Use of Media Devices Affect Teens’ Sleep Significantly.
A Norwegian study has found that if it takes more than an hour for a teenager to fall asleep, there is an almost 50% likelihood that they are spending more than four hours per day outside of school using electronic devices such as computers, TVs, smartphones, and MP3 players. The findings are of concern since the majority of teens in the United States report having at least one electronic device in their bedroom, and poor sleep has implications on school performance. The authors add, “The current recommendation is not to have a TV in the bedroom. It seems, however, that there may be other electronic devices exerting the same negative influence on sleep, such as PCs and mobile phones. The results confirm recommendations for restricting media use in general.”
