Electrolytes are vital for maintaining proper hydration in the body. They are minerals such as sodium, potassium, and magnesium that help regulate nerve function, muscle contractions, and fluid balance. During physical activity, electrolytes are lost through sweat, and replacing them is essential to prevent dehydration and maintain performance. An imbalance can lead to symptoms like fatigue, cramps, or even more severe conditions such as heat exhaustion. Thus, ensuring adequate electrolyte intake, particularly during intense exercise or in hot climates, plays a significant role in sustaining overall health and athletic performance.
