Digital screen time linked to brain changes and economic loss

High levels of screen time and digital overstimulation are linked to significant health and economic consequences. Research from Stamford’s Lifestyle Medicine team indicates that heavy screen exposure may lead to the thinning of the cerebral cortex, an area of the brain responsible for memory and decision-making, and can negatively impact sleep quality.

In the United States, a 2025 survey by Harmony Healthcare IT found that the average person spends 5 hours and 16 minutes on their phone daily. This habit also carries a professional cost; a study by Payless Power suggests that Americans average 3.5 hours of doomscrolling during the workweek, which costs employers an estimated $5,600 per employee annually.

Strategies to mitigate these effects include using grayscale mode to make displays less visually stimulating, turning off non-essential notifications, and setting intentional boundaries to reclaim time for physical activities and social interaction.
