## What is Resonance HRV?

Resonance breathing is now proven in scientific studies to have positive effect in reducing both stress, anxiety and depression. This is further backed up by regular tracking of heart rate variability (HRV), a very strong indicator of your body physical or mental strain, and how only 10 minutes of daily resonance breathing can significantly improve HRV.

+ HRV Optimization - Resonance also - optionally -  allows you to find you body's Optimal breathing rhythm through advance HRV analysis during test session.

For HRV optimization, connect a regular bluetooth heart rate monitor (HRM) chest strap.
