Why This Matters<\/div>

Why Research on MCS Matters<\/h1>

Multiple Chemical Sensitivity (MCS) is a chronic condition and recognized disability in which individuals experience multisystem symptoms triggered by volatile organic compounds (VOCs) and other chemicals at low levels of exposure. Despite a growing body of evidence, MCS remains underrepresented in clinical training, public health policy, and research funding.<\/p><\/div> \t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
