What happens to the immune system with regular exercise?

Regular exercise has a positive impact on the immune system, making it more efficient in various ways. Engaging in physical activity helps improve circulation, which allows immune cells to navigate the body more effectively to identify and combat pathogens. Exercise also promotes the circulation of fluid in the lymphatic system, aiding in the removal of toxins and waste from the body.

Additionally, moderate exercise has been shown to enhance the immune response by increasing the production of various cytokines and antibodies, which play critical roles in immunity. Regular physical activity can lead to a reduced risk of chronic diseases, thereby promoting overall health and a more robust immune response.

In contrast, excessive or intense exercise without adequate recovery may temporarily suppress immune function, but this is not the case with regular, moderate exercise. Therefore, regular exercise leads to an efficient and well-functioning immune system, enhancing the body’s ability to fend off infections.
