The body needs homeostasis i.e. equilibrium and a key method by which it it regulates this is through your Vagus nerve.
The Vagus nerve oversees amongst other things your mood, immune function, digestion and heart rate. It literally “wanders” around your vital organs, carrying messages between them.
Vagal tone tells us how the Vagus nerve is functioning at any given moment. Increased Vagal tone has been linked to reduced inflammation and better outcomes for those with chronic illness, anxiety or depression.
Vagal tone is measured in the changes in heart rate that occur with the breath as it involves a slight increase in heart rate on the inhalation and a decrease of heart rate when you exhale.
Historically Vagal tone was assessed by measuring heart rate variability, but that only gives part of the picture. What the BREATHE FLOW test does is to uniquely analyse the synchronization of your heart rate and breathing to accurately assess Vagal tone.
