Cold water therapy in your above ground pool

This weekend was the Annual Rock n Roll Marathon in San Antonio. My usual routine after a long run was to soak in the bathtub with about 40 lbs. of ice. It reduces the inflammation and helps with a quicker recovery. This weekend after the half marathon I was too lazy to go buy the ice, so I thought I would try the pool. The pool water temperature was 66F. I walked around the pool for about 15 minutes and seem to gotten the same effects as a ice bath. Cold water therapy can boost immune function, decrease inflammation and pain, and increase blood flow and metabolism.
