Water is an integral part of our lives, and its role in maintaining life is undoubtedly important. However, despite the abundance of oceans and seas, sea water is not suitable for drinking due to its high salt content.
The publication writes about this “Live Science”.
Sea water is so saturated with salt that our kidneys are unable to process it effectively. Approximately 3.5% of the weight of seawater is dissolved salt, and if it were removed and distributed evenly over the land surface, it would create a layer of salt more than 166 meters high. This salinity exceeds the level that our cells can safely process, since water is required in a relatively pure form to maintain their functions.
When we drink salt water, our body absorbs excess salt and needs to consume even more water to remove it. The kidneys filter impurities from the water, but the urine they produce is less salty than seawater. Thus, drinking salt water not only does not quench your thirst, but can also lead to dehydration and even death.
Some marine animals, such as seabirds and mammals, have developed special adaptations that allow them to drink salt water. However, most land animals, including humans, have evolved to obtain water from fresh sources. This is because our primate ancestors evolved to adapt to environments where fresh water was more readily available, which left its mark on our ability to absorb fluids.
Thus, salt water, despite its greatness and attractiveness, remains unsuitable for human drinking due to its high salinity, which exceeds the acceptable level for our bodies.
