The impact of overhydration on athletic performance can be detrimental, potentially leading to hyponatremia, a condition characterized by low sodium levels in the blood. This imbalance can cause symptoms such as confusion, headaches, and muscle cramps, significantly impairing performance. While staying hydrated is essential, excessive fluid intake can dilute electrolyte levels, affecting muscle function and endurance. Athletes should focus on achieving a balance, rehydrating appropriately based on activity levels and environmental conditions, ensuring optimal performance and safety.
