More people have sensitivities to scents than you might think. While you might believe you’re doing the world a favor by spraying down your living space with air fresheners, some people don’t take to artificial scents very well. In fact, surveys of over 2,000 Americans found that almost 20 percent of respondents reported adverse health impacts from air fresheners.
For asthmatics, this number is substantially higher. One study found that 64.3 percent of asthmatics reported one or more types of adverse health effects stemming from exposure to fragranced products.
