(c) The sensory world
A world turned up too loud
For many autistic people, the world arrives at full volume. A flickering fluorescent tube, a humming fridge, the scratch of a clothing label, overlapping conversations in a cafe — each one competes for attention, and none of them fades into the background the way it does for most people.
Sensory sensitivity works in both directions. The same nervous system that is flooded by a supermarket can be soothed by a favorite texture, a repeating sound, or the exact pressure of a weighted blanket. The goal is never to remove sensation — it's to give the person control over it.

Overload
When sensory input stacks up faster than it can be processed, the nervous system goes into alarm. A meltdown or shutdown isn't a tantrum or a choice — it's what overload looks like from the outside, and it's usually followed by deep exhaustion.
Stimming
Rocking, hand-flapping, pacing, humming, fidgeting — repetitive movement and sound that self-regulates the system. Stimming is healthy and helpful; suppressing it costs far more than it ever gains.
Quiet as access
A quiet room, dimmed lights, noise-cancelling headphones, a seat by the exit — these aren't luxuries. For an autistic person they're the difference between participating and merely surviving the room.
Try feeling it, briefly
Imagine trying to follow a conversation while a radio plays in another language, a light flickers overhead, your sock seam presses into your toe, and someone keeps asking you questions. Now imagine you can't ask any of it to stop. That's an ordinary Tuesday for many autistic people — and it's why "just pay attention" is often not a fair request.
