Physical activity has a profound positive impact on immune function. Regular exercise enhances the circulation of immune cells, aiding their movements through the body and enabling quicker responses to pathogens. Moderate-intensity activities, such as walking or cycling, can reduce inflammation and promote better overall health. Moreover, consistent physical activity is associated with a lower risk of chronic diseases, which, in turn, supports immune system efficiency. Therefore, incorporating regular exercise is essential for individuals aiming to boost their body's natural defenses and maintain long-term health.
