International prevalence of fragrance sensitivity

Emissions and exposures from fragranced consumer products, such as air fresheners and cleaning supplies, have been associated with health problems and societal impacts. This study investigates effects of fragranced consumer products on the general population in four countries: United States, Australia, United Kingdom, and Sweden. Nationally representative population surveys (n = 1137; 1098; 1100; 1100) found that, across the four countries, 32.2% of adults (34.7%, 33.0%, 27.8%, 33.1% respectively) report fragrance sensitivity; that is, adverse health effects from fragranced consumer products. For instance, 17.4% report health problems from air fresheners or deodorizers, and 15.7% from being in a room cleaned with scented products. Commonly reported health problems include respiratory difficulties (16.7%), mucosal symptoms (13.2%), migraine headaches (12.6%), skin rashes (9.1%), and asthma attacks (7.0%). For 9.5% of the population, the severity of health effects can be considered disabling. Further, 9.0% of the population have lost workdays or lost a job, in the past year, due to illness from fragranced product exposure in the workplace. Personal estimated costs due to these lost workdays and lost jobs, across the four countries in one year, exceed $146 billion (USD). A majority of people across the countries would prefer that workplaces, health care facilities and professionals, hotels, and airplanes were fragrance-free rather than fragranced. The study highlights a concern for public health and societal well-being, as well as an approach to reduce risks and costs: reduce exposure to fragranced products.
