Teens Who Use Mobile Devices After Bedtime at Increased Depression Risk
A new study in the Journal of Pediatric Psychology has found that teenagers in Japan who use cell phones or other mobile devices after they go to bed face a higher risk of having sleep problems and related mental health problems including depression. From Boston.com:
In the study, researchers investigated nearly 18,000 children in junior high and high schools in Japan, with subjects answering questions about their mental health, in addition to sleep and mobile phone habits. The study follows prior research that finds poor sleep is associated with mental problems in teens. For example, a study published last year in the Journal of Psychiatric Research found teens who had difficulty sleeping were at an increased risk for suicidal thoughts.
