Are flame retardants in furniture tied to ADHD in kids?

What's actually in it

Your furniture often contains organophosphate ester flame retardants and plasticizers. These chemicals are added to foam and upholstery to meet flammability standards. They don't stay in the furniture. Over time, they break down and escape into your home environment.

These chemicals settle into your house dust, which is where children are most exposed. According to a 2026 study in the Journal of Exposure Science & Environmental Epidemiology, these substances are common in indoor environments. Once they are in the dust, they are easily inhaled or ingested by kids playing on the floor.

What the research says

A 2026 study in the Journal of Exposure Science & Environmental Epidemiology found a clear link between these flame retardants in house dust and scores on the Child Behavior Checklist. This checklist is a standard tool used to track behavioral problems in children.

The science shows that these chemicals affect more than just behavior. A 2026 study in Environmental Pollution examined how prenatal exposure to these same flame retardants impacts child cognition. Additionally, a 2026 study in Environmental Research found that exposure during pregnancy is tied to changes in child growth, including weight and body mass index.

Even when you try to remove these chemicals, they persist. A 2026 study in Environmental Pollution looked at how replacing furniture affects your exposure levels. The research confirms that these chemicals are a systemic issue in modern homes.
