Exercise May Shield College Students From Depression and Anxiety, Study Shows

When the semester feels endless and the pressure piles up, a quick jog or a few sets of dumbbells might seem like a luxury. Yet a fresh study published in PLOS One suggests that even modest amounts of movement could be a powerful antidote to the gloom that haunts many college campuses.

The researchers tapped into the 2022 Students’ Health and Well‑being Study, a nationwide survey that gathered data from a staggering 53,362 Norwegian students aged 18 to 35. Participants reported how often they exercised, how intense the sessions were, and roughly how many hours they logged each week.

Almost a year later, a subset of those students completed a clinical interview – the CIDI 5.0 – to see whether they met criteria for a major depressive episode or generalized anxiety disorder. The numbers were telling: students who logged at least 2.5 hours of exercise weekly were noticeably less likely to receive those diagnoses.

Women who never broke a sweat were about 15 % more likely to be diagnosed with depression or anxiety compared to those who exercised daily. For men, the gap was even wider – the risk more than doubled when they skipped regular workouts.

What’s more, the sweet spot for women appeared around five to six hours of activity each week, while men kept seeing their risk drop all the way up to about ten hours.

Local gym‑goers echo the findings. “After a long day at work, hitting the gym just clears my head,” says Isael Duran, a regular at a Fresno fitness center. “It relaxes me and makes me feel better about myself.” Diane Brown adds, “I like going in the morning. It sets a positive tone for the whole day – I feel productive right from the start.”

Both agree that newcomers don’t need to start with marathon sessions. “You don’t have to go big,” Brown advises. “A little bit, consistently, is better than a huge effort that burns you out.” Duran concurs, “Just keep showing up. After a while it becomes second nature, and you start looking forward to it.”

While the study focused on Norwegian students, the take‑away feels universal: moving your body, even in small bursts, may act as a buffer against the mental strain many young adults experience. The researchers caution that exercise isn’t a cure‑all, but it’s a low‑cost, accessible tool that can complement other mental‑health strategies.

So the next time you’re tempted to skip a workout, remember that those extra minutes might be doing more than just shaping your muscles – they could be safeguarding your mood, too.
