The EPA’s own research has shown that indoor air is often **2–5 times more polluted** than outdoor air — and in some homes, up to 100 times worse immediately after doing laundry with scented products.
In one University of Washington study, the air inside a home after using scented laundry products contained higher levels of certain VOCs than standing next to a busy highway.
The Health Impact You Can’t Smell
The symptoms are familiar to millions:
– Headaches and brain fog
– Worsening asthma and allergies
– Skin rashes and eczema flare-ups
– Hormonal disruption (some fragrance chemicals are phthalates or musk compounds that mimic estrogen)
– Increased cancer risk with long-term exposure
Fragrance sensitivity now affects an estimated **30–35% of the population**, according to studies in the U.S. and Europe, and many people with asthma list fabric softener as a top trigger.
Children, whose lungs and detoxification systems are still developing, are especially vulnerable. A 2020 study in *Environmental Health* linked early-life exposure to fragrance chemicals with higher rates of wheezing and respiratory issues.
