01 · Definition
What is sensory overload?
Sensory overload describes feeling unable to comfortably process the amount or intensity of sensory input around you. Sound, light, touch, smell or several inputs together may contribute. A person may want less input in one setting and more in another.
Sensory experiences vary and are not unique to ADHD. A product’s calming appearance or noise label cannot establish that it will suit your needs.

What does research say about sensory overload?
These sources address different parts of the topic. The study design and population matter when deciding what a finding can tell you about everyday support.
Transdiagnostic patterns of sensory processing in autism and ADHD
2024 · Research on sensory processing patterns
Findings: This research examines sensory processing across autism and ADHD, rather than treating sensory differences as belonging to only one diagnosis.
Limitations: Group patterns cannot prescribe an individual sensory adjustment. They do not prove that a particular headphone, light or sound will improve comfort or attention.

04 · Practical guide
How to manage sensory overload
1. Identify one difficult input
Notice what is happening in the setting and what changes your comfort.
Example: You can read in the room until several conversations start nearby.
2. Change one part of the setting
Try a quieter location, different lighting or another practical adjustment.
Example: Move to a quieter corner before adding headphones or another sound.
3. Review comfort and access
Check whether the change helps and whether you can still hear necessary signals.
Example: Keep a route for a colleague to get your attention without constant alerts.
These examples are illustrative. Adjust the steps and timings to your situation.
When to adjust the approach
Sensory experiences vary and are not unique to ADHD. A product’s calming appearance or noise label cannot establish that it will suit your needs.
Evaluate one situation at a time. If the change adds more effort than it removes, simplify it or ask what is still making the task difficult.

05 · Choosing a tool
What to look for in a sensory overload tool
- Adjustable intensity and an immediate off switch
- Trials and returns for physical products
- Clear sound controls and no forced sensory effects
Start with what you already have. A tool earns its place when it makes your chosen approach easier to use.
