Multiple Chemical Sensitivities (MCS)

Multiple Chemical Sensitivities (MCS)

MCS Referral and Resources defines multiple chemical sensitivity as “a chronic condition marked by heightened sensitivity to multiple different chemicals and other irritants at or below previously tolerated levels of exposure. Sensitivity to odors is often accompanied by food and drug intolerances, photosensitivity to sunlight and other sensory abnormalities, such as hypersensitivity to touch, heat and/or cold, and loud noises and impaired balance, memory and concentration.”

People with MCS become ill from eating, breathing, or absorbing even small amounts of chemicals; their reactions can range from mild to severe, and may be immediate or delayed.
