shocking, buzzing, or freezing required.

What You’ll Learn / Key Points

• PEMF 101: What it is, how it differs from general EMF, and why low-frequency energy can be therapeutic.
• Energy → Biology → Behavior: Charging cell membranes and supporting ATP can translate to less pain, better sleep, calmer focus.
• Vagus Nerve Basics: Why vagal tone matters for decision-making and recovery—and how stimulation can raise HRV.
• The HRV Edge: Mark’s team saw a 35% average HRV increase in one hour in recent testing.
• Protocols that Matter: Brain balancing, anxiety/PTSD, inflammation, and how to think through protocol selection.
• Measure What You Want to Improve: Use wearables to track sleep, HRV, blood sugar, BP; evaluate changes over 30 days.
• Practical Use: Pocket-sized PEMF you can wear while working, traveling, or resting.
