MCS (Multiple Chemical Sensitivity)

A trace of perfume in the elevator. The smell of fresh wall paint. A new piece of furniture off-gassing. What other people barely even notice sends your body into a state of alarm. Headaches, dizziness, nausea, shortness of breath, skin reactions, exhaustion — your system responds to substances present in concentrations far below any toxicological threshold. Medicine often faces this phenomenon with bewilderment: there is no clear biomarker, no uniform diagnosis, no well-defined mechanism. What is measurable does not explain the intensity of your reaction.

And this is precisely where the deeper question begins. Your body reacts — that is real. But what is it actually reacting to? To the chemical? Or to something the chemical symbolises — something that enters from outside and that you cannot control?
