Why HRV often predicts immune “tolerance” before labs do.

 

Dear Colleagues, Students, and Friends,

 

Today is Mini-Training Day 2 in our FM 2.0 sequence:

 

HRV + Immune

I also included a free Day 2 worksheet to go with today’s training:

“This worksheet is one small piece of the FM 2.0 operating system. Inside FMU, we teach the full sequencing framework across all layers, with case-based training and assessments.”
 

HRV + Immune Readiness Screen + first-step sequencing choices.
 

It’s designed to help you avoid flares and choose the safest next move.  
 

In complex chronic illness, HRV is often one of the most practical clinical signals we have for regulation and readiness—especially when immune flares, reactivity, and poor tolerance keep stalling progress.

 

In this short training you’ll learn:
 

• why HRV reflects autonomic regulation (and why that matters for immune behavior)
• how low HRV often predicts flares, intolerance, and “nonlinear” recovery
• how rising HRV often predicts improved tolerance and better sequencing outcomes
• how this fits the FM 2.0 order: regulation → readiness → repair
