Deep Ocean Water: Is It Really Superior for Athletes and Health?

There's a common belief that deep ocean water contains unique minerals and compounds that enhance athletic performance and overall health. However, is there truth to these claims, or is it nothing more than another health myth? Let's dive into the facts.

Mineral Content in Ocean vs. Regular Water

The presumptions about deep ocean water being fundamentally different from regular water are largely unfounded. Regular water covers about 90% of the Earth's surface, and most of it lies beneath the surface. Even the water not falling from the sky or in clouds usually contains dissolved minerals.

According to health experts, the human body requires various minerals for optimal function, primarily obtained from food. While a few minerals may be found more abundantly in water, the majority of minerals in the Earth's water, including ocean water, are sodium (salt), which our bodies need only in very small amounts—typically milligrams per day at most.

Table Salt vs. Sea Salt

The minerals in deep ocean water are more similar to table salt (sodium chloride) rather than unique compounds beneficial to health. It is crucial to understand that consuming too much salt can be harmful, potentially leading to serious health issues such as kidney failure.

Health Risks of Drinking Deep Ocean Water

Some sources claim that deep ocean water is a pristine, mineral-rich resource perfect for athletes and health enthusiasts. However, reality is far from this. Ocean water, including deep ocean water, is not just highly saline but also contains significant amounts of toxic substances like heavy metals and pollutants.

Runoff from land, coastal activities, and other human interventions often lead to the accumulation of toxic waste in ocean water. As a result, drinking deep ocean water can be hazardous. The U.S. Geological Survey (USGS) explains that seawater is toxic because the human body cannot effectively excrete the salt present in seawater. The kidneys can produce urine, but they need freshwater to dilute the salt effectively.

When there is too much salt in the body, the kidneys cannot obtain enough freshwater, leading to a failure that can be fatal. Even small amounts of certain minerals like selenium or potassium can be lethal in seawater. Therefore, sticking to fresh water is advisable for both health and athletic performance.

Conclusion

While ocean water does contain minerals, deep ocean water is not a source of unique or superior minerals for athletic performance or general health. The high salt content and toxic waste make it hazardous to consume. For athletes, fresh water remains the best choice. It ensures proper hydration and electrolyte balance without the risk of toxic contamination or potential harm from excess minerals.
