Electrolyte balance is crucial for maintaining proper bodily functions, as electrolytes like sodium, potassium, and calcium help regulate nerve and muscle function, hydration, and blood pH levels. An imbalance can lead to symptoms such as muscle cramps, fatigue, and irregular heartbeats. To maintain electrolyte balance, it's important to consume a diet rich in fruits, vegetables, and fluids. Activities that cause excessive sweating, such as intense exercise, can deplete electrolytes, making it essential to replenish them through hydration and electrolyte-rich foods or drinks.
