When the World Is Too Loud
What is sensory overload, and how does it affect people at work?
Sensory overload happens when the brain receives more sensory input than it can comfortably process, from noise, bright or flickering lighting, strong smells, or the constant movement of a busy open-plan office. Many neurodivergent people experience it intensely because the filter that dials down background input works differently, so the volume of the world stays turned up. At work it causes genuine exhaustion, difficulty concentrating, irritability and, over time, a real toll on mental health. Simple adjustments, such as quiet spaces, noise-cancelling headphones and flexibility over where focused work happens, make a significant difference at little or no cost.
Here's how I explain it in training. Imagine trying to write an important email while someone flickers the lights and plays three radios at once. You'd manage a sentence or two, at enormous effort, and by lunchtime you'd be spent.
For some of your colleagues, that's just Tuesday. The office isn't hostile on purpose. It was simply designed for one kind of nervous system, and it's staffed by several.
The part most workplaces miss is that sensory overload is invisible right up until it isn't. What you see is a colleague who seems distracted, short-tempered or "not a team player" because they've got headphones on again. What's actually happening is someone spending enormous energy just filtering the environment, energy that isn't going into their work. All behaviour is communication, and this behaviour is saying the environment costs me more than it costs you.
The fixes are rarely expensive. A quiet corner that's genuinely available. Headphones without side-eye. Permission to book the small meeting room instead of the echoing one. Focus days at home. Small environmental changes, big human difference, and here's the pattern I see every time: adjustments made for sensory needs end up helping the whole team concentrate better.
