Hydration plays a crucial role in biological processes, as water is essential for numerous physiological functions. It acts as a solvent, facilitating biochemical reactions, transporting nutrients, and removing waste products. Water also helps regulate body temperature through perspiration and provides structural support to cells. Adequate hydration is vital for maintaining overall health, as dehydration can lead to impaired physical and cognitive functions, increasing the risk of various health issues. Understanding the importance of hydration is essential for optimal performance and well-being in both daily life and athletic activities.
