Have you ever wondered why your child covers their ears, avoids certain clothing, constantly moves, or becomes overwhelmed in busy environments?
These behaviors may be related to sensory processing-the way the brain receives, organizes, and responds to information from the body and environment.
While we often think about five senses, we actually have eight sensory systems that help us navigate everyday life.
Visual – Sight
Helps us process light, movement, colors, and visual information.
You may notice: sensitivity to bright lights, distraction in busy environments, or an interest in watching things move.
Auditory – Hearing
Helps us process sounds and voices.
You may notice: covering ears, distress with loud noises, or frequently making sounds.
Tactile – Touch
Helps us process textures, temperature, pressure, and physical contact.
You may notice: avoiding certain clothing or messy textures, or frequently touching and handling objects.
Olfactory – Smell
Helps us detect and process odors. You may notice: strong reactions to perfumes, cleaning products, or the smell of certain foods.
Gustatory – Taste
Helps us process flavors and plays an important role in eating.
You may notice: strong food preferences, avoiding unfamiliar flavors, or seeking intense flavors.
Vestibular – Movement & Balance
Helps us understand movement, balance, and our relationship to gravity.
You may notice: constantly running, jumping, or spinning-or avoiding swings, heights, or certain movement activities.
Proprioception – Body Awareness
Helps us understand where our body is and how much force we are using.
You may notice: crashing, pushing, climbing, chewing, bumping into things, or seeking deep pressure.
Interoception – Inside the Body
Helps us notice internal signals such as hunger, thirst, fatigue, temperature, pain, and changes associated with emotions. You may notice: difficulty recognizing hunger or thirst, forgetting to use the bathroom, or struggling to identify what they are feeling.
What Is Sensory Overload?
Sometimes the brain receives more sensory information than a child can comfortably process. This can lead to sensory overload.
A child may:
Cover their ears
Become upset or irritable
Cry or have a meltdown
Run away or shut down
Seek movement or pressure
Need to be alone
These behaviors are often a form of communication. Instead of only asking, “Why are they behaving this way?”, we can ask:
“What might their nervous system be experiencing right now?”
Every Child Is Different
Sensory needs can vary from child to child-and even from day to day. A child may seek movement but avoid loud sounds, or tolerate certain sensations at home but become overwhelmed at school.
Understanding these differences can help us respond with curiosity instead of judgment.
Occupational therapy can help identify sensory patterns and explore individualized strategies that support participation in everyday activities such as dressing, eating, sleeping, school, play, and social interactions.
Sometimes, understanding what a child’s body is communicating is the first step toward helping them feel more comfortable and successful in their everyday world.
