Research published this year reveals that one in three adults report health problems caused by fragranced products, including perfumes, cosmetics, laundry detergents, and soaps. The study, which surveyed over 4,300 people from the UK, US, Australia, and Sweden, found that fragrance sensitivity can trigger migraines, watery eyes, and respiratory issues. Lead researcher Dr Anne Steinemann from the University of Melbourne described it as a healthcare epidemic of unknown scale, calling for clear ingredient labelling on fragrances.
Airports are increasingly addressing the issue, with Helsinki, Vancouver, and Copenhagen offering perfume-free routes for passengers with sensitivities. Some public spaces in North America have also implemented restrictions: hospitals and schools in Halifax, Nova Scotia, ban employees from wearing perfume, and a church in Seattle introduced fragrance-free zones in 2013. These measures highlight a growing recognition of the problem, though the UK has yet to adopt similar policies.
Lesley Heidinger, a 46-year-old call-centre worker from Edmonton, Canada, suffers from multiple chemical sensitivity (MCS), a condition characterised by heightened sensitivity to chemicals in everyday products. Synthetic fragrances cause her sinus irritation, wheezing, coughing, and migraines lasting days. She has been off work for much of the year and had to sell her flat due to shared laundry facilities. On a recent flight, she had to change seats because of a perfumed passenger.
While Heidinger’s MCS is medically recognised, many patients struggle to be taken seriously. A 2011 US study found only 30% of doctors had formal training on MCS, and the NHS does not publish treatment guidelines for the condition. Dr Apelles Econs, an allergy specialist at the Burghwood Clinic in Surrey, notes that people with MCS are 'orphans of conventional medicine' because they are intolerant rather than allergic to chemicals, leading to negative allergy tests.
