Can flame retardants in children's bedrooms cause sleep problems?

What's actually in it

Organophosphate ester flame retardants are added to mattresses, foam padding, upholstered furniture, and electronics. They off-gas into indoor air as tiny particles that settle as dust and get inhaled. Children breathe these chemicals all night long while sleeping.

Kids spend 10 to 12 hours in their bedrooms each day. That's a long, concentrated exposure to whatever chemicals are in the air.

What the research says

A 2026 study in Toxics measured organophosphate ester levels in the air and linked them to childhood sleep disorders. The researchers assessed sleep quality, time to fall asleep, and nighttime awakenings.

Children with higher exposure to organophosphate esters had more trouble falling asleep, woke up more during the night, and had lower overall sleep quality.

These chemicals can disrupt sleep by interfering with acetylcholine signaling in the brain, the same neurotransmitter system that organophosphate pesticides target. At low doses, the effect is subtle but measurable.

Improving your child's sleep environment can help. Choosing mattresses and furniture that are certified low in flame retardants, airing out new furniture before use, and keeping bedrooms well-ventilated all reduce exposure.
