Digital Detox Programs Show Cognitive Rebound Effects After 72 Hours

A controlled study of 340 participants at Stanford found that structured disconnection from screens and notifications produces statistically significant improvements in working memory and sustained attention, but only when the detox period exceeds 72 continuous hours. Shorter breaks showed no measurable benefit compared to control groups. The findings challenge the popular notion that even brief digital breaks are restorative and suggest that meaningful cognitive recovery requires a deeper commitment to disconnection.
