Regular exercise positively impacts the immune response. Moderate physical activity can enhance circulation, facilitating the transport of immune cells throughout the body. This boosts the immune system's ability to detect and combat pathogens effectively. Additionally, regular exercise reduces inflammation, contributing to overall health. However, excessive or prolonged exercise can suppress immunity temporarily, making individuals more susceptible to illnesses. Striking the right balance is essential for maintaining a robust immune system, highlighting the importance of consistent, moderate exercise as a health intervention.
