We keep being told how dangerous open water swimming is. But there must be health advantages and disadvantages. Pluses are the life-enhancing effects of exercise, getting into the out-doors, lowered stress levels, etc. Disadvantages include the risk of drowning, water borne diseases, etc.
I have the mortality statistics for 2005 in front of me, and the numbers of water related accidents are quite low. Deaths due to the health problems that will be affected by physical exercise (e.g. heart disease) are very high, heart disease being the largest cause of death overall.
So by regularly swimming in open water, you have an increased risk of some rare causes of death, but reduced chance of the most frequent cause of death. While I haven't got any numerical examples, I cannot believe that the disadvantages outweigh the advantages.
