Exercise has a significant positive influence on the body's immune response. Engaging in regular physical activity can enhance the circulation of immune cells, enabling them to perform their functions more efficiently. Moderate exercise may increase the body’s production of antibodies and create an immune system that is more resilient against infections. Furthermore, exercise reduces stress, which can suppress the immune system. However, it’s essential to balance intensity, as excessive exercise might lead to temporary immunosuppression. Ultimately, a consistent exercise routine supports a stronger and more effective immune defense.
