Dear 小畫家, Doing exercise enhances immunity because 1) it increases metabolic rate that increases the excretion of wastes and the production of blood cells. 2) it promotes the transport of circulatory system as well as lymphatic system which carry white blood cells to fight against diseases. 3) it relieves stress psychologically that improves the function of our bodies.
