POWER OF SLEEP According to a new study, most children’s mattresses emit toxic chemicals associated with developmental and hormonal disorders, “We measured chemicals in the air of 25 children’s bedrooms between the ages of 6 months and 4 years and found worrisome levels of toxins,” said study author Miriam Diamond, a professor at the University of Toronto. Diamond’s team tested 16 new mattresses and found those to be a key source of exposure. They also discovered that the warmth and weight of a sleeping child increased the off-gassing of toxicants. While the study did not publish brand names, researchers disclosed that the mattresses were well-known models commonly sold across North America. “Every mattress we studied emitted toxins, something children are especially vulnerable to due to their rapidly developing brains and bodies,” Diamond said.

For example, one mattress emitted 1,700 parts per million of a polybrominated diphenyl ethers, or PBDE, known as organophosphate ester, which is a known carcinogen. Another mattress contained 1,800 parts per million of pentachlorothiophenol, or PCTP, one of five flame retardants banned by the EPA. “The big takeaway is that we need stronger standards for toxic additives in children’s products — especially in products that sit inches from a child’s nose and mouth for hours every day,” she added. “Parents should prioritize toxin-free options, and companies should also do their part by removing unneeded chemicals and working toward products that are truly non-toxic.”
