A large Norwegian cohort study following more than 32 000 adults for eight years found that people with better cardiorespiratory fitness were less likely to start using anxiolytic or antidepressant medication. Even moderate, regular physical activity, brisk walking, cycling or any exercise that raises heart and breathing rates, appeared to confer this protective effect. Researchers suggest several biological pathways: repeated aerobic effort boosts “pleasure” molecules such as endogenous opioids and endocannabinoids, lowers the stress hormone cortisol, improves sleep quality and encourages social interaction and self-esteem.
Complementary evidence from an international meta-analysis published in JAMA Psychiatry shows that as little as 15 minutes of brisk walking a day (about 75 minutes a week) can reduce depressive symptoms by roughly one-fifth, with greater benefits at higher doses of activity. Taken together, these findings position regular movement not only as a preventive measure but also as a valuable add-on to conventional treatment for anxiety and depression.
