Introduction
Your nervous system is your body’s master communication highway, designed to adapt, protect, and respond. But what happens when life sends it too many signals, too fast, or for too long? The nervous system begins to store stress in layers. These layers, built over time, affect everything from posture and digestion to emotional regulation and immune health.
Understanding how your nervous system processes and stores stress – whether emotional, physical, or chemical – can be a powerful step toward healing and regulation.
What Does “Layers of Stress” Mean? Imagine your nervous system like a layered cake. Each layer represents a different experience your body has had to process: birth, illness, trauma, toxins, grief, or even a difficult school year. If a stressor isn’t fully resolved or integrated, the body doesn’t forget it – it adapts around it. These adaptations are often protective at the time, but when left unaddressed, they compound.
Research in neurobiology, particularly the work of Dr. Stephen Porges (Polyvagal Theory), shows that the autonomic nervous system (ANS) doesn’t simply flip between “on” and “off”. Instead, it shifts dynamically among sympathetic, parasympathetic, and dorsal vagal states depending on how safe or threatened we feel. Chronic threat perception — even subtle, ongoing stress — results in altered autonomic tone, and this tone gets “recorded” in the body through changes in posture, muscle tone, motor function, and emotional reactivity.
In parallel, the motor system — which includes motor neurons, spinal pathways, and the cerebellum — integrates these stress signals by altering movement patterns, tone regulation, and proprioception. When stress becomes chronic, motor output becomes less refined and more reactive, reinforcing survival postures and limiting mobility.
Over time, this leads to compensatory patterns in:
- Posture and movement (tense shoulders, clumsy gait, poor balance)
- Emotions (overreacting, shutting down, chronic worry)
- Health (digestive issues, sleep problems, chronic inflammation)
The Three Types of Stress That Create These Layers
1) Emotional Stress
- Unresolved trauma, grief, fear, or anxiety
- Stored in the limbic system and influences both autonomic balance and motor output
- Can show up as irritability, fatigue, panic attacks, or depression
- According to trauma researcher Bessel van der Kolk, “the body keeps the score” — meaning our physiology holds the imprint of emotional experience long after the mind has moved on
2) Physical Stress
- Birth trauma, injuries, poor posture, or repetitive strain
- Alters muscle tone, joint function, and spinal alignment
- Creates tension patterns the brain then “normalizes”
- Research in motor control and neuromechanics shows that movement patterns become encoded in the brain and spinal cord, often persisting even after the physical injury has resolved
3) Chemical Stress
- Toxins, poor diet, medications, or environmental pollutants
- Impacts cellular communication and inflames brain and body tissues
- Triggers nervous system inflammation and oxidative stress
- Chronic inflammation affects autonomic regulation and can impair neuromuscular function, leading to chronic fatigue or muscular imbalances
All of these stressors communicate with the nervous system through the same gateways: the autonomic nervous system, the motor system, and the sensory system. That means no matter where the stress starts, it affects the whole body through feedback loops and interdependent systems.
Why These Layers Matter
Each new stressor builds on the old. A child who experienced early emotional disconnection may later develop motor or behavioral challenges. An adult under chronic work stress may begin experiencing digestive problems or autoimmune flares. It’s not random; it’s layered.
Functional MRI studies show that unresolved stress alters default-mode network activity in the brain, particularly in the prefrontal cortex, cerebellum, and limbic structures. These changes affect autonomic control and motor coordination simultaneously. The more layers of unresolved stress, the harder it becomes for the nervous system to shift out of survival and into regulation.
If we don’t address these stress patterns, the nervous system loses flexibility and adaptability — the very qualities it needs to promote healing, movement freedom, and emotional resilience.
The Good News: Your Nervous System Can Change
Thanks to neuroplasticity, your nervous system is always capable of growth and rewiring. But it needs the right input:
- Safe, consistent environments
- Movement and touch-based therapies (like chiropractic care)
- Breathwork and emotional regulation tools
- Nutritional and chemical support
Emerging research in somatic therapy and nervous system healing shows that patterned, predictable input — especially when paired with co-regulation (safe, attuned relationships) — helps rewire trauma responses. The autonomic and motor systems can relearn how to shift into balance, ease, and coordination. This allows stored stress to be released in stages, gently peeling back the layers.
As we remove interference and provide nourishing input, the body can begin to peel back those layers of stored stress and return to its natural state of regulation, healing, and adaptability.
