Are synthetic fragrances in laundry detergents harmful to a baby's respiratory health?

What's actually in it

Most conventional laundry detergents and fabric softeners rely on synthetic fragrances to mask odors. These chemicals are not inert. They linger on fabrics and release particles that babies breathe in all day and night. When these products are used, they can change how a child's lungs work and make their airways more sensitive to other irritants in the air.

What the research says

A 2026 study in Ann Allergy Asthma Immunol found that the use of laundry detergents and softeners is directly linked to impaired respiratory functions in children who already suffer from wheezing. These products essentially make it harder for children with sensitive lungs to breathe.

The impact goes beyond just irritation. A 2026 study in Allergy shows that laundry detergents actually enhance the body's reaction to other allergens in the air. In tests, these detergents made airway inflammation much worse. By using these products on baby clothes and bedding, you are creating an environment that makes your baby's lungs more reactive and prone to inflammation.
