Understanding your INSiGHT scans
What is HRV — and what does your score actually mean?
When we review your INSiGHT scan together, one of the most meaningful pieces of data we look at is your HRV — Heart Rate Variability. Here's a deeper look at what it measures, why it matters, and how we use it to guide your care at Adapt.
Your heartbeat holds more information than you think
Most people imagine their heartbeat as a perfectly steady drum. But a healthy heart actually shows natural variability between each beat — and that variability is a powerful signal about how well your nervous system is adapting to the demands of your life.
Your heart rate is governed by two branches of your autonomic nervous system working in constant conversation with each other:
Your "fight-or-flight" branch. It activates in response to stress, challenge, and perceived threat — speeding up your heart rate and mobilizing your body for action. Essential for survival, but harmful when it never fully shuts off.
Your "rest and restore" branch. Governed by the vagus nerve, it calms the sympathetic response, resets your metabolism, and gives your body the space to recover, heal, and rebuild. This branch is the key to long-term health and resilience.
The healthier this relationship is, the more variability you'll see between heartbeats — and the higher your HRV. Measuring HRV is essentially a way of checking in on how well your vagus nerve and parasympathetic system are doing their job.
Over time, chronic stressors — poor posture, emotional stress, financial pressure, even vertebral subluxations — keep the sympathetic system stuck in overdrive. The nervous system begins to treat this heightened state as "normal," leaving the parasympathetic system less and less able to restore balance. HRV allows us to measure exactly how this imbalance is showing up in your body.
The Rainbow Graph (Adaptability Reserve Graph)
Your neuroPULSE HRV result is plotted on what we call the Rainbow Graph — or Adaptability Reserve Graph. This graph captures two distinct things at once:
Which nervous system branch is dominant. The ideal is center. Plotting left means sympathetic dominance; plotting right means parasympathetic dominance.
How much overall adaptive energy your autonomic nervous system has. Higher means more reserve — greater capacity to handle stress, recover, and heal.
Your result is a single point on this graph, placing you in one of five zones. Each zone tells a unique story about how your nervous system is currently functioning — and gives us a clear picture of where we're guiding you.
The five zones — where does your dot land?
This is where we want you to be. Your sympathetic and parasympathetic systems are balanced, and your overall adaptive reserve is above average. The higher your dot plots in the green zone, the greater your capacity to handle life's stressors, recover from illness, and truly thrive. This zone is very attainable — and staying here is one of the core goals of your care at Adapt.
High activity, but sympathetically dominant. Your nervous system has reserve, but your parasympathetic branch isn't keeping pace — your body runs at full throttle without enough recovery time. Common in driven, high-performing people and athletes.
Parasympathetically dominant, but not by choice. The sympathetic system has become insufficient — adrenal function is low, and the body is sluggish and unresponsive to everyday demands. People here often feel chronically tired despite rest.
The most common zone for people entering chiropractic care. Sympathetically dominant with low adaptive reserve. Immune response is lowered, inflammation is higher, and the nervous system is struggling to manage everyday stress. Vertebral subluxation is a primary driver here.
Very low parasympathetic responsiveness and minimal adaptive reserve. The body has little capacity to respond to additional stress of any kind — physical, emotional, or environmental. This zone requires dedicated, consistent care to begin moving the needle.
Why we track this over time
HRV isn't just a number — it's a real-time reflection of how your nervous system is holding up. Vertebral subluxations, the very thing neurologically focused chiropractic care addresses, are one of the primary forces keeping your sympathetic system stuck in overdrive and your parasympathetic system from restoring balance.
By tracking your Rainbow Graph across your care journey, we can see your nervous system actually shifting — from distress toward adaptability, from exhaustion toward vitality. That progress isn't just something you feel. It shows up right here in your objective scan data.
