Sensory Overload/SEN-sor-ee OH-ver-load/
When sensory input (sound, light, touch, smell, movement) exceeds the brain’s capacity to process it comfortably, leading to distress and reduced functioning.
Andy says:
It’s like all the radio stations blasting at once. Turning some down—or off—helps you think and breathe again.
Detailed Explanation
Overload can be sudden (siren, crowd) or cumulative (open office, fluorescent lights). Signs: irritability, shutdown/meltdown, nausea, pain, dizziness, or difficulty thinking. Prevention and rapid relief are key.
Community Context
Common in autism/ADHD; acceptance of stimming, headphones, sunglasses, and quiet breaks reduces incidents. Clear routes to low‑sensory spaces help everyone.
Quick Tips
- Leave or reduce input quickly; headphones/sunglasses on
- Close eyes, breathe slowly, sip water; move to a quieter spot
- Use scripts to exit and re-enter when ready
Do / Don't
- Do: dim lights, reduce noise, simplify tasks
- Do: provide quiet corners and opt‑out options
- Don't: force stay or conversation; don’t take it personally
Scripts (Examples)
- "I need a sensory break; I’ll be back in 10 minutes."
- "Let’s switch off the overheads and use lamps."
Scientific Context
Associated with differences in sensory gating, salience networks, and autonomic arousal. Environmental adjustments are evidence‑supported first-line strategies.
Language Notes
Related: sensory seeking, avoidance, and modulation differences.
Related Terms
Sensory Processing Disorder
A condition in which the brain has trouble receiving and responding to information that comes in through the senses.
Autistic Meltdown
An involuntary state of overwhelming distress in which an autistic person temporarily loses the ability to self-regulate, often resulting in crying, shouting, pacing, or other intense behaviors.
Autistic Shutdown
An involuntary response to overload where an autistic person becomes very quiet or unresponsive, withdrawing to protect themselves and reduce input.
Stimming
Repetitive body movements or sounds that help regulate sensory input and emotions.
Accommodations
Changes to the environment, tools, timing, or expectations that remove barriers so a person can participate on an equal basis.
