Dive in for joint health

Swimming can keep your joints flexible, reduce stiffness, and increase mobility.

When you were a kid, swimming was no doubt a favorite summertime activity. Now, it may be one of the best ways to keep your older joints healthy.

"As a low-impact activity, swimming places minimal stress on the joints," says Sarah Ellison, an aquatic physical therapist with Harvard-affiliated Spaulding Rehabilitation Network. "The buoyancy of the water allows you to move limbs and joints more easily through their normal range of motion. This helps joints remain supple and improves overall flexibility."
