The Science Behind Meltdown vs Shutdown

The Science Behind Meltdown vs Shutdown — Educational Infographic (Printable, A2)

You will receive the printable unwatermarked version of this infographic

A clear visual explainer showing that meltdown and shutdown come from the same nervous system overload — the difference is how the body expresses it, not how much distress there is.

This infographic covers:

• Meltdown: outward expression of overload (crying, shouting, pacing, pushing away, discharging input)
• Shutdown: inward expression of overload (going quiet, freezing, withdrawing, slow processing, conserving energy)
• What's happening underneath: sensory/emotional load builds → brain reaches threshold → thinking brain access drops → survival response takes over
• Same root, different expression: energy outward vs. inward, distress loud vs. quiet, body discharges vs. withdraws
• What helps both: reduce demands, lower sensory input, calm minimal language, offer safety without pressure, allow recovery time, co-regulate first
• Key takeaway: meltdown and shutdown are not opposites — neither is better or worse, both need safety, understanding, and recovery
