chemical sensitivity

Adverse compound reactions

Chemical sensitivity is a condition in which exposure to low levels of common substances—fragrances, cleaning products, pesticides, or synthetic materials—triggers physical symptoms like headaches, fatigue, or respiratory distress.

The medical establishment remains divided on whether the condition has physiological causes or is primarily psychosomatic.

Also called multiple chemical sensitivity or MCS.
