Sea water has a higher concentration of solute than do human body cell. Why might drinking large amounts of sea water be dangerous?

Drinking large amounts of seawater is dangerous because it contains a high concentration of salt, which can lead to dehydration. When seawater is ingested, the body's cells will lose water to the surrounding seawater through osmosis in an attempt to balance the solute concentrations. This can result in increased thirst, kidney strain, and potentially life-threatening conditions such as kidney failure or hypernatremia. Ultimately, it can exacerbate dehydration rather than alleviate it.
