5. Cognitive Effects and Attention Span

High screen use has been associated with reduced attention spans, increased multitasking, and a diminished ability to concentrate for extended periods. Modern digital environments encourage rapid task-switching, which can undermine deep focus and sustained engagement, contrasting sharply with pre-digital learning and work settings that often favored undivided attention.
A study published by the National Institutes of Health highlights the cognitive challenges posed by constant screen exposure, suggesting that these shifts may affect memory retention and overall productivity in both educational and professional contexts.
