Teens who use mobiles after ‘lights out’ may struggle with sleep, depression

A new Japanese study finds that teens who use their mobile phones late at night may have an increased risk for not only sleep deprivation but also mental health issues.
Published in the October issue of the Journal of Pediatric Psychology, researchers found a link between teens who used mobile phones after they went to bed and poor mental health and suicidal thoughts compared to those who did not use their phones at this time of night. The researchers controlled for other factors, including alcohol and drug usage.
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.
Additionally, Rensselaer Polytechnic Institute’s Lighting Research Center found that looking at the backlit screen of certain electronic devices can suppress melatonin, a hormone produced during sleep, and cause sleeplessness. This study was published recently in the journal Applied Ergonomics.
THE spate of deaths among young people in Britain’s suicide capital could be linked to radio waves from dozens of mobile phone transmitter masts near the victims’ homes.

He has examined worldwide studies linking proximity of masts to depression. Dr Coghill’s work is likely to trigger alarm and lead to closer scrutiny of the safety of masts, which are frequently sited on public buildings such as schools and hospitals.
It is also likely to fuel more campaigns against placing masts close to public places on health grounds.
