Excessive drinking beyond thirst during exercise can lead to exercise-associated hyponatremia, a condition that occurs when there is an imbalance of electrolytes in the body, particularly sodium. This happens when a person consumes more fluids than their kidneys can excrete, diluting the sodium levels in the bloodstream.

The body requires a certain concentration of electrolytes to function properly, especially during physically demanding activities. When sodium levels drop too low, it can result in symptoms such as headache, confusion, seizures, and in severe cases, can be life-threatening. This highlights the importance of not only hydrating but also being mindful of how much fluid is consumed relative to the needs of the body during exercise.

While hydration is crucial for performance, over-hydration can negate the benefits, leading to this serious condition instead of improved performance or reduced muscle soreness. Balancing fluid intake with electrolyte levels is key to maintaining overall health and performance during exercise.
