The effects of digital screen time on children's well being and development is a source of huge debate at the moment. While concerns over the effects of these new devices on childhood development are not unwarranted, scientists have not been able to reach a clear consensus on the topic. Now a new study by the University of Oxford, examining data from over 350,000 subjects in the UK and US, finds digital technology use accounts for less than half a percent of a young person's negative mental health. The research suggests everything from wearing glasses to not getting enough sleep have bigger negative effects on adolescent well being than digital screen use. Binge-drinking and marijuana use also were noted as having significantly larger negative effects, and bullying was found to have four times larger the negative effect on well being than digital screen use. On the positive end of the spectrum, things like eating a good breakfast and getting enough sleep were much more statistically relevant in affecting well being than the effects of technology use.
