Can endocrine-disrupting chemicals in household products affect infant sleep patterns?

What's actually in it

Babies are exposed to a mix of environmental chemicals from household products, furniture, personal care items, and food. These include phthalates, PFAS, flame retardants, and bisphenols. Together, this cocktail of chemicals forms what scientists call the "exposome," the total chemical burden a baby carries. Sleep is one of the most important functions for infant brain development.

What the research says

A 2026 study in J Sleep Res used an exposome approach to examine how environmental chemical exposure affects infant sleep. The researchers found that babies with higher overall chemical exposure had more sleep disturbances, including trouble falling asleep, shorter sleep duration, and more frequent night waking.

Poor sleep in infancy can affect brain development, growth hormone release, and immune function. The study found that the combined exposure to multiple chemicals, rather than any single one, was most strongly linked to sleep problems.

Create a low-chemical sleep environment for your baby. Use organic cotton sheets and pajamas. Skip fragranced laundry products. Keep the nursery well-ventilated and use a HEPA air purifier.
