The immune system plays a crucial role in recovery from exercise by repairing tissue damage and fighting off infections. Strenuous workouts create micro-tears in muscle fibers, and a well-functioning immune system is essential for the repair process. Components such as white blood cells and cytokines help facilitate recovery and promote overall health. Regular moderate exercise can enhance immune function, but excessive training without adequate recovery can suppress immunity. Balancing exercise intensity with rest is essential for optimal recovery and long-term health.
