Ward off colds on the boardwalk

You probably spent many summer days strolling the beach, downtown shopping district or local mall. And putting on your walking shoes again helps lower your risk of developing a cold or other upper-respiratory infection.

Physical activity stimulates the immune system, helping it provide more robust protection.
