In November 2018 researchers from Australia and the USA published the results of their study to assess the incidence and types of health problems associated with exposure to fragranced products among asthmatic Australians. A total of 1,098 individuals were included in the study, of which 28.5% were medically diagnosed with asthma or an asthma-like condition. Information on the effect of fragranced products was collected via an online survey. Results showed that 57% of asthmatics, and 24% of non-asthmatics experienced adverse effects after exposure to fragranced products, with 24% of asthmatics reporting an asthma attack. In addition, over 20% of asthmatics reported that they were unable to access public places and restrooms that use air fresheners. It was also noted that 18% of asthmatics had lost workdays or a job in the past year due to fragranced products in the workplace. Most asthmatics would prefer workplaces, healthcare facilities, and environments that are fragrance-free, which could help reduce adverse effects.
