The primary goal was to curb student usage of Instagram and TikTok by imposing a combined daily usage cap of 60 minutes, for two weeks.

After completing the two-week long NOMO challenge, the incidence of feeling depressed nearly halved, dropping from 38.7% to 20.7% (a 47% reduction in depressive symptoms; p-value < 0.001).

Reports of anxiety also eased modestly, and the share of participants who felt easily distracted fell from 47.9% to 36.8% (p-value < 0.01). At the same time, life‐satisfaction incidence climbed from 61.1% to 70.6% (p-value < 0.02).

Together, these shifts suggest that reducing social media helped participants feel healthier, happier and more focused. Participants also experienced productivity gains (measured by test scores) of about 0.8 standard deviation.
