👉 Dive fluid, commonly known as diving saltwater or diving oil, is a specialized solution designed to minimize the formation of bubbles around a diver's body during underwater activities. Typically composed of sodium chloride (table salt) and sometimes other additives, this fluid works by reducing the surface tension of the diver's skin, which in turn decreases the size and number of bubbles that form when the diver exhales underwater. This not only enhances visibility for the diver but also reduces drag, making movements more efficient and safer. Dive fluids are essential in recreational diving and technical diving to ensure both the diver's comfort and the clarity of underwater visibility.
