The world's oceans contain roughly 97% of Earth's water, but surprisingly, they are not the saltiest bodies of water. Instead, some smaller, geographically isolated lakes hold the record for extreme salt concentrations. This fact raises a fascinating question: which water contains more salt?

According to the World Health Organization, consuming the recommended amounts of salt can prevent 2.5 million deaths annually, highlighting the significant health impact of sodium intake. While many people focus on reducing salt, a popular trend suggests adding it to water for hydration.

Normal saline, a sterile solution used widely in medicine, has a precise 0.9% salt concentration, matching the salinity of our body’s fluids. While commercial options are best for sensitive applications, understanding how much salt do I need for saline can be invaluable for creating safe, temporary solutions for minor issues at home.

While the Earth is covered by more than 70% water, over 97% of it is saltwater, undrinkable by humans. Understanding why our bodies cannot process this vast ocean resource is critical for survival and general knowledge.

Adding salt to water changes its physical properties in several fundamental ways, a phenomenon that has profound implications for everything from cooking to the natural world. These alterations, known as colligative properties, are influenced by the concentration of salt ions dissolved in the water.

According to the World Health Organization, most adults already consume more than the recommended daily maximum of 5 grams of salt, primarily from processed foods. Adding too much salt to your water can exacerbate this problem, leading to serious health complications like severe dehydration and dangerous electrolyte imbalances.

As the third most abundant element dissolved in seawater, magnesium is a fundamental component of the ocean's chemical makeup. This essential mineral is not merely a passive part of ocean water but plays an active, indispensable role in global marine ecosystems and has significant industrial applications.

Did you know that despite being immersed in water, competitive and recreational ocean swimmers face a significant risk of dehydration? The high salt content of the ocean, rather than hydrating you, can actually lead to fluid loss and health issues if you’re not properly prepared.

With an average salinity of about 3.5%, seawater contains a concentration of dissolved salts that is dangerously high for human consumption. While a small, accidental gulp of seawater is not harmful, relying on it for hydration leads to severe dehydration and puts immense strain on the body's vital organs. This biological fact is a crucial aspect of survival at sea, explaining why even when surrounded by water, a person can die of thirst.

A study published in the *Journal of Clinical Periodontology* indicates that saltwater mouth rinse has anti-inflammatory effects comparable to a 0.12% chlorhexidine rinse following periodontal surgery. The use of saltwater as a therapeutic agent for inflammation has a long history.
