In the quiet of summer, a familiar comfort has taken on a more troubling dimension. Researchers have begun documenting measurable structural changes in the brains of heavy binge-watchers — changes that echo patterns associated with dementia and cognitive decline — while children, whose neural architecture is still forming, face compounding risks to their sleep, metabolism, and academic development. The screen, long treated as a harmless reprieve, is now asking a deeper question: what are we trading away in those long, glowing hours?
