A new systematic review and meta-analysis published in the American Journal of Preventive Medicine found that regular physical activity is associated with significantly lower risk of anxiety disorders. The study examined data from over 80,000 adults and found that physically active individuals had approximately 13% lower odds of experiencing anxiety symptoms and more than 30% lower risk of developing any anxiety disorder. For generalized anxiety disorder, the most common type, the risk was nearly 50% lower among those who exercised regularly.
The analysis included a broad range of physical activities—from walking to cycling to yoga—with the protective effect consistent across activity types. The study defined physical activity as any movement raising energy expenditure above resting levels, including both structured exercise and daily-life movement. Researchers emphasized that “the more they moved, the lower their risk seemed to be,” and the relationship was dose-dependent, with greater amounts of physical activity associated with greater risk reduction.
Several mechanisms explain the protective effect. Exercise helps regulate the body’s stress response by balancing cortisol levels, triggering the release of endorphins and brain-derived neurotrophic factor (BDNF), a compound that promotes neuroplasticity. Behavioral factors also play a role: movement provides structure, social connection, and a sense of mastery, which may reduce rumination and anxious thoughts. The findings held even after controlling for factors such as age, sex, and existing health conditions.
Experts recommend aiming for at least 150 minutes of moderate or 75 minutes of vigorous activity per week, though the researchers noted that smaller amounts, such as a 10-minute brisk walk, can still benefit the nervous system. The study emphasized that “the key factor was consistency, not intensity.” Strength training also contributes by regulating blood sugar and reducing inflammation, which influences mood. The findings suggest physical activity may serve as an accessible preventive tool against anxiety, with potential to reduce the burden of anxiety on a population level.
