chemical sensitivity: meaning, definition, pronunciation and examples

No. Allergies involve a known immune system response (e.g., IgE antibodies). Chemical sensitivity reactions are broader, often involving the nervous system, and occur at exposure levels far below those that cause toxic effects, without a standard immune marker.

It is a recognized syndrome (Multiple Chemical Sensitivity), but its classification is controversial. Some medical bodies view it as a legitimate chronic condition, while others classify it as a set of symptoms without a clear organic cause. It is often recognized for disability accommodation purposes.

Common triggers include pesticides, synthetic fragrances (in perfumes, detergents), tobacco smoke, vehicle exhaust, cleaning products, solvents, and new building materials (e.g., carpet, paint).

There is no standard cure. Management focuses on avoidance of triggers (creating a 'chemical-free' living space), supportive therapies (counselling for coping), and sometimes detoxification or nutritional support regimes, though these are not universally accepted by mainstream medicine.

An adverse physiological reaction to exposure to certain chemicals at levels that are generally tolerated by most people.

Chemical sensitivity is usually medical/health/environmental; formal/technical in register.
