Too much screen time can be physically changing youth’s brains, early study finds

Too much screen time can physically change your child’s brain: A study funded by the National Institute of Health suggests that teenagers and adolescents’ heavy use of smartphones, tablets and computer screens can be damaging to their brains, according to Bloomberg. While the findings cannot yet be considered conclusive, the study found that children who spent more than seven hours a day on screens had a thinning brain cortex, the outermost layer that processes information from the physical world (watch, runtime: 1:13).
