Electrolytes refer to salts and other chemicals that are dissolved in body fluids, which play a crucial role in various physiological functions. These substances, such as sodium, potassium, calcium, and magnesium, are vital for maintaining fluid balance, transmitting nerve impulses, and ensuring proper muscle function, including the contraction of heart muscles.

In the context of hydration and health, electrolytes help regulate the body's blood pressure, pH levels, and the overall balance of fluids within cells and tissues. Their proper concentration affects nerve conduction and muscle contraction, making them essential for physical performance and overall bodily functions.

Understanding electrolytes is particularly important in fields such as firefighting, where maintaining hydration and physical performance under strenuous conditions is critical. This knowledge helps ensure that fire fighters can perform their duties effectively and safely, even in high-stress situations.
