There is a specific frequency where your heart, lungs, and nervous system synchronize. It’s called Resonance Frequency Breathing (or Coherent Breathing).
The math is simple: breathe in for 5.5s, breathe out for 5.5s.
By hitting ~5.5 breaths per minute, you aren't just "relaxing"—you are actively increasing your Heart Rate Variability (HRV) and shifting from "fight or flight" into physiological coherence.
