Parents have long known that too much screen time can leave kids moody or distracted. What scientists are now discovering is how deeply those effects can reach. Clinical neuropsychologist Amanda Sacks-Zimmerman from Cornell University in New York, reports that brain scans reveal measurable differences between children immersed in digital worlds and those who spend more time in active, real-life play.

Her findings show that the parts of the brain responsible for language, empathy and planning develop differently when a child’s daily world is mostly two-dimensional. Children who read, build, move and explore physical spaces form stronger connections in the regions of the brain that support focus and problem-solving, while those who mainly consume digital content often show weaker activity there.

Sacks-Zimmerman cautions that the goal is not to eliminate technology but to restore balance. “Technology has made it easier to communicate,” she notes: “but harder to truly connect.” Families can start small by bringing back routines that encourage real interaction. Reading aloud, helping in the kitchen or playing outside all engage the brain in ways that screens cannot replicate.

She also recommends setting moments for devices to rest, during meals, before bedtime or while walking together, to let the brain reset. Even brief breaks strengthen attention and creativity.

The encouraging news, Sacks-Zimmerman says, is that children’s brains are resilient. The same flexibility that allows screens to shape development can also reverse unhealthy habits. Real-world conversation and play remain the strongest builders of empathy, focus and imagination. As she reminds parents: “The brain grows where it’s used most.” By giving children more chances to move, talk and create, families can help digital natives stay connected to what matters most, real life.
