I have been a hydrotherapy "fanatic" for most of my professional career, and personally, also. But not just the hot water soak. The article didn't go far enough. In a therapeutic pool, the hydrostatic pressure of the water if you are standing chest deep is great enough to push fluid up from you feet, ankles, and legs to thoroughly and significantly treat your vascular system. And you can stretch tissues, muscles and joints in the water to a far greater extent in the water than you can on land. I used to suffer from fibromyalgia (admittedly self-diagnosed), but successfully treated it with 4 x week pool exercise therapy. Warm water soaks will also heal minor wounds and clear up minor skin infections.
