Is it safe to wear flame-retardant-treated kids' pajamas to bed?
Based on 1 peer-reviewed studybaby
Verdict: Avoid
Not ideal. Flame retardants transfer to skin during sleep, especially when kids sweat.
What's actually in it
Kids' pajamas that are loose (not tight-fitting) carry added organophosphate flame retardants to meet U.S. safety rules. Pressed against warm, sweaty skin for 8 to 12 hours a night, flame retardants transfer onto the body.
What the research says
A 2025 study in Sci Total Environ showed sweat amplifies flame retardant transfer, and the mix of OPEs and PFAS was more toxic than either alone.
Choose tight-fitting organic cotton pajamas, which are exempt from flame retardant requirements in the U.S. Or wool sleepwear, which passes fire safety naturally.
