There are dozens of papers in the medical literature on the effects of
*head-out-water-immersion* on vasopressin levels, atrial natriuretic factor,
and sympathetic nervous system activity. There has been research on
the effect of sympathectomy on immobilization osteoporosis so my guess
is that there *may* be a cause-and-effect relationship between the swimming
and the decreased bone density.
