Which statement is a myth regarding hydration?

The idea that "you can't drink too much water" is a myth because it overlooks the potential dangers of excessive water consumption, also known as hyponatremia or water intoxication. While staying hydrated is crucial for overall health, especially during exercise, there is a point at which drinking too much water can dilute the sodium levels in the bloodstream, leading to serious health issues. Thus, moderation is key when it comes to water intake.

Understanding this concept reinforces the idea that while hydration is important, it must be balanced to ensure safety and health. The other statements about hydration present more accurate representations of hydration practices; for example, that water can be more effective than sports drinks in certain situations, and that soda is not an ideal choice for rehydration due to its sugar and caffeine content. Additionally, hydration before workouts can help improve performance and prevent dehydration during exercise.
