The relationship between exercise and immunity is significant, as regular physical activity can boost immune function. Moderate exercise enhances circulation, promoting the efficient transport of immune cells throughout the body. It may also reduce chronic inflammation and improve overall health, lowering the risk of infections. On the other hand, excessive or intense exercise without adequate recovery can suppress immune function, increasing susceptibility to illness. Balancing exercise intensity and recovery is vital for optimizing health. Overall, maintaining an active lifestyle contributes positively to immune health and resilience.
