Lead Exposure Affects Children's Sleep

11/16/2015

A new study from the University of Pennsylvania School of Nursing shows that lead exposure in early childhood can cause sleep problems 113837432_SLEEP_340484c.jpgand excessive or abnormal daytime sleepiness when the children are older. The research was based on of a previous study done in China that looked at how lead affects overall development, but this is the first longitudinal, population-based study to examine the connection between lead exposure and sleeping problems.  

Reports of insomnia and the use of sleeping pills were two to three times higher in children with a blood lead level (BLL) above 10 μg/dL, when compared to children with lower BLLs. Sleep problems have been shown to increase developmental, intellectual and neurocognitive issues in growing children and adults. Dr. Liu, the study's principal investigator, says that, "Insufficient sleep and daytime sleepiness is very prevalent in children and adolescents, and it is a pervasive problem that is linked with a significant public health burden."
