Children may be breathing in harmful chemicals from their mattresses while they sleep, two new studies found.The peer-reviewed studies, published Tuesday in the journal Environmental Science Technology Letters, found that babie s and young children may be absorbing or breathing in plasticizers called phthalates and flame retardants that have been linked to neurological and reproductive problems.Researchers at the University of Toronto measured chemical concentrations in 25 bedrooms of children aged 6 months to 4 years old and found concerning levels of phthalates, flame retardants and UV-filters in the air.The researchers noted that the highest levels of those chemicals were around the beds.RELATED STORY | As measles spreads to another state, how early can babies be vaccinated?Next, the research team conducted a companion study in which they tested 16 newly purchased childrens mattresses and found the presence of these chemicals.The study simulated the weight and temperature of a childs body on the mattresses and found that the chemical emissions increased substantially.While the mattresses used for the study were purchased in Canada, researchers said that most of them contained materials that originated in the U.S. and Mexico.The researchers said these findings are particularly concerning because children are uniquely vulnerable to exposure since they are still developing."Parents should be able to lay their children down for sleep knowing they are safe and snug, said the studies co-author, Executive Director of the Green Science Policy Institute Arlene Blum. Flame retardants have a long history of harming our childrens cognitive function and ability to learn. Its concerning that these chemicals are still being found in childrens mattresses even though we know they have no proven fire-safety benefit, and arent needed to comply with flammability standards.RELATED STORY | 'Operation Stork Speed' aims to improve baby formula safety under RFK Jr.'s leadershipAccording to the research team, there are some things parents can do to reduce their childrens exposure to these harmful chemicals. Those actions include: Decluttering your childs sleeping area by reducing the number of pillows, blankets and toys. Wash and refresh your childs bedding and bed clothing frequently since these act as a protective barrier to reduce exposure. Using undyed or neutral color fabrics is likely safer since keeping strong colors requires the addition of UV-filters and other additives that may be harmful. ...read more read less
