The 3pm you can’t account for
By 3pm on the open-plan floor you’ve stopped being able to read. The air conditioning, the 2 conversations behind you, someone’s video call on speaker, the overhead lights humming at a pitch nobody else seems to hear, the seam of your shirt collar. None of it is loud. All of it is arriving at full volume and none of it is leaving. The email you’re writing has been the same 2 lines for 20 minutes.
Your nervous system takes in an enormous amount of information every second: sound, light, smell, texture, temperature, the feel of your own clothes, the hum of a fridge you stopped hearing hours ago. Most brains filter most of it out automatically. Many autistic brains filter less, or filter differently, so more of it comes through at full strength and stays there.
Sensory overload is what happens when that incoming volume outpaces what you can process. A real limit gets exceeded. That’s the whole mechanism, and drama has nothing to do with it.
What it feels like from inside the meeting
The world gets loud even when it isn’t. Sounds sharpen into something almost physical. Lights press on your eyes. A label or a seam you tolerated an hour ago becomes intolerable. Your thoughts stop lining up, speaking gets harder, then maybe impossible, and you feel irritable, panicky or trapped without being able to say why, because the part of you that explains things has gone offline. In a client meeting this reads as someone who has suddenly gone quiet and terse. From the inside it’s a system throwing errors.
For some people this crests into a meltdown: an involuntary overflow that can look like tears or anger. For others it’s a quiet shutdown, going still and far away. They’re what a maxed-out system does to protect itself; neither one is a tantrum, and neither one is a choice.
The usual suspects, office edition
Triggers are personal, but some show up again and again: crowded, echoing spaces (the expo hall, the station at rush hour, the supermarket on the way home, the hotel bar after the conference); fluorescent lighting and screen glare; overlapping conversations you can’t tune out; strong smells; scratchy or tight clothing; heat; and the slow grind of a 10-hour day with no quiet anywhere in it.
Usually it’s accumulation: a dozen small inputs stacking up until an ordinary noise becomes the one that tips you over. That’s why the crash after a 3-day conference can seem to come from nowhere. It didn’t. You’d been filling up since the keynote.
Taking inputs off the pile
Pushing through is what got you here, so the useful direction is to remove inputs, before and during.
Reduce at the source. Free first: overhead lights off if you control them, a desk facing away from the window, foam earplugs from the pharmacy, the call taken from the room with a door. Then the bought versions some people rely on: filtered earplugs that lower the room without cutting you off, tinted or polarized glasses for glare, over-ear headphones for when earplugs aren’t enough, and at home a weighted blanket (or the heaviest duvet you own) for an overloaded body to settle against. The claim for all of these is modest. The volume goes down, so you have more room to cope. Bare minimum: earplugs in a pocket, used once.
Leave early and without apology. The bathroom, your car, a stairwell, the sidewalk outside. A few minutes of low input can stop a wobble from becoming a crash. Planning the exit in advance (which door, and what you’ll say) is maintenance, and nobody at the dinner will notice a 5-minute absence.
Build quiet in on purpose. If Thursday is the all-hands and the client dinner, protect Friday morning. Recovery after a loud day is how the system balances. Bare minimum: no calls in the first hour of the next day.
Name it to the people who’ve earned it. “I’m getting overloaded, I need 10 minutes” is a full sentence. The right colleagues would rather have that than an unexplained bad mood.
Give your hands an outlet. Stimming (repetitive movement like tapping, rocking or fidgeting) is how a lot of autistic people regulate. A pen or a paperclip works for free; some people keep a discreet fidget or a chewable for when the room is loud and leaving isn’t an option.
Where a clinician fits, and where disclosure does
If overload is seriously disrupting your working life, a neurodiversity-affirming professional is one option for building a plan that fits you. Honest limits: it takes time and often money, and no plan changes the acoustics of your floor. Formal adjustments (a desk move, remote days) are a separate route that usually goes through HR and usually needs documentation, which is one reason some people pursue assessment. Disclosure is your call, with real trade-offs in both directions. This is education and lived experience, and it isn’t medical advice.
Sensory stuff overlaps heavily with ADHD, and the two can amplify each other; the ADHD primer and AuDHD overview both cover the crossover.
The sensitivity itself
If you’ve spent a career being told you’re too sensitive: the sensitivity is how you’re wired, and it comes bundled with noticing what everyone else in the room misses. Overload is the cost side of that. You’re allowed to protect it.
One thing to do before the next big day: work out where the nearest door with a lock is, and what you’ll say when you use it.
