Can exercise boost immunity?
Disease description:
Hello doctor, I read online that exercise can boost the immune system. Is this true? I've always had poor health and frequently catch colds since childhood, so I'd like to know whether exercising can really improve immunity. If it's true, I'm willing to give it a try and make a change for myself.

Yes, exercise can boost the immune system. Physical activity stimulates the immune system, prompting the body to produce white blood cells and antibodies, thereby enhancing its ability to resist diseases. Research shows that people can more effectively fight off viral infections after engaging in aerobic exercise. Additionally, aerobic exercise can increase levels of serum immunoglobulin A (IgA), making cells more sensitive to antigens and thus effectively defending against external pathogens. At the same time, moderate exercise can suppress the release of stress hormones, reduce the impact of stress, and strengthen the body's disease resistance. In summary, appropriate exercise can help enhance immunity and protect against viral infections.
