Electrolytes play a vital role in hydration for athletes by helping to maintain fluid balance, supporting muscle function, and regulating nerve impulses. During intense exercise, electrolytes such as sodium, potassium, and magnesium are lost through sweat. Replenishing these minerals is critical to prevent dehydration, muscle cramps, and fatigue. Adequate electrolyte intake ensures optimal performance and recovery, as they aid in muscle contractions and prevent imbalances that could impair athletic abilities. Athletes should consume electrolyte-rich foods or drinks to support their hydration needs during and after exercise.
