Is it safe to use fabric softeners if a child in the house has wheezing?
Avoid them for now. A 2026 study linked fabric softener and additive-heavy laundry products with worse breathing measures in wheezing children.
What's actually in it
Liquid fabric softeners and dryer sheets leave a coating on fabric. That coating can include cationic surfactants, fragrance compounds, preservatives, and softening agents.
For a child with wheezing, the issue is repeated contact. Pajamas, blankets, towels, and sheets sit close to the nose and skin for hours.
What the research says
A 2026 Annals of Allergy, Asthma & Immunology study looked at 80 children with wheezing and 80 healthy children. Families using softeners and additive-heavy laundry products had children with higher airway resistance on breathing tests. Children using additive-free, soap-based detergents had lower airway resistance.
This does not mean one scented load caused the wheeze. It does support a simple household rule: skip fabric softener and dryer sheets when a child has asthma or recurrent wheezing. Use fragrance-free detergent. Run an extra rinse for pajamas and bedding. Choose washable cotton bedding and baby basics so you do not need softener to make fabric feel comfortable.
