Understanding the Sensory Crash

Understanding the Sensory Crash — Educational Infographic (Printable, A2)

You will receive the printable unwatermarked version of this infographic

An in-depth visual walking through the sensory crash as a five-stage overload journey — from "all is OK" to "the crash" — showing it's not behaviour, it's the nervous system at breaking point.

This infographic covers:

• The overload journey: all is OK → building load → system strain → overwhelmed → the crash
• What happens inside the body: outward systems slowing down (movement, processing, speech) while inward systems surge (cognition, emotions, alert system, amygdala activation)
• What the crash looks like, and why it's not attention-seeking or naughty — it's neurological collapse
• The science behind the crash: the core mechanism, the overload point, amygdala on high alert, inward systems overload, the nervous system forcing a reset
• Early signs to watch for: covering ears, pacing, increasing stimming, facial tension, going quiet suddenly
• Adult response — regulation first: remove/reduce the trigger, lower sensory load, offer deep pressure, use a calm voice, co-regulate with connection
• Recovery stage after the crash, and what helps most: movement, deep pressure, quiet spaces, predictable routines, time to recover

What you get:

• High-resolution PDF, print-ready and scalable up to A2 (420 × 594mm)
