Early Screen Time Linked to Long-Term Brain Changes, Teen Anxiety

New research following children for more than a decade links high screen exposure before age two to accelerated brain maturation, slower decision-making, and increased anxiety by adolescence. Infants with more screen time showed premature specialization in brain networks involved in visual processing and cognitive control, which later reduced flexibility during thinking tasks.

This shows a child, a brain, and screens.

Screen Time in Tweens Predicts ADHD, Slower Brain Growth

A large, two-year study of nearly 12,000 children found that higher screen time at ages 9–10 predicts an increase in ADHD symptoms, independent of a child’s starting symptom level. Brain imaging revealed that heavy screen use is associated with smaller cortical volume and disrupted development in regions critical for attention, cognition, and reward processing.

Addictive Screen Use, Not Time, Tied to Teen Suicide Risk

A major new study reveals that teens who develop compulsive patterns of digital use are at higher risk of suicidal thoughts, attempts, and mental health issues. Unlike total screen time, it’s the addictive nature of use—such as distress when not online or using screens to escape—that most strongly predicts poor outcomes.

Screen Time in Bed Linked to Less Sleep, Higher Insomnia Risk

A new study of over 45,000 young adults found that using screens in bed increases the risk of insomnia by 59% and cuts sleep by 24 minutes. Surprisingly, the type of activity—whether social media, movies, or studying—didn’t make a difference; it was the screen time itself that mattered most.

Removing Pre-Bed Screen Time Improves Toddler Sleep

A world-first trial shows that eliminating screen time in the hour before bed significantly improves toddlers' sleep quality. The study involved 105 families and found that toddlers who replaced screen time with calming, non-screen activities slept more efficiently and woke up less during the night.

Screen Time Linked to Mental Health Symptoms in Kids

A recent study finds that increased screen time is associated with higher levels of depression, anxiety, and attention issues among 9- and 10-year-olds. Following a diverse group over two years, researchers discovered that activities like video chatting, texting, and gaming were most strongly linked to depressive symptoms.

Impulsive behavior linked to sleep and screen time

Too little sleep and too much screen time are linked to increased impulsive behaviors, especially in younger people. Reducing recreational screen time to two hours a day and sleeping for 9-11 hours per night can help curb impulse behaviors.
