Screen time, insomnia and depression in adolescents

Screen time is associated with insomnia and depressive symptoms in adolescents, a new study finds.

Surveying 3,000+ adolescents (mean age 15) about their sleep (issues falling and/or staying asleep, as well as duration), depressive symptoms, and daily screen time (messaging, web surfing, streaming, gaming), American researchers found that the latter mediated a correlation between insomnia and signs of depression.

For each of the four activities, the more time adolescents devoted to them, the more insomniac and the more depressed they were.
