How to Fix Your Nervous System: HRV, Stress & Healing with That HRV Guy (Salim Najjar)

takeaways

1. Salim Najjar shares how he shifted his HRV baseline from around 32 to over 150 by moving beyond biohacking metrics into sleep, emotional processing and nervous system work.

2. The conversation explains HRV as the variance between heartbeats, reflecting the autonomic nervous system's ability to move between sympathetic (fight or flight) and parasympathetic (rest and digest) states, and argues there is no universal 'good' score — only your personal 30-day baseline.

3. Salim frames chronic stress as the leading cause of cellular inflammation, explaining how the body sends oxygenated blood to the extremities during perceived threats even when there is no real danger.

4. He describes emotions as scalar waves meant to move through the body in about 90 seconds, and unprocessed emotions from the formative years (ages 2–7) as 'frozen glaciers' stored in the fascia.

5. The episode walks through his five pathways for HRV growth: sleep as the foundation, hormetic stress as the catalyst, reframing the shift, intentionality and alignment, and community as the amplifier.

6. Salim recounts his personal story of losing his father at 7, building and eventually losing a sparkling tea company, filing for bankruptcy, and reframing a bike-accident shoulder injury as happening 'for' him.
