Heart Rate Variability
Heart rate variability is a tool that provides insight into function of the Autonomic Nervous System (ANS).
The ANS is divided into two branches:
Normally we have a balance between the two divisions, allowing us to properly respond to stressors when needed, and going back to the rest and digest state following meals and times of relaxation.
However, it is common in modern society for us to be constantly exposed to stressors, whether psychological (i.e. work, relationships, finances), physical (pain, injuries, poor nutrition), or inflammatory (i.e. dysbiosis, chronic infection).
When we are under constant stress, we become sympathetic dominant - a hyperactive state that does not allow the body to recover and heal. If we are in sympathetic mode, we also have difficulties properly digesting and absorbing our meals, leading to digestive dysfunction (i.e. acid reflux, IBS, constipation) and nutrient deficiencies.

How Does Heart Rate Variability Work?
The two branches of the autonomic nervous system, the sympathetic and parasympathetic branches, control the speeding up and slowing down of our heart rate. By measuring the beat to beat variations of heart rhythm, we can assess the activity of the sympathetic and parasympathetic responses.
The heart rate variability assessment also gives us an indication of our adaptive capabilities and how well we are regulating homeostasis (internal balance).

Benefits of Heart Rate Variability Testing
Aside from giving an overall impression of nervous system health and balance, HRV can also be beneficial for:
- Anxiety
- Depression
- Insomnia
- Fatigue
- Digestive Disorders
- Cardiovascular Disease
- Diabetes
