What Is Multiple Chemical Sensitivity?

MCS is a chronic condition where everyday low-level chemical exposures — fragrances, cleaning products, exhaust — trigger real, sometimes disabling symptoms most people never notice. It's documented in medical literature and recognized as a disability in multiple jurisdictions.

What are the symptoms of MCS?

MCS is multi-system: neurological, respiratory, fatigue, gastrointestinal, cardiovascular, sensory, and more. A single low-level exposure can trigger symptoms that persist for days or weeks.

What triggers MCS reactions?

Fragrances, cleaning products, pesticides, smoke and combustion, building materials and VOCs — everyday low-level exposures that most people never notice.

What does the science say about MCS?

What is happening to you is real. It is not in your head, it is not imagined, and it is not your fault. Brain scans of people with MCS show their brains responding differently to chemical exposures.[2] Immune tests show their bodies releasing inflammatory chemicals at exposure levels that do not affect other people.
