Your heart rate is never meant to be perfectly steady. The "space between the beats" is actually a vital indicator of your Vagus nerve health, your capacity to handle stress, and your recovery from trauma.
Heart Rate (BPM) tells you how many times your heart beats per minute. Heart Rate Variability (HRV) measures the variation in time *between* each of those heartbeats.
A high HRV suggests that your nervous system is balanced and highly responsive to changes in your environment. A low HRV often signals that the body is stuck in a "survival" or sympathetic state—exhausted and unable to switch into "Rest and Digest" mode.
The Vagus nerve is the "Super Highway" of your parasympathetic nervous system. It sends constant signals between your brain and your heart, lungs, and gut. When your Vagus nerve is strong (high "Vagal Tone"), it acts like a brake on your stress response, allowing you to return to calm quickly after a scare.
Because HRV is largely controlled by the Vagus nerve, it is the most reliable way to measure your "bottom-up" regulation capacity. [2]
| State | HRV Pattern | Nervous System Goal |
|---|---|---|
| Sympathetic (Fight/Flight) | Low / Stiff | Survival, urgency, hyper-vigilance. |
| Dorsal Vagal (Shutdown) | Suppressed / Flat | Numbness, dissociation, depression. |
| Ventral Vagal (Safe/Social) | High / Fluid | Connection, repair, emotional clarity. |
Unresolved trauma keeps the nervous system in a "survival loop." Even when there is no immediate threat, the body behaves as if danger is imminent. This chronic sympathetic load "flattens" your HRV, leaving you with very little physiological buffer.
This is why people with trauma often feel "reactive" or easily "triggered." It isn't a lack of willpower; it is a physiological lack of capacity. At Goodsky, we use somatic practices to gently expand this "Window of Tolerance" without re-traumatising the system.
You can "train" your Vagus nerve to improve your HRV over time. Consistency is the key to signaling safety to the brainstem.
You cannot have a resilient nervous system if your cellular health is compromised. Metabolic and functional medicine address the physical barriers to regulation.
Not necessarily. You can have a high heart rate while exercising but still have healthy variability. However, a chronically high resting heart rate combined with low HRV usually indicates systemic fatigue or over-training.
Modern wearables (Oura, Whoop, Apple Watch) track this, but for clinical accuracy, we use specific heart-rate straps or medical-grade actigraphy during assessments at our retreat.
Targeted repletion of Magnesium, Omega-3s, and B-vitamins can support the nervous system, but they work best when paired with lifestyle foundations like sleep and breathwork.
If you feel like your nervous system is "stuck," our multidisciplinary team can help you map the biological and psychological drivers behind your symptoms.
