What can excessive water intake lead to?

Excessive water intake can lead to water intoxication, which occurs when an individual consumes an excessive amount of water in a short period, leading to a dilution of electrolytes in the body. This dilution can disrupt the balance of sodium in the bloodstream, causing cells to swell. The symptoms of water intoxication can range from mild, such as headaches and nausea, to severe, potentially resulting in seizures, coma, or even death in extreme cases.

Understanding the mechanisms behind water intoxication highlights the importance of maintaining proper hydration levels without overconsumption, as the body requires a balance of fluids and electrolytes to function optimally. This condition is particularly risky for individuals who engage in intense exercise or consume large amounts of water without adequate electrolyte replenishment.
