That’s interesting. In the past, for those of us living near the ocean, salt water was an observable protection against infections.
Salt water is usually fine. The problem is usually standing salt water on the land near the ocean. It’s an area where bacteria can thrive. I’ve known people to get very ill from it.
Even polluted lake water is very good about cleaning up wounds. Mostly due to the microorganisms in the water that love to eat bacteria. The wounds would also heal leaving no discernible marks.

That was before we had a better understanding of bacteria. Vibrio Vulnificus wasn’t even discovered and isolated until 1976, and it was largely because of improved lab equipment technologies that we started discovering that bad bugs could thrive in salt water. When my dad was in Vietnam, Army doctors told them to go swim in the surf when they got R&R time at the beach. Just as you said, they thought it would heal wounds. Now they know just how dangerous natural bodies of water are to open wounds.
And sea water is a heck of a cure for poison ivy rash.
