Detailed explanation-1: -The sea water is far more concentrated than our body cells. So if one drinks sea water, his cells will rapidly lose water as our body cell is also a semipermeable membrane and as a result it allow water to go out of the cells. This will cause dehydration and the cells will shrink.

Detailed explanation-2: -If there’s too high a concentration of salt coming in, the cells force out extra water to maintain balance, basically wringing themselves out. They stop functioning, you stop functioning.

Detailed explanation-3: -Saltwater itself is not bad for your skin, but constant exposure to a combination of salt, sun and sand can irritate and dry out skin, especially for those with a history of dry skin or other issues like eczema.

Detailed explanation-4: -Saltwater may benefit the skin because it contains minerals, such as magnesium, potassium, and calcium, and may have antibacterial properties. Deep sea water may help certain skin conditions, such as eczema and psoriasis, although this may be due to the high nutrient content rather than salt.
