Sensory overload happens when a child’s nervous system becomes overwhelmed by sensory input from their environment. While adults can experience this too, it most often affects children.

When sensory input becomes “too much,” children may struggle to cope, leading to frustration, anxiety, tantrums, and emotional meltdowns. These reactions are not behavioral choices—they are signs that the nervous system is overloaded.

Common triggers include:

  • Loud or unexpected noises
  • Crowded or busy environments
  • Strong emotions or stressful situations
  • Sudden changes in routine or surroundings
  • Unexpected physical touch
  • Strong or unpleasant smells

What are the Symptoms of Sensory Overload?

Sensory overload can look different for every child, but common signs include:

  • Discomfort or a strong desire to escape a situation
  • Crying, tantrums, or emotional meltdowns
  • Anxiety or heightened fear responses
  • Irritability or agitation
  • Difficulty focusing or following directions

Many children will also cover their ears or eyes, avoid touch, or shut down in loud or busy environments.

Over time, unresolved sensory overload can interfere with development. When a child’s brain is constantly working to manage overwhelming input, it can miss important opportunities for learning motor skills, speech, emotional regulation, and coordination.

Causes of Sensory Overload

Sensory overload occurs when the brain has difficulty organizing and filtering sensory information from the body and environment.

It is often the most visible symptom of Sensory Processing Disorder (SPD), and it commonly appears alongside conditions such as Autism, ADHD, and anxiety.

To understand the root cause, it helps to know the nervous system’s primary roles:

  1. Receive information from inside and outside the body
  2. Filter and organize that information
  3. Create appropriate responses throughout the body

As Dr. Bruce Lipton explains:

“The function of the nervous system is to perceive the environment and coordinate the behavior of all cells in the body.”

When a child has sensory overload, the nervous system lets in too much information that should normally be filtered out, overwhelming the brain.

The Role of Subluxation and Dysautonomia

Two important concepts help explain sensory overload: subluxation and dysautonomia.

Subluxation refers to tension and dysfunction within the nervous system that interferes with how sensory information is processed. When this happens, the nervous system often becomes stuck in a heightened “fight-or-flight” state.

This imbalance—called dysautonomia—means the calming, regulating side of the nervous system (the parasympathetic system) is underactive. As a result, children struggle to self-regulate, calm down, and adapt to sensory input.

The vagus nerve, which plays a key role in calming the body, is especially important here. Birth stress or trauma—particularly with interventions like C-sections, forceps, or vacuum delivery—can affect vagal function and is commonly seen in children with sensory challenges.

How to Cope with and Manage Sensory Overload

Traditional approaches often focus on avoiding triggers. While helpful short-term, this does not address the underlying nervous system imbalance.

Our approach focuses on restoring balance by:

  • Supporting regulation of the Autonomic Nervous System
  • Reducing chronic fight-or-flight stress
  • Activating the calming parasympathetic system and vagus nerve
  • Using Neurologically-Focused Pediatric Chiropractic Care
  • Taking a detailed history of pregnancy, birth, and early stressors
  • Utilizing advanced INSiGHT Scans to guide care

This drug-free approach is designed to help children tolerate sensory input more easily—without constant avoidance.

Sensory Overload Test

One of the most helpful tools for children with sensory overload is the NeuroSpinal EMG Scan, which measures stress and tension in the nervous system.

When excessive stress signals (called nociception) overwhelm the brain, we often refer to this as a “noisy brain.” Instead of calming, organizing input, the brain receives too much disruptive information.

On the other hand, proprioception—input from movement and body awareness—helps organize and calm the brain. Healthy nervous system function allows proprioceptive input to balance out stress signals.

When subluxation interferes with this balance, sensory overload increases. EMG scans help us identify where this imbalance exists so care can be precisely tailored.
