Ask the doctor. I spend part of every summer on the coast of Maine. One of the things I love to do there is swim in the ocean for 20 or 30 minutes. The water is cold (55° F) but I don't mind. I'm almost 80. I had my mitral valve repaired five years ago, and my heart rate is sometimes irregular. Are my cold-water swims okay for my heart?
