Sea water is known to have antiseptic and stimulating effects, especially when treating wounds. Also used to re-mineralize the skin
Seawater is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5%. This means that every kilogram, or every litre, of seawater has approximately of dissolved salts (mostly, but not entirely, the ions of sodium chloride: , ).
About 71% of the globe is covered by sea water, which supports about 250 000 species of marine organisms. By distributing heat through ocean currents, sea water is an important regulator of climate.
