Imagine creating a small-scale tsunami inside your own body—that’s what happens when you practice extreme overhydration. A nephrologist explains that flooding your system with too much water can overwhelm your kidneys and disrupt the delicate internal environment, with potentially severe consequences.
Our kidneys are the dams and filters of our internal fluid system. They are built to handle a normal flow, which for most adults is about two to three liters of fluid per day. This allows them to manage waste and electrolytes effectively.
When you drink an excessive amount, you create a surge that these dams struggle to control. The kidneys work furiously to release the excess water, but in the process, essential electrolytes like sodium can be washed away, leading to a critical imbalance.
This imbalance is known as hyponatremia. It causes the body’s cells to swell with water, a process that is especially dangerous in the brain. The resulting pressure can lead to neurological symptoms, including confusion, seizures, and a medical emergency.
While people with high physical exertion levels need more fluid, they must also be cautious. For everyone else, the message is clear: avoid the internal tsunami. Drink in response to thirst, and trust that your body knows how to maintain its own perfect balance.
