What is HRV Relative Balance?
Your HRV Relative Balance represents the equilibrium in your Autonomic Nervous System (ANS). We use HRV as a non-invasive way to measure the balance that exists in the activation of the two branches of your ANS.
The ANS has two subsystems: the rest-and-digest system (Parasympathetic Nervous System) and the activation system (Sympathetic Nervous System). These two systems simultaneously send signals to your heart to keep your nervous system balanced. We describe this as the Relative Balance that exists within your ANS. These systems can be equally active, or one can take over and dominate the other. This constant back-and-forth inside of our bodies causes fluctuations in our heart rate, known as our HRV.
