Sensory economy - Do you understand your sensory system?
She thought she was getting ill.
Every Tuesday afternoon, she'd come home from work and go straight to bed. Exhausted in a way that sleep didn't fix. Some days irritable for no reason she could name. Some days she'd just sit, staring, unable to start anything, unable to want anything. Her GP found nothing. She started wondering if it was depression.
It wasn't depression.
It was the open-plan office. The fluorescent lights. The colleague who ate crisps at 2pm. The thirty-seven conversations happening at once. The cold air from the vent directly above her desk. By Tuesday afternoon, her nervous system had been running on overdrive since Monday morning — and nobody had told her that was even possible.
Here's what most of us were never taught: sensory input doesn't just pass through us. It accumulates. And for an ADHD brain — a brain that often can't filter what comes in — that accumulation has a cost. It shows up as fog. As exhaustion. As snapping at someone you love. As sitting in front of a task you know how to do and being completely unable to begin.
We call it laziness. We call it mood. We call it a bad day.
It's a depleted nervous system that never got the chance to recover.
Understanding your sensory economy — what fills you, what drains you, how much you can hold before the system tips — isn't self-indulgence. It's the foundation everything else is built on.
She didn't need to push harder. She needed to know herself better.
We just finished our second group coaching session. Brilliant group, we learnt so much from each other.
