Regular exercise enhances the immune response by promoting circulation and facilitating the movement of immune cells throughout the body. Engaging in moderate exercise has been shown to increase antibody and white blood cell production, which are crucial for fighting infections. Furthermore, physical activity helps reduce levels of stress hormones, which can suppress immune function. However, it's essential to balance exercise intensity; excessive or intense workouts may have a temporary negative effect on immunity. Overall, regular moderate exercise supports a robust immune system and promotes overall health.
