Survival guides have warned against it for centuries, and for good reason: consuming excessive salt water, like seawater, is incredibly dangerous and counterintuitive to hydration. This is because the high salt concentration forces your body to expend more water than it takes in, leading to accelerated and life-threatening dehydration.

Over 70% of the Earth is covered in saltwater, yet consuming it is harmful to the human body. So, what happens if you swallow salt water at the beach? While a small, accidental sip is usually harmless, ingesting larger quantities can lead to dehydration, kidney strain, and other serious health problems.

The human body requires a delicate balance of sodium to function, but seawater contains a salt concentration of roughly 3.5%, far exceeding what our kidneys can process. This is precisely why you shouldn't drink salt water from the ocean, as it triggers a dangerous physiological process that leads to fatal dehydration.

Over 96% of the planet's liquid water is ocean water, yet drinking it can be deadly for humans. This biological paradox exists because the human body is not equipped to process the high concentration of sodium chloride found in seawater, leading to a process that ultimately causes severe dehydration, not hydration.

According to the National Oceanic and Atmospheric Administration, seawater is, on average, about 3.5% salt by weight, a concentration far too high for human consumption. So, why shouldn't we drink salt water, even in a desperate survival situation? The answer lies in our body's delicate physiological balance, which seawater actively disrupts with potentially fatal consequences.
