Regular exercise can significantly impact immune function by enhancing the body's ability to ward off infections. Physical activity promotes healthy circulation, which helps immune cells efficiently travel through the body. Moderate exercise has been shown to reduce inflammation and promote anti-inflammatory cytokines, contributing to a balanced immune response. However, excessive exercise may have the opposite effect, potentially suppressing the immune system. Overall, maintaining a consistent exercise routine supports improved immune resilience and promotes overall health, especially during cold and flu seasons.
