There is more salt water on Earth than freshwater, says the water mavens from Green Water Technologies. But for all its benefits, including recreation, there is one important thing saltwater simply can’t do and that is sustain human life.
Q: Why can’t humans drink salt water?
Green Water Technologies: While salt is a necessary nutrient, too much or too little can wreak havoc on the body’s operating system. It can essentially cause the body to dehydrate and shut down.
Q: Doesn’t the body have a way to stabilize sodium?
Green Water Technologies: At a cellular level, yes. The body is capable of stabilizing some salt and prevent excess from entering our cells since each cell is outfitted with a semipermeable membrane. However, semipermeable is not impermeable and, under enough pressure, salinated water can replace the cell’s water content.
Q: But why is drinking saltwater fatal?
Green Water Technologies: If you consume saltwater in lieu of freshwater, your body is essentially experiencing a net loss of hydration due to the above-mentioned semipermeable membrane of the body’s cells. As the body tries to compensate for this fluid loss, your heart rate increases and blood vessels constrict in an effort to maintain each organ’s blood pressure.
Q: What are some signs of dehydration?
Green Water Technologies: The first indication that the body needs water is simply thirst. Beyond that, dry mouth and fatigue are common. Other effects of excess sodium intake include muscle cramps and, eventually, organ failure. Dehydration is treated only by replenishing the body’s store of usable water. If you are dehydrated, avoid drinking coffee, tea, and other diuretic fluids. Instead, opt for plain water or sports drinks enhanced with electrolytes.
