What is one effect of regular physical activity on immune function?

Regular physical activity can significantly enhance immune response, which is a critical component of overall health and wellness. Engaging in consistent, moderate exercise has been shown to promote the circulation of immune cells in the body, improve the body's ability to fend off infections, and reduce the risk of chronic diseases. Exercise can also influence the levels of various immune system hormones, leading to a more responsive immune system.

Moderate activity results in temporary increases in the circulation of immune cells, allowing them to perform their functions more effectively. Over time, this consistent engagement in physical activities helps build a stronger immune system, making the body more resilient against diseases and infections. Additionally, regular exercise is associated with reduced inflammation, which plays a role in various health issues.

Other options, such as decreased muscle strength or increased fatigue, suggest adverse effects, which are contrary to the benefits typically associated with regular physical activity. Moreover, the assertion that there is no effect on health overlooks the significant positive impacts regular exercise has on both physical and mental well-being, specifically related to enhanced immune function.
