Smartphones can cut your kid’s sleep, layer on the pounds

Sleepy kids may have a hard time hitting the basketball court or focusing on their homework. And the source of their problems may radiate from the digital world of their smartphones! DrLullaby’s founder, Lisa Medalie, PsyD, DBSM contributes to this Medill Reports Chicago article, explaining the harm of the “blue light” emitted from electronic devices such as the iPad, Kindle, or any smartphone on our sleep cycles. The research demonstrated that the “blue light” emitted from electronic devices such as the iPad, Kindle or any smartphone has an effect on sleep cycles. The findings of the study are published in the Proceedings of the National Academy of Sciences. “The blue spectrum light that projects from such screens sends a message to the brain to stop secreting melatonin,” explained Dr. Lisa Medalie, a behavioral sleep medicine specialist at the University of Chicago. “If we expose ourselves to such light leading up to bedtime, clearly that would interfere with our sleep,” said Medalle, who wasn’t associated with the study.
