"Cut social media for three weeks to lift mood Meta-analyses published in 2025, pooling results from dozens of social media reduction experiments, showed a consistent pattern. According to Twenge, both reviews found "a significant reduction in depression and then a significant increase in psychological well-being — happiness, life satisfaction — when people give up or cut back on social media, especially if they do that for three weeks or more." The threshold matters: short breaks of a few days showed weaker effects, so a committed three-week reduction is the minimum dose likely to produce measurable happiness gains.
