Can laundry detergent and fabric softener impair your child's breathing?
Yes. Children in homes using certain laundry detergents and fabric softeners had reduced lung function compared to those using gentler products.
What's actually in it
Laundry detergents and fabric softeners contain fragrances, surfactants, preservatives, and optical brighteners. These chemicals don't fully rinse out. They stay in the fabric and slowly off-gas or transfer to skin. Children breathe these chemicals in from their clothes, bedding, and towels all day and night.
Fabric softeners are especially concerning because they're designed to coat fabric fibers with a thin layer of chemicals that remains after washing.
What the research says
A 2026 study in Ann Allergy Asthma Immunol examined laundry washing habits and lung function in children. Kids in households that used certain conventional detergents and fabric softeners had measurably lower lung function compared to children whose families used fragrance-free or gentler alternatives.
The effect was strongest in children who already had asthma or allergic tendencies. The fragrance chemicals and surfactant residues in clothes acted as respiratory irritants, triggering airway constriction and inflammation with every breath.
Switching to fragrance-free, hypoallergenic detergent and skipping fabric softener entirely can improve indoor air quality and reduce chemical residues on your child's clothes and bedding. Running an extra rinse cycle also helps wash out more residual chemicals.
