Which type? A huge definition range: whirlpool, hot tubs, hot springs, pool therapy, cold baths. Overall the greatest use would be relaxation. But pools allow weight removed exercize and lowest impact aerobics. Possibly as a carrier for herbal/aroma therapy. Wound care: only to clean a dirty wound once. Be cautious of temp. In any use(neuropathy or raynauds risks) discuss it with a physiatrist for more.
