Environmental Sensitivities – The Definition

scent allergy worriesEnvironmental Sensitivities (ES) describes a chronic condition whereby a person has symptoms when exposed to certain chemicals or other environmental agents, at low levels, tolerated by most people.  The symptoms may range in severity from mild to debilitating.

Some other ways to describe ES:  allergies, environmental illness, Multiple Chemical Sensitivity, chemical intolerance, and environmental hypersensitivity.

Scent Sensitivities – Prevalence*

About 30 per cent of the Canadian population has some type of sensitivity to fragrances. The chemicals in fragrances and scented products can act as irritants and trigger reactions. The number of people with scent sensitivities is growing, a key reason being the vast number of new chemicals compounds created since World War II. Nearly everything now contains chemical fragrances, being present in everything from personal care products to building materials – indoor air can be more polluted than outdoor air.

Another reason is an overload of other stressors, common in our fast-paced world, including a lack of sleep, a lack of physical activity, poor nutrition or emotional stress, can “tip the scales,” resulting in exhaustion and illness.

Approximately 3% of Canadians have been diagnosed with ES. It can affect everyone, but the prevalence increases with age, and 60-80% of those diagnosed are women.
