A large Norwegian study found that college students who exercised less were significantly more likely to develop depression or anxiety. Daily exercise and meeting WHO activity guidelines were both tied to lower risk. Consistent, moderate movement — not extreme workouts — may be the sweet spot for student mental health.
A prospective cohort study of over 53,000 Norwegian higher education students found a clear link between physical inactivity and a higher risk of common mental disorders (CMDs), including major depression and generalized anxiety disorder. Students who seldom or never exercised were significantly more likely to develop a CMD compared to those who exercised daily — with the effect especially pronounced in men.
The study, published in PLoS One, tracked participants over one year and assessed exercise habits against WHO guidelines (at least 150 min/week of moderate-to-vigorous activity). Results showed that both low exercise frequency and failing to meet weekly activity recommendations elevated CMD risk across sexes. Interestingly, for women, the mental health benefit plateaued at around 5–6 hours of exercise per week, while men continued to see risk reductions with higher volumes.

Why it matters: With mental health challenges rising among college-aged populations, this study highlights exercise as a practical, scalable intervention. Clinicians and campus health programs should prioritize promoting consistent, attainable physical activity routines — not just high-intensity regimens — as part of broader student mental health strategies.
