Exercise is closely linked to immune function, enhancing the body's ability to fend off infections. Regular physical activity can lead to improved circulation and increased production of immune cells, helping to detect and fight pathogens more effectively. Moderate exercise, such as walking or cycling, is particularly beneficial and can help reduce inflammation while boosting antioxidant levels. However, excessive or high-intensity workouts may temporarily suppress the immune response. Balancing exercise with proper rest aids in maintaining a robust immune system and overall health.
