Exercise impacts immune function and overall well-being by boosting the body's immune response and enhancing overall health. Regular physical activity encourages circulation of immune cells, reducing the risk of illness. Exercise is also associated with lower levels of inflammation and improved mood due to the release of endorphins. Furthermore, maintaining a consistent exercise routine can contribute to long-term benefits, including reduced risk of chronic diseases and improved mental health, fostering a better quality of life and resilience against illnesses.
